Introduction: Transformable Headless Travel Semi-Acoustic Guitar

About: I am a physicist. I am a developer. I like to build musical instruments.

I have created a few guitars and other musical instruments. Because of that, some people ask me to create an instrument. I have done a couple of regular projects.

As for me, the real instructable story might be about something unique. And, I think, this story bout that.

One man writes to me "I saw you make nice guitars. Can you create for me one? I want acoustic travel guitar which I can plug into an amplifier. About form, make everything you want."

It was really tricky task. I like guitars with long scale length and asymmetric courageous form. Travel guitar is a small thing without the form.

But, not for me.

Step 1: Generate the Idea

The idea came from the gaming mise Rat. These mice can adjust the form for different hands.

What if the guitar can make it too. Creating a guitar with small movable parts was to difficult. But, a transformable guitar was wary possible.

To make guitar smaller with the long scale I decided to create headless guitar.

Step 2: Tools and Materials

Materials were like always any hardwood from reсycle bin. Even fretboard was pice of an old yacht. And carbon fiber truss rods.

Side wings made with plywood which I found somewhere near reсycle bin.

some frets. Inductive pick-up - maxtone single. Rear, piezoelectric pick-up - "avzhezh music", for someone is noname.

The most interesting thing of all guitar is the rear bridge. It is real peace of engineering art.

Tools:

jointer, drill, sandpaper, and other tools for wood.

Hemostatic clamp - for placing electronics inside the guitar.

10 batteries for craft shielding paint.

Step 3: Body Creation

I made the neck, the frame of the resonator, and glue those together.

To make the sound of resonator lauder its high cover I made from beech and low from oak. This has to make

interference because of the different speeds of sound in different wood.

Side wings I made from plywood. The blueprints glue on the wood and cut it with a hand router. If you want to do some like that, I mean the thing with elegant design, better to use solid wood, not plywood.

To make guitar stronger I use carbon fiber truss rods. With hand router made the groove and glue carbon rods with epoxy.

For quick mount of side wings, I make up a hook on it and box lock on its and.

Step 4: Shielding From Used Batteries

I understand that I will have wire in the resonator and this might have electromagnetic shielding. I could use a metal ducktape. But, most of them have resin-based glue. And with time resin-based glue can dry. This means with time a lot of metal tape inside the box wich makes bogging rattling and noise.

So, I started looking to shielding paint. When I saw its prise in that moment I finished look at that.

I started the search of replacing shielding paint and find the video, which shows how to make shielding paint with graphite lubricant and water-soluble varnish.

But, or I don't want to search inside the DIY store, or maybe I am lazy cow, this no one knows, I make up how to make the shield paint with old salt battery.

Salt battery have anode made from carbon. Graphite is one of the states of carbon. So, I disassembled the old battery. I gut all carbon from it. I dry and grinned carbon. After I sift dry and grinned carbon.

Finally, I mixed carbon with varnish and paint with it inside the resonator and low cover.

Step 5: Non-invasive Guitar Surgery

Another Interesting task waits for me "connect all electronics inside the box".

So I made a big hole, after surgery, I will cover it with plugin cover. I mount all wire, reostats, and switch out of the guitar. And, after, place through the hole with the hemostatic clamp.

Step 6: Finish and Souncheck

Finishing:

I painted side wings with black varnish. It was the hardest and most boring process, with failures.

The guitar I varnished with oil-wax.

As a result. It was an interesting project with difficult challenges.

And now I want to build some 8-string multiscale transformable headless travel guitar to play in any point of the world.

    Great project.Well done! Would it be possible to post pictures of how the strings are attached to the string anchor at the top of the neck and also a close up of how the strings are attached to the bridge please. Thanks. Keep Safe.

    Thank you so much. I have an electric guitar where the neck has broken just beyond the nut, so I think I can repair it with one of these bridge kits. I'll record my efforts. Thanks again.Keep Safe.

    As for me, best way to repair guitars wood part it is glue with good Polyvinyl acetate glue. You can send me a photo and I make an advise.

    On an episode of Shark Tank, there was a father and son who had invented an acoustic guitar with a neck that folded for travel, that would stay in tune when unfolded to play.

