When I hammered 6" copper barrels into 1/2" PVC stubs, it took me a good 10 minute to get them in.
It's a good idea to sharpen the edges of the copper before-hand, because I noticed that the coppe shaved away the PVC making an excellent fit. However, getting it out is nearly impossible.
Eh, you have to be careful though, or you risk mis-shaping the copper...
