Ah, darn it Mr Birko, ya beat me to it. My thoughts exactly. Very subtle bevel. OP, you just entered the bevel zone. And I'm betting with a bit of googling I can find a classical bevel

Waddy, excuse me. I did not see it was you in the opening post. However, bevel or wide purfling will work. Checkout http://petrosguitarshop.com. Those are beautiful things that can make up for the problem you have.

As I see it, the issue is less the top and more the side. If you can't find the piece that was torn out, perhaps you can add an artistic element to that area and make lemonade from a lemon? Perhaps a little piece of "vine" with leaves coming out from under the bindings or something.
This happened to me on my last OM back, and was an easy fix by adding herringbone to it, but fortunately the side didn't blow out badly and the piece was found.
I think using the off-cut bindings is your best bet for as clean a fix as possible though.

Sorry this happened!

So, what happened? Did the part your bearing was riding blowout?

This looks like a climb cut issue. Hope you find the part.

I went through the vacuum bag, no long pieces. I have one I found but it is missing too much to fit perfectly. I think I'm going to have to splice in a piece from the off-cut binding that best matches the color and grain orientation. Looking at it last night, it's going to be tricky to get a good match, but may not look bad if run all the way to the tail graft. If all I have is a dark line, it may not show so much. This wood has strange grain and spots all over.

As for the bevel, it might be a good idea, but probably not in this case. This guitar is going to a CG student at Appalachian State Univ, in the guitar program there. Not sure how it would be received by the Professor, who recommended my guitars. As a matter of fact, he gave his slot to this student since he needed a guitar more than the Prof.!

My fear of taking it to the end graph is that you would introduce a straight line cutting across some of the existing grain lines. The eye is so good at seeing straight lines or changes that occur on a straight line that it may make the patch more noticeable.

Looking at the side wood, a little suitable color dye/stain could perhaps be brushed across the joint in places "strategically" to break up any straight line??

The name catgut is confusing. There are two explanations for the mix up.

Catgut is an abbreviation of the word cattle gut. Gut strings are made from sheep or goat intestines, in the past even from horse, mule or donkey intestines.

Otherwise it could be from the word kitgut or kitstring. Kit meant fiddle, not kitten.

Once you get your new binding cutter, I would consider something like Purflex.

It comes in various widths and it would look very nice.

If you do have enough side material left to put in a patch it could work out. However, if doing this make sure that you check for run-out in that side material and ensure that the patch has the run-out oriented the same way. I had a small router mishap in a claro walnut side that had some run-out. I managed to patch it pretty well, but got the run-out in the patch running the opposite direction from the rest. So, my patch looks darker than the surrounding wood when viewed from one angle, and lighter when seen from the opposite direction. It is not a disaster - but I didn't pick up on it until the finish went on.

I'm with Haans, unless you (and your customer) are really really ok with a really wide purf.

Without hesitation I'd at least replace the sound board.

I want to thank you all for the suggestions and the empathy. I finally decided if I'm going to fix it I'd better get on with it. First, I cleaned up the blown out area in the side. Image

Next I found the best matching, in my opinion, piece of binding. When I cleaned, my goal was to get the slope as near a straight line as possible. I cut the piece the right length then tapered off the section that meets the slope. Next I bent it to fit, nearly. Then I played with it scraping spots and sections and beveling the butting edge. And came up with this. Image
Next I fiddled more and finally got this. It's just taped in place, but I think it'll be OK. Image

So, what does anyone think?

My plan is to glue it in with HHG.

It looks like it'll be invisible in the upper part of the photo. Is the dark line from the lower piece of tape to about half way up to the next piece of tape a gap that will close, or is it a shadow from that section of the binding being slightly recessed below the level of the side?

It sure looks like it can work.

So, I can understand, you are filling the wide are with matching side wood, then plan to rerout?

Looks real convincing to me, Waddy. The joint is following the sides natural grain direction. After you've glued up scraped/sanded, I'll guess you will pore fill. Would probably have to point to it to for it to be seen. And the top?
Will a wide purfling scheme work? How deep does the errant cut measure?

It may not be perfect, but I'm hoping it will not show after finishing. I'm fairly happy with it. Actually the graft is thicker than the side a little. After gluing, I'll have to sand it back to level. I think I can get away with adding a WBWB to fill the wider purfling scheme. It will actually match the rosette then.

Making lemonade from a lemon. Sweet. (Phew!)

Looks like a good solution is on its way! I bet it will come out pretty good.

Just curious from a luthier perspective - are you going to deliver this guitar as an order, and if so, how are you thinking about handling it? I've had issues somewhat like this in repairs (where the guitars originate from the client) and I think it is a good thing to discuss (at least I appreciate the insights!)
