Knex Construction?

Hello everyone, I am thinking of building something from knex, but I do not have the slightest idea how. Basically I want a stand that will hold my DS, psp, two ds games, and three psp games. I think the psp and ds will just sort of dock/hang on the sides of the stand, the bottom of the stand will be risen as to reduce dust, and improve looks (aka legs), and the area for the five games will be divided to provide two different depths. Moreover, there needs to be a front piece to keep the games from falling out of the front. Perhaps a tilt to the back would be nice. Let me know what you think and any ideas you have. Thanks!

Willing to Construct Projects

Hello everyone. I'd just like to offer the service of project construction. I know a lot of people have great ideas that they want someone to make for them. I would be willing to make these projects. I am pretty good at soldering and know about how to construct circuits (I can do electronics). I don't know how good I am at other types of projects or what people would want, so just ask! Finally, I'd be willing to construct these for free on just one condition. I'd like to be able to sell kits of what ever the project is. I'm looking to open up an online store and need some projects to do. Even if you don't want me to sell it I probably would still do it for free. Thanks, and someone please have a project! :-)

Solar Panel Construction

Hello Everyone, this is my first forum post!I had a question and couldn't think of a better place to turn to than this.Basically, I am constructing, or planning to rather, an outdoor picnic table. I want to add some gadgetry to it and make it more multifunctional. Sorry to be vague, but a lot of it is still being worked out and since I'm going to post the project on here anyway, I'd like to wait to present the entire project as a whole.My question involves the use of solar panels as a table top surface. I have a basic understanding of how to create a solar panel powered system (http://www.rain.org/~philfear/how2solar.html or https://www.instructables.com/id/Solar-Power-System/). But my question is this: does covering the solar panel with a piece of acrylic hinder its power collecting abilities? I'm thinking of covering the entire table top surface of my table with solar panels. Aside from the obvious downfalls of people using the table and blocking sun, I thought there would be enough time when its not in use to collect power. But obviously I can't have people eating right on the panels and damaging them. Any guidance would be GREAT! I just want to know if I should even entertain this design idea or separate the panels from the table altogether. Thanks!

Fighting construction toy

I am trying to find a toy that my brother had as a kid. What it is was a battery powered base that you put a spinning blade like object it was all made of plastic, on top of the blade was a plastic shield like object to hold the blade on, the two motor bases where connected together with string that came out the side of the robot and connected to a plastic anchor point of the other. When you turned on the two bases it caused the blades to spin and the tether lines slowly retracted causing the blades to come into contact which then knocked the shields and blades off each other. The person who still had their blade and or shield on at the end won. Does anyone know what these toys where called?

Construction ideas for this concept?

Recently, I have been working on a gas 'vaporizer' that evaporates gas before being fed into an engine. During my short-term experiment, I found that this saves ~70% (+-20% for crudity of measurement.) This works because the vapors will burn more thoroughly and cleanly, leading to higher apparent efficiency. Below is a basic diagram of how the system works. You can see there is a container that is half-full with gas, and a hose goes down with many small holes. As the engine's compression draws a vacuum on the container, air will come up through the holes. As it rises, the gas-air surface area rises dramatically, leading to the vaporization of gas. To further increase the surface area, I also added a felt liner on the inside to allow the gas liquid to rise and evaporate. The final mixture ends up very rich, so to compensate, a 'T' fitting has been added to allow air to mix in with the vapors/fumes. Some valves have also been added to control the air inlet (similar to a 'choke') and the amount fed to the engine (similar to a throttle. In fact, it is possible to use the original throttle or choke as a throttle on the carburetor on my tractor!) The problem is: My original design utilized a plastic folgers coffee can, and the flimsy plastic top was hot glued to a thicker plastic cutout for strength and support. Since most glues will dissolve in gasoline, including hot glue, it could not be used. most did not hold anyway. I also tried JP weld plastic cement and it did not hold at all. I had to trash this build. I did, however, get enough use to run the tractor for several minutes while testing gas use. I found that the tractor used nearly twice as much simply running on gas than the fumes. I did not have the float valve and electric pump hooked up with the prototype. Also the 3/4in housing I used may be a bit constrictive and also seems to get slightly damaged by the gas. It will not be a long-term solution.  So I need to redesign the project, and I am thinking of using a 1-3 gallon bucket that is sealed or a gas tank. I need good almost air-tight seals on everything. I am asking for any ideas related to the construction of this device and any tips you may have.

