I picked up some 2" copper pipe from the scrappy and it's not perfectly round, I'm looking to make a shotgun condenser so at worst I need to be able to make each end round to get the end caps in (this would make it a difficult build but we'll see how we go).
I've seen videos using adjustable spanners and sockets and nuts to re form the round pipe. Any experiences on which method is most reliable (easier for someone who hasn't done it before)?
Also once round (assuming I can get it fairly close) has anybody made a shotgun condenser and heated the pipe (to expand it) and cooled the cap assembly (to shrink it) to make it easier to assemble?
Thanks.
