so here's the compete structure, almost. there is a second front rail with a panel in between the two that is missing from the photo. that panel has the cutouts as well. since this picture i've done the shaping and i started sanding today. it's moving along at a good rate, thanks in part to a 1/8" roundover bit. i feel like skywaker, slowly being pulled over to the dark side. i must say, it's nice on that side of things, but sometimes it's a little dusty.
i found some brass machine screws at the local hardware store, and bought them all. those buggers are pricey. i was looking for some steel slotted head screws, but those are probably impossible to find nowadays, so i bought these instead. i'm going to use them to attach the slats to the frame work. the slats have some bow in them that i intentionally left there to add some give to the seat. i drilled some oversized holes through the slats, and i'll have to tap the adjoining hole. i just happened to have the right tap for the screw as well, must be a common size.
i wasn't crazy about the yellow brass with the oak, which is going to get some water based stain, so i did a quick search about patination. i found a pretty good blog conversation in a sword makers forum, and the guy suggested gun blueing as an option. we had some, i gave it a try, and it worked great. it gave a nice dark brown which will go quite nicely with the stained oak.