Looking for constructive critism

I have not written an 'ible in a long while, but was recently so inspired I wrote...   https://www.instructables.com/id/Make-A-2D-Infinite-Runner-with-Unity/ Luck would have it that a game contest opened during my building of the first prototype (pre write up, to get things all worked out), which spurred me on even more. Anyways, I am wondering how I missed the mark completely, not even worth a feature. I have had way lesser projects featured....and well, I was only inspired to write this to share. Anyone who has been writing here for any amount of time knows that you need to be featured to be seen. I gave detailed step by step instructions with many pictures well commented...or thought I did. I did something original (Not many game making tutorials here, only 2 other unity ones, and they are on older versions.) I thought the demo game download was a nice touch.  So I am curious for suggestions on how I could spruce it up enough to be considered as a feature. I believe that people would enjoy the topic, and more importantly, I feel people would like to make this or use this as a springboard to their own version. Was using the robot a big faux pas? I see so many other features that use him and thought it was a good idea. Is the game itself that visually unappealing? Perhaps foolishly , but I love the look....I was...even more foolishly...proud of it. It wasn't something I just knocked out, but rather something that a lot of time went into. Time that was truly wasted if it is never even seen. Discouraged. Any suggestions  to how to make it better would be welcome.

Help in constructing a battery charger

Hi there! I need some help constructing a circuit to charge a lead acid battery. The ratings of the battery are: 12v, 7Ah(Or so). The circuit must have the following features: -> Must be fairly simple (Considering the fact that i don't get all the components easily in the place i live, not even online) -> Must automatically cutoff when the battery is fully charged(Or near full). -> Must also have an indicator, (like the ones we have in a digital camera battery charger, which shows RED LED=Charging, GREEN LED=Full, something like that). -> Charging times can be fairly reasonable (Few hours for a full charge sounds reasonable).  -> Hopefully, some explanation on how the circuit works. ;) Thanks in advance :)

