Creativity starts on PAPER. If you just go sawing away randomly looking for inspiration you’ll wind up with sawdust and kindling.

The design decision to use sliding dovetails instead of straight tenons makes the bottom impossible to insert into the dados.

The only solution is to change the (faulty) design.

You can’t cut the bottom off one end as the corner posts will block it from siding.

You can toss the dovetails and make a conventional tenoned box.

You can butt joint the bottom but this leave the extra dado showing on the inside. Or you can use a thicker butt joint bottom to cover the extra dado. Or you can shorten the box to eliminate the dado.

If you clear cut the insides of two of the posts so they end in a rabbet instead of a dado you might be able to cobble it together. But the errors will show.

As a design engineer the creativity happens on paper. If you have to pay for labor and spoiled materials you do not just try to unthinkingly cobble designs.

Everything should be drawn (back of envelope is ok) before you start to:
  • Prevent errors like this
  • Establish design copyright
  • Document the design in case it sells and you need to make more than one
  • Accurately estimate materials and process flow

You skip these steps at your own peril. Again the 6P’s apply.

First: THINK
