Ummm, do not have a mill (yet) and I doubt I would live long enough for my little shaper to gnaw a new vice out of solid!

Besides, you have to realise that this little vice is 'special' as it came with the Adept shaper, which is a dear wee thing in itself!
I will take it to an 'expert' to get it brazed. If I am still not confident with it I might screw it to a plate.
