Flywheel pattern making

[chucketn]

I am researching making patterns to cast al flywheels. I found a drawing from Elmer Verberg’s info at the Jon-Tom website. How do I machine the tapered spokes,  shown in the drawing below, on a rotary table? I can understand the setup for drilling the corner holes for the cutouts, but how do I offset  for the taper of the spokes?

Hi Chuck

Arnold has just made a flywheel with tapered spokes and I think he mentioned using Marv's programme to do that.

If you can draw it out in CAD just measure the angle of one of the sides of the spoke and set the rotary table to that angle, do each spoke then move the cutter to the other side of centre and set to that angle.

I did just that for someone last week who was having difficulty knowing how to do this 3" dia handwheel, think he made a good job of it
