Flat Panel slot size?

Easiest way I can think of is to make the cut in 2 passes on a router table. Use a 1/8” bit and make the first cut, then raise the bit 3/32 (or whatever your test cut determines to be the best fit), and make a second cut. If you have one of those digital height gauges, it is easy to make this a repeatable setup – just keep a record of the 2 heights.

Another way would be to make the slot 1/8” and then use the slot cutter to trim the thickness of the edge of the plywood panels just far enough back from the edge that it is entirely hidden in the groove. This would give a tight fit even if there was some slight variance in the thickness of the plywood.

I think you’ll need more band width for a “1/4” BitTorrent”.

I was trying to avoid making multiple passes but I think it’s the best way to do it.

thanks.

You could do that with a biscuit jointer router bit in multiple passes.
You’d find uses for the biscuit jointer bit after your job is done.

Another option would be to get Freud’s adjustable tongue & groove bit set. It adjusts for grooves from 7/32-3/8
