Just finished my built in office bookcase, 3/4" red oak plywood and 3/4" x 2 1/2" and some 3 1/2" cherry to trim off the plywood edges. Back is 3/32 floor underlayment.
I haven't decided how to trim out the window yet. Blend in or contrast? I go back and forth.
Red oak stain on everything and finished with 2 coats water based Polycylic semi gloss.
1 shelf is dadoed and glued into the uprights all the way across and also the top shelf under the window is glued into dados.
I used Weldbond for all the glue joints.
I used my router table for all rounders and flutes. Not the ShopSmith.
Had to submit picture in 2 halves to be accepted.
