Thanks Jim!  :thumbup:

I'd completely forgotten this, intended project.......  :doh:

A VERY net trick there John. If I wore one I'd take my hat off to you  :ddb:
AussieJimG:
It's one of those questions: "what do you do when you have broken all your 1mm drills, can't finish the job and the shops are shut"?

Answer: make the drilling device that you have been intending to make for ages.

Obvious really. Who would make it BEFORE starting the job?

It took about an hour including the time taken to google the Dremel chuck thread size.

Since you're holding yours in a chuck, Jim, seems like that version will work in the drill press, as well.
AussieJimG:
No, it won't work in a drill press because you advance it by turning the bit with the thread. This one only works in the lathe.

There is another type similar to the quill in a milling machine with a ball race for you to hold and move the chuck up and down. I was actually looking for that one when I came across this much simpler one the blew me away with the ingenuity.

If you find the other one, let me  know because it could be useful when small drills needing high speed are used.
