Default X-braxe slightly moved aside...

This morning I noticed that the x-brace of my 12-string baritone had slowly glided a bit (c. 0.5 inch) aside
due to the pressing bars of the go-bar system.
Should I let it as is or should I better remove the x-braces and glue again properly?
It seems to me that this mistake has given the soundboard a tad more room for the bass tones...

Well, I decided to leave it as is.

It seems you have accepted your fate and there are no other takers so I will jump into the fire. You say .5" but it looks like the same or less then the width of your bracing. Maybe .318" or so. Next how about the bridge ends, they have to be on both legs of the X. But more important to me is the standard you set for your workmanship. If you set high standards you most likely will have to push yourself and always try to improve your game. This is how one hones skills. Always try to do the best you can BUT never be satisfied.

P.S. Read Bruce Sexauer's threads, they are heavy will this same philosophy.

The only thing I will suggest you check is that the brace has proper glue coverage along (under) the side of the brace in the direction of the slippage. As it slipped, it could have left most of the glue on the trailing edge of the slip, leaving a glue-starved joint for a sliver along the leading edge of slippage.

You can easily take a thin bladed palette knife or similar to see if it can penetrate the seam. If it can, you'll want to carefully wick glue into the seam to ensure a joint with proper glue coverage.

Other than that, no big deal at all (for a hobby builder, that is). For a pro, he/she should remove the brace and re-glue.

Tom, you are right.
I was up to re-glue the x-brace. Then I phoned a professional and he said I could live with it and the guitar,too.
This one is for me and I will never sell it. If I were prof I´d get the thing off again,tho.

Ned, thanks for your very important hint about the glue. I will have a careful look at it and lift off all what´s not tight.

I've been building one for about...well...a long time. It's taken me longer because every time I make a mistake, I take it back apart and do it right. Some mistakes were irreversable (measure twice, as they say!) but glue joints can be pulled apart, cleaned up and redone. I think you might have tried to glue too many braces at once. When I did mine, I did the bridge plate first, then the x brace, then the other braces.

I'd fix it if it were me.

Is that upper finger brace on the treble side the same wood as the other braces (which I assume to be spruce) ?

It's presumably a trick of the camera/lighting, but it looks like it is made of plywood ...

I thought of changing it for one of the whiter spruce bars. But it has the same weight and (darker) vertical grain like the others.
I dunno how it managed to sneak into the lot

>>> I shaved it off and added a white new one. Nothing offending my eyes anymore

Just get your Marketing Department to patent the new 'Slipped Brace' system and boom good to go.

No, I´ll leave it as an "open source" free to use for anyone.
Btw, it moved only from down left to up right 0.19"...
The other brace was just pushed a tad on its line to the upper left side.

I position my bridge plate first and all the other braces off that. It would be hard for the x-braces to move when butted to the plate.