Getting Started 1.1 What is Instructables?In a sentence: Instructables is a web-based documentation platform where passionate people share what they do and how they do it, and learn from and collaborate with others. A bit more in depth: It was created by Eric Wilhelm, a mechanical engineer, and launched in August 2005. Instructables is dedicated to step-by-step collaboration among members to build a variety of projects. Users post instructions to their projects, usually accompanied by visual aids, and then interact through comment sections below each Instructable step as well in topic forumsWhile a member of the Media Lab at MIT, Wilhelm co-founded Squid Labs, an engineering and technology company specializing in design and consulting. Instructables started as an internal Squid Labs project, which Wilhelm has since spun out as an independent company and acts as CEO.The original content focused mostly on such projects as building electronic or mechanical devices to solve common problems around the home. The scope of the project has expanded to include a larger array of categories, including arts and crafts, food, home, life, offbeat (first known as "not liable") and recently knex, transportation and tech. The site allows uploading of photos, diagrams, video and animation to help explain complex terminology and mechanisms in clear and understandable termsRead more about the history...Also, Read our About to see who works here1.2 How does the Site make money? Is it profitable?The site is mainly supported by ads, which you see in the sidebars and sometimes at the top of the page. Here is the full explanationIs Instructables profitable? - Almost. According to ewilhelm , the site generates enough money, that it usually covers its running costs, but not quite enough yet to be constantly profitable. 1.3 What is the Instructables Robot?The Instructables Robot is Instructable's mascot. His main function is to greet new members and alert members when they receive comments or messages. The robot is friendly and welcoming. You can easily find him around Instructables.You can tell the robot to alert you if you receive a comment in your personal settings. Likewise, you can tell him to stop doing so anytime at your personal settings.Nobody knows how exactly the robot came to Instructables.....time may tell......1.4 How can I get started here?You probably want to upload an image to your profile. You can do that here , as well as change some of your other account settings, like making View all Steps in one page your default.After that, check out How to make a great Instructable , The Guided Tour of Instructables, and the Help Group if you have any questions.1.5 Who can Help me get started here? ANYONE! all users are helpful. If you are confused, or have a question, don't be afraid to ask in the forum of a member of the community. Our members are happy to help newcomers get comfortable. You are more likely to get lots of help through an open thread, but you can ask questions privately (say, for a project in development) through the "Private Message" system.Have a look at other FAQs in the FAQ Section1.6 What does DIY mean?DIY means Do-It-Yourself. It means that instead of buying expensive stuff, make it yourself and save some money. The main idea of Instructables is to make things and share them with others. You will be surprised about how much money you could save if you do things yourself, and we are here to help you.1.7 What can I write an Instructable about?Bearing in mind our family nature, anything at all. If you're passionate about it, and want to tell others how you do it, then write an Instructable. If you're looking for inspiration, check out the Burning Questions to get you started. When you're a bit more familiarized try entering our Contests1.8 What's the difference between an Instructable and a slideshow?In an Instructable, you show detailed step-by step details on how to make or do something. A slideshow is used when you do not have enough documentation or material for a full Instructable. In a slideshow, you can show off projects or things that you have made. If you want to show something, but its not enough to fill an instructable, you can show pictures of it in a slideshow and write a short summary of the project.1.9 What is a video on Instructables? If you do not want to write a full instructable, but you want to present something that can't be fit into a slideshow, you can embed a video as an individual section.1.10 How can I unpublish my Instructable?It's a slightly-roundabout route, but if you click the edit function, then the publish, and unpublish options appears lower down the screen.2. The Community2.1 How can I make text effects like bold, italic , small text and upper small text?Read this helpful Section by Instructables member NachoMahma2.2 Why doesn't my Instructable show up on the search page when I type the name? Instructables are reviewed by the Robot and his human minions before being added to the public pages. Be patient, it may not have gone through the filter yet. Is your instructable lacking images? Sometimes instructables without images fail to go through the filter.On weekends and Holidays, where there is an influx of people posting projects, it may take longer than normal for it to show up in the Most Recents. If there is a problem with your work, someone on staff will PM you.Your instructable may have been caught by the spam filter. If it has, contact anyone in the Instructable team, and they will check it out for you. Just Be Patient.2.3 What kind of material is considered offensive? What kind of material should be avoided?Pornography - Any and all pornographic material is considered offensive. Posting images or links that include pornography is strictly prohibited. This is a family friendly site, children often browse this site.Language - If you wouldn't show it or say it to your headteacher at school, don't show or say it here.Insults and flaming - We have a "be nice" policy here. Please be positive and constructive with your comments or risk being banned from our site.Spam - Spamming, misleading links and site advertising on the forums, orangeboards, instructables, and Private Messaging are strictly prohibited. However, offers and advertising are allowed in the For Sale Section2.4 Why am I asked to give a number when I send a Private message to someone?This is called a Captcha. A captcha is when you are asked a number or word that appears as an image or sound. The purpose of this is to stop automated spam robots from spamming our Community.2.5 Can I ask for homework help on the forums?Of course! Our community is more than happy to help any way possible! Be sure to post in in the right category, because you wont get much science help in our craft section!2.6 How can I improve the community?You can help our community in many different ways:Be positive and constructive in your comments. We are a friendly and welcoming community, feel free to comment and incorporate yourself into forum topics and discussions. Our members are happy to help and guide newcomers in any way they can.Report offensive material. If you spot material that might be considered offensive or SPAM, click the "flag" button next to the comment or instructable. The Staff will review and take action if necessary.2.7 I've spotted an offensive ad! What can I do?If you spot an ad that qualifies as offensive, right click (not left click!) on it and choose properties. In Firefox, you can right-click and select "Copy Link Location". Copy the URL and report it to a staff member so they can take immediate action. If possible, it is also good to take snapshots of the page (On your keyboard, press Prt Scrn and paste it on MS paint or another image editing program) then present it to a staff member.2.8 Can I post Instructables in other languages?Of Course! We would be extremely happy to add instructables with languages other than english. If you need help with some words or terms, feel free to ask around on our community! Proper grammar and spelling are compulsory in any language. We have a lot of users who are fluent in many languages including Spanish, German and French.3. Other Instructables Features3.1 How do contests work?There is no complete answer to that question, as different contests have different rules. Usually, a contest follows these steps:1) A staff member usually announces that a new contest is coming, and what the theme will be, so members will start getting ideas2) The Contest is announced in the front page3) A staff member will post an instructable on how to enter the contest, and will show full details about it.4) The Contest is then opened for entries.5) After a specific time, the entry deadline closes and the winners are chosen either by the staff of by community votes (Depends on the contests specific rules) and are announced.There are two kinds of contests:- Regular contests are the ones that last a month. These contests also set the month's specific theme. These contests are usually sponsored by a company that is related to the theme. For this reason, prizes almost always come from the companies themselves. Regular contest feature more expensive prizes.