Re: Bondic UV light curing glue

I use Bondic and other UV light-cured glued in technology repairs. It's great for surface coverage and protection applications and cable abrasion repair. successive layers can be applied after curing to build body and I haven't witnessed delamination in that scenario. Incomplete curing causes issues...

Re: Sapele bending help

I have experienced spring back with Sapele and found that my pipe temperature was too low. Something to do with the lignin in there, I suppose. I have to bend Sapele with a much hotter pipe than anything else to avoid the spring back. This, of course, increases the odds of burn marks if you're not m...

Re: Color Theory

Instead of mixing up a color batch for aging the look of new wood, have you tried Potassium Permanganate in water? It's an oxidizer that I use often to achieve the darkening caused by time and exposure to air. Kind of like speeding up time. You can dilute to suit the amount of oxidizing you need.

Re: Ukulele Intonation Mystery

Hurray for the MIMF!

A quick update. It was indeed the string itself which was the cause of my intonation woes.
I was so focused on the scale math that I seriously doubt I would have considered that the problem could be with the string!

Thanks again everyone!

Ukulele Intonation Mystery

I have a problem with a current ukulele build that has me stumped. I built a concert size ukulele with a 14.75" scale length. Pretty straight forward build. The problem I have run into concerns the intonation of the third string (C). Strings 1,2 and 4 intonate perfectly but the 3rd string is another...

Re: Walnut for fretboards?

I have used walnut for fretboards on numerous instruments over the years. While it is true that walnut is softer than many of the standard options, I have fund that the durability is often determined by the player. One customer has a walnut fretboard on an SG concept copy which was built 10 years ag...

Re: Spare holes in fretboard-how to cover

Bob, I have felt your pain. Think of this as an opportunity. Bob Gramann's suggestion is the direction I would take first. If you have any scrap from the fretboard available to test on see how well it takes to a closely matching inlay. The grain of the wood should be matchable as it appears quite st...

Re: Rethinking Alaskan Yellow Cedar

I've used it for numerous guitars and have been very happy with the tonal quality. The wood I have was cut in 1890 and is from old vinegar tanks so the smell and taste is closer to pickles than skunk.

Re: fretboard/bridge woods

Here's that picture of the walnut fretboard. Curly maple Inlays give it plenty of contrast. Gave it a Tru Oil wash before radiusing, then a liberal application of orange oil after all inlay and finish sanding was completed. This shot is a just after the orange oil was applied. After a week the color...

Re: fretboard/bridge woods

I've used walnut in quite a few fretboards and have not experienced the softness mentioned by others. On fretboard is now 10+ years old and gets regular use by an aggressive player and it is fairing better than some rosewood fingerboards I've seen. I'll post a picture later this evening.

Re: Mistakes made while building early guitars

My biggest lesson learned was understanding humidity and its effect on the build process. I live in Minnesota and early on I built a few guitars in the summer and the following winter when the humidity dropped my guitars cracked in a BIG way - tops and backs. In frustration I made a call to a local ...
