I sorted my pile of drill chucks today, and one of them was a Jacobs
#16 ball bearing super chuck. It seems to be in OK shape, except that,
sadly, its "rear end" is tapered for some sort of small taper, and is
quite torn. I feel like, if I had a proper tool or technique, such as
a proper reamer, I could ream the hole for a bigger Jacobs taper and
get a functional chuck.

So, is there some simple procedure for fixing said chucks? It would be
sad to throw it away.

thanks

I've done that with a reamer that I cut and set up in the mill. You just
have to figure the right dimensions to modify the reamer. They might make
such, I never looked. I just had a bunch of reamers I could afford to
destroy.
