[How do I?] Drill Hole In Stub Arbor....?

[EmilioG]

I just scored a new Jacobs USA 14n and it has a stubby 1/2" arbor with no shoulder for wedges.
I need to drill a hole in the arbor to press fit a pin to then use the wedges.
How can I hold down the chuck and arbor to drill a hole near the chucks body end where the arbor is?

or should I drill a hole through the body and punch or press out the arbor? (it has no body through hole)
must be an early USA 14n.

Thanks

Chuck a piece of round stock in your lathe then tighten the drill chuck on the round stock. You can then drill the arbor. Hope this is clear.

Jacobs does say on the web sight on removing stubborn chucks to drill a hole through the body. And it works quite well.

Another way that I have used on straight shank is chuck the shank in the 3 jaw chuck on my lathe close enough to use the wedges.

That;s a good idea! Thanks. Never thought of that. Thanks
