So very nice! Keep up the good work!

Did a little more with the RO sander at the shop:

Refreshed myself with the Benedetto measurements and marked out the thickness for X-bracing:
Then realized it’s the back, not the top plate, so it should prolly get to 3/16”:
Drill press set up using 1/4” setup block:

Wow! So many things to take care of. My top is 6mm Jarrah wood, and there’s a big bridge support. Would you think I can do without bracing?

If you’ve got the supplies, time/patience, etc, there’s only one way to find out! - maybe do a fun little experiment?

I will tap and listen etc etc. Not sure how to tackle it yet. First guitar is not critical in hollow sound so that will be a bit of a test.

Went to the shop night before last and started the wood removal on the inside of the backplate.
Here’s my setup with back clamped in the caul. I cut some blocks to allow the clamps to screw down tight. I started with a 40grit flap disc on my angle grinder.
After 40grit before changing to 60grit:
Post-60grit and current status awaiting hand plane.

Yep, flap sander wheel is the way to go with the bulk of material removal. Before I built my CNC (and spent hundreds of hours learning how to use the stupid thing!) the flap sanding wheel was my best friend. To those woodworkers with the skills to use a gouge, tip of the hat to you. I’m in the “more power” camp.

Averaging 1/4” thickness on the caliper all around the plate (little thicker in some areas. Shadows also show it needs some finesse. Will work with hand plane and sander to get down closer to 3/16”.

Here's where she stands currently:
I think it'll probably be fastest to use the D'A plane to get closer to size as opposed to scraping at this point.

Current status after hitting it with the RO sander with 100grit:
Here you can see some remnant paths of Mother Nature's beasts in close-up that will likely remain as blemishes on this axe. I can't really risk trying to sand these out as it'll likely get too thin. I saw a cool series of images on Dan Koenntop's Intstagram page on how he cut one of these marks out and glued in a patch, but this piece of wood has too many to try and do that, me thinks. Being a tree from my childhood home, I don't really care too much that this won't be "perfect."
Next up, I'll drill the holes on the inside of the plate to get us great than 1/4", remove the bulk, and carve that down like the back. Being that this will be X-braced, the top thickness will be thicker than with parallel bracing I did on the last one.

I made a guitar body from beech a few years ago, found some worm holes that I filled with glue and dust. Half way through finishing I got a new hole, at least one of the little creatures was still in there
Not a happy moment…

I know there are also products you apply directly into the holes you find, via syringes. In fact, I'm pretty certain that even nitrocellulose laquer diluted with the appropriate thinner will be lethal for any insect larva living off your wood, but with this kind of DIY solution you'll probably want to make sure you've flooded the entire gallery system.

Over in Holland we successfully treated borers with petrol(gasoline). A lot and a total success. It’s quite easy to see that the gas penetrates if put it on one side and see the other get wer

Would lighter fluid (naphta) work too? Should be cheaper I think (not going to pay the government any more taxes than I need to )
