And of course, we have to get the router busy on this tomorrow.
The template's not positioned properly in this photo. That line isn't the nut - it's the start of the headstock curve.

I might have cut it too close where the extra "ear" is glued to the top of the headstock. It might be a case for SUPER KNEADABLE EPOXY PUTTY!
Mental note: draw the nut line on that template before drinking another beer.
The whole thing weighs 1300g (2.8 pounds) so far, so with the truss rod it'll be about 3 pounds - but then there's a lot to come off yet. So I'm thinking about 2 1/2 pounds for the through-neck.
The tuners will weigh 1/2 pound, and the bridge will weigh an ounce or two (when I build it). Frets will weigh 0.00g. Pups will weigh a ton! Nice and FAT. I'm thinking low-riding wide coils over AlNiCo V poles. P90-ish. I'm going to try something weird with the pickups.
We're aiming for well under 6 pounds.

There's a hint at the body type.