- Speed contests are those that only last a predefined time. They are called speed contests, because users have to submit their entries before a close deadline. Since they last such a short time, there are usually more than one speed contest can be held in one same month. In some rare occasions, there can be more than one active Speed Contest at a time. Speed contests usually have more and less expensive prizes than regular contests.3.2 Are contests decided by the staff or the community?It depends on the Contest's specific rules. When an Instructable is chosen by the community, the winners may have multiple categories, such as best rated, most viewed, most votes and others.When the staff decides the winners, they usually take the community's reaction to it as a factor in choosing the winners.3.3 What is Burning Questions?Burning Questions is a regular event in Instructables, where the staff (usually Noahw since he manages it) posts a list of Wanted Instructables that haven't been made.Users submit their entries and the best instructable that answers a question on the list wins a prize. Since there are so many prizes (One for each question), Burning Question Prizes are less expensive, so there can be more prizes.(Originally, the prize was an Instructables Shirt, but as the community grew, more instructables were requested, and the prizes were getting more expensive, so now, the prize is usually a Prize Pack consisting of various Instructables Merchandise)When a winner is chosen, the staff will send him/her a Private Message telling them how to claim their prize.The staff publishes a new round every now and then (currently, we should be expecting Round 5.)Rules:Although the rules are posted in the same posts that the questions are announced, these rules are important, and if not followed, an entry wont qualify: - The Instructable must have pictures in every step. These pictures must be related to the instructable. - The Instructable must be of good quality. It must have proper grammar and steps must be clearly understandable and detailed - The title must be the same as the question, or else it wont be accepted. If the question is how to fold a shirt, the Instructable's title must be exactly that.3.4 Why is Burning Questions Held?Burning Questions has 2 purposes:Getting people to create Instructables wanted amongst the communityImproving the site's "googleabilty". Since many questions start with How to...., it helps the site appear more prominently amongst search engines like Google.3.5 If Burning Questions is chosen by the staff, then why does it have a voting option for the Instructables?Burning Questions winners are chosen by the staff. The voting option is available because Burning Questions has been implemented into the new Contest Section, because of various reasons.Although it is the staff who choose the winners, the community's response to the instructables is also a factor in the decision. 3.6 If I submit 2 answers to Burning Questions, and they both win, do I get 2 Prize Packs?No, if you answer 2 questions in one Burning Questions Contest, the staff will send you a surprise extra gift along with your Prize Pack.3.7 What regions are eligible to participate in contests?Some contest are open to any country, while sadly others are not available for some countries. Take your time and carefully read the rules and details of contests so you can save time or make arrangements.3.8 How can my Instructable get more views?The main thing you can do to get more views is to make something interesting and likable.If you want more views, try posting a forum topic so people can learn about it. Instructables with good and clear steps might even be featured on the Front page- the most trafficked part of Instructables.com3.9 How are Instructables featured? Members who have shown to be very helpful inside our community are handpicked by the Instructables staff and are given the ability to feature an instructable is they consider it meets the criteria for Featuring. As Instructables are featured they appear on the homepage, the most trafficked part of the site. 3.10 What does an Instructable need to be featured?It needs to be good - clear, easily-read Instructions, plenty of useful photos, in focus and probably using your camera's Macro Function (Click here for additional info on using the macro setting) , and additional notes on the images to explain extra points.You should use full and proper language - capitalize sentences, check your spellings and don't use sms-speak. (cuz-because). English isn't compulsory, but correct grammar and spelling are.If it is original idea, a novel approach or an enjoyable read, with carefully-arranged images, then it is more likely to be featured.3.11 How can I be selected to be able to feature?If you produce consistently-good Instructables, and especially if you take an active, useful part in the community, you may be approached by Eric ( ewilhelm ) to join the team. There is no set number of members of the team, but new members are not often invited.4. Miscellaneous4.1 Is it possible to intern at Instructables?-Check regularly at our We're hiring page for more info. Instructables member TimAnderson is also running an internship program documenting Heirloom Technologies 4.2 What is the Community Section?The Community Section contains the Forums:You can choose to either view topics by category or View All in an option at the top of the pageGeneral Forums - General Discussions of DIY. You can talk about anything, not just DIYMarketPlace - Forums for job offers, Internships, Kit sales and other sale sin generalHelp - Ask for help, report a bug, or just give your feedback on Instructables4.3 What is the Marketplace?The MarketPlace is a special part of the forums dedicated to bussiness like Job offers, Interships, Kit sales, and other sales in general.You can sell your stuff, or buy someone else's. This section is still fairly new, so some changes might still happen.5. Current events and Glitches5.1 I just rated an Instructable, but it says that it hasn't been rated yet!The current rating system is fairly new. Before, the rating system was simply the option to give it a plus, or a minus.Our new Rating System is based on the one described hereThe new rating system, consists of the ability to give it a rating from a scale of 0.0 to 5.0. This system is represented by a line of stars. You may also give ratings like 3.5 and 2.5.This new system is not yet complete, and there are a few bugs to work out. Currently when you rate something, it is queued to be processed during Instructables' overnight Bayesian rating algorithm-run and does not update immediately.Until it is complete, you might notice somethings, like for example, that most Instructables will have a rating lower than 4.5.2 I just saw a comment that says it was posted -xx minutes ago! What should I do?This is a small glitch we are currently experiencing. The staff is aware of this, so please, do not report this as a bug or make a forum topic about it. It is nothing serious and out staff are working to fix it. Instructables runs on a couple of servers. Sometimes, the serves receive different information, and when they each compare their information, they might get confused and say that the post was made at a time that is not possible.The following people have contributed to this FAQ:* Kiteman* NachoMahma* Brennn10ewilhelmThanks for your help!I hope this Section has helped answer any questions you might have.Have a question that should appear here?

