Aeromarine coupling for NOVA 91DD

[Shane Bastick]

Does aeromarine make a engine coupling 8mm without shoulder to fit the Nova 91DD engine, unlike the cmb versions that have a shoulder to inset into the flywheel

thanks in advance

Contact Al Hobbs on here when he returns from the Worlds, I'm sure he's got them and they are the best I've ever used.

Thanks, John

A simple fix is to just grind off the shoulder.

I always drill the flywheel with a drill bit that is about 0.400" to about 0.150" depth.

I think I like Marks approach better. Chucking up in a Lathe might be a little cleaner using a boring bar.
