This is submission for my new 0.75 motors in homemade casting

first I'm make connecting rod :

 And now the crankcases for made 2strokes or 4strokes motor (same crankcase) :

Also it's the same crankcase for right or left, I'm think for 4stroke I will use syncro pulley and syncro belt for drive valves
 

Thanks Denis                                France near Paris

All inside crankcase metal machining are doing in one time

You can see a female edge on the left crankcase and a male edge on the right crankcase for good centre


For be sure than cylinder will be perpendicular with the crankshaft I made a special lathe's tool . A pin is inside the ball bearing

Crankcases ready
