For my previous guitars I have either purchased pre made purflings or assembled single pins at the time of binding and installed the pins and bindings at the same time using CA. For this guitar I want to sandwich some osage orange between some .010 black pins. I have the black veneer but am wondering how best to go about this. I think the .010 is just too fragile to assemble at the time of binding. My thought was to rip a slice of osage about an inch or so wide, run it through my thickness sander to get the desired width, then build a sandwich using the veneer. Once glued up, I could rip the sandwich using my uber thin kerf fret blade on my table saw.

I am concerned about getting those joints really tight on glue up so my purflings don't look wavey when done and installed. I could use a couple of heavy boards as cauls and perhaps use my iron when done to really get any bubbles out. To you guys that pre assemble your own, and tips you would recommend? I don't want to glue the purfs to the bindings. I just want to make the purfs.

Thanks,

Ken

La em out and glue em together. Don't do too many layers at once.

Hi Ken,

I went through my setup in the thread I am doing in the tutorial section. It is here:

viewtopic.php?f=10117&t=29270&start=0

If you make it to page three there is a post from Laurent with a much improved method for slicing the glue-ups. I have the press that I use but clamping between boards also works perfectly well, I did that before I made the press.

Hope it helps

"pins" is a new one on me. It means?

When all else fails, clean the shop.

Burton, great tut!
I was asking myself why I never saw this,
becase I didn't even know that forum section existed!
Laurent, thanks for the block-for-cutting-bindings.
Nice and safe.

Pinstripes.

Thanks for the replies, guys. I was busy in the shop and didn't have a chance to get back to this until today. Burton, nice link. I appreciate you posting it. Unfortunately, I didn't see it until I was all done!

In general, the process went pretty well. For the wider purfs, I used black veneer and the only issues I ran into with those were the the veneers not gluing down well in a couple of spots. I'm guessing I didn't apply enough glue. I closed the gaps and wicked in thin CA. Hopefully once I rip into strips, the lams stay together.

For the thinner purfs, I used black fiber. I applied more glue and made a raked glued spreader out of an old plastic card. Once the glue was on, I ran this spreader down the wood to put the glue into little furrows, hopefully providing more even coverage when clamped up. When I removed these pieces from my clamps a couple of hours later, the black fiber had ripples along a couple of the edges. I ripped the lam into pieces and had plenty of good purflings despite not being able to use the full length of a few of the outer ones.

Like you Burton, I really liked being able to build exactly what I wanted. I don't feel too comfortable in my process yet, though. I need to figure out how to get enough glue to fully glue the laminations, but not result in ripples or washboards.

Last night I used the new purfling for the rosette for my spalted mango FB-185.

Howard, I used the term pins when working with string inlays in furniture. Maybe it isn't that common in the luthier world.
