This is the full build thread of this bass. It will be a partial build entry for the build off.I am not only posting the partial build, but the entire build here.

Here is the pile of materials for the partial build entry. Sorry for the mess, but I get too involved in the build to clean up:roflmao:

This is the build thread for my first ever bass build. It will be a 34-36 inch multiscale Schrödinger's head neck-through single cut bass. The name originates from me spelling out my last name Tok, and the guy taking my lumber order writing Teoka down, and an ancient civilization in this region of Turkey, Lycia.

Short explanation with what I mean with Schrödinger's head: it's a headless bass with some extra wood where the headstock would normally be. This idea came to me when reading @Beej double entandres in the sbo22 thread. (spoiler alert)

As I won't be able to finish in time for the 2022 SBO, I will submit for the 2023 WBO, as a partial build. I will document the full build here up to the build off, at which point I'll post the pile of materials on my newest post in this thread, along with at the beginning of this post.
Here is what I have done up to this point:


I constrained myself by only using locally grown wood. Some of you may remember me as Mediterranean lumber guy... Hello again and thanks for your help!

I decided on walnut, hornbeam and linden in this build.
Walnut, as it's not only hard and stiff, but the tiger stripes also give it a ppleasureably ribbed look and feel. The hornbeam is softer, and more easily bent than walnut, but heating and bending it over the other way helps getting a tight fit. The linden/basswood, was chosen for its nice acoustic properties. The sound it produces when spanked is to die for.


The wood has arrived, and looks eager to be grinded into a bass. The stones left and right look like they are ready to burst onto the fretboard.


I immediately began to imagine what body is hiding beneath that excess.



The neck was a nice and tight fit. The titebond glue made it too slippery tho. So a few extra Clamps (not pictured) had to help get things going.

Alright, enough double entandres.


Next, the channels for the wiring was cut. I decided that this should be done now, in order not to worry about the finish later on. I also placed some straws in there, to prevent any of the white stuff going in those holes (damn it! Another one! @Beej help!).

I also carved the belly carve and some accents on the top wing, but the photos seem to have been corrupted. I'll take pics tomorrow and post them.

Finally, here is a first design of the Schrödinger's head.


Walnut will be added as a top veneer and if needed, on the bottom for extra thickness and stability... May be overkill

It's supposed to look like an axe head... On an "axe" huh. Huh?

I'll show myself out now

By the way, I don't think you can enter this build into any Buildoff
I have to disagree. If you start already now, before the official buildoff start, then this won't be a WBO scratch build, but to my understanding it's totally legitimate to prepare pieces in advance (body, neck or fretboard) and then use them in a partial or assembly build once the buildoff starts. Just don't forget to document you "parts pile" with the WBO phrase at the beginning of the buildoff, then everything should be ok.

Looks like a fun project!

Yeah, I figured as much already, but I think I'll finish this before the build off start and enter as a non contestant... So like non voting. I mainly wanted to enter for feedback anyways.
 
Here are the pics of the carves on the upper wing.


I did this using a chisel, a scraper and a Rasp on the accent, to leave grooves to fill with a contrasting color. I'm hoping to get a brushed look there.

I'm a bit worried about twisting of the neck. Should I use two Trussrods (stewmac hot rods, non low profile) with carbon fiber, or just install one trussrod and two carbon fiber rods? If I use two Trussrods, the rods won't sit in the middle glue joint. On one tho, the trussrod would sit in the middle seam. - answered on other thread

Change of plans: I decided to not take this to Germany with me, but bring the rest of the materials with me back to Turkey in December, on my next visit. In the meantime, I have now glued and planed the body and neck

I also asked what the bottom wing is... turns out that that is also basswod (Linden). I never thought that sapwood and heartwood is so different on basswood. I thought that it was walnut.

I also got some fretboard blanks cut out of the olive.


Looks more and more like this won't be my only build

The chosen fretboard blank (not pictured above) had some tear out while cutting. So I carved a straight portion out, and glued in a plug with snug fit.

This tear out is not a big deal, as it will not be visible once the fretboard is glued onto the neck. After the glue has dried, ill sand it somewhat and then leave all boards on a flat surface to settle. Here is to hoping that they wont bend.

I added the comfort carve for the picking hand today, and rounded off the jagged cut. The top wing shape is just about finished now.

And the fretboard blank is looking amazing, if I do say so myself. I'm seeing an Eagle on the treble side... Maybe some staining to really make it pop? :drool: I have also decided to add a binding of some sort to the fretboard later on.

I'm back in Germany now, and probably won't post new updates for a while. However, I built a prototype nut out of brass, on my other bass.


I used a rod bent to the radius of the fretboard and a u channel ground to the same radius. It adds more sustain compared to a plastic nut -although that isn't a high bar to clear. It also gives a more raspy sound without a buzzing, which I like.

This way I want to avoid a 0th fret, since brass is conductive. I don't like the aesthetic of a 0th fret.
 
I was back in turkey for Christmas, but got too involved in the build to post a blow by blow. Here is the pile of materials once more


Once there, I immediately started with routing the channels in the neck. Unfortunately, the router I got for peanuts had a bad bearing. A trip to the auto parts store and 30 minutes of TLC sorted that, and the build can pick up where it left off.


Afterwards, the fretboard can be glued on. Since olive is a tearable material to work with, and I got impatient, I decided to glue it on using epoxy. That filled in the small tears on the bottom side.


I also did the cavities for the Pickups and electronics. I left the cover plate for the electronics in Germany, as it is basically diy plywood from veneer topped with some thin cherry veneer, it wanted to warp. So I left it in my bookshelf to acclimatise and cure fully straight.

Now I can start rough cutting the neck profile, using an angle grinder with a flap disk for the bulk, and refining using a draw knife and a scraper.


I kept pushing the fret slots off to future me, and started staining the body and neck using textile pigments. I got it as a powder from a German drug store. Rit dye is way too expensive over here, but would have given a much better result.


After staining and having rounded the fretboard to a compound radius (14-17 inches) , I noticed that the bridge pieces would be too high. So I routed out a section.
Finally the bass was almost finished. I coated it in boiled linseed oil and a homemade paste wax on top, with 2 layers of mica mixed in. I got some strings once I was back in Germany, and filed the nut. And I gotta say, she could have looked better, but I am more than satisfied for my first ever major woodworking project let alone bass build.


I forgot to mention that I used the same brass u channel used as a base for the nut, as an insert to hold the strings.

Some info on the electronics:
Passive Pickups, individual series(humbucker)-split-parallel switches, a single phase reverse on neck side, volume, blend, tone, bass cut.

That color looks fine to me. I always dig a headless with a Strat jack plate on the back.

I don't dislike the color, but it could have been done better.
I decided to go with a jack plate on the back, because it not only looks better, but makes a headphone preamp easier to use. With a jackplate on the side, it interferes with most seats, and makes holding the bass upright impossible.

I really like that fender recessed jack on the back. That's a really cool detail. Probably going to steal that.

Really lovely bass. Turned out very nice!
