Re: Cosmetic repair to dark line?

Very small glass spheres and particles. They are readily available, more commonly called glass microspheres. Used a lot in fiberglass work as a light weight, strong filler. Hard to sand especially if the resin or HHG gets fully cured so don’t overfill and scrape/sand while still green. As far as I k...

Re: Cosmetic repair to dark line?

The hide glue and glass bubbles idea is from the aforementioned Iris Carr. She says the glass bubbles helps maintain the appearance of chatoyance in the wood and from this repair, she’s definitely on to something.

Re: Cosmetic repair to dark line?

To close the loop on this, was able to make an acceptable repair. Used hot hide glue mixed with glass micro balloons, tinted with Colortone aniline dyes. Vee’d out the “crack” (or whatever it is) to get rid of as much of the the black edge as possible and filled withe the HHG filler. Left it just a ...

Re: Cosmetic repair to dark line?

Thanks for the ideas, I’ll try both. Have you seen Iris Carr’s violin repair work on Instagram? She does a feathered repair but from the inside so she can match the grain and get a pretty good idea of how it will look before gluing.

Cosmetic repair to dark line?

Anyone have an idea how to deal with a dark, straight line in maple veneer. 614471DC-D892-4F69-9EFC-5A420C19E3CB.jpeg Not sure what happened here, but it is deep enough it won’t sand out, on the verge of going through the veneer as is. In the past, I’ve touched up with opaque tinted lacquer, but thi...

Shipping Guitar from US to UK

I’m working on a commission for a customer in the UK and will be shipping to him when completed. I’ve never shipped outside of North America and am exploring the details of shipping to the UK. I’m vaguely familiar with CITES, Customs and VAT. Nothing too exotic other than ebony and MOP. The rest of ...

Re: Venner supplies

I get black and natural veneer strips to my spec from Gurian Instruments in Seattle. One quarter the price of anyone else, but they have a $200 minimum. They have lots of other wood choices and combinations.

Re: Burst and French Polish?

I tint with sprayed shellac, sometimes very dark or subtle edge bursts. I first seal well with clear shellac, then spray shellac tinted with aniline dyes. Sand very lightly with 2000g, then seal with sprayed clear. Once sealed, I finish in the conventional FP manner. Just be careful not to overwork ...

Re: Tips, Tricks, Suggestion, Experience making laminated plates?

I laminate all my backs and sides, it's the preferred thing for the Selmer style guitars I make. I laminate both 15' radius spherical backs and vaulted backs ala an archtop. The degree of recurve in edges is what mostly drives the amount of darting that needs to be done. I use three or five layers d...

Re: Using a clothes steam iron for bending sides?

You want cheap, how's this? My side bending rig is a propane torch stuck inside an uncapped pipe, held in a steel vice. Works great. The trick to easy bending is having the pipe plenty hot and the propane torch gets it more than hot enough and right now. Just don't get too close to the open end of t...

Re: Building guitars without a dedicated workshop? Outside? Inside?

If you just want to build one guitar, you can do it most anywhere. 45 years ago, I built my first guitar on a screen porch without electricity. My only power tool was an electric drill which I took inside to use. When I started building in earnest ten years ago, my initial set up for the first 30 gu...

The dust from Rocklight Ebano is like wood dust. I've had no problem with customer acceptance and have sold all the guitars I've made using Ebano fingerboards.

Richlite is not the same as Rocklite. http://www.rocklite.co.uk/ I buy Ebano fingerboards for ~$32 each. I know next to nothing about Richlite except on their website, they say it is a resin infused paper product. Rocklite is definitely a wood product, albeit sliced up and resin infused. Ebano feels...

Re: Synthetic Fret Boards

I've been using Rocklite Ebano on my new guitars and fingerboard replacements for about two years, roughly 20 fingerboards worth. I had been using rosewood and liked it, but developed a skin sensitivity to rosewood and had to stop using it. I've come to not like ebony much as it seems unstable enoug...

Re: Endurovar repair

I ordered a pint of General's High Performance. They say it is water clear. It is also softer, to the point that some people say in reviews that it is not suitable for a guitar finish. For polyurethane repairs at the boatyard, however, we use a softer polyurethane which makes for easier polishing ou...

Or maybe drop fill with General Finishes High Performance Gloss and polish out? General's website says HP is water clear.

Re: Adapting guitar playing for ex-special forces guy who lost finger

I don't have any direct advise though the slide idea sound promising. My thought was to have him read the Django Reinhardt story. Django lost the use of his 3rd and 4th finger on his left hand from a severe burn early in his career. Everyone thought his career was over but he adapted his playing to ...
