This morning as I went to machine multiple connecting rods for the radial engine I am building, I decided that a vice stop would be very handy for doing multiple set-ups. This is my low-tech solution, and it works quite well. Don't rag on me about the weld--I did it with my little mig that I use for sheet metal, and it really doesn't quite have the oomph required for a good "burn in" but for this it will work fine. I welded a huge washer I found to the head of a 3/8" shcs., then faced it on the lathe. The angle is a peice of alumnum out of my 'scrap bin". I lucked out and found a couple of T slot nuts that fit my mill table. It doesn't look elegant, but it works, and is another handy tool/fixture for my ever growing arsenal of home built solutions.---Brian

A couple of ideas for "improvement".

You may well need a stop in the center of the jaws rather than hanging out the sides. If you drill a hole in the edge of the disc and thread a bolt through it you will be able to extend the stop point either between or over the jaws.

Cutting a slot in the vertical stand will allow you to adjust the height as well.

Depending on the precision you need, that disc may not be sufficient. Unless it is perfectly vertical, your measurements may vary a few thousands depending on where the edge finder touches.

Just my .02
 
Some bondo spread over the weld, Some sanding to smooth it out, Then a coat of Paint and your job will look perfect. If the weld is more than strong enough for the job required then looks really are not that important.
