I have a couple resonators I would like to re-skin. One a maple finish Masterclone that has some Asian inspired MOP inlays that I do not enjoy, the other a Vegavox I that appears to have an artificial wood finish (paper?) that I would like to dress up. I assume the process will be similar for both.

Can anyone outline the basic steps to this process,  Should I remove the original veneer? clamping method? What glue for new wood veneer? How do I avoid the new veneer wrinkling as it is clamped into a compound curve?

New veneers are so thin they will lay over the resonator without puckering.

How thin veneer should I be looking for?  I have some ebony close to 1/16" I bought years ago for peghead overlay I was thinking of using on the Vegavox.

I believe the ones that just lay on are thinner than 1/16"
When I had Frank Neat finish a Cox resonator in '08 Jimmy Cox told me that about the new very thin veneers.

Thanks Bart, I typically use A&M in Cambridge. That is where I bought the ebony back about 1980.

I use a two step process of vacuum veneering and regular pressing. Got all the info and equipment needed at http://www.joewoodworker.com/veneering/welcome.htm really great site. Nice veneer glues which are worth it because they don't leak through the thin veneers. So I vacuum veneer the back and then do the sides with multiple wraps of inner tube strips. Last I cut the binding ledges after applying a thin shellac layer to strengthen the veneer edges and prevent blow-outs. It is possible that you could veneer the back with lots of inner tube but the vacuum process is pretty easy. I have done this with several Saga mahogany resonators to upgrade them with walnut or maple.  Good luck!

I was wondering if laying something soft and heavy like a bag of sand or rice over the back might work to clamp it?

I would first soak the veneer in water till pliable. and lay it back down on a couple layers of close-celled foam pads that they sell for backpacking. Stack the inside with sandbags, barbell discs or some other heavy material. Use enough weight to press the veneer sandwich into the foam padding. Let it dry overnight, and the next day it should have taken the correct curve. Apply glue and stack it up again till the glue sets. 

If you preferred to eliminate the weights, you could cut a disc out of 3/4" plywood and add it to the bottom of the sandwich. Then you could clamp it all the way around with C clamps.

I think this would work for the typical 1/32" or less veneer thickness. I doubt if it would work with veneer as thick as 1/16".

Jimmy Cox invented his own veneer remover.A kind of "nibbler" that was adjustable to the depth of the veneer.

A manual one could be as simple as a sharp,depth adjustable pin mounted through a plate.
Drag across the grain every 1/2" and pick out the pieces.

A ball or mounted on your milling machine or drill press table similar to how they rough carve mandolin tops. Lower a router bit to the desired thickness and move the resonator around on top of ball.
