Radius Jig Plan

[Johan CrousParticipant @johancrous15881]

I am looking for a plan to construct a radius jig for the Harold Hall grinding table.

I would like to grind radiuses on HSS tool shafts and I would like to sharpen ball shaped milling cutters. I am thinking in the line of adding the Harold Hall end mill attachment on top of the radius jig or the other tool holeder to clamp HSS rods or shafts.

A picture / photograph from where I can get an idea will also be appreciated.

There is at least one (short) video on Youtube showing ball end mill sharpening.

May be helpful

Hemingway Kits supply a kit for a simply-constructed radius grinding attachment kit for the 'Worden' tool & cutter grinder – here; ..worth looking at..?

The worden radius attachment would really only radius tool ends not milling cutters without much alteration. You could copy the Clarkson attachment ? Noel.

Noel, I have done some crazy stuff in my life. I am sure I will think of something. I am now busy with an endmill jig that use a MT3 collet chuck ean therafter I will tackle this. I will keep you guys up to date.
