The Ford Barn - View Single Post - Help: Removing swedged weights on Model B crankshaft

I was able to drill all the pins out. I discovered that the pins aim straight to the centerline of the main journal. I thought they were off center a few degrees from a sketch I saw a couple years ago. The pins are about 3/16" in diameter. Once drilled out, Pete's suggestion of using a lead hammer slid the weights enough to allow for grinding.
They are both ready to go to the crankshaft grinder. Thanks guys!

SIDE NOTE: As I was drilling the peened portion of the crankshaft holding the pin in place, the drill bit hit the top of the pin and it started down into the pin a fraction of an inch and the pin started to turn. I put a bit more pressure on it with the Bridgeport and then backed the drill bit out. The pin was stuck to the end of the drill bit and it pulled right out. The angle of the pin through the counterweight and into the crankshaft was easy to determine after that stroke of luck.
Good Day!
