Thanks Dutchy... Roundovers should be clamped, however, that would mean changing clamp position 12 time per cube (216 times per set) and then many edges would need to be sanded to remove some of the router burns... too much hassle and easier to bevel with disc sander for something mass produced and given away for free.
If your first cut is too short... Take the second cut from the longer end... LBD
