New vice jaws

I inherited a Paramo quick release vice from my Dad. The mechanism works well but the jaws had seen better days, noticeably worn. One end had about a millimetre gap when closed.

Old and new vice jaws

Trying to get replacement jaws took a little time because the vice has no markings, except the make. A bit of research uncovered that these vices are now just called WW2 vices and there were a few similar but slightly different designs.

The Vice Works in the UK were helpful and after exchanging some measurements, the nearest stock jaws are Record No. 110. The bolts are a bit snug but the jaws fit nicely.

I measured the positions of the bolt centres as 8mm up from the bottom with spacing of 79.375mm (3-1/8") between. The Record No. 110, is that spacing but 9.1mm up. Luckily there is enough play for that to work.

The original bolts are 5/16"-18. I was pleased that the new jaws arrived threaded M8.
