Hi,
I would like to cut a slot for a bearing in a piece of 1/2 round aluminium as per the attached pic.
The problem is that I cannot find a slotting cutter with a small diameter shank.

I can only think of a standard 16mm T slot cutter with a ground down shank, to say just under 6mm to fit into the 6mm dia 1/2 round slot that runs up to the bearing location.
The 50mm dia rod will be cut in half lengthways then pinned back together and re-turned back to round.
The 6mm hole is then drilled, the 2 halves separated and the 16mm x 8mm deep slot formed.
Bearing thickness is 6mm.
Once the slots in both halves of the rod have been machined the bearing is inserted and the halves pinned back together.
Any ideas on how to cut the slot, please?
Martin
