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.

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.

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!

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....

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.

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!

Outrigger specs seem a little etchasketch??

Three piece plywood outrigger canoe, current rig has a 16 foot hull consisting of the two outer pieces, and is 22 inches wide. It’s hooked up with a tacking rig, a 14 foot mast, and an 11’-10” boom. Originally, it would total 24 feet with the third middle section, but I’m not building that. With a hull 16' long coupled with a fat 22" width, and a simple tacking rig, am I guna get much speed on this thing? What’s more is that the closest body of water is "Steal house lake" and other various lakes in and around the Killeen, Ft. Hood, Austin (Texas) area, everything’s bigger in Texas, but they're still just lakes, coupled with a 24' monster designed to cut and glide over ocean class behemoths (also why I kicked the 8' mid section that i really, really don’t need in these tiny waters). So what do you think, the plans I’ve got are solid, clear, and decisive, the boat and rig are all drawn up, and I’m about to start the first piece of the hull tomorrow (soon as I get the wood). Should I stick with this 16' by 22" hull, should I add the 8' even though I’m just on a lake (a big one ill grant, but a lake all the same), should I jump for a strip-planked composite, or go somewhere else entirely, what should I do, what should i do?? p.s. Rig also computable with an oceanic lateen, or “Crab-claw” rig, lest that’s what i think it’s called.

Roof deck over synthetic membrane: water intrusion?

Oops, so I posted this in Outdoors before I found Home. Double posting is irritating but it's kind of relevant to both... I'm new to the forums here (long time reader, infrequent poster), if I just committed a major faux pas, gimme a heads up and I'll take one of these down! Anyway, so the back door of my 3rd floor apartment opens on to what amounts to a raised back yard; the only problem is that this "back yard" is the roof of a 2 story addition to the brownstone I live in, and I'd rather not put my foot through a very expensive roof. I've been looking into decking, and right now my plan is a contact-only solid frame all the way around the perimeter of the roof, with a lip extending over the edge of the roof (to supply stability without puncturing the membrane) connecting to the actual frame of the deck which would of course be placed over the top of the brick walls of the building. From there I was going to face the deck with synthetics, probably with struts placed along the horizontal struts of the roof connected to both the upper deck and sub-deck cross bracing (depending on what materials I use/can afford and their relative strength). My hope is to find a way to make the deck in modular pieces that can be removed for when the roof inevitably needs to be resurfaced. So basically it would be large squares (or irregular shapes, whatever) that would sit on top of the struts/cross bracing with the help of a few screws and provide the deck surface. What I'm worried about is water intrusion at the contact points, such as around the edge of the roof and on top of the studs in the middle of the roof. I know synthetics are much more resistant to this type of failure than older materials, but are they impervious? Where do the pros put contacts so water doesn't leak into the floor below? Even if you minimalize it, the deck will have to come into contact with the roof at some point, or you've found some fancy new way of building I'd love to hear about. A few other thoughts are footprint: the building is an 1890 Richmond row house, could this be done with a small enough profile to increase the value of the property without damaging the "drive by" value? (I was picturing an iron railing to keep the project semi period, and this roof actually connects to the big hulking wooden fire escape, so it wouldn't be marring a virgin landscape) Also, do you think any building codes in the country would allow L bracing and big old bolts to hold the structure of the deck together instead of end-nailing the boards? It would make removal for roof work a lot easier. For the corners, would it be better to miter the ends at 45 and run a bolt through the two of them, end nail an L joint or use a thick metal l bracket and a few bolts to hold the joint together? That was kind of an intense post, I'm just looking to shoot the breeze a little bit with anyone who has any thoughts. Everybody always has their perfect way of doing things, on such a big, high pressure job (if this goes south I'd be poor AND homeless!) I want to really chew on the idea a little bit first. Thanks to anyone who actually read this far!

Ever heard of Ceramicrete, MgO cement, Magnesium cement

Has anyone ever worked with MgO cement?  Where can buy it in US? MgO replaces the Ca found in portland cement. MgO cement makes a concrete that will incorporate cellulose and other organics into the crystalline structure. absorbs CO2 instead of generating it, is an order of magnitude stronger than portland, does not require wetting, and cures in minutes. So basically, you can take some burlap or old blanket and paint this stuff on, then fill the void with straw and cement and make super strong, light and thin structures. I have looked for it locally but it does not seem to be available to consumers in the US, probably because of the lack of sheep crap which is the typical source of Mg. It is amazing stuff. This is pretty much the only article I could find about the stuff: http://greenhomebuilding.com/articles/ceramicrete.htm
