Precision PVC saw

I could use a little help. I'm looking for some way to make fairly precise cuts in 6" PVC. ( Don't ask, it's complicated. But not pressurized or anything dangerous. ) I tried a side cutting bit in a drill, it worked but wobbled side to side too much to make decently straight cuts. I'm thinking something like a jigsaw, but much smaller, also right-angle style would be good. I've been checking out this site for awhile now so, FOR THE LOVE OF GOD, I don't want to make one out of an Altoid's box ! :) Any ideas ?

Avoid using PVC

I see a lot of projects that use or re-use different grades of PVC pipe due to its easy use and availability. Free or cheap PVC seems to be a good material choice for those who lack the tools and skills needed for metal or wood work. I suggest that builder rethink this choice. Exposure to PVC is dangerous to your health. Fumes and dust from cutting, drilling and accidental burning or overheating PVC are known to cause cancer.A few points:PVC production is the largest use of chlorine gas in the world.Chlorine production consumes enormous amounts of energy.Chlorine production causes mercury pollution. Hazardous by-products are formed throughout the PVC lifecycle.By-products of PVC production are highly persistent, bioaccumulative, and toxic.PVC is extremely difficult to recycle.PVC is one of the most environmentally hazardous consumer materials ever produced.source: http://www.healthybuilding.net/pvc/ThorntonPVCSummary.htmlDifferent grades of PVC have different melting points, flash and glass temperatures. At 70-80 Degrees C (~150 F), most grades begin to soften and degrade in performance. This should be taken into account when building projects that involve any kind of direct or indirect heat, including hot water, etc.(I've edited this post to contain more useful information)

What is the best way to repair a small leak in a non-pressurized PVC drain pipe?

I have a slow (approximately 10 mL per 10 minute) leak in a PVC drain pipe. Cutting out and repairing the entire section would be extremely annoying, and I'd undoubtedly introduce another leak. Has anyone had success repairing a non-pressurized leak in PVC with caulk, or a specialty product such as http://plast-aid.com/ ? Specifically, could I just fill up the space between the reducing bushing and the coupling shown in the picture?

PVC Art(?) How to make PVC Art that spins and turns from Star to Square.

I saw a "yard decoration" made out of PVC Pipe. Viewed one way it was a Square. Viewed another it was a star (6 sided I think.) So when the wind blew and it spun it was...a star..a square....a star..a square....a star..a square....you get the picture. Well I made one and gave it away. Years later I tried to make another and couldn't do it. All you need are several pieces of pvc pipe and about a dozen elbows (90degree bends). Can anyone help me make this? A picture of one you may have would be helpful. Or a web site ...anything. Thanks Modgod

could 12 strips of pvc angle trim be used to make a light but fairly rigid box frame?

I need to make a prop, the base of which is essentially an open upside down box of around 75cm x 75cm x 75cm. i was going to use a large cardboard box but it needs to be able to pack down as flat as possible for transportation and needs to be able to survive potential rain. i'm thinking i could drill a hole in both faces of each end of 12 strips of pvc angle trim (the stuff used around windows and doors), bolt it all together as a frame and attach corrugated plastic panels as the box faces. do you think the resulting box would be rigid enough to survive a few accidental knocks and kicks without collapsing? i'm not intending to add any load to the box other than a few blocks of carved foam for panel decoration.

glass table? (is this where this goes? :D)

