Test fits of the end panels, not going so well. Lots of gaps. Had to go back and re-do a few things. Couple cuts were even out of square. What I get for rushing things.
Reset the corded router, with the “right” bit, a 3/8” straight cutter. reset the fence to be a wee bit more in the center of the board’s edge. Ran all the grooves through, again. But, at least things are now set up for the front and back panels. Checked the raised panels, yep, they were off a bit as well. Clamped them up in a vise, grabbed a block plane and reworked the edges. Some were rounded a bit, they are now flat. Some had high spots along an edge, not anymore. One had a little bit of out of squareness to one end. Shot the edge until square.
Had a few tenons to cut, to the new size. Less saw work, and less work with a chisel to pare them flat. Tenons were to be 1/4” thick, now are 3/8” thick . I just saw down until the groove is even with the bottom of the saw’s teeth line. Then a chisel to knock off the waste. Pare to the saw kerf.
Test fit as i went. When I had enough parts to clamp one panel up, into the clamps it went. Then onto the floor, needed to clear the bench top for the next parts. test fit as I went, again. Both end panels are about ready for a glue up. There is still some gaps, small ones. A little sawdust and some glue to fix that up.
