Nice boxes William.
I just finished finishing 6 band saw boxes of various designs. Just the buffing and flocking to do.
I always like the end result and the construction is relatively simple but the sanding OMG the sanding! Have you by any chance figured any good processes to minimize the pain?
If you are using a 3/16" x 10 tpi blade , the insides of the boxes will not need sanding at all if you put flocking in them .
As for the rest , I use both the belt and the oscillating spindle sander which leaves minimal hand sanding to do .
I made that batch all in one day (apart from the glue up of the blocks previously ) and followed up with the drawer flocking a couple days later.
Would love to see pictures of the ones you made .