I would like to make a simple machine that allows me to roll newspaper logs tightly?

You know those log making machines you can get that let you make your own logs? Well I have seen some amazing furniture made with very tightly rolled newsapers that is so strong that when knocked together it sounds like metal bars. The machine would need to have 3 rollers and a handle for turning the top roller. the loosely rolled newspaper would sit on another 2 rollers and be rolled like a giant hand-rolled cigarette until it was tightly packed into a rod. I wondered if there was some way of either making this from scratch or improvising something? Thanks.

Why isn't plastic used in the construction of houses? Answered

If plastic can be customize to our needs, why can't plastic be customized to be non flammable, UV resistant, non toxic and thermally insulated to be used in house and bulding constructions? Petroleum based plastics are non biodegradable and would last for hundreds of years. Any reason why we do not see more houses built with this versatile product?

constructing an a-frame, lean-to roof on a garage

I started framing a lean-to, a-frame roof like a deck (with an a-frame "header" and three joist hangers). The joists are angled at about a 45-degree angle and are perpendicular to the garage (on which I hung the header). There will be two 4x4 posts at the end of the 10'x10' roof. When I looked for advice about this framing style, I found nothing. Is this going to be stable? I designed the roof this way because I have 6' reclaimed cedar fence panels that will run down the roof like shingles. Thanks for your help.

need help with LARP weapon design and construction

Hi crafters.  I'm in need of help with constructing a larp weapon, fighting fan, that could open up with a press of a button or pull of a lever N close itself upon releasing it. could any help me with the design of the mechanics n gear system I could use to make it work? It should not be of electronic nature though. Here I attached a drawing of how the weapon should roughly looks like . i'm thinking of using rounded edge aluminium flat bars(looks like flat metal ruler) as the bone for the 'blades'. Really appreciate the help.

Math formula(e) needed: tesseract model construction?

Although I CAN do this without the math formula(e) to figure it all out, I would like to have it for a quicker method of figuring out size, etc. so I didn't have to use up so much material in guessing. I would like to construct the tesseract I have pictured here, using rigid clear plastic sheets or panels.   Given a said size for the "inner cube" say 2 inches (approx. 5 cm or about 51 mm) what formula(e) must I use to calculate the panels' dimensions to connect to the larger cube (knowing full well this will depend on the size of the larger cube....say approx. 4 inches across (about 10 cm or 102 mm)? The reason I'd like the formula(e) is that I may need to increase the size of the center cube by an inch or so, and this would allow me to do so without having to go through the "trial and error" thing so many times. I would, of course, want the center cube to be "centered", if possible or shall I say as close as possible. Thanks....

Looking for craft projects for 6 to 10 yr old craft coop. Something that is cool, quick and super fun!

