Thanks for input. The rendering was from cabinet guy the quote was $60k so I will be doing it myself. I will eliminate the double rails. It’s just the layout I was looking to do. I am essentially going to screw the 3/4 ply into studs then attach rails and styles to plywood so I don’t need to worry about the metal studs at all. Is the consensus to attach all together like face frame then attach? I just figured if I face nailed all the trim separate it would save me a lot of time. I was thinking of possibility even getting a Zeta P2 just for this application and just clipping styles and rails onto ply?
Yes, thats what I was saying earlier If every other panel is assembled in the shop in a face frame fashion then the 3 rails in between every other frame will be installed on site but I would have everything dominoed ahead of time or fastener of your choice (lamello) I dont know if I would use the Lamello but Ill let others who own it chime in on that. The reason I am shying away from clamex connector is I thought there was a little play with those so the faces might not plane out perfectly flush. Where as a Domino will/should do a good job keeping those faces nice and flush.
One thing Im not sure of, is the "3/4 ply" you are screwing to the studs red oak 3/4 ply or are we talking something like BC, MDO etc. with a 1/4" red oak panel in the frame? I ask because it looks like there will be a decent amount of area in the field that cant get screwed. If you/they install a a 3/4 "substrate you can screw everything off with no worries and then cover the screws with 1/4 rabbited into the stile and rails.
