Skin Heading Ethnic Drums, Etc. by Topher Gayle Originally published in American Lutherie #2, 1985 Derbeckis (A.K.A. dumbegs or Arabic tabla) are medium-sized (10" to 18") hand drums used most frequently in Middle-Eastern folk and Belly-Dance music, and also heard in jazz idioms. Two main types of the drum exist: metal bodied drums, usually Turkish, utilizing a mechanical drumhead tensioner much like that on bongos or conga (which drummers frequently want to have replaced by banjo tensioners); and the clay-bodied drums which come in a large variety of sizes and shapes. Wood-bodied drums also exist and may usually be treated as clay (for the most part). Tim Olsen asked if various skin-headed stringed instruments might be treated by this device. I have not done so myself, but I don’t see any serious complications. A radiator hose clamp chain can be used to fix the skin to the side of the body if the body side joins the top at a right angle. I used this technique on a small wooden drum with good results. Blocks were required to raise the body up to the top frame hex, since the drum was so short. The skin was brought up to tension as described below, and then the radiator clamps attached. The assembly was let dry just as is usually done.

Posted on December 27, 2020March 6, 2024 by Dale Phillips One Way to Make Kerfed Lining One Way to Make Kerfed Lining by Richard Ennis Originally published in American Lutherie #2, 1985 In general, linings exist in three or four types, all of which are related to one another. There is the solid type which must be bent before use; individual blocks, which might be thought of as the solid type of lining cut up to a more manageable size; laminated linings, another variation of the solid type; and kerfed linings. The kerfed lining is perhaps best seen as either a line of individual blocks linked together, or as a solid lining kerfed for flexibility. Here is how I make kerfed linings. It is a method with very little wastage and is efficient for use in a small workshop. When using the approximate dimensions given below it produces a lining that appears as a series of individual blocks linked together on a wooden ribbon. I select my timber for linings by giving first consideration to the working properties. I want to avoid ragged edges from the numerous saw cuts, but look for wood with good gluing capability, that sands well, and that is not too fractious and inclined to split. Willow, alder, and linden are all good candidates, as is tulip tree wood, sometimes marketed as “yellow poplar”.

Posted on July 6, 2020March 6, 2024 by Dale Phillips White, Yellow, and Hide Glues White, Yellow, and Hide Glues by Lawrence D. Brown Originally published as Guild of American Luthiers Data Sheet #174, 1981 and Big Red Book of American Lutherie Volume One, 2000 This article originally appeared in the FoMRHI Quarterly No. 18, and appears here (revised and expanded) with the kind permission of that organization. Ultimately, the quality of a musical instrument depends not only on the sweetness of its tone but also on its continued service and durability in a variety of climates. Deterioration of an instrument may occur from internal or external forces. External forces are those that come from hard use or from string tension. Internal forces are the result of the natural tendency of all woods to shrink, warp, and shift position in response to changes in moisture content. Poorly shaped parts that have been forced together by clamping pressure are also capable of generating internal forces by the steady pull on the joint caused by the misalignment. The structural integrity of the instrument, its ability to stay together and retain an attractive appearance over a number of years, depends on four things: the choice of carefully sawn woods with a uniform, low moisture content; the type and design of the joints used; the experience and expertise of the builder; and the adhesive used in construction. The concern here is glue, although some discussion of closely related factors such as joint design and humidity is unavoidable.

Posted on May 21, 2020March 6, 2024 by Dale Phillips A Laminated Neck Design A Laminated Neck Design by Tim Olsen previously published as Guild of American Luthiers Data Sheet #50, 1977 and in Lutherie Woods and Steel String Guitars, 1997 The most obvious way to make a neck is to start with a chunk of wood big enough in every dimension to engulf the entire completed neck, then simply chip away at the block until only the neck remains. The advantage to this is that there is no joinery to perform and no joints which might fail or look sloppy. More importantly, those who distrust the integrity of laminations, whether structural or acoustical, will opt for this procedure. The disadvantage is, of course, the considerable waste. The waste can be reduced by using a block of wood which will accommodate the widest portion of the fretboard, then adding wood to the peghead through the use of “ears” as in Fig. 1.
