Turning Paper Bags Into An Acoustic Guitar - No Epoxy Resin

I #recycled some of my old #paperbag into a #guitar . This video is an experimental project, using paper bags and glue (No Epoxy Resin) and with normal guitar materials like Truss Rod, Fret Wires, Tuning Pegs, Bridge and Nut. Hope you enjoy watching

[@rauschguitars]

It held up surprisingly well, I was totally expecting it to implode! 😂

[@GitaraMaker]

I was also expecting that. I'm really afraid it will break first before I could play it 😆

[@kaceyvibes]

This is a really creative and interesting concept and project, great job! You clearly put a lot of time and effort into it and even if it were just for looks or the video, it would be a win, but the fact that it didn't tear itself apart under steel string tension is a triumph. Thanks for all your work that went into experimenting and sharing with us

[@hannuhanhi183]

What you have created is basically MDF.

[@Snedesk]

A high quality pasteboard guitar?

[@blenderbenderguy]

Impressive build and wonderful editing. Thanks for your efforts!

[@fishnoggin5319]

maybe try wheat flour paste for the glue? it's used all the time in bookinding. pla wood glue is meant to be flexible, which could be contributing to the issue. i'm gonna be trying this myself anyway lol

[@malcolmporter8158]

Probably could've used nylon strings. I'm sure this project was time-consuming. I'd like to make a snare drum out of newspapers. Not really to play but kind of a novelty.

[@GitaraMaker]

Maybe you can glue newspaper on an existing snare drum and paint a finish over it. That's cool

[@malcolmporter8158]

@@GitaraMaker that is a cool idea.

I want a paper mache Giant Doublebass!!

[@guillaumeabadie7178]

Hi I'm about to finish a les paul guitare out of card board. For that project, I used artway greyboard with wood glue. Maybe your guitare doesn't sonde great but there is no one else like in the world!

[@rafzan]

This is amazing! Paper fibers, just like wood, also have fiber direction. When stacking, maybe you would benefit from the strength of arranging layers like plywood. To figure out direction, just fold, crease and unfold the paper and you will see one of them will break and "splinter" the fibers. The smooth one is "with the grain" (works best with thick paper). Cheers! Thanks for the vid!

[@backpages1]

Excellent effort sir!

[@morrelljw]

Very impressive. Great build and video. 👍🏻👍🏻

[@GitaraMaker]

Thank you!

[@tctc8578]

Best up Cycling I’ve seen on KZbin! Great craftsmanship 🙏👍👏

Thank you! 😊

[@DUY1337GUITAR]

Try a build with longboard veneer, they come in many colors. Great build once again!

[@alexanderguestguitars1173]

Some genuinely good ideas there. I'm not sure how a paper laminate guitar glued up with PVA adhesive would hold up over time. There's a lot of moisture still trapped in the laminations from the adhesive, and when it eventually evaporates it could lead to warpage etc. Also PVA itself is not a very 'hard' adhesive and even when its cured (fully dried) it is quite soft and rubbery. I think your conclusion at the end that epoxy would be better for this type of construction is a good one. You could also look into urea formaldehyde glues, which are commonly used for veneering. They are water based (like PVA) but have a hardener in them, so they will cure properly (and go properly hard) even when pressed between waterproof membranes like you're using. That's why you needed to leave the laminated sheet to fully 'go off' in the sun with the PVA lay-up. Because the waterproof membranes that you used on the top and bottom didn't let the water vapour from the PVA evaporate and 'go off'. The other thing you could look into is using a Bagpress. This is just a rubber-ey plastic see-through bag that you link up to a vacuum press. When you've laid up your laminations you can just put them on a board of a similar size, then put the whole lot into the Bagpress bag, seal it up, and suck all the air out with the vacuum pump. The atmospheric pressure outside the bag will then cramp the laminations together. It's much less hassle, and produces a flatter result than cramping bars, cauls and cramps. Very innovative!

Richlite has proven that paper can be a replacement for wood. Their material is paper laminated with resin. They make and sell fingerboard blanks for guitars and basses and you can treat them like regular wood.

