Position the light to get a 1" spot of light and so that the beam is entirely reflected into the instrument to be inspected. Sight down the barrel of the penlight. The area you see in the mirror will always be full illuminated. This was Dale Kormo’s idea. ◆
Posted on January 19, 2010September 10, 2025 by Dale Phillips Questions: Lutherie Related Skin Rash Questions: Lutherie Related Skin Rash by Udi Vachterman Originally published in American Lutherie #80, 2004 and Big Red Book of American Lutherie Volume Seven, 2015 Udi Vachterman from Rehovot, Israel writes: Way back in American Lutherie #58 there was a question from Henry Kingery of Pittsfield, IL. He wrote about a severe itchy skin rash presumably brought on by woods or chemicals in glues. He was taking a synthetic steroid to keep it in check. I know it has been a long time, but I would still like to tell him and others of my experience with a similar problem. A few years ago, just a few days after being exposed to a lot of chemicals and wood dust (an Argentinian wood called “algarrobbo,” which I believe to be “carob tree”), I noticed that small extremely itchy liquid-filled bumps started appearing on the backs of my hands, especially around the joints. With time the bumps developed into shallow wounds and spread toward my wrists. Similar symptoms appeared on my elbows and the upper part of my feet. I went to see four doctors who each had a different diagnosis of my problem. However, they all advised the same treatment, cortisone creams. Yet, they all told me that the cortisone is unlikely to cure the disease, just help manage its symptoms. However this did not make much sense to me. If I am sick, then I want to know what it is and not have four opinions of what it might be. So I went to seek advice of the local pharmacist. To my surprise, she told me that her son has, or had, to be correct, the same problem. It’s a type of psoriasis, a skin disease that is often the body’s response to a trauma caused to the skin (skin injury, skin infections, reaction to certain chemicals). Her treatment was as follows: 1. Extensive use of natural hypo-allergic moisturizing cream. 2. Fish oil (omega 3 essential fatty acids); 3 capsules daily, 1000 MG each, taken with food. 3. Tea tree essential oil used topically for itchiness. After a few months all my symptoms disappeared. My hands were almost like new and I have since built a guitar, inlaid it, and finished it without any of the above mentioned symptoms. And I can once again play my guitars without bleeding while bending strings! If anyone tries this and it helps them, I’d love to hear from them: vachterm@hotmail.com.

After I was done, a violin maker told me that you could die from the mold in the wood. Where can I get more information about this? A few days later, Mike wrote back with this information: I found a website, www.woodbox.com/data/wood/ that has some information on spalted wood and possible health problems. Here’s an excerpt: “Spalted wood may still contain spores, therefore it should always be worked and sanded only when wearing a good dust mask or respirator, and using a dust collector. There is medical evidence that substances from decaying wood are a health threat, and some allergic reactions and serious lung diseases have been traced to spores and fungi that inhabit rotting wood. The effect on an individual woodworker however depends on his/her natural tolerance to the spores and fungi, since some individuals are more likely to react to environmental toxins than others.” Become A Member to Continue Reading This Article This article is part of the Articles Online featured on our website for Guild members.

Posted on January 19, 2010September 10, 2025 by Dale Phillips Product Reviews: Slotted-Head Tuners Product Reviews: Slotted-Head Tuners by Todd Rose Originally published in American Lutherie #79, 2004 and Big Red Book of American Lutherie Volume Seven, 2015 Slotted-Head Tuners This is for those of you who share my passion for the other kind of steel string guitar head, the slotted head. Whether it be a case of carrying on the classic designs of past instruments (as with parlor guitars, resonator guitars, and Selmer/Maccaferri-style guitars, to name a few) or breaking new ground with contemporary designs, a slotted head on a steel string guitar is a compelling stylistic element. To my eye, a slotted head has striking lines and elegant features: The plane of its face is unbroken by protruding tuning posts; the slots lend a lightness and transparency to its bearing. Recent years have seen a resurgence of interest in parlor guitars, including some beautiful contemporary interpretations of this traditional form, as well as other styles of guitars with slotted heads. We may well see a growing lust for this style of head on the guitars of the future. While designing my own nontraditional guitars with slotted heads, I found, as have many guitar makers, that the selection of tuning machines appeared woefully limited compared to the many styles available in the solid-head type. Determined to exhaust the possibilities, however, I ferreted out a few models of which I suspect many are unaware, and also found that there are sometimes more knob and finish options in the manufacturers’ own catalogs than what’s regularly available from suppliers. Furthermore, at least one manufacturer has a new line of slot-head tuners in the works, and others may be able to offer more choices if guitar makers ask for them — more on that later.

Posted on January 19, 2010September 10, 2025 by Dale Phillips Questions: Upright Bass Questions: Upright Bass by James Condino and Randy DeBey Originally published in American Lutherie #80, 2004 and Big Red Book of American Lutherie Volume Seven, 2013 Dan Poehnelt of Marshfield, WI asks: I have a client who would like me to make him an upright bass. Do you have any idea where I can get some specs or instructions to make one of these? Rhett Runolfson of Springville, UT asks: I mostly work with guitars but the local music store said that if I helped them with setups on their orchestral instruments, which are shipped in from the Orient, I could probably get some of their guitar work too. Well... I’m getting my butt kicked on this bass. I have to remove the fingerboard and shave the neck down to get the proper angle. How do I get the fingerboard off? Heat and a seam knife don’t seem to be doing the job. And what is the proper angle for the neck for a contra bass? Is there a book that I could pick up on orchestral instruments that could tell me these things or would someone know a secret on this Oriental glue that is impervious to heat?
