i was thinking of this today , as i am not currently in my own personal residence where i could bolt things to workbenches , or make a big tillering tree area on the perfect walls , but i could put something together that could easily be packed for moving , or whatever. im going to play around in sketchup , if all else fails , ill draw something or worst comes to worst mapaint....
what i was thinking anyways , is taking a 4x4 or two 4x4's , lagging them together , and building an adjustable square sliding piece , that would slide over the end , and have either a big platform or something to mount a vice on , adjustable in length via pegs , and rotatble perhaps , the legs i was thinking something like another piece of 4x4 , and a door hinge , but have the end of the 4x4 hang over a bit from the hinge , so that when opened , it would but up against the back of the two lagged together , limiting the travel...
of course there would have to be a seat , and i suppose it may be easier to have the seat moveable , instead of the mounting platform , which now that i think about it , it could be slid through the lagged bits , and held ...oh hell , paint here i come...
