Hi guys,

Quick question, my dads buddy has a Bridgeport j head mill with r8 collet, in his sign shop that no one there has a clue to to run.

Right now it has a collet stuck in the head. It is my understanding that all I need to do is loosen the drawbar and the collet should come out. Is this the case or do I need to remove the nose peice and losen something else also? Do I just need to give the drawbar a couple of smacks with a hammer to loosen the collet?

Sorry this is a total newb Bridgeport question, and I know someone on here will know.

Thanks

Loosen the drawbar a couple of turns, then tap the drawbar with a plastic hammer. The collet should loosen, then unscrew the drawbar while holding a hand under the collet until it drops out.

Perfect thanks guys, I thought that was what I needed to do. I just didn't want to hit it if there was another bolt holding it in.

I welded a socket to the base of a cheap ass plastic tipped hammer so I have both tools right there. losen, flip tool and whack.

Even better, I bought a Craftsman double box end wrench in 3/4" and 7/8", which are the sizes for the drawbar, and 1/2" T nut sets, then drilled and tapped the wrench for a little brass puck. Use the puck to smack drawbar.

better yet :smokin:

Dan De Vinci is a buddy of mine.... he has one of those little palm impact guns mounted on a bracket up above it. just hit the paddle and it zips it off and on.


works slick!
One shop I worked in had a mill with a pneumatic drawbar that worked off two buttons placed within easy reach. I've been spoiled ever since.

Pneumatic drawbars are something else. A butterfly impact is all most of them are.
