1/16 Bucyrus-Monighan Walking Dragline

Eef, I want to get these done. I want to move on to other things on the boom. Pretty boring on the milling operation. It takes 9min.ea to drill the 6 holes and pocket the spokes for the 24pcs. This evening I'm going to program the other side.Probably take close to 15min. each. I could probably go faster but risk breaking my 3/32''carbide endmill. I still need 6 more sheaves that are different size.

Lorenzo, I made each one on my lathe manually:bore,groove,part off, face to thickness.

Oh, very time consuming and boring work. I don't really like those kind of work.
But never the less they look like if they are done by cnc. Keep up the good work.

Finally got this set done. This is enough to reeve the boom but I still need a a couple smaller to run down to the boom hoist.
