Update: Sorry for the delay
They sit level. They are by no means perfect, but that's ok b/c they are supposed to be "old/faux distressed" black wooden crates I am using for speaker stands in my home theater setup. They are almost done, I just need to finish the polyurethane (right one needs 1 more coat, left one just finished staining) and sand/clean 'em up a bit.
Thanks for the tips :thumbsup:. Yep, I ended up cutting down a couple scrap pieces of wood and making a sanding block similar to how you described and used 60 grit, then finer, etc etc. I did the same thing to shorten the back slats about 5/8" (after using a hacksaw first on those).
