Finishing up gluing the braces onto the top of my OM 28 1931 for my first guitar build. ( Kit from John Hall)
The braces supplied in the kit are scalloped.
That said, they still seem very bulky and I believe need trimming.
Obviously, there is a whole magic art to this and is well beyond my experience level at this point.
At this point, I just need some basic suggestions on how best to trim them for typical performance.
If anyone has any pictures of a typical OM top with trimmed scalloped bracing it would sure help me out.

Thanks

This might help. I found it online someplace.

The PDF is very helpful.

This is an OM I did 11 years for a guy in England. It's a redwood top. He loved how it sounds.

How wide and high are they? Bottom of the curve on the scallops? That sure is pretty!

Hmmm I make the X and tone braces 5/16th wide and start with 1/2" tall. Scallops generally go down to about 3/16th from the surface of the top.

Very nice shaping on those braces.
I will try to emulate this as best I can.

Thanks

Here's a fun-to-watch video of how a luthier at Martin shapes scalloped braces - all in less than 4 minutes:

Amazing. I just found that Martin video myself.
I copied the link and signed into the forum to post it for others to see and you beat me to it.
Looks like this guy has done it before :)
I'll try to do the same thing.... only it will take half a day.

He sure has a wicked sharp chisel!
