I have a theory about how to seam panels of aluminum, and was wondering
if anybody has heard of such a device.

I have thought about just skiving the edges of both panels to thin
knife edges and lapping them, but that woories me more.

Instead of a tongue and groove, why not a shiplap joint? This would
probably be easier to machine and your thinnest dimension would be .045".
Just a thought.
