Questions: Digital Photography

Questions: Digital Photography

by Byron Will, and R.M. Mottola

James from Cincinnati, Ohio asks:

I’m switching from film to digital photography. I’d like to take photos to send to clients during construction and post on my website. I’d also like to take really good studio shots for my portfolio. I know this can’t be answered comprehensively in the Questions column. Right now I’m looking for tips and/or directions to pursue.


Byron Will of Portland, Oregon answers:

My experience taking photos of my harpsichords and other instruments and teaching digital photography at the community college here might be of use. You don’t mention if you’ve already purchased your digital camera. If not, I recommend you check out these websites that I’ve found very helpful for determining what to buy: www.dpreview.com and www.steves-digicams.com. Bear in mind that the quality of the optics is as important as the number of megapixels.

Mirror with Penlight

Mirror with Penlight

by Tim Olsen

Originally published in Guild of American Luthiers Data Sheet #22, 1976 and Lutherie Tools, 1990

 

Simply tape a penlight flashlight (Eveready Heavy duty will do), to a dentist-style 1" round mirror with a 6" or so handle. 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. ◆

Questions: Lutherie Related Skin Rash

Questions: Lutherie Related Skin Rash

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.

Questions: Spalted Maple Mold

Questions: Spalted Maple Mold

by Bob Woodcock

Originally published in American Lutherie #69, 2002 and Big Red Book of American Lutherie Volume Six, 2013



Mike Collins of Argyle, New York asks:

I just came across some nice spalted maple and made a rosette of it. 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.”

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.
