2 piece milling vice

[Stevohdee]

Super clean build Steveohdee, and gas cylinders are another recycle in common. I like that you can put almost any size into it and hold it well, and have often thought of this kind of vice but concerned
about keeping the jaws parallel because of the slop in the T-nuts. I guess you could tram the jaws each time it's set up for the size work to hold. Do you have another way or is it even important?

Thanks for sharing a fine build with us.

Thaks pj,
to set vice up i just square both sides with set square against mill table then tighten down, no need to tram.
Cheers stevoh
