I was already thinking about that!! I will machine a 1-piece pulley that fits my 1/2" motor shaft.
I finished assembling the head today, and have a problem with the variable speed adjustment. When I apply air to the cylinder, the air cylinder runs, and the worm-gear turns; but the shaft/dial/chain does not turn. Do you know if there is suppose to be a drive-pin on the dial-shaft? Something has to be there to drive the dial, and I could not find it. It was getting hot outside this morning, so I stopped at that point. I will look closer tomorrow morning. I bet something is sheared-off. Wish I had a shop with A/C in it. |