I recently obtained for a fair price a cut piece of glass from goodwill. its rounded slightly at the sides and greatly at the corners. at the widest point it is approximately 52" by 24". its 3/8" thick-its fairly heavy as you could imagine. I mean i can pick it up by myself but its worrying me what to build the actual support out of. I was thinking to have 2 tubes pipes or cylinders at equal distances from the right and left edges-it would be at least 10 inches away from the edge on each side, leaving what, 32 inches in between them? Now my question is whats the cheapest way of doing this. i didnt THINK i would use PVC, but i dont have the slightest clue how much it could support, so idk. Aluminum tubing is cheap for smaller sizes, is that better? Id give a weight estimate but im terrible at estimating things based off my senses so thats a bad idea. Maybe you can get an idea off the dimensions. I can spend at max 15 bucks for PVC or aluminum. oh, and the desk is gonna be around 30 inches tall. so 5 feet is just enough. Also, what would be a good idea to place the cylinders on top of for balance? At this point, all i need to do is keep the glass 30 inches off the ground with ~3 feet of space for me to slide my chair into (although its really not a neccessity because itll be out alot anyway.) with a 15 dollar budget. any sugestions?

My friend and i are making a compressed air engine strong enough to work lawnmowers or better yet, a small car. Does anybody know any equations for calculating torque or RPM's? We are somewhat basing it off of the Airhogs air engine but better. Also, does anybody think making it out of PVC would be a good decision? or aluminum? I don't know if it will make lots of heat since there is no igniting of gases so i think it will be safe to use PVC for a lighter engine so more power can be used for moving. any thing wrong/bad about that?

On the other side I put 3/4 inch PVC to an inch from the bottom of the barrel. The PVC is meant to get used something like a straw in your soda. I have the straws in line to the water pump. The problem I am having is that the pump requires to be primed to work. How can I keep it primed? It would be great if there was a valve that closed when the barrel was near empty. That way the pump would continue to pump the water from the other barrels and never loose its prime. Any ideas here????? Again, these are sealed toped barrels. I cannot open them to put a sump pump at the bottom, not to mention, a sump pump couldn't supply the pressure needed for my sprinklers. Thank you in advance for any advice! ! !

Has anyone used underground piping before to cool a house?

I bought a 110 Victorian home in Middle Georgia and was studying about installing underground piping to help cool the house. Has anyone experimented with 5 inch PVC before underground to cool with? I took a study of temps in the house, attic and crawl-space to see if I pulled air from the crawl space, I could use that cool air to help circulate in the house to assist cooling. I found that the crawl-space was actually as close to the outside temp. It wouldn't help. I then studied using piping to put under ground about 3 feet and use a to-and-from push fans then tie it into the fan-only central heat and air system. I then wonderered if I would cause a positive preasure issue. I haven't tested it yet, but I think the ground temp is about 68 degrees constant if you go at least 3 feet deep! Any comments?

If possible to fashion the rod into a blade of sorts the sand with be dumped (SAM_0120).  I capped the bottom of the staff off with a tin cap screwed into the pole and double wrapped the staff with black electrical tape.  Now what I want to do is try to put a small 15 inch blade inside...again if possible.

How can i make my turtle tanks filter quiet??

Here is the deal, I've got what basically amounts to an indoor fish pond about 2 and a half feet away from my bed. It's got a filter made from a rubbermaid tub that sits on a shelf next to it, water is pumped up from the tank, into the filter, then out the top where it pours down a pair of PVC tubes back into the water, about 3 feet below it. My problem is that when the water splashing in the bottom of the pipes sounds just like someone is peeing, beside my head, all night, every night. it;s a bit of a nuisance. My first thought would be to shorted the distance between the filter and the water level, but i cant fill the tub to the capacity it was meant for(300 gal) without it falling through the floor, and i don't want to have to explain why i dropped 300 gallons of water and turtles on my neighbors bedroom to them or the management. My second thought was to build a stand in the tank for the filter and lower the filter, but there isn't enough room in the tank for that. So, throughts, ideas, anyone?

