On my third build, which has been reduced to more hand tools than power tools since I moved to an apartment, I've decided I'm going to for for a cavity cover matching the back of the guitar.
Here's vaguely how I think I'm going to achieve this:
The guitar is super skinny - a 13/16" limba base with a 0.29" spalt maple top.
Before I glue the top down, I'm going to saw out from the limba the entire area of the cavity cover - sawing along the black line here (this is the back of the guitar):
I'll then take the plug I've sawn out, and slice off the top 1/16" or so to give me my actual cover.
With the rest of the plug, I'll mark out the lip for the cavity that the cover will sit on, and drill/route it out:
and I'll glue that ring back where it came from, before gluing the top on:
so my questions are:
1) is this method sound, or is there an easier way?
2) what hand saw can I use that has a kerf thin enough to achieve what I'm trying to do, but will still cut through 13/16" of limba without two many hassles? I feel like a plain old hacksaw might be too thick, but maybe not... any thoughts?
I realize a scroll saw is almost certainly the easiest tool for the job but I don't have one, and I'm not going to buy one, given my limitations of space, noise, funds, etc.
