Ibanez Concord 751

I have an Ibanez Concord 751 on my work bench which is in need of a bridge removal, sound board flattening and bridge re-glue. On inspection I found the bridge has a bolt through it and through the soundboard and bridge plate through the centre perloid dot inlay. Does anyone know if the dots on the ...

Truss rod nut 1974 Ibanez

I have a 1974 Ibanez Country Classic copy in for repair which needs a new truss rod nut.

The Allen head has been stripped by using the wrong size key.

Does any one know if this is an Imperial or metric nut?

And where I can obtain a new one?

Re: Neck geometry question for semi?

Thank you Freeman. 1/8” of arch is surprisingly little. On a couple of plans I found online, 1/2” seems more common. In any case, I have my answer. All the dimensions that make up the neck geometry are tweaked and not standard to Gibson arch top guitars despite some visual similarity. I’ve spent so...

Re: Cutting fret slots failed. And now?

What I have done when inadvertently cut a slot in the wrong place is filled it with veneer of the same species and as close a colour as you can find cut of the end grain of a strip. Gluing the veneer in with cyano and making sure it is proud of the fretboard face then sanding it down level and pushi...

Re: Repairing worn wood around soundhole

When a customer asks me for a cosmetic repair This is not really a cosmetic repair. Nick, the owner plays, amongst other styles, a very percussive style we call "Boland Bop" and it is wearing the sound board out around the hole quite aggressively. The edge is about to wear through and then the hole...

Re: Repairing worn wood around soundhole

Thanks all.

The consensus is: Clean, seal with shellac and fill with CA and cover with an auxilary pickguard.

Now to get he guitar into my work shop. It is a hardworking pro's instrument which has very little downtime.

Repairing worn wood around soundhole

Any thoughts or recommendations on repairing this damage around a sound hole on a Taylor guitar? The owners playing style has worn the wood out from between the inlay. My idea is to route out the damage and replace the wood tinting it to match then cover the area with an auxiliary clear pick guard. ...

Re: Making keystone style rosette pieces

2. Cut inner circle of the rosette's border strip into your top, and without changing the circle cutter's settings, also cut this circle into your glued up circle of tiles. Make your border strips to be the same thickness as this bits radius.
Shouldn't that be the bits diameter?

Re: using acetone as a glue for binding

I have found using Clear PVC Weld for the wood/plastic interface works very well. Then acetone to bond the subsequent layers.

Re: Chapman stick?

Here are some shots of the CAD drawing I did to get the layout defined.

I'm not sure if this thread belongs in the Acoustic forum? Perhaps one of the mods could move it somewhere appropriate?
