There is a better way - IMO. I took my wheel and cut the center out of it. I then made an adapter out of 1/4" thick aluminum with a step in it the thickness of the wheel ( around 1/16" ). Drilled and taped the edges ( 6-32 ) in 3 spots for set screws. Also made 3 adaptors ( above wheel )to take 3 different sizes of dampener bolts to handle any engine I may be working on. With the proper adaptor, I use the dampener bolt ( may have to washer up some ) and bolt the center section up solid to the crank snout. I can then rotate my wheel as needed and lock it down with the 3 set screws. Done! I can rotate the engine in ether direction with no slop. I love dis country!
