Fill in my knowledge gap :)

The slot is pretty wide so i would position the material to place the eventual slot over a run of bed holes, machine the slot plus the two small ovals, then fit clamps into the slot and finish the rest of the front.

As you said, then place blocks on bed touching the finished edge, flip over, clamp around the edge and machine the pocket T.

Seems to make sense now, will finish the drawings and do a simulation or two :)

Thanks
