LeadHead........What I remember was from my shop class in 1956. I would think the compound directly on the wood dowel.
I don't think you would have a really defined edge using a rag..Practice,practice ,practice..The process looks so precise
you couldn't use a hand held drill.It has to be perpendicular to your metal..Nowadays they probably use a machine like a plasma table with a motor mounted in place of the torch and their abrasive pad on the motor..programed with software the pad would extend,swirl,retract . move a bit and do it again.Remember tho ,on "The Spirit of St. Louis", no CNC ? whatever you call it..
