Building My Knockdown Nicholson Workbench

My first workbench will be a variation of the Nicholson bench that can easily be disassembled and stored flat if necessary. I'm using the plans from Lost Art Press. You can read and see more about this bench here.

I've chosen to use fir from my local home center... Seven 2x12x16s. So far, I've identified which boards will be used for what pieces (based on characteristics of the wood like checks and knots that will have structural and/or visual implications), rough cut, milled and glued up the legs, and begun drilling the dog holes in the front and back aprons.

Legs glued up:
