Shop-Made Bandsaw Dust Port

Shop-Made Bandsaw Dust Port

by John Calkin

Published online by Guild of American Luthiers, September 2021

 

My old bandsaw was made before dust ports were added to every power machine, so I made one out of wood. It's a close copy of the heavy-gauge steel cover for the lower wheel but made out of light plywood. The dust port itself was purchased and screwed to the cover. A mahogany interface to accept the 3" vacuum hose was made to fit the port. The sides of the cover were kerfed to permit easy bending to match the original metal cover. I think the rest of the construction is self-explanatory. ◆

The Paul Schuback Story

The Paul Schuback Story

from his 1986 GAL Convention lecture

Originally published in American Lutherie #9, 1987 and Big Red Book of American Lutherie Volume One, 2000



Paul Schuback was born in Barbados in the West Indies in 1946 and moved to the United States at the age of nine months. Through his experiences and training, he lived in thirty-three different homes before the age of twenty.

His interest in musical instruments began when he was quite young, when he took up the violin at the age of seven. At the age of nine he began playing the cello, joining a youth symphony orchestra in Utah at the age of fifteen. Then, before graduating high school, he began his career as a luthier with a three-year apprenticeship to master Rene Morizot, in Mirecourt, France. Following this, he specialized in violin making in Mittenwald, Germany. He then became a graduate in bow making at the Morizot Freres again in Mirecourt, France. He continued his studies by researching historical instruments in France, Germany, Switzerland, and Italy. From 1968 to 1971 he worked as journeyman in the Peter Paul Prier violin shop in Salt Lake City, Utah, before moving to Portland, Oregon, where he established his own workshop and where he resides today.

Bending Sides with Silicone Blankets

Bending Sides with Silicone Blankets

by Michael Keller

from his 1990 GAL Convention workshop

Originally published in American Lutherie #25, 1991 and Big Red Book of American Lutherie Volume Three, 2004



Althrough I attended the 1977 Guild convention in Tacoma, I exhibited my instruments for the first time at the following year’s convention in Winfield, Kansas. I visited Stuart Mossman’s shop while I was there, and I saw the side-bending mold that he had. It must have cost a fortune. It was about the size of a Volkswagen van standing on end, and it had all sorts of hydraulic pumps and pistons. In a production shop that kind of tooling might make sense, but for a small shop like mine, making twenty to thirty instruments a year and bending wood for repairs, I don’t need that kind of investment.

I bent sides for years over a hot pipe I bought at Lewis Music in Vancouver, B.C. I had to work at a regular job and save money for quite a while before I could afford to buy two Overholtzer side-bending molds. A friend of mine had a custom mold made by the Overholtzer company, and it cost $1,000, I believe. That’s a lot of money. I can bend guitar sides with either a hot pipe or a cast mold quickly and accurately, but I am in this to make a living, and if I can save time and money I will do it. That’s why I prefer my new method. By the way, would anybody like to buy two nice Overholtzer molds?

Lute Rib-Cutting Jig

Lute Rib-Cutting Jig

by Robert Cooper

from his 1984 GAL Convention lecture

Originally published in American Lutherie #4, 1985 and Big Red Book of American Lutherie Volume One, 2000



The lute I brought with me today has a half-round cross section. In such an instrument, each stave is identical in size and shape to its neighbor. A set of these ribs can be cut quite efficiently on a jig I made for use with a router fitted with a small circular saw blade.

The main section of the jig is a solid wedge of wood, like a slice of apple. Or more like a slice of a pear.

Ren-Shaped Precision Mold Material

Ren-Shaped Precision Mold Material

by Ed Beylerian

Originally published in American Lutherie #21, 1990



The demand for ever-increasing quality in end-use products has generated a concurrent need for improved modeling materials. Patterns and molds constructed from traditional materials such as laminated wood and plaster cannot maintain the precise tolerances required by model makers in the automotive, aerospace, foundry, and prototyping industries. With Ren-Shape 450, models can be built with a more stable medium, using precision numerically controlled (NC) machining equipment.

I obtained a 2"×16"×60" board of Ren-Shape from Ciba-Geigy corporation, as well as the laminating compound and the repair kit. Ren-Shape is about the same hardness and density of a medium hard wood, and a tan color. The setting time of the two-part laminating compound is easily controlled by the amount of hardener used, and can range from one to six hours. The repair compound sets overnight.
