What is the major end diameter of the taper? Maybe one of us can find something. As far as a keyway, the taper fit is so good, I think just drilling a shallow hole & putting in a short round button pin to match the adapter groove would suffice.
Thanks, Daniel--that's a good idea.
The major diameter is 1.5"--but it's within an 1/8th of the engine case. The minor diameter is approx. 1.25". The length of the taper measured on the centerline is approx. 1.25". I drew it up in my CAD program and figured it out it's an 11 degree angle.
Chris referred me to an eBay seller that will custom make tapered adapters. His prices range from $25 to $60, so that's not a bad price.
I haven't decided what to put it in, yet, so I don't know what type of coupler I'd need. I'd like to find a Case 446 or 448, or 6XX series, an A/C 620/720, or even a Simplicity 7790.
I may put it into something fun, like a Coot ATV... a guy down near Lost Wages has a bunch of stuff for sale. I'll be down there with work in March, so I plan to stop buy and check out his stash.
The engine only weighs 180 lbs dry, so it's not very heavy--in fact a little lighter than the Mitsi L3E that Pager450 put in his JD400.
