I fabricated and added this stop arm to my Evolution chop saw to allow multiple small parts to be cut all to the same measurement. I needed a bunch of 2" aluminum square tube pieces cut to a 2 inch length so this was the perfect time to make this jig. (it works perfectly!)
It's made from 1018 steel mostly from my scrap bin. A round "socket" is permanently bolted onto the side of the saw. The rest of the stop jig is stored in a nice aluminum case I had saved from a lathe tool set I bought years ago. (I knew I'd find a use for that!) lol
Just insert the stop arm into the socket and snug down the allen set screw. Then set the stop collar to match the length of part needed. Once that is set, you can move the stop arm up to it, set the part in place and move the arm back again for safety. This allows repeatable parts cut all to the same length. In my testing, I made 10 pieces and all were exactly 2 inches as I set it to.
In my case, I was able to leave the stop in place by putting it at the back edge of the part because I had no binding. After the cut was made, the part jumped forward and did not get pinched however if you experience binding, you could always use the method I mentioned with the stop collar moving the arm away each time a cut is made.
This mod will work on cold cut chop saws like mine or the abrasive type and even on band saws!
