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. Andy |

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 . Bill |

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 :) Ralph. |
