Confirmed that its only poplar dust I'm allergic to.
The pickup "route" is done. Since its technically a four-piece body, I did the route by going at the top bit in two halves, using a coping saw and some files. The channel for the wires and ground to the bridge is done the same way - I took a hacksaw to the inside to cut some paths then a round file to dig them out until my wires fit. Its rough, and it works. Once the sun is up I'm taking a chisel to it in attempts to clean up the pocket.
Not pictured, the neck pocket is started the same way, and also I learned why daddy always said cut away from your body by sticking a utility knife in my leg while trying to open some nuclear-strength plastic on the clamps pictured. Ironically, the knife didn't cut me, but the plastic did.
