PVC is one of the most toxic products ever created - seems no-one here realizes this - PVC is NOT something to play around with - esp not for indoors! Google it!

I've been trying to find a bag to easily transport a project made out of PVC after it's be disassembled. The longest piece is 5ft. My first thought was one of the bags used for the colorguard flags, but those don't fit a whole lot. There has to be someone on here that's run into this problem before. Maybe someone has figured out a good way to carry PVC that isn't a bag? Any ideas?

I was looking at all the excellent instructables about marshmallow guns, but I have a concern. I'm Canadian, and it seems to me that the inner diameters of 1/2" PVC pipe in the US is larger than 1/2" PVC in Canada. So, could someone in the know please straighten this out? Is there a difference or not? If so, what would be the appropriate substitute size? Thanks to all.

The PVC soil pipe under our bathroom has developed a slow leak. This pipe is inaccessible as it runs under a platform that lifts the bathroom above the concrete floor of our enclosed garage. It may be a crack in the pipe (unlikely) or a connection between the tub and the main pipe (more likely). Is there a liquid sealant that I can pour into the tub drain that will seal this obviously small opening?

I recently learned about Con-Tact brand chalkboard contact paper, which I think it really cool! You can cover a surface in it and write with chalk. I thought it would be cool to use a laser cutter to cut the paper into shapes, letters, etc. and put it on the walls. Alas, after contacting the manufacturer, it turns out to be made of PVC (vinyl). Laser cutting PVC produces chlorine gas, which besides being toxic, is also highly corrosive and bad for the laser cutter. Anyone know of an alternative that's not made of vinyl or PVC? It doesn't need to be big like contact paper, and it doesn't need to be chalkboard-like either (for chalkboard stuff there's paint), but I'm most interested in some kind of material I can cut into shapes and stick onto walls and other things. Thanks for any ideas!

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 ?

We needed 80 feet of 3/4" PVC from the local hardware store. Since it's pretty much impossible to park near it and the nearest available car was a couple miles away anyway we decided to carry it by bike. All we used was a couple pieces of inner tube and Brian's Xtracycle. I bet I could've pulled this off on another bike I've recently adopted, but we wanted to be safe. Speaking of safe, this rode pretty well, but the left turns were a little touchy as the front wheel would rub against the PVC. Good thing I was only going a few blocks. Along the way guy in the street told us that that was how the Vietcong would attack them. "They used to strap missiles to bikes! Heheh. Yeah, they kept getting us."

I have ran into a issue with a project that i cannot figure the best solution for. Here is what i am trying to do. Imagine a pvc pipe setup in a ladder configuration. On top of each side of the ladder system an aluminum angle rail runs up and down each side. On top of this rail system is another square pvc piece with ball bearing mounted externally allowing the pvc square to ride up and down the rail. My issue has come from automating the pvc square to move back and forth on the this rail system. I thought of using a dc motor driving it to each end where a switch would be contacted to reverse the motor in the opposite direction. The issue is getting a motor that has enough torque to move the pvc square with about 10lbs on top of it maybe less and to do this a fairly slow motion. I had thought of maybe using a cheap 540 rc car motor, but this is where my ? comes in. How do i drive the square with the motor with out getting overally complicated. Would i be able to adjust the speed of the motor with a potentiometer? If so would i be able to keep the torque or would that reduce too? Finally is there another option that would be simplier to exectue?

I'm trying to pass a PVC pipe through a plastic lid into a plastic box without leaking water from the pipe or the box. The water in the pipe will be pressurized, while the water in the box will be splashed. A small leak isn't a big deal. Unfortunately, this is also a bit of a stress point, though not terribly. See the picture and the diagram below (which is actually not quite right; the pipe on the top won't be that long; it will turn 90 degrees just above the plastic lid. Any suggestions on how to keep it from leaking? Perhaps make the T under the lid flush with the lid and the same for the elbow joint above it, and then make the hole as small as possible? That wouldn't keep all water out though, but it may work for splashes. Any ideas are greatly appreciated!

I fix gym equipment, so I throw away quite a few used treadmill belts. some of them are in good shape but just got too dirty to be useful anymore (friction problems). seems a shame to throw out all that plastic, surely there are some good uses...can anyone think of some? I just installed 8 today and hauled away the old ones. In the past i have screwed them to the bottom edge of garage & bay doors to act as an extra weather seal - helps prevent the cold air from rushing in those air gaps. the belts have a pvc topcoat and textile/woven fiber bottom. I wonder if any recyclers would take them...i hate dumping stuff in landfill. Wasnt sure where to post - resources, free stuff, Green....they would all apply really...

Right now, I am in the process of building a small tethered submarine that is only about 1 foot long. There will be an external light module on it. So far I have a cluster of LEDs and a 9v battery holder that are both waterproof, but I do not have a way of turning the lights on and off that is waterproof. Does anyone have any suggestions on how to waterproof a switch or where to buy a waterproof switch?

I just built a big piston valved spud gun. I can't get it to fire. When I release the pilot valve no air even comes out. The piston is sealing though. I think it might be theres not enough air in it. I charge it using a 1.5 gallon compressor at 100 psi. The chamber is 5 foot of 3 inch tubing. I don't know why no air even comes out of the pilot valve. I know their isn't leaks or none big enough to hear.

Asked by WerdnaN 8 years ago
I have a question for spudgunners and other people who know about PVC. I've heard that PVC becomes bitter at low temperatures, so you shouldn't expose your spudgun to low temperature, but is it okay to leave it out in the cold and then warm it back up for use later? Does that affect the strength of the PVC? I have a problem storing some PVC in an heated environment during the winter.
