Re: New Luthier Tips du Jour video - Laminating sides

I have tried all sorts of laminating methods and glues. The water based glues, eg Hot Hide Glue, do not set in a vacuum. So that means that laminated sides need to be male and female molds, or using an air inflated fire hose to press the laminations into a single mold. I like the idea of HHG over ep...

Re: Rosewood article

I've started the process. Been growing these Acacia Melanoxylon (Tas Blackwood) in my workshop since January. I'll update this thread in about 30yrs when she's big enough for a headstock veneer. If you are growing it in your workshop it won't get big enough for B&S sets unless your workshop is as b...

This one too if you need one? One use that comes to mind would be for a back slanted saddle pocket. In fact on further inspection of the link that is exactly what they demonstrate on the "learn" tab on the page. http://www.stewmac.com/SiteSearch/?sear ... ter%20base

Re: Cutting 1mm slots / rings for rosettes

As regards to the use of superglue on raw spruce, I have found occasionally that the superglue stains the wood a greenish tint. Does anybody else experience this and what would the reason be for it only happening on some spruce samples and not others?

Measure the scale length on the first string then calculate, look up an online calculator or use a phone app like the one I use (an iphone one called "fret calc"). You can then measure the fret spacings and the first fret to the nut distance on that string. All of the previous tips re nut and bridge...
