8.625" OD PVC pipe, available per linear foot. (Tesla coils, workcoil shield for coinshrinking, etc)

Machinist Materials, a shop that sells surplus materials from the machining industry, has a small ebay store. I recently purchased some material lots from them and I came across something enticing on their homepage located here:


They have some 8.625" OD, 7.500" ID PVC pipe. That is .563" wall thickness (9/16") which is pretty beefy. Its 9lbs per linear foot (heavy!) and they are asking $15 per linear foot cut to lengths up to 66", or $60 for an entire length which works out to $10.91 per linear foot. They also have 10.500" diameter, .750" thick end caps made of PVC available for $8 apiece.

I figure this material would be perfect for people wanting to build a medium-large tesla coil secondary, or a coilform for SSTC/VTTC primaries. The material is plenty thick compared to regular PVC piping so you could put screws directly into the ends of the pipe walls. It would probably work well for primary containment of smaller coinshrinkers (with a heavy steel enclosure over it), spark gap enclosure, and other things that require big insulative cylindrical forms.

It's not often you find PVC pipe bigger than 6" diameter at the local hardware store, and it's almost never cheap as you can't buy it per linear foot. I am not sure what projects you guys have out there, but this stuff might be suitable for you and I thought of posting it here in case anyone else is looking for such material.