    Question 1 year ago on Step 6

    can you add some explanation on how to string and tune it?

    what is going on at the top of the guitar for a nut and to secure the strings?

    the rear bridge, did you have to drill out the front of the body to get it to fit?

    Thank you for the question. Secure, you mean, Is this mount safely?
    The detail is L-kind, and angle of it less than 90 degrees. It works as a hook. Sсrew has not any power function.
    The rear bridge mounts on 4 screws. To make it stronger on the back of the front cover I glue little bar.

    for some of these assemblies you have to use a router to hollow out part of the body to fit the headless bridge, I was wondering if you had to do that. While we are on it, I don't understand what I need to buy or assemble. looking at the guitar from the top down:

    1) do you call the part that is BEFORE the nut? in the link that you provided is that part included? do you have a close up picture of that?

    2) what did you use for a nut?

    3) at the bottom of the guitar, you don't have a regular guitar saddle, bridge, tailpiece (bridge usually made out of artificial ivory these days,) but rather its integrated into some kind of combination tuner, saddle, bridge, tailpiece thingy that for the life of me no-one online will explain how it to install it, and WHAT IS NECESSARY at the top of the guitar to make it all work.
    I've built several cigar box guitars, and would like to build a headless one, but I can't find any decent directions of scratch building a guitar with this kind of assembly. Even the manufacturers don't have any decent directions or explanations. I would be very grateful for a dummies guide to this kind of string attachment system for a guitar. Does the parts you linked to work well? Mind you its really expensive (for me,) and I don't want to end up with nothing usable when done. Thanks

    1. this part included. I attach the photo.
    2. For nut, I use thermosetting polymer which uses in high voltage electric frames. It is very hard and looks cool.
    3. The bridge is technological enough. String tension stays in tune. Only one thing is a compromise, I don't know to call that in a different way. The saddles are little drums mount on side of weel. If you want to change the high of string you change the scale. Because you rotating little weel. But this weel fixed with screws and it fixed where you fix it.
    Ask anything you want.

    thank you for the answers, so in short there are 3 parts to buy,
    1) the string clamp that you just put a picture of in this thread (do you have a link for the one you bought you can post?)
    2) some polymer nut that is cool looking (link?)
    3) the saddle/tuner/tailpiece/bridge thing that you linked, here
    rear bridge. ( https://www.aliexpress.com/item/4000151341284.html... )

    4) and for the functional components of your playable guitar that you have to buy:
    a) the fret wire (or make it yourself from old steel guitar strings. )

    5) now to electrify this you used
    a) one store bought pickup (link?)
    b) a piezo buzzer
    c) 2 500k potentiometers, one for volume one for tone control,
    d) 1 spdt switch to switch between the two pickups,
    e) probably a 4.7mf capacitor for the tuner,
    f) 1/4" surface mount mono jack,
    g) some 22 gauge wire

    6) and finally your side wings have an ingenious hook and clamp assembly/clasp. Do you have a link for those bits of hardware?

    I think that is the complete BOM (bill of material) for this build that needs to be purchased, Would you please supply the links for these parts?

    I would really like to copy this guitar.

    1. This part exists inbox of the rear bridge.
    2. This polymer I found near the recycle bin. I build a guitar from recycled materials. Old cellphones were built with this material. It cols 'Carbolit'. You can use bone. Once I took the bone from a dog, and make a nut with it. Bone is better.
    4. Fret wire I bough in the musical shop "struny.ua". https://struny.com.ua/product/sintoms-210128seh-l... . It is weird to buy something in the USA (looks like you from there) from Ukraine.
    The capacitor I took from old power block.
    Advice. To better ergonomy, you have to set electronics to the right side (or bottom side, when you hold it). Because when you play you sometimes touch it and change the volume.
    6. The hook I made from wood and glue to wings. If I build now, I will make wings from hardwood and wings and the hook will be one part for strength.
    I think I have to rewrite this article, because it don't have fool list of materials. And I want add part where I write what I make wrong.

    ahhh!!! so the top piece comes with the rear bridge! I can't believe how many of these sellers on aliexpress fail to say that. thanks! Your article is written just fine, but you need just some more details and close-up pictures like the top and then attachments specifically the headless assembly. they are very new and unusual and while I've built guitars before, they were with traditional tuning pegs, so documenting this new design would be great. I also have never used a truss rod so that detail in your build would help me.
