I'm going to post up some of the builds I've done, and am looking for a project to work on for future endeavors.
It all starts with a design.
This started with inspiration drawn from a Fender Jag, with a bit of changing dimensions, some tonal wood changes, and a nicer pot placement.
Next step would be rough cuts. Get as many of these done as possible, and allow for them to set, to find the imperfections. Beware, there will be ALOT of fire-wood as pending which wood and weather you have, you may find that splits, cracks, and knots appear beneath once sanding.
Begin with your routing for pickups and neck placement. If your not using a jig, this will be a one shot-only cut. There's no fixing poor placement unless your covering the pickups.
