I trust there will be loads of plans out there to construct your own woodworking vice. Let me mention some of our members who are keen at woodworking @woodenwookie, @r23on and @Poppop to see if they could lead us in the right direction. I know the woodworking vices we used back in wood tech at school were fantastic.
You might be interested in possibly starting with a Craftright 175mm Wood Working Vice and building your own jaws for it. You could build a certain portion of a woodworking vice but I believe you would need to buy the screw mechanism.
