i put this here since i figured it was not basic tech.

how many of u know how to or actually use this method for making ex pipes.
ive seen it done before by my uncle who has taught me alot of metal working,machine and fabrication skills.but i never did learn how to use this method to bend tubing, and its something i would really like to learn as its not done much anymore with mandrel bent tubing so cheap.

how long does it take to get this dow.
how hard is it to actually do this
any specific type of sand that needs to be used
etc etc etc
thanks guys

edit
just noticed the tools section and im thinking maybe i should have posted this there, if so could somone move it for me thanks
