Re: Ideas? Dinged Spruce Soundboard (photos)

If steaming fails, try, try again. I used to repair and touch-up furniture and some pieces that had corners crushed in an inch or more when steamed for more than an hour regained most of their original shape. I would then wick in thin superglue to give the wood some integrity. As Peter said, it look...

Re: Tuner holes on purchased neck larger than tuner collar

I bought some of those premade necks for some cigar box ukes I made. I wanted to keep the peghead weight down, so I plugged the holes, added a thin face veneer, and redrilled them so I could leave off the bushings. It does seem like they drilled overly large holes for most tuner applications.

Re: Ugh! Big Bad Router Screw-Up. Suggestions Please.

Not pressing the bearing against the side hard enough to keep it from spinning with the bit can be a problem. Assuming your bearing is greased properly and the bit spins freely then you should put enough pressure against the side so the bearing "rolls" while the cutter "spins".

Re: New Selmer/Maccaferri style guitar

I would encourage you to continue with your laminating experiments. It can allow you to use some exceptionally beautiful veneers in a cost effective manner. Laminating rosewood veneer to softwoods is not a new idea. It was practiced in the mid 1800's until the price of imported wood dropped enough t...

Re: Where to get vintage wood tuner pegs?

You might be able to fit a set of rosewood or boxwood violin pegs to the uke. If you know any wood turners you might be able to have a set turned.

Re: Fretting Templates

If you can get them to add a couple of frets to the bottom of the template you can use some (23 fret) bass scales to double as guitar templates. A 34 inch bass scale can also be used as a 25.5" guitar scale with the addition of two frets at the bottom (to make 20 frets). It will also work for a 27 i...

Sanding pad reconstruction

You have to love urethane foams - the kind that self destruct over time. I've had that happen on a Makita planer I own and the sanding pads for my PC sanders. I ordered some new pads for my sanders, but decided to see if I could "rebuild" the old ones. I didn't want to do the "six million dollar man...

Re: Martin N-20 Folk Guitar repair

Hi Paul, The magnets on the strip are all oriented the same way and are repelling each other. The magnets on the second strip are oriented to be attracted to the first strip (but again repelling the other magnets on their strip). I used clamps to hold the magnets in place while the glue dried. I can...

Re: Martin N-20 Folk Guitar repair

Hi Barry, The magnets did provide a good amount of clamping pressure for clamping the veneer cleat. I'm sure it would vary depending on how far apart the magnets were kept by the thickness of the sides. As a first iteration I am happy with it and I think it will work for most situations. I do see ro...

Re: Martin N-20 Folk Guitar repair

flex mag caul 1.jpg Hi Barry, I played around with the flexible caul idea we talked about. I used some round neodymium magnets I had on hand. I placed them in square corian holders and glued those to a strip of cloth. The first set I left square, but then the light bulb came on (briefly) and I thou...

Re: Martin N-20 Folk Guitar repair

Hi Barry, My thinking is that since the cleats span the entire length of the crack (unlike diamond cleats) the veneer may be strong enough. I do have some veneer that is probably thicker than .056" in mahogany (?) and some lighter and darker woods, so I could try making some thicker cleats. On the w...

Re: Martin N-20 Folk Guitar repair

If you buy some neodymium magnet discs or squares from Amazon or the local big box store you could mount them to a cloth strip and leave a small space so they could flex between the magnets and conform to the side of the guitar. As I mentioned I was inspired by Thompson's system to use veneer strips...

Re: Martin N-20 Folk Guitar repair

When I first saw the system it looked like it would work pretty well. You have shown several of the things to be taken into consideration when using it. It builds on the the idea many of us have used for crack repair. Previously we used magnets only to align and level cracks. Now they are being used...

Re: Martin N-20 Folk Guitar repair

neodymium magnets.jpg I didn't think about mapping out the brace locations. Thank you for showing that. You mentioned you need to trim the caul - are the cauls integral with the magnets, or can you buy additional cauls and attach the magnets to them? I was looking into buying some magnets to do som...

Re: Martin N-20 Folk Guitar repair

P.S. Some people like to convert the G series classicals to steel strings - the attraction is the nice rosewood that was used and the G series body is shaped more like the steel string guitar. The N series has the typical classical shape - it would make a Gibsonesque LG type steel string. Martin cla...

Re: Martin N-20 Folk Guitar repair

Hey Barry, I found the T.J.Thompson continuous cleats inspiring. Since they span the entire length of the cleat I'm thinking they don't need to be too thick. I decided to experiment with using veneers. I cut the veneer strips with scissors. Since the grain runs perpendicular to the crack, cutting wi...

Re: Gibson LG-0 bridge

Is it possible that they cut down the original bridge and then capped it with a rosewood one (epoxying the two together)? If it is well glued down and structurally sound I would just repair the crack between the pin holes and call it a day. Curiosity killed the cat and made a lot more work for the r...
