Hey Robert,
this looks very nice.
The dust groove is a plus.
Would you share the source for the screws and the handles and how you modified them?
I have another question: On the frame, did you do mortise and tenon joints there, or are the 4x4s just cutting edge to side, and bolted through? I mean the cross pieces. I see you have joints at the corners.
How did you attach the feet to the bottom and top frames?
