[TheForge] Fwd: cutting off copper ferrules?

[Michael Horgan]

Coming in late to this, but I was on vacation, 
camping. Looks like you've got your ferrules cut 
off now, but for copper if you use whole milk as 
a cutting fluid, it  doesn't gall up on the 
cutter.  As others said a slight back rake on the 
cutting edge keeps it from grabbing.
