Skin Heading Ethnic Drums, Etc.

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.

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”.

Grading and Resawing Lutherie Wood

Resawing Lutherie Wood

Harvesting, milling, and processing tonewood can be a wasteful business. Much of the wood used by luthiers comes from large, older trees, elders worthy of respect. As someone fortunate enough to work with these rare, high-grade woods, one of my top goals is to minimize waste by processing this valuable resource efficiently.

This article concerns the Hitachi CB75F resaw, though much of what follows is general enough to be applicable to other resaws. Luthiers who buy resawn sets might glean information about how their wood is processed and what to request or avoid when ordering.

A note on nomenclature: A resaw is an upright or horizontal bandsaw set up to make uniform rip cuts. The front of the saw is where you start feeding a cut. The face of a board is its wide, longitudinal surface; the edge is its narrow longitudinal surface; the end is its crosscut surface. The resaw blade is made up of its band and its teeth (terms not necessarily interchangeable). I refer to vertical-grain wood in place of quartersawn wood to avoid confusion, since a sawyer can get vertical-grain cuts without quartering a log.

Stewart-MacDonald

At the ’99 Merlefest in North Carolina I had the good fortune to find myself manning a booth next to Stew-Mac. It was a pleasure to meet Todd Sams and get to know Jay Hostetler better. It was also astonishing to hear so many self-proclaimed luthiers confess that they had never heard of Stewart-MacDonald. Where do these luthiers buy their tools?

My guess is that they aren’t buying them at all, that what they can’t find at Ace Hardware or cobble together in the shop they are doing without; that they don’t even know about the tools that could make their work better and their lives easier.
