Between my shop and my cousin's shop 5 minutes away that I can use anytime,we are pretty well equiped,he has the big stuff,I have the little stuff.......
drill press-----3
arc welder---3
mig welder
broach
large bridgeport mill
lathe 18x84
large bead blast cabinet----2
out door sand blaster----2
complete vavle grinder machine-setup---2
machine to re-surface heads and other large similar objects
large electric band saw for cutting metal
12 ton press
large assorted of tools,most made for a specific job
4 air compressors,3 electric,one gas portable........
I'd guess the mig welder/mill/lathe get the most use....
and the knowledge to use most of the stuff without inflicting serouis injury to the operater or any innocent bystanders