[@KenGlasser]

I'm very impressed. Not sure how much time you spent on this project but it was wonderful to watch the video. The guitar sounded pretty impressive to me (although as you noted you tuned 3 half steps down from standard tuning and then the guitar didn't stay in tune long once you started strumming). Thanks for letting us in on your project. It was a lot of fun to watch the video. If you ever go back and try epoxy resin I would definitely like to see & hear the results.

[@GitaraMaker]

Thank you! Will definitely do that in the future.

[@gelosoriano]

You never fail to amaze me with your ideas. 😮

[@GitaraMaker]

Yo! Thanks brother

[@Kesh_il_Lindo]

I'm happy everytime there's a new notification from your channel! Keep going please 🙏

Thank you! I'll try to upload as soon as I can.

Wonderful Idea to make a Guitar, the Sound is good...very,very nice.

[@GitaraMaker]

Thank you!

[@peterstephen1562]

I very much liked seeing the use of old guitar building techniques and new fresh designs. I checked your other builds also. Best wishes and growing strength to your bow. Old string instrument maker from New Zealand.

[@GitaraMaker]

Thank you! You have a beautiful country

[@dirkda2451]

Maybe instead of epoxy use part wood and part paper? Paper for the top back and sides something like that. I think the basic sound is good just lacking strength and stability very cool project hope do more👍

[@johngrant5749]

Well done and thanks for the video. Yes epoxy resin and vacuum bags.

[@BrunodeSouzaLino]

An alternative to making your own laminated fretboard would've been Richlite, which is laminated paper bonded with resin. You can buy fretboard blanks from them directly.

[@mariolafontaine5853]

What a journey!

[@twokool4skool129]

Interesting idea, but you should have laminated the neck vertically, not horizontally. Solid wood necks have a hard enough time not bowing. Laminating the way you did will ensure this guitar will become unplayable very quickly.

[@GitaraMaker]

Yes, I agree with you, and the pattern would look good that way.

[@iwayanpurwanata8934]

I wanna play this guitar under the rain😂

[@GitaraMaker]

Bernth should play this guitar underwater 😆

[@ezeriamoore]

This was awesome! Great idea! I think if you want to stay with PVA glue, maybe use vacuum bagging to compress your paper layers and add more layers.

[@MisterNiles]

" Paper or plastic?" "Can you not see my John Fahey t-shirt?"

Put a couple of speaker drivers on it and you'll probably have on helluva speaker.

Next time kapag solid na hahaha one time use lang 😆

[@meno3633]

will you be redoing this with epoxy? I mean... i love to experiment, love the fact that you went for it... appreciate the amazing effort you put into filming it... but i cant help but to wonder

[@GitaraMaker]

Yup, I'll do it in the future. I'll collect another batch of paper bags and probably do a different guitar design.

[@headrushindi]

I suspect the body may hold up well if cared for . However I will be willing to bet the Neck will warp rather quickly in time , due to the lower density and higher porosity of the material used.

[@Chimo0102]

It would be interesting to see how this guitar behaves but with nylon strings.

[@CrossGuitarWorks]

Imo wrong glue and laminatung method. Use urea formahylide, the neck angle can be made without cutting the headstock by laminating with an angle and also use vacuum bags to glue and impregnate the paper better. Wood is stiff but light not so flexible. Good luck x

[@johnmitchelljr]

Well done. Thanks.

[@tijnstarr]

Very cool 😮

[@Tom-Lahaye]

This paper with PVA glue is very strong in tension but sadly not stiff. That's because the fibers in paper are relatively short and in all directions in the flat plane. Wood has it's grain more oriented in one direction which is used to the advantage of the luthier. Paper drenched in CA glue would give a far more rigid board but I wouldn't recommend this doing indoors and without proper PPE as there will be an insane amount of cyanide fumes forming in this proces. It would also be very costly. But it's one of the most rigid hardening glues and soaks in paper very well.

[@takeawaybenji]

A general rule of thumb for composites is that the composite can not be stronger than the strongest component. Carbon fiber composites are so stiff because the carbon fiber is super strong in one direction. The pulp paper you're using is not particularly strong in any direction. You would probably do much better if you recycled textiles, since the individual fibers are much stronger than the paper. Silk would probably be the best.

[@takeawaybenji]

The role of the matrix (e.g. epoxy resin, glue, or whatever, portland cement, or whatever) is just to keep the fibers from moving around relative to each other.

