Here we go again I'm starting on basses 2 and 3 (and 4 as an experiment). #2 will have a maple burl top, bubinga lam, and Af. mahogony body. The burl is somewhat soft wood, and I'm wondering if I need to treat the wood with anything to harden it so that the knobs fix securely to it without damaging the wood? Or, do I need to go fo a specific finish that will harden it. I was originally considering a satin polyurethane, but am up for suggestions... Bass #3 will be walnut burl, wenge lam, and walnut body. Larry (who is THE MAN, in case you didn't know) mentioned that some luthiers fill in the small holes in walnut burl before finishing. What do you use to do this, or do you not fill them? Bass #4 (experiment): Got some chunks of walnut (very nice curl, but they milled it so that I can't take advantage of it) and a plank of bloodwood. I cut/planed it all so that I could glue up a multi-piece body with alternating strips. The neck will be walnut and bloodwood: I'm hoping this mixture will produce a stable neck. Anyone tried this mix before? I'm taking my time with these basses and slowly picking out the hardware and electronics, learning wiring, waiting for a 6 string set of Fat Stacks to be wound, etc. Hope to have some pics at some point.
