Five string fretless build starting

Discussion in 'Luthier's Corner' started by Jisch, Nov 2, 2016.


  1. This will be a slow build I suspect, lots of other things vying for my time at this point in my life, but I figured I might as well start a thread.

    Specs:
    Double cut 34" scale through neck five string unlined fretless
    Body: Black walnut back with a thick figured maple front.
    Neck: Wenge with maple and black walnut stringers
    Fingerboard: ziricote with both sap and core woods (wavy brown/white)
    Electronics: Lace Alumnitone pickups with Audere preamp

    In some ways this will be a re-build of my wave bass, improving on a few things here and there:
    • I may or may not do a CA coating on the fingerboard - the ziricote is really dense and I don't think it necessarily needs a coating on it if I stick with flatwounds, but I did like how those roundwounds sounded
    • I didn't like how the red cocobolo on the wave bass contrasted with the other woods in the bass, so using ziricote gives me the same wave, but it's brown, not red
    • I was 50/50 on the "single cut" aspect of that other bass, it took a lot of time to make and really not worth the time.
    I've got some of the neck stringers cut, and have had to work a warp out of the board I'm going to be cutting the fingerboard from. Hopefully I'll get that taken care of this weekend.

    I'll get some more pictures as I go, but here's the top I'll use - I haven't decided how exactly I'll lay out the body on this:

    Neat wood! Sub'd
     
  3. I just recognized the figuring in the wood looks a lot like an ostrich. Of course by the time I get the body laid out I doubt you'll be able to see much of it.

  4. This seems to be the best orientation - this picture is a bit darker than the actual wood, but probably close to what it will look like with oil on it.

  8. Thanks, I feel like I'm dabbling right now, I have to rely completely on my dad's shop, it feels a bit weird after getting used to doing stuff at my house.

    I'm not the most reliable after 9 pm though.....:)

  11. I got 30 minutes in the shop today, and was happy to get that time. Hopefully things will slow down a bit now that we have our contents list in and builder selected (of course there are a thousand more things that need to get decided upon, honestly more like a million).

    I got some maple strips for the neck cut and planed and the ziricote for the fingerboard cut. The ziricote is super hard - I had a really hard time getting it through the sanding planer. I can usually take a 1/4 turn on the planer and be fine. With the ziricote I had to take 1/16 turn and turn the feed up as fast as I could even then I made a lot of smoke, jeepers.

    The neck will be a center of wenge, maple stringers and walnut on the outside.

    The fingerboard looks good, but I think a cut deeper into the wood would be more variety in it, we'll see (the one on the right is the one that is the proper thickness):

    That top wood has some serious chatoyance going on!

    Yep!....I had to look it up :whistle:....

    In case anybody else does...

  14. I can't wait to get some oil on it and see how it pops. Realistically probably 6 months from now.

  15. I spent some time today planing down the two possible fingerboards, I'll do a lot more staring before I decide, I'm not sure if I'll go with a little white (left) or a lot of white (right). I don't even have a "leader" in my head right now. This wood continues to be difficult to plane using the sanding planer, it burns easily. I'd send it through the regular planer, but I fear for tear outs. One of these is 5/16" thick the other is closer to 3/8", so I have a bit more to take off.

    All the pieces in a pile. I should get the neck blank glued up next week.

  16. I finally got some time to glue up the neck blank. All went well. I meant to trim off the ends on the outer woods, but without a chop saw here, I glued everything up long. I hate wasting wood like that, but I can clean it up if I need to.

    I need to cut the top and get it glued up. I noticed yesterday that it has a bit of a warp to it, I'll have to see how bad it is once I get it roughed out. Then I'll have to get the back wood figured out.

  17. Neck blank out of the clamps and dimensioned:

    And I worked with my wife on the placement on the front wood, different than what I posted above. I worked out the shape a bit, it will evolve a bit more as I go along, but it will be something like this - my cardboard cutout was off a bit on the important dimensions.

    The joint between the two pieces of the front is close, I'll need to work on that a bit, the right side has a bit of a warp to it, I'm going to try and heat it up and get some of the warp out, but I'll probably have to do a bit of planing too.

  18. The top had a bit of a bow in it, basically a radius across the short side. On my last one I straightened the board out by wrapping it in a wet t-shirt and heating it up with a plumbing torch. I don't have a torch here, so I used a steam iron instead. It seemed to work out well, I'll let these boards sit for a week or so (traveling for work this week) then plane them and recut the joint between the two places.

    I put the board on two 2x3s then used a ratchet strap to pull the board a bit below flat, steamed it with an iron for 5 or 10 minutes then let it sit with the ratchet strap on for 3-4 hours. I'll clamp them up while they dry out.

    Nice! I hope you bought your own iron. ;)

  20. Actually that's a rental iron, if you can believe it. The insurance pays for a "fully furnished" house, including an iron apparently :-D
