the smell of the super glue was so strong so I was using a breathing mask







btw I spoke shave the neck and I reduce its thickness, the was super thick

so I was adding the epoxy to fill the wood grain and to level the brushed stain, layer by layer and sanding between them after drying,

my friend didn't like any from the decal waterslide rossette , and I dont have the skills to add a real rosette , so i started to Photoshop the conde hermanos rosette !!

so after wet sanding the epoxy I sprayed the NC sealer then I hand applied the NC lacquer,

I did all that in open area because the NC is very inflammable

It's good fun to hack a cheap guitar. I have done it to several electrics and you can learn a lot in the process. Keep us posted.



SephardRick -> RE: Yamaha C40 - extreme make over - guitar edition (Jan. 5 2015 19:01:38)

Yeah! Like the boss just said. Most us have experimented and refinished factory made guitars to some extent...

I really admire your guts. You are doing what most of us players only think about doing.

I say damn the torpedo and run...Just publish the details both good and bad.



Haithamflamenco -> RE: Yamaha C40 - extreme make over - guitar edition (Jan. 7 2015 6:13:46)

ole amigos, thanks,

at this stage I was facing the difficulties in finishing,

I was using brushing lacquer (Minwax clear brushing lecqure ) but it was think and heavy to brush, so I thinned it with NC thinner and didn't really brush it but wipe it,

using the superglue as a grain filler was not a good idea, its super glue is very thin you need maybe 20 superglue to file the back only, but it works good as sealer for the lacquer,

so I was wiping the thinned lacquer and leave it to dry and wet sanding between ,







I was working for long time on the finsihing, at the end I couldnt reach the glossy finsih I was looking for, I didnt have a buffer wheel so I was using my car polisher and dimond cut polish ,

I printed the rossete on a glosse self adhsive paper and I stick it on the top and I will cover later with the golpe

Haithamflamenco -> RE: Yamaha C40 - extreme make over - guitar edition (Jan. 7 2015 6:31:04)

I installed the golpe over the top and the top of the printed rossete,

and installed a golden machine

Haithamflamenco -> RE: Yamaha C40 - extreme make over - guitar edition (Jan. 7 2015 8:17:17)

more photos,

I apologise I didnt take a good photo afte I finsih the guitar,







below is the before and after photo




ok,

what I did to the guitar is:

1.stripping the poly paint and refinsih the guitar with differnt color and NC lecque
2. modfy the head stock look like conde hermanos medi luna.
3. lower the action by lowering the bone saddel and the bridge.
4. reduce the thickness of the neck.
5.open a sound port.
6. add golpe.
7. stick a conde hermanos rose type rossete.
8. replace the machine head tunners.
9. add flamenco strings medium/hard
10. frets leveling.

difficulties:

1. removing the original finshin was the worst, its very hard and there is a thick layer ander the stain , Ibilive its a sealer, the paint remover couldnt remove it.
2. I faild to cut the sound port in oval shap like some flamenco guitar I dont want to mention its name [:D], so I end up with an oversize soundport.
3. filling the open grain was a night mare, using superglue is a filler is bad idea, but the super is medium is good.
4. couldnt reach the shiny glossy finsih, lag to tools and machines

Ricardo -> RE: Yamaha C40 - extreme make over - guitar edition (Jan. 7 2015 17:18:23)

I always thought the C40 sounded darn good in the music store. This one sounds like a good conde! [:D]



SephardRick -> RE: Yamaha C40 - extreme make over - guitar edition (Jan. 7 2015 21:44:38)

So, Mr. H...

Tell me more about the whale hole (sound port) that you added. Are you pleased with the sound when practicing alone? Do you hear a difference?



Flamingrae -> RE: Yamaha C40 - extreme make over - guitar edition (Jan. 7 2015 23:38:43)

Wow, you have done loads and if this is your first go at this, you have done well.
I eventually got around to doing my Alhambra. Different approach to what you have done but some of the same difficulties so you can check these off for "your next project"

Removal of laquer - heat gun not paint stripper
Removal of back and about 10/12mm of the rib height. (It was a classical)
Lighten and re-shape internal bracing on the front and back.
Once back is back on, route and install proper bindings.
Re shape bridge - lower tie block, convert to 12 holes, add bone fittings and saddle.
Re shape heel then French polish the body.

I might have done more but when I discovered that the wood (if you can call it that) was laminate, I held fire.
Still pleased I did this and I'm sure you must notice a difference with your guitar. Loved the solution to the conde rosette - might have to watch copyright on that though.

yes rick, as I said , it was my friend requested to make an oval shape, but I failed to make oval using a wring saw, I know is big, usually I make the sound port for this fully plywood c40 guitar about 2.5inch diameter , and its really making a different

here a video for a Yamaha c40 before the sound port

after the sound port

the actual guitar in this post is fine with this big hole, but know I am considering to make a sliding door for it, so he can adjust the size of the port.

BTW I saw half section cut classical guitar in guitar shop in bahrain, Manuel rodregiz and still sounded good ,



[:D]

this is the usual size i cut

What a novel idea. An adjustable sound port to fine tune the port volume.

Thanks for sharing your results! I can't tell you how many times I wanted experiment with sound ports, but never got around to it.

this is a good post i have a yamaha cg122 these are solid top classical guitars they come in spruce top or cedar they have a super lightweight body lighter than any other yamaha classical model i have seen with a matt finnish and a standard 3mm at the 12th fret the bridge can be taken down a huge amount but i have only adjusted the saddle so far the string height to the body of the guitar at the bridge could go as low at 1 cm without any problem. for a guitar i already have this will be a good flamenco conversion i did plan to buy a proper flamenco but were i stay in a huge city there are no proper examples of a good cheap flamenco guitar.


go for it and enjoy[;)]



fyr4efect -> RE: Yamaha C40 - extreme make over - guitar edition (Apr. 5 2016 1:44:32)

Wow. What a project !
Doing something similar to a Yam SF 172. Like you I figured "what the hell"
Sanded it today, mixed the FP crystals with alcohol today and will start FP tomorrow.
Didn't know the rosette was a decal until the sander took it right off.
Kinda like putting a chandelier in a mobile home but its fun.
Been years since I did any FP.
The rosette decal cost 5.95.
Cheers



Erixon -> RE: Yamaha C40 - extreme make over - guitar edition (Apr. 9 2016 12:42:46)

Same here Ricardo, I used to own a CG130A back in late '90 and the guitar sounded like a crystal. Well balanced instrument. I can't believe I have let that guitar slip out of my hands... I ended up having to sell the guitar...



Erixon -> RE: Yamaha C40 - extreme make over - guitar edition (Apr. 9 2016 13:06:20)

Love your makeover project Haitham, but I could use a soundbite, how it actually sounds. Can you upload a soundsample so I could hear what you have done?
I have done a similar "makeover/repair/reconstruction", although with a high end guitar - I took a big risk - all or nothing - with a vintage andalusian blanca. I have to say the process was a bit longer, I had to struggle with lack of time and finances, but at the end it has paid off very well. With one difference, I left my J.L.Bellido as it was and did not carve medialuna semi-circle into its head, lol :)
So I understand why people do such makeovers, specially when there is nothing to loose but only gain and during the process they learn a whole lot about the construction and see how things work.
Cheers mate.
