I just installed an oxa tool post
I used a M10-1.5x75 bolt, I cut the head to 14mm x 3mm thick and if you can tell I off set the flange and cut the thickness from the underside of the head to make sure I had enough height for the stud.
When I removed the existing stud the the through hole was off center in the counter sink, the original post was a tight fit in the hole but had clearance in the countersink and was not off set to match. My M10 bolt wasnt going to fit as tight and I thought I would have to put some sort of key to stop it from spinning and then I had the idea to off set the flange. I measured about 60thou difference in the centers so I used my 4jaw chuck and it worked pretty good, I did do a little filing to shape the flange
I used a single 3/4” washer to raise it above the raised boss on the compound and I had to remove about 1mm off the top of the boss to come flush with the washer. As you can see I was able to use the original tool post top bolt and handle, while tightening it down I could feel the stud turn and lock just like Id hoped it would. So far Im very happy how it turned out.
