Last year i made a carbon fibre violin ,
I started out  by drawing a violin on paper ,  working out the curve heights , plotting the lot on paper ,

Once i had my plans drawn it was time to start making moulds , the violin plate moulds started as block of plaster , that i routed out and fine carved to produce a "plug" , the 1st mould was taken off that  , then fine finishing the top and bottom plate  mould  took about 1 month , and i  still had a lot of fibreglass moulds to make , rib mould , neck mould ,   finger board mould, they all take time. ,
To have a Shop Bot would be a huge help with the mould making  , change the shape slightly on the CAD drawings ,rerun CAM , and watch the Shop Bot produce its magic on HDPE ( only a dream )., using a Shop Bot to draw perf lines , and trim the carbon fibre , i wish i could afford one .

The first plates i made from carbon fibre were way to stiff , "tap tone's " told me it was better used as a brass bell than a violin , after producing about 10 violin plates i was getting into the ball park of tone , a combination of different materials  , laid down in different thicknesses in different areas produced a violin front and back plate i was happy with .

I used the infusion method of carbon fibre making , were you lay all your layers up dry and vacuum bag it , once the vacuum is over 25hg (-12psi) you open the tap to the resin , and the vacuum pulls the resin into the carbon fibre fabric , the laying up of the rib mould took me 5 hours each side to get the fabric to sit in the right position , very fiddly ( pardon the pun) .

The gluing jig was made from MDF with 10mm cup heads sticking through , designed to allow side ways positioning of the rib and neck parts , and the holding down clamps for the top and bottom , the centre part  of the jig was removed to glue the top on, with the 4 hour set time of the resin ,its important to keep it all firmly heard in position. 

The cutting and shaping of the f holes is another reason they call them fiddles , carbon fibre is a bugger to cut , found that if you submerge the carbon fibre in water and use a Flexi Drive bit holder on a Dremmel, it keeps every thing cold , and produces no dust , just ware a rain coat 

After a final coat of clear and a polish it was ready to string up and hand over  too some who who could play it , ive had grate feed back and a few offers for this violin and at the moment are remoulding for violin 2 ,working on the  2nd set of plans  now ,drawing them up on a  low budget Cad , AutoCAD would be a big  leap for me and  used with a Shop Bot would speed up design changes 100 fold , and allow me to produce Cello's and Violas .

All up it took me 10 months of Sundays , from the time i decided to start to finished product , i had never made a violin before , and my carbon fibre skills were below basic , it was a huge learning curve but between the info on the net and getting your hands dirty and " givin it a go" , anything is possible

Dont forget to vote for this ,

Beautiful, and a first try ! How many layers of carbon fiber did you use for the top plate? what is the final thickness before resin and after resin? thanks

i know you did it but it looks impossible

That is the coolest thing I have ever seen. The violin isnt the most exciting instrument the world has ever seen, but you have made this one super cool.

Truly an amazing instructable (sp LOL) be proud of your contribution!

Congratulations! Your perseverance must border on the obsessive. I don't even play violin anymore, but I'd buy one of these.
great job! i play the violin and i totally feel like playing the one you made....its so cool?

Found this carbon fiber violin maker who has managed to keep the scroll work on the end of the neck. Pretty rad. http://www.kickstarter.com/projects/156894760/violin-carbon-fiber-engineering-and-tooling

lol , kickback fund raising for digitizing an existing violin and making aluminium molds , great idea , i went down the track of buying a CNC machine and making a furnace , so i can sand cast aluminium molds , the machine and polish the surface ( 36hours to get too mirror finish ) , im on my 4th CAD drawn violin plans now

CNC ,with CAD and aluminium / diesel furnace set me back , $4000( a lot of work and learning curve ) , lol , less than 1/2 of what hes asking for 1 one set of molds to be made ?
Aussie. Thanks for the great write up. Would you be availabke by email or chat? i'd like to pick your brain on a project i have and it's too lenghty to write here. My email is javier at coachcall dot net
AussieCFviolin (author)  AussieCFviolin2 years ago
the advantage of owning your own CNC is that the inside of plates can be ground down to perfect thickness , and the out line and F holes cut with out any hands on time
Holy.. If I had a violin like this I'd definitely start playing xD
Amazing work!!
Should have made the bridge piece out of carbon fibre though. Would have looked better. But maybe there is a reason it's wood?

really nice work,
a friend of mine made a copy of "Lucille" the famous guitar, but he played only one time with it in concert and got shocked with electricity, so now it is only decorating his rest room... :(

Who doesn't think carbon fiber is awesome? Anyone?
it is, but it is also really cancerous !

Marvelous! =~~)
Congratulations man! You rock!

Will it work without the vacuum bagging process?

What kind of carbon fibre cloth did you use?
AussieCFviolin (author)  vnams2 years ago
2Ktwill , 12kUni , 6kuni , 2kUni , all sorts
A carbon fiber violin by the brand Luis and Clark was featured in WIRED magazine for $5539!
Aussie I am working on a project where the connecting rod of an engine will be subjected to very powerful magnetic fields. Powerful enough that the eddy currents in a metal connecting rod might generate to much heat. Could a connecting be made out of carbon fiber?
AussieCFviolin (author)  neferkamichael2 years ago
Carbon conducts electricity , so will still have eddy currents , probably worse and more uncontrollable than aluminum / steel
Maybe a Kevlar blend would be better ?
The question is.... does it sound good? I play violin.

you could use sketchup a google cad program. it is free and has a large following. they have an extensive library of drawings, possibly already have a violin or viola to start from. you did a great job! thanks for your instructable!!!
AussieCFviolin (author)  crasch482 years ago
no i dont think you could draw one in google sketch
I'm going to have to agree with AussieCFviolin. I've been using sketchup for 5 years now, have been able to master something as difficult as the attached photo, but the only thing I can figure the program doing with ease would be drawing the several circles to create the paper violin shape.

Wonderful work sir. Thank you for sharing your instructable. :)
Apologies, the photo would not attach. Here is a direct link:

im using turboCADpro to draw them , drawing up my 4th molds this week
i only had a short play with google sketch , with out the type in edit boxes on the bottom most CADs have , it would be hard to position any thing accurately

I was the owner of a small, yet successful, carbon fiber parts manufacturing company in the automotive industry, and I must say this violin is EXCELLENT! Very very nice work my friend! Wow.

I haven't done much with CAD, but from what I have... that seems really difficult. Great Job

Impressed with the project and responses, however the spelling skills are atrocious . Bought a book years ago because of an article in mechanical engineering. The book was a specially designed book of info templates etc. by 2 brothers named Doerr.
stickbf stickbf3 years ago
Actually I've bought many books but I actually bought 2 of the Doerr violin books and donated one to the Carnegie Library of PPittsburgh music Department.

thanks for the complements , and wow you bought a book once ????

Congrats on being a finalist, and good luck!
I would love to hear it played...
I second (or as other have also requested, 5th or 6th) this request. A video of you playing it?
AussieCFviolin (author)  imartens3 years ago
lol i cant play
ok ok , ill dig it out of the shed and restring it , tune it up and play it to the best of my ability , 4 open string notes , i can manage that , the bugs are a bit loud now , but it would be better than traffic during the day , im on to it
Don't do that... Get someone who can play WELL to play it. The violin is beautiful but if the sound quality isn't right then there is no since building it.
