Heat shrink fitting and crankshaft balancing.

madman:
Picclock no thats NOT what I implied. I am not good with computers so i cannot draw you a picture of what I meant, BUT yooure drawing as you made it . Looking direstly at it drilling a hole (and reaming of course for the ground pin) you drill to bissect the small pin with the flywheel or crank half. This creates a Half Moon in each rotationable pressable section (HA hows that for engineering words ) then when you press the pin in place and peen over the HOLES (drilled through crank halves is also OK but not required, Up to youre preferance. peen each end or TIG weld a little blob, Some guys TIG weld the Crank halves and rod Pin. BUT heat and such is better avoided in my opinion.  Just pin the moveable pieces to hold them . They will NOT move Guaranteed and unit is still removable. If you drill Like you drew in youre sketch that weakens everything. Not a Viable Option . Hope this helps., Mike

RichardShute:
What you are saying is that the pin is axial and ends up acting like a key in a key-way. Albeit, made and fitted in situ.

It's a not uncommon way to do it and, as you say, far stronger than a cross pin.
