This one has been nagging me for a week or so. I gotta ask - why a hole saw over a fly cutter? I see the results look good and that speaks for itself. Even chucking it up on the lathe and boring it was an option.Thanks much, so no big issues with binding I take it.
Rudy, my Consigliere? He's the best!
A dirty picture for you Ray.

You took "down and dirty" and made it work nicely. What did you lube it with? The hole saw arbors I have use drive pins so the cutter floats loosely on the threaded arbor and chatters and walks. I suppose that's the difference, having a good solid mount of the saw to the arbor?
What RPM did you use? Hole size cut?
Well done by the way.
^^^ Edge bevel by hand?
How the heck do distributors justify their prices?
I'm looking at a Ringspann FZ 6202 PP one way bearing, 29.39 euros on their site which is US$35.50:

I talked to the N. American distributor and they have stock but don't sell direct, here we go.

It gets better. One distributor here in Toronto (Wajax) quoted C$348.54 (US$276.26) and another (Canadian Bearings) said C$462.33 (US$366.45).
Bend over Rover!
Not game to try the $6 china option.......LOLA huge thank you to Joachim Ruess who got me one of these in Germany and is sending it over.
We are all part of an awsome community, thanks again Joachim!
Terry, I had read that the one way bearings were troublesome with the fluctuating power loads that a single cylinder engine produces with each revolution, so i didnt even try one.
I built a 50mm Dia multiplate clutch pack, i think it had 5 friction plates all up. Never had any issues with it. Belleville spring clamped it together. released with a lever. Friction lining was same as used in torque converter lock-up clutches.
Easy to start engine with it released, slowly moving lever to engage clutch got the flywheel spinning with the engine. End of a run throttle back and disengage clutch at the same time. Apply brake and do another run within mere seconds!
Terry, sitting here pondering alternative solutions while waiting for dinner.
Have you considered using a collet with flex cable with a shear pin at the flywheel end?
