Even without the hole, the principal is the same, you need to drive a wedge between the top of the chuck and the bottom of the quill, which will eject a Morse taper.
Two wedges are better than one so you do not exert to much sideways pressure on the quill.

Ye not sure I can be bothered

New keyless chuck are not cheap

They are cheaper than a chainsaw, but dearer than a loaf of bread. Keyless chucks are brilliant if you are prone to losing the chuck key, if not buy a keyed chuck they are cheaper:funny:

If you are talking about a chuck key then use a magnet to keep it in the same place attached to the machine, but make sure you don't keep it in the chuck:thumbs:

I have mentioned this before however repetition can be good. Go to repair shops and request U/S magnetrons they have efficient large rare earth magnets place one on every machine that requires a special tool. The drill press convenience will give certainty . Each Magnetron has two magnets. Makes life easier for me. The real advantages of a drill press having the through hole in the quill and using a draw bar are now very apparent in the conversations.

Kind regards Peter.:thumbs:

Probably cheaper and quicker to buy rare earth magnets from China.
