Got all the timing gears done. I decided to make the primary gear and shaft one integral unit rather than trying to loctite or solder the gear to a shaft. The second and third gears are ganged and soldered together. Then, the fourth gear rides on the crankshaft at 1/4th the speed of the crankshaft. The cam will be attached to the fourth gear, probably with a mechanism which allows for timing adjustments. Chuck |

Very nice. Show the cutter for the gears, I'm assuming a Sir John cutter? Brian |

Just used commercial involute gear cutters. I have a complete set of 40 DP cutters as well as an assortment of 24 DP, 32 DP and 16 DP. I want to try making my own hobb one of these days. Chuck |

I think I've wrestled all the remaining design questions to the ground so the worst part is over. Today I made the back timing gear cover or back cover for the back crankcase cover which is confusing, I know. I've also drilled and tapped the holes. Next, I'll be cutting away a significant part of the back cover and the sides of the ring to look something like this: Chuck |
