Hello once again. Based upon past experience i am sure there is somebody who can help me with the problem i am facing with assembling the flywheel/crankshaft. I have successfuly made both halves of the flywheel assemblies consisting of steel inner and bronze outter. All holes are reamed to size and square with axis and the halves run true on a madrel. The problem that i am facing is getting a mechanically strong joint between the crankshaft ends , the crank pin, with the steel centre. The design seems to rely upon the screw deflecting tne steel inner thus gripping the ends and pin. I feel the design is mechanically flawed. The srew just cannot exert enough force to get sufficient deflection to effect a mechanically secure joint. Have others found this probem, if so what was your solution?
I am considering using some sort of key betwen the crank ends and the bore in the steel centre. Perhaps not a square key but a small set screw tapped into the joint line. I have also considered using some kind of super glue or Loctite product.
Any suggestions would be most welcomed.
Regards
Trevorc
