Got a #19 Super Chuck that has one jaw that will not extend with the other two and is jammed in so the chuck will only retract - open? - half way. The chuck isn't rusted or been beaten on. Any suggestions how to get the thing apart so I can assess the damage, clean and lube the thing? I tried pressing it apart as usual but there was clearly something jammed by the out-of-position jaw.
I'm afraid I can't help much there. I had the jaws fully open on my chuck before pressing off the outer ring. I have only taken apart two of these chucks so I am far from an expert. One of the commentators on this video seemed to be well versed so you might ask him. Other than that you might try contacting a more experienced machinist like Tom Lipton th-cam.com/users/oxtoolcovideos or Steve Summers th-cam.com/users/SteveSummersvideos. As I recall, both of them have videos on repairing chucks Good luck with getting it fixed.
Paul That is going to be a valued addition to your shop ,the press and the chuck. Enjoyed the video. Mike
Mike, Glad you liked it. I enjoyed fixing the chuck as well as building the press. Thanks for the tip on the punch press dies.
Thanks, Mike. And thanks for the tip on the punch press die sets.
Real cool video! It’s great to see how you got to where you were when we came to visit.
Hey, Alex. Great to hear from you. I didn't know you were a subscriber :-)
That was a good cleanup on the chuck. A nice addition to your shop.
Thanks, Harold. I was surprised how easy and well it turned out.
The 18N chuck looks great! You could look up into the spindle bore for a defective collet key, wear and rust before indicating the taper.
Thanks for the tip. I always run my finger up into the taper before installing a collet but I have not really examined it.
do you have a video of you press build?
Yes, it's the one just before this. th-cam.com/video/ZsyOQpWtHe4/w-d-xo.html
