The box cuts are from BJ Weeks, who resells them cheap from Dadant, and he's local, so no shipping!
The other ones are some as-yet-unused cypress boxes from Rossman Apiaries. Last year they showed box cuts on their website, but when they showed up, they weren't. At the time I was told they don't do box cuts anymore. Sure wish I hadn't ordered so much! I've heard that cypress is supposed to last longer than pine, but my Rossman parts with rabbets are already starting to show small problems around the corners.
I have since aquired access to a table saw, and will be making a lot of my woodenware myself. I will post pics, of course.
