Demon V8

Michael, Awesome work and thank you for posting the setups and details.

Have you considered using a dab of lapping compound to deburr the gear set?

I made a full set for this engine out of brass and they held up okay. I had to pin the bevel gear to the distributor shaft though, as the tiny set screw would slip while running even with Loctite. My water pump gears didn't come out too well.

Cheers!

HI raveney
I did think of putting some past on the gears and see if it smooths them out, they don't need much

I'm thinking there is something like 1/2º of backlash in my 4th axis, its never shown up in anything else I have done in the 4th but gears might be a bit different
I Like your Demon the bell housing looks good too with the extra ribs on it
