Mill Vice position

[VicParticipant @vic]

I have a job coming up that ideally needs my mill vice to be accurately angled at 45° to the table. It’s a plain vice without a swivelling base. Anyone have any quick tips on how I might achieve this?

I just put the vice at an angle and clap it down. Usually I can get one stud in the usual place and the other I just use my clamp set for. Put a set square or angle gauge against the fixed jaw and clock that true

If found this image in a good book, although the vice is on it's swivel the scale may not be accurate so I'm clocking it in with an angle gauge and dti, setsquare out of a school geometry set will also do

As Jason B, you can put something with the appropriate angle against the fixed jaw and adjust vice to suit or use trigonometry and a DTI to get your required angle

Thanks Jason, I’ll give that a try.

If you put a DTI on the fixed jaw and set to zero then for 45° an X axis movement should equal the Y axis movement. Eg if you move X 50mm then to get the DTI back to zero should require a 50mm Y axis movement.

If you have a DRO it might have an angle setting facility.

Sadly I don’t have a DRO on my mill.
