I've been looking at one of my long standing, unfinished projects and had a brainwave today, but it involves cutting five equally spaced, 1.5mm wide, 15mm long, 1mm(ish) deep slots around the centre of a piece of 20mm diameter aluminium stock.

These are to keep the vanes of a five spoked wheel aligned and to provide some mechanical connection. The parts will be epoxied as well, to form the main strength of the bond.

Wheel C is the real thing I'm trying to emulate:



I've had the centre disk and vanes/spokes waterjet cut already, but was worried about how to align them, and this looked, on paper, to be a good way to get everything straight. I'd have to get the vanes/spokes cut again with a tab to fit the slot, but that's pretty trivial to arrange.

Is this feasible, or is it likely to kill more bits than it's worth ? There would be 12 in a set, and I'd probably require 5 sets in total.

Adrian.
