I wasn’t going to do anything other than cut out the bits and the half laps, but one thing led to another and I know this seems hard to believe, but there’s more to this sucker than is apparent so I thought I’d glue it together while I still remembered which bit goes where.
Naturally while I had the dado blades on, I cut a few more things not LR related, made a mess, and when it came time to assemble this frame both my pin nailers died! Very curious that, and if the torsion box innards weren’t just there to hold the skins apart, I might even be sad, but they are and a few clamps while the glue dries is fine.
I like to glue the frame in a torsion structure first, because it allows lots of mucking around, levelling and squaring when the skins go on without having to worry about misalignment.
