    Kinda surprised you went for wood instead of carbon fiber this time. :laugh:

    It’s easier to try different ideas with wood. Carbon fiber needs molds and it requires lot more time and money to do different versions. And to be honest I like working with wood more than with composites.

    Yeah, working with composites must be a pain... and the dust is much worse than wood's.

  4. Right there are most of the reasons I hate composites... and the mess... and not getting the right amount of catalyst in the resin... ever... no matter how hard I tried... :(

    One reason (besides the smell, which is a huge reason) Epoxy >> Polyester.

    So what else could I, a leftalone do?
    I routed the cavity for bridge block, made the block and epoxied it in the cavity. Bridge screw threads will be made after the epoxy has cured.

    And after making lunch for us boys (son went back to swimming) I made a new headpiece. Sides will be trimmed after the headpiece is bolted to the neck. I try to drill holes for inserts and glue the inserts tomorrow.

    I drilled the neck ferrule holes and bolted the neck on the body. Bridge plate is also sanded flush to the top.

    Fretting is next. I have all sorts of fret wire but none enough for a whole neck. I have to call my guitarist friend and ask if he sells me some.

    I think something smaller. I’ve tried fret sizes from jumbo to small and medium is my favourite.

    I got the neck fretted. I glued the frets with epoxy.

    I used alcohol to wipe the epoxy off the fretboard.

    Earlier today I routed the truss rod adjuster cavity.

    And threaded inserts for tuners were epoxied in their holes.

    Solid, tight connections at every point that metal hardware meets wood...and then softening the wood frame a bit to let it move more. That's the underlying theme of Brucification! This bass is going to sing.

    I believe if there’s something bad about the sound it’s not the bass, it’s the player :)
    Today was just boring sanding, sanding, sanding... I filed the frets flush to the sides of the neck and drilled and glued the side dots as well. I sanded the neck to 320 and wiped the first coat of Tru oil on it. Body is sanded to 240 and wiped with damp rag to raise the grain.
    Sorry no pics as there is nothing to show.

    Me too. And it’s a joy to work with. No matter how dusty shop you have you always get a nice, smooth finish as long as you wipe the excess oil off.

    Yup, I need to look into how to work with it using stains and/or dyes so I can do body work...

  20. Could someone please point me towards some information about the Brucified truss rods?
    Tried searching but couldn't find anything :(
