It's another Menards Special. bliss

Mahogany back and sides, multi-piece WRC top, rosewood fretboard, not yet pictured. Ebony bridge. Ebony binding.

Body shape is small jumbo, or as close as I could get drawing it from pictures.

Sweet. I'll be interested to see how you like the cedar top. Scale length? How did you brace it and how do you intend to tune it? (I'm a bit of a 12 string junkie)

I've used the same cedar on a few other guitars, and have liked the results so far. We'll see how it does with 12 strings on it.

The scale length is 25.5" I used standard X bracing on it, but made the braces about 25% taller and wider than I do for 6 strings.

I'm not sure yet how I'll be tuning it. I'm hoping it will do well with standard as well as lower tunings. We shall see. :)

Looking good Phillip. I'm building an L-00 12 string right now (first 12 string) with a cedar top and am planning to tune it to standard. I may try C# tuning just to see what the Leadbelly fuss is about, but will likely stay at standard as I'm not real good at transposing when playing with others.

I have a 1987 Takamine with cedar top that has always been strung at standard pitch and has never had any issues with action, bridge lifting etc. I realize that it is likely somewhat overbuilt, but it does sound very good.

Looks very cool. Like it alot.

A picture of the bracing would be great if you have.

Sorry, I don't think I took a picture of the inside.

Hi Phil,

I have a Suzuki slothead 12 string with a cedar top that I have had since new in about 1982 and it sounds great and has held up very well. The bridge did lift once but i just glued it back down and it has been fine ever since.

This one will have a slotted head too. Seems like it would save a lot on weight.

One of these days I'm gonna get some spruce from you. :) Do you sell violin wedges?

That is looking awesome Phil. You will really like the slothead (I do!). I have a few violin wedges here but almsot always have archtop mandolin sets which are great for violins as well except that they are slab cut and sawn already.

Thanks
Shane

Yup, they are indeed quartersawn. Most of my processing of these go to Roger Siminoff who has been my longest and best mandolin set customer.

I just glued one up last night with fish glue for a violin I am going to make for my son.

Well, then, as soon as I have some disposable $, I'll order a few sets. I want to make a couple violins, and a mandolin or two.

Looking great Phil!
I really like the proportions of the upper bout.
Interesting that you ran the herringbone the same direction all the way around - I like it!
I can't say as I am familiar with too many slot-head 12-strings - your headstock looks great!

That is one really nice guitar you are turning out although I have one concern and that is the design of the bridge. To me the bridge pin holes are a bit too close to the saddle slot and the countersunk edge at the upper base end is almost touching the slot. Would this not put quite a serious break angle on the string?

Post subject:  Re: Working on my second 12 string

Well, I actually finished this one several weeks ago, but didn't take pictures until now. I got lazy with the finish and left it satin. I actually like it, though most customers probably are more used to high gloss. But this one's for me to keep. :)

I think you have a good point. It's mostly just a problem with the low E course, but I will be changing the bridge design on the next one.

Looks fantastic Phillip. I'm working on a mahogany/cedar 000 12 string right now, so definitely enjoy seeing similar ventures.

just curious: what type of tuning gears are those, and how long is the head stock? :P

These are "Golden Age Restoration" tuners from Stew-Mac. They're a whole lot lighter than regular tuning machines. This whole guitar weighs about 4 pounds.

The headstock is about 8" long, maybe a bit more.

I didn't work from plans, but plans are available somewhere I'm sure. :)
