Regarding boiling sides: I actually did a dulcimer and a baritone uke this way many years ago, following Irving Sloane's book. It can work if the wood is very straight grained and well quartered, but even then you'll get some cupping that has to be sanded out. Your wood looks very figured. I think it would bend very unevenly if boiled.

I strongly recommend rigging up a hot pipe. Hot pipes really work better than boiling, because they tend to iron the wood flat crosswise as you are bending it. The pipe method lets you avoid a lot of unnecessary work scraping the sides.

Like Clinchriver says - practice on scrap first.

Don't worry too much about bending sides. This particular part of guitarmaking tends to intimidate people, but it's really not that difficult. Just go slow and keep fussing with them until they fit the outline. Other aspects of building are actually harder to do well: like binding and finishing.

idunno never do before,.. so confusing to me... duh but thank you for your all to support us,... and this morning I'll post my rossette... bliss

I design this rossette for simple because of the small guitar,.. I use material: teak wood and the circle line rosewood
And I matching the line with the pickguard from rambutan wood veneer (.06) I love this wood :lol:

Carving?? That's a pretty thick back! Can't say I've seen this sort of approach on an acoustics before. What is the thinking behind it?

behind this I feel so much to build an Archtop, and this little guitar I want to make a more bass louder (just my opinion), and I try to make the Back a little arch model like archtop (it's 0.6"= 1.5cm) but what you think about that?
I said my little guitar is ARCHBACK wow7-eyes (NOT ARCHTOP) :lol:

I have no idea how this will effect the tone of the guitar. I do like strange new ideas though. I'm super excited to see how this turns out for you. How thick will the back be? I'm guessing you will have it pretty thin? Anyhow it will be very unique, which is always good IMO.

Robert Benedetto carved Back plate for 3/16" in the middle plate for an Archtop, and the Plan of this guitar approx. .13" arch (3.3mm) so I'll try thinner about .12" (3mm) or .11" (2.79mm) beehive for making bigger bass oops_sign

Gibson made at least a couple models of flat top guitar with an arched back. The Gibson Gospel comes to mind. It was very good sounding. A friend of mine had one. Guild also made at least one model with an arched back.

Not sure you'll get more bass, but an arched back seems to add a slight reverberant quality to the sound. Bass will depend more on how lightly built the top is.

HI,... i'm back,... bliss
Thank's God for Your time for me to continue my guitar building, and thank's to friend's and OLF senior's for your suggestions... :D

This is Back part, at the beginning I've confused for carving this part, three times that glue joint was loose gaah , I use electric sander, that hot friction the cause,.. so I remember that carving must use hand scrapping and I succeed with this metode pizza , I'm happy although not yet finished :D :D
:mrgreen: that wood very hard... wow7-eyes wow7-eyes

I'm back,... pizza
The soundboard almost ready just for chiseling, so the Back board, but I need your suggest: for the Arch Back is that need wood bracing?, I ever read that arch back no need bracing,... and I feel that's very solid .
Now I'm preparing wood for kerfed linings, and the Side is ready for bending... bliss
thanks

Love the bamboo go-bars :) Looks like a nice brace pattern too. Be sure and cap that X, though!

As for the back, it shouldn't need any bracing. Violin family instruments don't have any, and they have a soundpost pressing on it. So a guitar should definitely be fine.

Hope you finish on time for the competition! But if not, it'll still be a sweet guitar. Those first few notes are a the real prize, after all :D
