Restoration of a 1931 Martin 00-17

If you have a string instrument of any kind that needs fixing, a mistake you made in building a new instrument that you need to "disappear," or a question about the ethics of altering an older instrument, ask here. Please note that it will be much easier for us to help you decide on the best repair method if you post some pictures of the problem.

Finally done with the clamp construction. Man, that was more work than I thought it would be.

So back to the replacement body. I glued the rest of the lower braces in the 25' radius form. Then I glued the upper braces in my half form that has a 60' radius for proper neck geometry. Finally, adding the splint on top of the X-brace joint (this is one of my few deviations from Martin methodology).

Nice work.
I really appreciate all the pictures.
I need your help. I can't possibly make all the mistakes myself!

I like the idea of the 60’ radius form for the headblock area braces. I usually sand the fingerboard attachment area flat to accomplish the same on my builds. I’m going to have to think awhile about your approach.

I did the math once and the 60' radius gave me the optimum neck angle.

Shaping the braces to as close of specs for this age, as I can.

Place my label on the popsicle brace. When viewed with a mirror it reads.....

The new wood on the inside of the guitar is way too bright so I toned it down with an alcohol stain. You can see the contrast of the back and un-toned top.

The clamps stained brown have pads that are angled for the waist and inline at the headlock.

I am sure that after looking at Bob's elegant clamping arrangement, this will look like clamp overkill, but that is sort of my credo.

Yeah, it looks like overkill. But, congratulations. Your work looks very nice. Were it not for your label, I’m not sure folks would know it was new work after it ages a few years.

Looks like you are coming right along with it. The clamps look good too.
Something I use to "age" wood when I need to is Potassium permanganate. Some one gave me a bottle of it, but I've heard you can get it from pool supply places. It is a strong oxidizer. Sometimes when working on old wood (instruments or furniture) and need to restore the patina because I sanded through the original surface I will first start by oxidizing the wood surface with KMNO4. It can also be used where you want to "age " new wood.

Interesting Clay. I used to use thousands of gallons of the stuff to clean up contaminants in groundwater and soil. It starts out as a dark purple liquid and then turns clear as it reacts with other organic substances. It can neutralize all kind of baddies out there.

I was given some lab grade crystals which I dissolve in water similar to what is listed here:

Notice the customer review. I wonder if that was Berkowitz.

Yeah, probably him. I will have to try the KMNO4 next time. Thanks Clay.

This is so excellent!
I also want to compliment the staining of your clamps to differentiate between the two types.

Sanded the body down and sprayed a couple of coats of vinyl sealer.
