Hi all,
I have a couple of issues with the drawbar on my Bridgeport m-head
1) the topmost portion is bent, which causes it to bind in the spindle when the left hand nut is screwed on tight
2) it's too short to reach the threads on my mt2 collets, by about a half-inch or so
I'd like to disassemble it, but I'm having trouble getting the top hex nut off. I understand it's supposed to pull straight off after the set screw is removed, but it's stuck pretty tight. I've tried soaking in evaporust, oil, and a torch, but can't get the thing to budge. There's nothing to pull on with a puller, that I can see, and the gap between the hex portion and the left hand nut is too small anyway. Does anyone have any tips? I'm getting close to just cutting it off, grabbing the LH nut and remaking the drawbar...
I'm not sure why it's too short, either... The threads match on the drawbar and the import collets (3/8-16). Is it possible this drawbar is for B&S#7 collets? Did they also use 3/8-16 threads? Or the other, rarer Bridgeport collets (I forget their designation).
Thanks in advance,
Lee
