centering round disc ?
1/8" thick 4" diameter steel circle.
has a 1" hole in center. I want to stack many of these and drill holes in them. How can I get these disks to center on the rotary index table? Someone had this idea: use lathe to taper 1" round stock to a point. The point is center. Put this in the center of the rotary index table (it has a small indentation at center). Drill a 1" hole in a 1/2" thick piece of steel. lay this on top of the index table, with the 1" tapered round piece going through the hole. The taper goes through the clamp "ways" on the rotary index table. The 1/2 " steel is to keep the tapered 1" rod 90 degrees to the table. ***** #####*****###### -----1/2 " steel with 1" hole drilled in it -----*****------ ---- top of index table # *** # # * # ------------ "clamping ways" on index table O \_____small indentation in center of index table. There must be a better way? Rich |
