milling radii
(OP)
i am trying to locate an OLD formula for milling a radius. this method allows, for example, a 2.5" radius to be milled using a 3" diameter milling cutter by tilting the vertical head to a prescribed angle and utilizing the milling cutter like a fly cutter.
this same technique is sometimes used on radial arm saws to cut a radius for making molding.
i had this written down many years ago and have misplaced it. i know this isn't a very accurate or precise method but it eliminates the need for a variety of cutters to mill shallow radius using a toolromm type milling machine. such a radius is needed for a bronze shaft rest pad on long leadscrews.
thanks in advance for the help,

i came out of an old us steel facility that still made their own gear cutters and hobs from scratch in the late 50's, never bought anything.

I am try to mill , 1/2 cylinder concave shape. 8" X 1.6" and the Radius is 1.62".
I don't have CNC nor I know how to use CNC ( newbie here ), only have sherline milling machine.
any tip would be greatly appreciate.

But (I hope) I'm not too proud to know my limits, and those chaps with the fingers missing are the guys I turn to first when I get stuck. And they help out a lot, once they've finished trying to get me to go and get a sky hook....

ok.. how and what do u mean by "shimming up"??
as for Sherline Milling machine, the arbor are about 1 3/4" long :(, and i can not find exact 1.6" radius cutter.
