Hi everyone, I just started machining my 1/4 scale Gade hit and miss engine From the casting set from Martin Model and Pattern. The castings look really nice-great detail. Here are some pictures of the flywheel machining. 1 -Drilling and reaming the crankshaft hole to 5/16". 2 -Facing the hub and the edge of the flywheel. 3 -Cutting the keyway with a keyway broach (using my mill-drill for a press) 4 -Mounting the flywheel on a 5/16" tapered mandrel and machining the o.d. and face. This is my first motor from castings, so I am being really careful. I don't want to have to replace any! That's it for today. I will keep posting as the build progresses.
