I'm sure none of you have ever left the wrench on your Bridgeport drawbar after tightening the collett. In case curiosity gets to any of you as to what happens, it strips the threads.
In my defence I worked the graveyard shift the night before and seeings how it was my last one for a few I didn't lay down and went straight to the shop.
Now all of that said any Ideas on a good way to repair it.

Thanks in advance

Mend it with a new one.
Loads of people sell these and they are only a few $$.
You can get double life ones where when it strips you cut the bad bit off, remove a spacer and you have a second life.

I have repaired them when i have been stuck but to be honest it's not worth the effort unless you are really tight http://bbs.homeshopmachinist.net//biggrin.gif

Welllllll! I have cut of and rethreaded the
end of one at school. Had to aneal it and
re-harden it after threading.
BUT get in the habit of using an OPENEND wrench
to tighten it and you wont let it happen again.

What kind of head? 2J? Do you have a low/high range selector? You might have been OK if you did because you would have just backed out the draw bar in one direction, or tighten it in the other... I'm surpriused you dammaged anything.. On my 2HP 2J head, I can stop the spindle immediatly with the brake handle.. I have't tried stopping it by leaving the wrench on though http://bbs.homeshopmachinist.net//smile.gif

No excuse, buy a new one, consider it a cheap lesson.
It is like leaving a T handle in a lathe chuck.

I',m surprised nobody sells a spring loaded draw bar that would push off a wrench that isn't being held on.. Some of the newer T-bars have a spring.. Same with some of the new drill press keys... Man, they are annoying if you have one though, eh? http://bbs.homeshopmachinist.net//smile.gif
