I’m building a wall cabinet from some pitch piece reclaimed from arts and crafts period church pews (hardest wood I’ve ever worked with!). I’ve rebated the rear edge and dimensioned some 1/2 inch thick boards for the back panel. I’m using unglued half lap joints on the boards.
What options do I have for securing the boards into the rebate? I want to allow for expansion/contraction of the boards.
I think in Paul’s Bookcase videos, he used a single screw (counter-sunk) near the center of each board, screwed into the rabbeted top and bottom pieces. Nails would work fine, too. But in each case, I think you’ll need to pre-drill because the nails/screws will be so close to the end of the half lapped boards and you won’t want to split them.
Put up some pics when you’re finished. Would love to see it.

Build a frame for the panel boards, plough a groove on the inside all around and then cut a tongue on the ends of your panel boards to slip into the groove.
Another option would be to simply tack the back panel into place in the rebate. you want a bit of space between each T&G board to allow for movement, I use a dime to give me a uniform spacing. Tack each board in the center into the rebate.
As others have said I think one pin or screw in the centre of each board would be fine. You might consider a frame if you need strength from the back, but if not then either method is traditionally acceptable.
You could look at the corner cabinet video too, I think Mr Sellers secures the back boards in the centre with a single screw.
Helpful advice everyone, thanks. I was thinking along those lines but wanted to check it out. A single fixing point won’t control cupping, but the wood seems very stable so I don’t think that will be an issue. Here are a couple of (poor) photos of progress so far. I need to chop up and rejoin part of the back of the pew to make the door. Very dense, heavy wood!
I probably rival Matt for slowness, so completion date is anybody’s guess.
