Porting 004

This is a rough-out tool that I used in the early days. Bought from Goodson as a 'valve seat narrower', but does a pretty good job of boring valve pockets for oversize valves. Pilots on valve grinder mandrel, driven by 1/2" air drill. Bit shown is for different job. I beleive it's called a "Bausfield Tool".
