Mostly as a convenience. The drawers are numbered in permanent market on the drawer bottoms, but it is marginally quicker for me to keep track of them as labelled. In theory, when I do final fitting they should all fit in any opening, but they will have more even gaps if they go back to the one they were primarily fitted for. My son plans to label them with the different Pokemon types when we are finished.
I did a small thing today, but it let me scratch another line off the final punchlist, so that was good. I had previously milled some tenon stock for the floating tenons, and today I cut and fit all the forward tenons.
Nothing fancy, just mark to length and cut quickly with my $15 Zona saw. That thing is remarkably useful for the money.
Just in case someone tuning in doesn't want to look through nine pages of pictures, there are holes in the ends of each of the cross pieces to accept a tenon, and a hole in the rail itself.
When I've done my part to perfectly center each mortise and align the mitered ends as best I can, everything fits where it is supposed to and looks reasonably aligned.
With everything tenoned into place, the structure is very rigid and still reasonably square, which is good. At this point, there is still not a drop of glue in this project, but it is fairly stable.
The only parts I have left to cut are the drawer guides, but it is going to take a while to taper them to the front and back supports. I might skip ahead a bit and start gluing the panels as I find free time in the next few nights.
