Drill chuck problem

[jimbo51]

I have an ancient drill guide which attaches semi permanently to the drill (my old Black and Decker). Since my 30 year old drill is slowly going bad, I need to move the drill guide. I cannot get the guide shaft off my drill. There is a hole in the middle of the shaft and I have tried putting in a hex key and striking it sharply with a hammer. No joy. Any ideas other than to hit it harder? [attachimg=1]

Does the drill still work?  Try forward and reverse with a rod in that hole. If you have a vise, clamp part of that setup down.

Cheers. Bryan.

Hmm. Is that the fixed drill shaft? I put the attachment on about 25 year ago so the memory of the event is gone.

I also lost the instructions years ago. Maybe all I have to do is remove the chuck from another drill and I am good to go?

I will try the suggestion but I doubt the drill has the torque needed. Usually it requires a sharp blow which is much more instant torque than the drill can manage. Ignore my 2nd post. I was suffering from Christmas light sorting. fatigue.

Any other ideas?

Putting a bar (or hex key) in that hole a giving it a strike is a good idea provided you know whether it is a right or left hand thread. I suspect it is LHT. You could also try giving a short blast of heat near the join just before you strike the bar.

Good luck. Thank you for reminding me about the lights!

Use a pipe about 2' long and slide it over the Allen wrench
This will give you a lot of torque

Remember it is probably reverse threaded, most drill chucks are left hand threaded.
