[AT] More on torches

Greg:
I have 2 plasma cutter, both Thermal Dynamics brand.  In my estimation, 
the best made.  I have done both things with them you have noted.  It is 
difficult to keep from cutting the shaft when trying to cut the bearing 
race.  The problem with that oddball job is that when the torch is 
running without anything to cut, it wears greatly on the tip.  Those 
tips are from $8 to 12 each, and the electrode as expensive too.  It 
runs into money quickly.   I do like it for cutting rusty steel stock.  
I have a lot of old oil tank steel  that I use to cover truck and 
trailer beds.   With a straightedge, I can cut the steel straight enough 
to butt weld.  I cannot do that with a torch...
