I'd buy a barrel from numrich egun parts and get it fixed.

I'm with you on that one. For $35 and the cost of installing it, it would be worth it.
For all you more experienced home gunsmiths, do you think this would work:
1) Drive the barrel pin out
2) Remove the cylinder
3) Reinstall the crane without the cylinder
4) Make a jig from a block of hardwood or high-density plastic to fit around the front of the frame/crane to clamp it into a vice
5) Apply some Kroil or PB Blaster etc. to the barrel/frame joint
6) Apply some light heat to the frame with a small butane torch and some ice to the barrel
7) Use a pipe wrench on the barrel at the ejector rod lug to remove the old barrel.
8) Put the new barrel back on using the pipe wrench WITH a piece of thick leather wrapped around it at the ejector rod locking lug as padding to protect it from the pipe wrench teeth
9) Re-drill the barrel pin hole with a drill press
10) Re-insert the barrel pin
Think that would work to change the barrel without tweaking the frame?
