Wet snow here, so a great time to play in the shop.
Finished the crank bearings, well sort of the bore is 3/8ths right now, they need to be opened up to 7/16ths. Haven't yet decided how that will happen. Seams odd listing dimensions in fractions but thats how the drawing was made.

Thought the crank was cast iron, wrong, some low carbon cast steel that machines horribly. Tryed several different cutter profiles in HSS and a couple of inserts, nothing gives a great finish.
Roughed it to 1/2, leaving some room if it warps a bit when machining the throw.

Didn't even mill nice.

Free advice is worth exactly what you payed for it.
