    I don't mind it the way it is, but wouldn't mind some other opinions.

    1. Should I try to undercut the scroll curls, or leave them more plain? I feel like I have kind of an Engelhardt vibe as it stands.

    2. Should I try to scallop the big flat middle of the scroll or leave it plain? I'm thinking that having a pair of shallow scallops starting with each side of the headstock might look cool. (But there's risk for screwing the whole thing up too.)
  2. Undercutting the curls would look nicer and also takes some weight from the scroll, but as you said, if you are not sure you can handle that, it might be risky.
    At the end only you can answer your own question.

    I'm highly opinionated and extremely self-assured
    Wow, nice! Definitely following this.

    As promised, it's time to start dealing with the fingerboard.

    So first things first, I built a router jig.

    Basically it's a table for the jig I build for the truss rods. I built a sled that goes under it that has holes on either side to set the radius on each end.

    Mounting the fingerboard to the top with a pair of screws at each end, and running the router along the jig while lifting the handle to rotate the fingerboard and in quick order, you have a multi-radius fingerboard.

    I found that halfway through, I had to plane down the edges as they started binding on the jig due to the tight fb radius.

    Now I get to do it again. On the purpleheart.

    @DoubleMIDI here's the overhang on a 30" fingerboard. I think I can live with that. Especially if I angle it away from the bass strings.

    Aw heck yeah. Nothing like something going exactly to plan!

    So work has kept me busy and I haven't gotten much done, but figured I'd update the PU situation...

    In Jan, I ordered a set of Piezos.. those are presumed lost in transit at this point. According the tracking, they made it all the way to Chicago, passed customs, and the import expediter fumbled the handoff to USPS. God only knows where they are, it's possible that some time from now I will get a random set of Piezos in the mail when they are found....

    Waited several weeks (nearly a month!) to see if USPS would ever show them being received, no dice, been in contact the seller through Amazon, they re-shipped the order (Yay!)

    Order has once again made it all the way to Chicago, passed customs, and I am watching the USPS tracking number to see if they ever get it.

    I will be very frustrated if this shipment too gets lost, as I will have wasted almost 2 months trying to get the Piezos for the bass. The seller has been very responsive, and I believe that they are trying to get the pickups delivered. but they are using a 3rd party shipper that seems to be kind of an iffy fly by night operation (4PX).

    There is plenty of other things that i need to work on before this becomes critical, but I was really hoping to have them in hand well before now. I'd like to start on the bridge and get that sorted out while the bass is still in this rough stage so if I need to build out the 'pad' that the bridge will attach to I can go ahead and do that.

    So I spent a couple of hours working on the bass this afternoon. Tackled the tuners, as that seemed like a small thing that has a pretty big payoff.

    As @Amano noted earlier, having the tuners perpendicular to the strings would be preferable. So I cut a small level recess in the side of the headstock to accommodate this, I also had to cut on the inside to accommodate the washer and nut. Sanding these is going to be a chore, but no more complicated than anything else about the headstock...

    2 down, 3 to go.

    Nice work videojunkie. Stil following. Like the headstock, the size and the way you made the scroll.

    Thanks for the encouraging words. I really appreciate the support. Nobody in my immediate world understands anything about this hobby of mine.

    My wife is supportive, but it's incomprehensible to her. I might as well be making a warp drive...

    Cleaned up the bass side of the headstock a little. You can see the level spots for each tuner.

    As I continue working on it, I keep refining the scroll. Working towards a nice rounded shape and eliminating high spots

    I have to make a decision about the headstock. In the original plan, I was going to glue a 1/4" thick piece across the bottom of the open area, tapering it into the scroll at the end, and I was considering putting some purpleheart that would show on the inside of the tuner recess.

    My thoughts are
    1, would that make changing strings an unnecessary pain given the tight quarters especially for the E and A strings?
    2, is the minor structural benefit worth the effort to finish it satisfactorily.
    3, it does give me a convenient place for a logo...

    I am thinking instead that drawing the point of the tuner area out along the back of the scroll might be just as aesthetically pleasing.

  16. If you have room for at least twice (better three times) the diameter of the strings from peg to back, you will benefit from a better stability in case of an side impact on the pegbox.

    I have a ton (literally 2000 lbs!) of woodwork to do before I can get back to the bass, so I am going on a brief hiatus.
    Heavy rains and an unplugged sump led to soaked carpet and replacing the flooring in my basement.

    Hopefully this won't take too long it snaps together like Lego. Oh, and it's supposed to snow off and on for the next week!

    Thanks for the kind words. I'm glad you are enjoying it! Still quite a road ahead still.

    Can't start the floor until the concrete dries. So while that happens, my wife sent me out to work on the bass as a stress release
    So, I finished up the tuning peg fitting on the treble side,
    20210320_165334.jpg 20210320_170401.jpg

    Cleaned up the curve under the fingerboard.

    And started working on the bridge.

    First thing was to find center, and drill out the recesses with various forstner bits and chisels.

    Tomorrow, I will see about routing the various depth flats for the 4 additional bridge ends.

    Laying it out with a straight edge, I was able to get a glimpse of what the string action might look like.

    I was also able to see what the neck is going to start looking like...

    Excuse the mess on the workbench!
