While Brad is off making Serious Lifetime Commitments I update y'all for a few days. I am binding this guitar right now, and here is the first quarter going on:
 The red in the top purfling matches the rosette detail you can see earlier in the thread.

Later today I'll have a picture showing how close I got this to being the miter I imagine. Always a bit of a gamble!

The miter DOES meet my expectations!
 And, compare this picture to the similar one toward the top of the page w/o the binding. To me the difference is very dramatic!

I am current wrapping on my binding with mason's cord which comes from the hardware store. It is 5/32" if memory serves, and has just the right flexibility and stretch characteristics. Deeper in the coil there is some cotton clothesline which also works and is easier on the hands, though it doesn't do as well on the tighter areas such as I am working in the last pic. The method is my adaptation of traditional Spanish techniques, and Jute cord was the binding rope of their choice. My favorite that I have used was u s government issue parachute cord but I have no idea where to get that and mine passed quite some time ago.

This last inch and a bit can hardest part as there is nowhere further to go to take up slack; the buck stops here, as it were. Went well this time, though. This photo shows the medulary fleck in my bespoke maple purflings nicely, I think.
 Actually, Chris, I am wrapping 7x in a cutaway situation like this one. Once for each side (4x), once for each cutaway (2x), and once (1x) for the little piece most recently demonstrated. I still have the graft to go.

Miters? What miters?
Wow. Those are some clean miters Bruce! How do you cut them? Chisel? Scalpel? Razor blade? Laser beam? Nice work, but you knew that.

Thank you Joel and Tony, it's nice to know anyone is looking. I hope Brad is able to find a moment as well! He has every excuse if he can't, of course.
There no particular magic to cutting accurate miters, Tony, it's a matter of having the right tools and a lot of practice. I am using a 2 mm chisel for the fixed side of the miters, which is just the right width at a 45 degree angle to span my purfling. At the loose end I use a seriously sharp 3/4" chisel and wing it. That's where the practice comes in, it wasn't always so easy or so accurate. It is a rare guitar the last 10 years that has any need of filler/repair (besides pore filler) at all whatsoever! That is a hard-won brag. Here the graft, which also seems to have come out nicely:

I can get the miters OK but my first few attempts were like an Earl Scheib paint job: Looked great from a distance, but upon closer inspection, there was something amiss.
I would get 4 out of 4 perfect but when scraping the purfling flush, one miter would end up slightly off. I have since realized what I was doing wrong and corrected my technique. Here is a pic of an all koa OM I did really well. It was my 4th guitar. Too bad I dont have a closer pic.  One day I will do killer clean miters like that all of the time. One day.
