[TheForge] Fw: cutting off copper ferrules?

[David E. Smucker]

Jerry is right, a dull tool works better on copper or soft brass than a 
sharp one.  Also try a positive rake angle on you cut off tool.  Also helps 
to turn a wood or plastic plug and place into the id of the tubing.  (Or you 
might find a wood doll that is just the right size.)  With the plug in 
place -- back into the chuck, then you can hold the other end with the tail 
stock which alows you to use more cutting force.  Use soap or wax as a 
cutting lub.

If you can find copper that isn't dead soft that also helps.

I don't think you have one since you don't do any welding but a plasma 
cutter just might work too.  You would clamp the cutting torch and turn the 
work piece.