These kids are all over the place.  Seriously there are ten of them both boys and girls.  Other than my two who are used to using materials independently they ask for a lot of help.  Also things that I think will keep them busy for a while they just blow through to be finished without really enjoying or experimenting with materials.  I am looking for construction projects, textile projects, simple machines, anything to keep these guys busy for the two hours they are with me.  You guys will be saving my sanity!!

Can an existing home be eligible for LEED Certification?

My home was built in the early 80's and I've made several environmentally-inspired improvements since I bought it - compost, rainwater harvesting, Energy-Star Appliances, insulatiion, low VOC paint and a 47 panel solar PV system. I've been looking on the Green Building Council's website to see, but all I can find is info on new construction. All I really wanted to do is see if there was a list of possible improvements that can be made on existing residential homes (and possibly the point rating) so I could know if I'm even in the ballpark to meet the LEED certification requirements. I checked into this a few years ago, but with this new 2009 LEED v3.0 it looks like they dropped anything to do with existing residential homes, or maybe I'm just not looking in the right place. So, has anybody else looked into this? Is anybody here familiar with where I can find this information? I want to see what it's like before I register and get inspected so I can tell whether or not it is worth the effort right now.

How to build a verneuil furnace for synthesizing corundum?

Aside form the few demonstration pictures I've found and a hand drawn sketch of the original furnace I can't seem to find any technical information on the design. Anyone have any ideas on how I could do this? http://en.wikipedia.org/wiki/Verneuil_process http://gemologyproject.com/wiki/images/thumb/e/ed/Verneuil.png/300px-Verneuil.png

Drones, not just for spying

So with the advance of 3d printing, arduino firmware, Raspberry pi, and the general open source approach to making things in the last 15 or so years, it's really not that surprising that drones have become as wide spread as they are. Those not interested in drones view them mostly as either a hobby or a potential threat to their privacy, but I had an idea the other day that might push them into better prominence.   What if drones could be used for construction and basic maintenance?  What if a quad copter was the thing that was wiping down the windows of a skyscraper?  Or messing with dangerous high power electrical lines.... Things that are both tedious because they have to be done over and over again, and that are moderately dangerous for a human being to perform.  Why can't a drone be used for some of that, and can one be designed around those constraints?  This is how a hobby user could make innovations that might curtail some of legal and general paranoia surrounding drones.  This is all well and good, but let's take this a step further: Drones are a necessary part of human exploration.  People talk about putting humans on Mars.  Human beings require inputs. Food, shelter, air.... those sorta things.  If there's a problem with one of those things on Mars, there has to be a way to fix that, and it's probably best if it's something that's established before those humans get there.  Drones could be used to do a variety of tasks, and possibly even establish small caches of water or maybe even limited quantities of iron. Maybe even something like a 3d printed iron shelter.... (Induction heating works by pulsing a electromagnetic coil with high frequency electricity, which can be used to melt magnetic metals with high degrees of efficiency. This could be used to make low grade steel on mars, but if time and scarcity of resources aren't constraints... it would work.) Anyway... I was just sort thinking about this stuff. Let me know what y'all think

acceptable angle of deflection for temporary support

Hi, I am in no way an engineer.  I'm trying to figure out what is an acceptable angle of deflection for a combination frame and hammock support.  I'm thinking of using the the 80/20 t-slot beams.  I want something that is portable, easily assembled/disassembled for moving, and lightweight.  I'm go to make a box in our garden to protect our plants and when the corn is big enough, move the box around to make a hammock support(chicken wire around the bottom part to keep the critters out).  It's basically a box 6 feet wide, 8 feet long and about 6 1/2 feet high. 4 beams to make a rectangle on the bottom, 4 uprights(1 in each corner), and another 4 beams on the top to make it more rigid.  Chicken wire will keep the pests out but let me in to relax until the corn is too high and I move the frame.  :)  I'll put the hammock diagonally from pole to pole; total weight with me and the hammock is about 250 pounds.  It will be anchored to the 2 uprights with 300lb chain at each end. Using the angle of deflection calculator from 8020.net, I found some beams that had 5mm deflection with 150lbs of dead weight in the center of the 6 foot span.  I thought that even if I anchored the hammock to the center of the 6 foot span, that would be 300 pounds, more than the 250 max the hammock and I will be.  And anchored in the center of the beam is the worst case scenario since I'll be anchored to the corners. But is that an acceptable amount of give in the beam?  It's not meant to be permanent.  I won't be in it more than 2 or 3 hours tops. Thanks!
