burnish. no mess.
The shaving that you'll need to glue into the gap to get the right grain orientation to be invisible will need to be a cut across end-grain rather than along an edge. That's not always easy to get a shaving of the right thickness with a hand plane. I'd try cutting some on the TS (at a 45) with the blade not cutting all the way through so it remains attached where you can find it.

I didn't have any shellac so I just used glue and it looks like it is doing the job. I use a monofilament fishing line to work it down into the opening as far as I could and then built a little up on top.
So we will see tomorrow night how it sands out.
Thanks to everyone for the help.
There is another solution. It's to shellac, but not the liquid kind. Rockler sells "burn in sticks". Furniture repairmen use them in a wide variety of colors to hide blemishes and repairs. It could work pretty well in this application.
One reason for not using Titebond on walnut is the very reason that they sell a DARK version of Titebond. The whiter glues can show up and emphasize your fix rather than hiding it. Thick orange shellac with sawdust in it might make a darker line than you want and blonde shellac might be too light.
Shellac as a binding agent is a very old timey fix. One could use hide glue to achieve the same thing. Both are the stuff that furniture makers had around all the time. That's why they use them. That and finishes stick to shellac much better than to Titebond.
Just a couple of thoughts.

Hello,
Dean's got it.
Google "shellac sticks".
They're made just for this purpose.
A person with a steady hand & a "good" color eye can make scratchs &/or cracks disappear using shellac sticks.
Practice a lot with them before you actually try it out though. They're a bit tricky , plus you have to have a knack for using them.
I have a pretty fair "color eye", but I'm a total bumbler with shellac sticks.
I've known some people though that could work sheer majic with them.

Gary,
I went through my "Finishing folder" since I usually print and save information like this and was able to find it. It was posted on one of the other WW forums but the thread has expired. It says the following: "mix a little shellac with some fine dust flour of identical species from your ROS bag. Do not use sawdust. Make a paste and apply with a plastic spatula. Sand and repeat is necessary. This works, but this is even better. Use Titebond liquid hide glue instead of shellac. This is the best I've ever found for filling grain pores and hairline pores and voids. Use epoxy and wood flour for larger voids, tearouts, and defects."
This was another reply in the same thread: "Clear shellac would be better, but amber will work too. These instructions are from a professional finisher. Sand a piece of scrap from the project with 120 or 150 grit sandpaper. Dump the dust into a paper bowl. In a 2nd paper bowl I'll pour in the pre-mixed shellac (you can mix your own #2 cut). About 1/8" will do since you can always add more later. You can always fix it if it's too dry, but if it's too wet, you'll have to start over. With rubber gloves on, take the sawdust in the opposite bowl with your hand and put it in the bowl and start mixing with your hand. If it's too thin, add more sawdust... too dry, add shellac. You want to have a meatball type of texture on the filler ball. Do not try to dump in a pile of sawdust and mix because it will dry out too fast. Use pinches of sawdust and keep adding until you get to that meatball texture or until it holds fairly well a ball shape.
Now this is where you want to work pretty fast. When the alcohol dries, your "meatball" will start to harden and crumple. Know where you're going to fill and fill ASAP. Let it be proud of the surface. When t dries, you can sand it down and it will blend in. When you're finished, knock off any clumps that might be on the piece and let it sit overnight. The next day sand it starting at 120 or 150 grit and work your way up to the finish sanding grit. The key to this method is fine dust (120 or 150 grit) - no lower or higher and mixing pinches at a time. The only drawback to this method is you have to work pretty quick before alcohol evaporates."
I just read about "fixing" miters in one of the magazines. Perhaps this is the rough way to fix this, but one option is to joint the inside edge of the piece. Doing so effectively lengthens the piece eliminating any gaps at the mitered corners. The tradeoff is that this piece is then just a tad skinnier than the rest. But, depending on what you plan to do with the outside edge, some subtle sanding can eliminate what would likely be less than a 1/16 difference between that piece and the two adjoining it.
I wonder if either has distinct advantages to mix with sawdust for patching: shellac or glue?
Been a real good thread....thanks for all the shellac and hide glue tips.

When I got my clock finished, I had a couple of less than perfect miters. After finishing, I rubbed it with dark wax. The wax filled in some of the little gaps, and also gave a slight bit of toning there and in some of the corners where I couldn't get it all rubbed off. Any gaps that were still there were almost un-noticable.
