I just bought at auction a Storm Vulcan 901 Tappet grinder, I know nothing about it, anybody ever used one? 

set my grinder with a new lift so the radius is as close as possible. have ground som damaged lifters and the finish shows a change, this is after.020, so I do not try to salvage 15 to 20%.
I am very envious of the machine you found ,majer  cam grinder hear does not have a tool like you do
