Looks Great. I have spent the last 2 nights gluing down cork (50 pieces). I have to go to the LHS on Fri to pick up 5 more pieces then I will start cutting out cork pads for the turnouts (I recieved a large roll of cork for free). Once I get all the cork down I will try to post pictures.
Did you find that additional joists were needed? It seens that in the first benchwork pics that you are spanning 32-42", had no rel reference. Even the best birch 1/2 ply may need at least 24" for a min. Just wouldn’t want you to find that some critical areas could have the plywood sag or bulge from humidity or any excessive weight from scenery. Like I say, had no ref. to the joist seperation. I would have used 1/2" birch on 24" centers as min. A lesser grade of ply (1/2" CDX esseciall if not 4 ply fir) should be on 16 center to absolutely stay put.
