My new mini mill arrived with a "free" 100mm quick vice, instead of the promised 80mm version...... Nice!

I tried to fit it lengthways, but the mounting slots are a little wider than the 56mm T slot centres.


No problem...... Lengthen the slots by 1mm or so, & mill 3mm deep recesses in the body to clear the bolt heads.

I`ll take off the fixed jaw, to clamp the body upside down to plunge the recesses........
WHAAT!!!!!
Is
THAT the mating face??????

The vice is surface ground on all it`s exterior surfaces, and angle grinder tickled on the fixed jaw mating face, the most important joint!!!
Any pressure will tilt the jaw outward!

It`s a good job I`ve got a mill, to square up the body end face......... It
will be ok, within it`s limits.
So pleased I didn`t pay £30 or so for it........
Anyone recommend a decent milling vice, to fit 56mm centres?
