Spoil board is too low to low to get full depth I need but I would be able to mark it out. I probably need to go with dog holes though thinking about it. If I hit t-track with the laser I intend to attach might be bad news. But your work bench in general just larger is what I wish I had built. Drawers would be really nice too but besides a piece or two of plywood I built it nearly completely from scrap I already had laying around from other projects or things left behind by previous owners of the house.Use your CNC to cut the holes or track into the spoil board. Mine has enough Z travel to go through it. If you are doing T-track bury it below the surface so you can still surface your spoil board.
