3 things only? What about facing off flywheels... you can bore out where prop adpter seats against flywheel... turning prop adapters.... tapping and drilling dead center in adapters...turning outside of cyl fins to get a neat look...cutting base of cyl down to get more compression. I am sure there are more. I plan to have a seperate milling device. Maybe a good cross feed milling vise in a good drill press. Any other thoughts....anyone? Thanks Capt,n
