It’s about time for a slideshow!

A charango is a 10-stringed instrument that originated in the Andes and is traditionally made from the dried shell of an armadillo (hair and ears intact). Fortunately, they’re not made that way anymore!

I recently had the privilege of working on two charangos for local charanguisto Leo Lara, and these really were made the traditional way, so worth putting a lot of work into.

One of them needed only a little work, but the other one needed quite a bit. You can see some of the gory details in this slideshow.

It came to the shop because the action was too high to be playable and the peghead was broken. The peghead was a straight-forward glue job, so no problem. But since an armadillo neck can’t be reset to correct the action like on a guitar, we had to come up with another way. The fingerboard was much thicker on one end so we decided to remove it and make a wedge to fit under it in order to change the neck angle.

The first step was to measure everything and figure out how much the neck angle needed to change. Then remove the frets. Then remove the fingerboard using a heating element (that black thing on top of the heating element is just weight to keep it from moving around). Next make the wedge to the correct dimensions and glue it to the fingerboard. Then glue that to the neck, clean up all the glue and shape everything. Touch up the finish as necessary. Put frets back in, level and crown them (I used the same frets because they were in good shape and a different alloy than what we have). Then string and tune (at least an hour) and set it up.

It turned out great, and was a lot of fun to work on!

Thanks Leo and Kathy for trusting me with your instruments!

Slideshow time!

Ron Repairs a Top Crack

It’s a gripping story!  Watch here.

This kind of crack is very common and almost always caused by lack of humidity. The very first thing to do is humidify the guitar until the crack swells shut. This could take a week or two. Then it’s ready to repair. Small cleats of Spruce are glued on the underside of the crack in between the braces. There is a lightbulb and a mirror in the body so Ron can see what he’s doing in there. His Popeye arm barely fits inside!

Not another slideshow!!

Watch Ron repair a gong bass drum rim from the early 1900’s.

It’s coming apart at the joint where one end overlaps the other. It would have been made using hot hide glue, so that’s what it’s being repaired with. Hide glue works best when it’s hot because that’s when it’s stickiest. So Ron must have everything ready and move quickly!