[@inspectorcal]

fantastic model of a guitar but as you discovered it was a bit shit lol, but honestly what you get using resin,,,is a plastic guitar using whatever you want as a filler. great experiment and very unique.

[@johan96149]

Torres made a cardboard guitar that was recently restored to playable condition. It plays well. The layers for the neck should be at 90 degrees to what you did. What glue did you use? I will use thick craft paper, glued like paper mache with starch/wheat flour. Egg white?, hide glue?, superglue? Epoxy is heavy, for neck and fretboard only. Wooden neck, bracing and bridge? Bracing thinner with vertical layers. Finish with shellac inside, and outside. Bone saddle and nut. Nylon strings. Epoxy for fretboard, and same thickness spine of neck, to form T section. Thickness of neck, paper mache. Coat neck when totally dry with superglue. Finish with shellac.

[@GitaraMaker]

Wow I haven't heard of that guitar, I'll look into it. I did not use expensive materials on this guitar, cause I'm going for a recyclable low cost build since it's on an experimental stage. So I use Elmer's wood glue and and for the finishing sanding sealer. Also I learned a lot from this, with this guitar I can easily see tension points especially with the top brace design. Thanks for watching and leaving comment.

[@johan96149]

@@GitaraMaker Sanding sealer is is soft. Shellac is not expensive, and is totally natural. Methylated spirits will be cheap, but not the best finish. Casein glue is very flexible. Flour(paper mache) cheap and stiff, light, hard. A coat of egg white might strengthen it. Using cheap wood for the neck makes more sense. Laminate vertically with epoxy for stiffness. I must check what materials and methods Torres used. I see there are a lot of copies made.

[@Narrowboat.and.offgrid.living]

The same method low budget wood acoustic guitars are made layers of thin vaneer wood glued together

[@HenryAlvarez]

Astig nito boss! 👏👏👏

[@GitaraMaker]

Salamat!

[@moonboogien8908]

I know it would be an utter nightmare to work with, but maybe using superglue instead of wood glue for added rigidity after saturating the paper.... And if wood glue, maybe titebond 3? That stuff dries hard and is waterproof.

[@ast3663]

corrugated cardboard is not a good candidate for wood substitute..but very interesting build for sure

[@rodnyg7952]

the process you used basically made medium-density fiberboard, which is fine but is rather soft for its weight & doesn't resonate exceptionally well

[@neilmchardy9061]

It sounds unsurprisingly like a guitar, and kind of answers the whole question about specific materials.

[@dirkda2451]

Builds like this always remind me of when Taylor built one from a pallet just to prove that the construction is the most important thing not the specific materials

[@austitto8041]

If you used apoxy isntead of using wood glue,, it could have been a much stronger result... 👍

[@GitaraMaker]

Yes it will, and will last for a long time.

DON'T use a random offcut as a push-stick! B M Sculpures did that. He nearly lost his fingers. Cool video though, a great idea 😊

[@GitaraMaker]

Yeah I saw that, but I did not learn anything. Next time I'll stick a true push stick on my band saw so I can easily reach it. Thank you!

[@mrNobody100]

maybe nylon strings would fare better? impressive nonetheless...

If the former East Germans could make a car from paper why not someone else a guitar, cool idea very interesting to watch

Not yet, but the headstock straightens, and the top is getting pulled.

update ka bro after a month kung may pagbabago sa neck at bridge anu dahilan pala bat di matono sa standard?

[@GitaraMaker]

Di kinaya, dumederecho yung headstock, di stable sa standard tuning, 3 steps lower ok pa sya.

I DON'T UNDERSTAND: WHY WASTE SO MUCH TIME ON SOMETHING THAT IS DESTINED TO FAIL FROM THE START?? A REAL CARDBOARD GUITAR REALLY SOUNDS OUT OF INTONATION TO THE NTH POWER; LET'S SAY THAT IF THERE WERE A PARALLEL UNIVERSE WHERE BETTER GUITARS WOULD HAVE TO SOUND AND BE MADE OUT OF CARDBOARD AND SO MUCH, THIS GUITAR WOULD DEFINITELY BE A MARTIN OR A GIBSON CUSTOM SHOP!!
