Need help with rotary table project
I have a small 4" sherline rotary table that i have never used (came with the milling machine package) but I now have a project that requires a concave arc within a 1.530 -1.535 radius on .375 thick x 1.750 wide x 6" long aluminum bar to be fastened to a 1.530 O.D. aluminum collar. Can anyone possibly instruct me on how to do this, or guide me to a website tha covers this, please? It's my first commssioned piece and I thought it'd be easy enough, only I don't know how to set this particular job on the rotary table to cut said arc.
