Wow. Thanks for all the great advice! Apologies for not coming back here sooner, but I didn't see the thread updates in my email until just now.
I had 4 long (34") shelves glued up in the center from two panels tongue and groove.
I had 2 short (17") shelves glued in the same fashion.
I had 3 short (17") shelves glued up butcherblock style, made from the scrap trimmings of the above shelves.
Anyway - after a lot of googling, I found that my local Community Center has a fully stocked woodworking shop available for $20 a day. I headed down there and got everything fixed up by:
1) Passing everything through the jointer about a dozen times to get a fully flat surface (Some pieces more, some less)
2) Passing everything through the planer about 4 times to get a fully flat face
3) Running the sides through the jointer a few times to square
4) Table saw to true up the last edge
5) Miter saw everything down to final lengths
Honestly wish I knew about that shop a month ago, would've made my last project easier!
The guy at the woodshop ALSO said not to worry about doing a joint for the boards in the future, that the glue is more than strong enough on its own.
I spent a few hours routing out channels on the under-sides of my shelves tonight so they can sit on the crossbars of the ladder frame I'm using. A couple hours tomorrow sanding should finish everything up before I treat the wood. I'll be searching the forums in the afternoon to figure out the right progression of water to tung oil to use....
Wish me luck and thanks for all the advice!
