Ben how do you keep the veneer attached to that carrier stick that you are using to put them through the sander? Very interesting process.

I am loving the color choices for the rosette, the blue is really a nice touch!

The carrier has 120 grit PSA sandpaper on both sides. I take really light passes once I get past about .020". This set of purflngs has .010" maple in it, and the fact is, I lost a couple in the innards of the machine- If they get caught up or folded, they are DUST! But I always plan on losing one or two if I'm doing a batch. Someday, I'll get a wide belt sander......sigh.......

Test laminated side
In my former life (one of them) I was a cabinet maker, and that put me in good stead for my current (and final) life as a luthier. As a cabinet guy, I made lots of jigs and became versed in veneering and pattern making. This is very handy nowadays.
My customer has asked me to make this guitar with laminated sides. There is a lot to recommend laminated sides- they are very stiff, can be built perfectly flat across their width, are crack resistant, and add some weight and heft to the guitar that can act as a springboard for the top and back. There are a lot of opinions about this, but I am game, and it certainly won't hurt anything, so here I go. I like to learn as many techniques as I can. First, I built a laminating plinth. This guy has to be perfect, because any lumps or bumps are going to be transferred into the sides. It's made out of 8 layers of plywood, and because I am a fastidious weirdo, it has three coats of enamel to make it pretty. Plinth.jpg I thought I would do a test run with some inexpensive wood before I subject the beautiful BRW to the unknown. I used some peruvian walnut and maple for this test. Like so: Plinth:veneer.jpg I'm using a veneering (vacuum) bag to smoosh the veneers together on the plinth. Here's everything all laid out and ready. I'll epoxy the layers together with T-88, so it would take and Act Of God to separate them ever again. Ready bag.jpg Everything together, and into the bag it goes. The vacuum pump draws air out of the bag, and the mighty weight of the atmosphere presses the veneers together with (we hope) nary a bubble or wrinkle. vacuuming 1.jpg vacuuming 2.jpg So, there it is, in the bag. WILL IT WORK???????? Tune in tomorrow to find out! hint: i suspect it will. |

Hey, I just had a great idea, since you are basically making all new jigs for this ultimate Wilborn and then testing said jigs with test woods before going with the real stuff, can I have the guitar made over from all the left over parts? Sort of like that old Johnny Cash song building the Cadillac one piece at a time.
I think this sounds like a ingenious idea!!!!!!

Double sides...
John Kinnaird has built all three of my customs with double sides. Since he makes each of the pieces thinner than a normal side, they are not that heavy.
And they are pretty bulletproof... Maybe JK will chime in on the sides. It sounds like you are having fun with this. Cool to learn new stuff! CU in Texas Paul

I would love to hear from John K. on this one. I am likewise making the laminations thin, but it will still be more massive than my normal.080" sides. |

Onetime I saw him in this little sequined number...wow.
I'll take this as encouragement from the Master, Bruce. So: Thank you! |

Test side is good!
Well, it worked. This side is as flat and stiff as I could have hoped for, and it only displays the slightest amount of spring-back (deformation away from the mold shape) .
Now for the real deal.... IMG_0212.jpg IMG_0213.jpg IMG_0214.jpg |

Perfect, so glad to see my side came out so well. I was thinking you could bind the side of the top without a side and then do a post and beam construction type of thing to support the top. Would be kind of cool to look inside the guitar easily. Would make for one big sound port, probably no need to cut a sound hole in the top either.
