I have a cheap HF indicator with the standard pointed tip. It works fine on the TS for blade to miter slot adjustment. However, it is not very good for use on my jointer - the tip slides off the cutter edge too easily.

I have seen fancy indicators with broad 'mushroom' tips that would work better on the jointer. I see the tip is screwed to the shaft with I would guess is a 4-40 thread.

Does anyone know of a source for the tip?
