While routing the channel for my binding on my sound board (sitka spruce) I had a fairly large tear out. How is the best way to repair. I did save the sawdust that came from routing. Any help would be appreciated.

Thanks in advance!

Baking soda box Why did I change the color of this baking soda?

Maybe you already use the “Baking Soda and Super Glue Trick” as a fast patch, but here’s a new twist.

What exactly happened? Did you clip a piece off the wing of one of the bouts or did you make a little circular punch past the intended line of the rebate? Can you give us a picture to help us understand the size of the tearout?

If it's a REALLY large tear out, I'd probably splice a piece of spruce.
But if it's minor, like I'm guessing it is, a good solution is thin superglue,
Once the guitar is ready for finishing, and a sealer has been applied, fill the tear out with thin superglue until it's level. Then complete the finishing.

Thanks guys,

I posted this on another forum and determined that the purfling channel will cover most of this and the rest I'll try to cover with the CA, baking soda, sawdust trick. We'll see what happens.

Larry, if you haven't routed the purfling rebate yet, now is the time to see if you can splice a piece of off-cut spruce cleanly. As appearances go, it will look much better, with real grain and everything. I always reserve the offcuts until everything is glued up just in case I have to do this and it's paid off a couple of times. Once it's spliced and you've cut the purfling rebate, it will look great. There are down sides to the CA/baking soda/ sawdust method. First, it's a dead giveaway because there are no grain lines and the color is going to be different no matter now hard you try. Second, the patch is going to be harder than the spruce and just won't sand down easily to the same level as the spruce. It's too easy to leave a very slight bump.

If you're on the horns of the dilemma, there's no harm and little time lost just trying out the CA on a scrap to see if you can live with the look.

Best of luck,
Bob
I routed the channel for the purfling already and it took away the problem, I had forgotten I hadn't done that yet when I posted. I'm in good shape now. Thanks for everyone's help.

Larry
Cool. Live it up. No bullet quite like a dodged bullet.

research climb cutting this is what need to take place with the router in order to not tear out
