Really? I've gone off the idea after a thinking about it.  If/when a bit of swarf finds its way up the tube it'll cause chaos and be difficult to remove

Having a screw-in pointer (or a grubscrew fixing) might give a firmer fixing, Bill. One held by a magnet would have to be a very good fit in its hole to stop it waggling a bit from side to side.

Yes you're quite right.  A screw in one would be my preferred way, but I can see no way to stop the lower taper (the bit with the magnet above) turning.  A clamp with a grub screw might be the answer .

Well I liked the magnet... But I see the points about the swarf and flex.

A good fit would definitely be required!


How about the use of a tommy bar through or into the receiver so you can screw one in still?


Just a thought...




Still wanna make one  :)
