as requested im giving some more information about the homemades vises i made.
it’s actually quite simple and cheap to make if you can weld, and better yet have a metal bandsaw.
they are all based on threaded metric rods, they are cheap but they take many turns to advance.
i added a sketchup sketch of a the principle, parts with the same color are welded together, it’s not verry different from regular vise mechanisms.
they can be made in a couple of hours, with less than a $10 cost, though you need to buy minimal lengths of steel.
the first ones i made using squares that glide into each other, they work pretty fine. then the last ones i made were made with special steel parts that are used for making hinges, those are more accurate and durable, but you need to be precise.
for a good vise you need to be precise, 1mm of play means you need to make a complete turn before the vice moves.
these are never as good as quality cast iron ones, regular steel does not like the friction and wears more quickly over time giving more play. i use them daily and my oldest is 1 year old and it still goes like day 1. but i guess it won’t last 50 years.
not ideal for professionals, but depending on the use it can be given a second thought.
i think it explains itself mostly, though if theres more questions don’t hesitate!
