My next door neighbor lent me his PVC pipe bender and then he left for the summer, so I don't have any instrutions. To use it you wrap this blanket thing around the pipe and plug it in. I am using it on 4" PVC pipe I am using as a drain. Do these work? If so, how do you use them? I tried to use it, but the pipe just collapsed where I melted it.

Something that powerful, mechanical and technical should have a name and model number on it.
Do a GOOGLE SEARCH for the manufacturer and call them for further instructions.

The first thing you should know is that bending pipes for drains is not permitted under most codes. Other than that, you insert the pipe, turn it on, and when the pipe is at the proper temperature you will be able to bend it. Unfortunately, without a mandrel to stabilize the pipe while bending, it probably will collapse during the process.

why not glue on a 90 or 45 degree fitting??????? Seems like more work than its worth

powerful, mechanical and technical? It is just a long box with a heating coil inside and holes at each end.

Reminds me of the first time I ever saw someone bending PVC. An electrician was bending some offsets in 1" PVC conduit with a device costing thousands of dollars. He stuck it in the tailpipe of his Chevy truck. Yep - that truck sure was powerful, mechanical and technical. Wheelchair's advice is worthwhile though. The manufactures website might have some practical suggestions. Bending warm PVC can be like bending a wet noodle.

LOL. To a novice, it is a powerful, mechanical and technical piece of equipment.
Kinda like a commerical flushvalve in a service station washroom. You have a mechanic who can tear down a gas engine and restore it in one/two days, but is afraid to touch a chromed flush valve on the toilet.

The low tech version is a plumber's torch and a can of MAPP gas. I had a friend who was a consumate DIY'er. Never called any professional if there was a chance he could cobble something together himself. He installed the plumbing in his new house. He used PVC and almost ever piece of pipe had scorch marks on it from his heating and bending the pipe to fit.

GreenLee Tools makes one

I have such a tool, and it is controlled by thyristor or transistor inverter-controllers. Today, AC synchronous servomotors with permanent magnet excitation occupy a larger market segment than asynchronous servomotors. This is due to the characteristics of the motors. They are installed on industrial pipe benders. I ordered a conduit bender hire [www.lakeside-hire.co.uk] service to install a couple of tubes near the back door. Almost nothing difficult in the work of the master did not see, you can ask them for these services or ask how best to do.
