Hi, laminating archtop guitar tops and backs. My method involves using 4 sheets of 3/32 inch baltic birch plywood sandwiched between veneer face veneers. The problem I am having is that the joint line on the face is slightly thick. It is just bad enough to make me look twice and try to convince myself that it is okay, but of course it is not. I used very curly maple veneer and needed to sand it to keep it from chipping. I then tape the veneer on the glue side with painter tape to bring the two halves up tight, flip it over and use 3 hole veneer tape to the show face. Then I remove the painters tape. I place the veneer glue-up into the bag on a convex form so that the show face of the guitar plate is down. I think the concavity is causing the veneer to contact at the bottom and come apart slightly on top showing a gap.

What can I do. this is very close to good but not quite right. I was thinking of perhaps angling the veneer joint so the joint looks like //. Is there another way. I know it can be done, since I have seen many Gibson and Gretch guitars with a perfect joint.

thanks.

Kenny,

I have two suggestions.

First, dont use three hole veneer tape, its not particularly strong. I would use no hole veneer tape, it has much better holding power.

My other suggestion is to glue the veneer edges together prior to pressing. This is the solution I recommend in your situation. After you apply the masking tape, fold the veneer back on itself at the taped seam and apply a bead of yellow glue. Lay the veneer back flat and wipe off the squeeze out on the glue side. To assure the veneer is level at the joints put it in your vacuum press for a few minutes, this will be enough time.

I use this method whenever I have trouble holding the veneer joint together.

Sincerely
Darryl Keil

Kenny,

I'm so glad my suggestions helped.

I feel like those guys on the NPR radio program "Car Talk" where they go back, revisit someone that they gave advice to and find out how things went afterwards.

Sincerely
Darryl Keil