Heating box

Hi everybody First of all I want to excuse myself if my english is not perfect. I have a project in mind for a while. I work on construction in Canada and using caulking everyday it get hard to use it during winter if we don't have access to put them inside. So I wanted to build a little box with an heating system that could work on a jobsite generator. I'm thinking about a plywood box nothing fancy as long it work. I though about place 10 ABS/PVC tube that fit perfectly the caulking tube with alots of hole in it so the heat can pass throught it. So the caulking tube can be reached right from the top of the box and due to the hole it won't overheat. So that's the idea so far. What heating system should I use for this system(I don't want to spend alot on money). Maybe I'm thinking about  1 or 2 computer fan to make the heat uniform. I'm thinking about a space where I can put my spare glove to get them dry do you have an idea for that ? And finaly I'm open to any suggestion that can get the box even better ! :) Thanks you

Star Wars X-Wing Rogue Squadron Costume

Hello Fellow Instructables Members! I created this costume over the course of 2011.  It is an X-Wing from Star Wars.  My friend and I designed it, and I built it.      The total cost was about $120.00.     The original plan was to make it simply a costume i could mount on the frame of a hiking backpack.  I decided to add in the option of placing it on my bike in order to take of some of the weight.  I had a bit of an issue with the front wheel though.   I can only make it balance when i am strapped into the backpack and sitting on the seat.  I should have thought this one through a little more clearly.  It would seem not everything in life can be "Winged."     The backpack mount is set just where R2-D2 would be.  I used my Dremel and cut a hole out a of a salad bowl.  It is not in the picture due to issues I had with wind conditions at the time and balance.  I'll upload pictures soon.  And yes, you can see out of the cockpit.  Seeing in, well, that's another story. Materials: ~ PVC pipe ~ Spray Paint ~ Hiking Backpack Frame ~ Insulation Foam ~ Red Hot Blue Glue ~ Glue Gun ~ LOTS OF ZIP TIES! Wingspan: 10' Length: 14' Any Questions, please feel free to message me :D Before I put the covering on it here is a test I did :

need ideas on greenhouse

Hi there,I live in Boston, MA and I am looking for some advice on Greenhouse construction for winter gardening only (and vegetables that are appropriate for that as well). I am looking to build a greenhouse that I can put up in the fall and take down in the spring for growing a winter garden. It will have to be able to be taken apart into its components and stored in a shed in summer months since my family has no need for it then. Due to the fact that it will be used in the winter, it will have to be highly insulated and have a heat sink that will be able to help maintain a constant growing temperature for the plants inside. Ideally I would like to avoid expending much energy heating the greenhouse. I am, of course, also doing this on a budget. Here is what I have come up with so far. 1. I will use triple-wall or 5 wall polycarbonate panels for the walls of the greenhouse2. I have found a few insulating products that look like they could be useful3. I am thinking of using a solar collector water heater as part of the heat sink- easy to construct on my own : https://www.instructables.com/id/Solar-Thermal-Water-Heater-For-Less-Than-Five-Doll/ that could circulate hot water into the heat sink4. I am learning about heat sinks and thinking that I want to use the simplest design and organic materials (mud, rocks, or water) to hold the heat during the day and release it at night.5. The greenhouse footprint can’t be larger than 8’ x 10’ 6. I prefer the simplest construction that meets my needs (and the easiest to put up and take down)Questions that I have:1. What are the possibilities for using compost as a source of heat?2. What about a PVC frame?3. How would I circulate hot water through the heat sink?4. What are methods to reduce daily management of the project?5. Types of hinges to use?6. What type of material should I place the greenhouse on?- it will be sited on the concrete area around our swimming pool and I don’t know what sort of insulation is necessary after that. I had the idea of wood pallets with insulation inside them but that may not be enough at all.7. Any ideas of ways to re-use materials to do this cheaply and reduce waste?8. Any suggestions on the optimal shape of the greenhouse roof/sides to increase heat retention and circulation of warmer air.9. Any suggestions of retailers that might have the materials that I am looking for.Some links that have been useful so far:http://attra.ncat.org/attra-pub/solar-gh.html#storagehttp://growerssupply.com/farm/supplies/cat1;gs1_greenhouse_building_materials;gs1_corrugated_sheets_panels.html
