This is a collar to replace the stock depth stop on a Scheppach DP16SL. The stock one is connected to a security visor or something, completely useless. To replace that crappy thing I designed this piece. You'll need 3 M8 nuts and a length of threaded M8 rod. 2 M4 bolts, 2 M4 nuts and 4 washers. I used a length of tubing and a zip-tie for the depth indicator. Just look at the pictures, you will understand.
