Re: Lapping flywheel to crank taper?

[rudderless]

Well, the bell end of the taper is more elastic, at least on a typical wheel.

I used to wonder why motors did not use the square drive like on bicycle cranks.

I lap everything now. I wished I fit the wheel on my Hurricane 10…

I use the course compound as I feel the increased surface roughness lets the surfaces smash, or fit together better.
