pretty sure I have a spare 1/4-20 spiral point tap. Would be no chore to stick it in an envelope and get it to NJ if you won't mind waiting for the post.

I use a collet on mine and have had no problems at all. Speed is very slow. Tom Lipton has a great little primer on power tapping on the mill. Here's the link:My mill has a variable speed motor so I'll be able to go down very low in RPMs.
I plan on trying a collet first versus a keyless chuck. I 'll have to see what the diameter of the tap is versus what collets I have.
