    So apparently I joined this forum too late and missed the $100 bass challenge (my kind of challenge :) ) but coincidentally I was making a low budget acoustic upright bass around the same time so I thought Id share some of the build photos. I think it sounds very good all things considered and Ill get around to recording a bit for y'all's critique when I get some time.

    My bill of materials was as such
    60"x60" 1/8 birch plywood - $17 (top and back)
    30"x60" 1/8 birch plywood - $11 (sides)
    alder for neck block - $5
    2"x8"x~8' maple - $40(neck, fingerboard, bridge, tailpiece)
    Ebay UB tuners - $40
    Ebay Strings - $20
    endpin neck bolts and tailgut hardware - ~$20

    So I ended up around 150 but if I had gotten cheap electric bass tuners ($9) and scrounged some hardware maybe I could have made it under the $100 mark.

    First step was making a half body mold, I made it out of shipping crates I pulled from a dumpster 1. 2.

    Next up was bending the sides from the 1/8 plywood. I used some leftover 1x1 stickers for the corner blocks.

    Then I cut out the neck block, joined the two halfs and made some temporary bracing to hold everything where its supposed to go 5. 6. 7.

    I trimmed the sides so that the top would have a parabolic shape approximately the same curvature as carved double bass. Then I roughed out the outline on top and strapped it down during the glue up. After that I fitted a large redwood X brace in the top so it would be able to hold the downforce from the strings. I forgot to include the redwood in the bill of materials, it was a $1.50 fence slat from home depot. 8. 9. 10. 11.
  5. Wow!

    Next was cutting the side taper for the back and roughing out the neck. Its bolt on with 2 1/4-20 bolts going into threaded dowels. 12. 13. 14. 15.

    I shaped the fingerboard, added some bits to fill out the base of the neck and glued the fingerboard on. 16. 17. 18. 19. 22.

    I glued the back on except for the taper and then after that was cured I used some clamps to pull the tapered part in. I also added in a sound post. I made it slip onto the x bracing on the back and top (I also thinned it out after this image was taken to cut some weight). 20. 21. 23.

    Then I realized I was within spitting distance of having it strung up and playing so I rushed and forgot to document a number of things (peghead, scroll, tailpiece, bridge). But heres a picture of it strung and in the white and with the dark brown finish on it 24. image (1).

    You, sir, are the Harry "Gandalf" Picard-Skywalker of the DIY bass world. If I wore a fedora and trench coat I would roll a D&D character in your honor.

    That is a thing of beauty.
