Posted on August 1, 2022May 22, 2025 by Dale Phillips Product Reviews: Knilling Perfection Planetary Pegs Product Reviews: Knilling Perfection Planetary Pegs Reviewed by Randy DeBey Originally published in American Lutherie #100, 2009 By now, just about everyone who works with stringed instruments has at least heard of Pegheds or Knilling Perfection Planetary Pegs. These are geared tuning pegs that look very much like ordinary ebony friction pegs, but work more like fine tuners. They contain a set of planetary gears, which reduce the rotation by a rate of 4:1 for violin family instruments and flamenco guitars, and 16:1 for steel string guitars. Those who haven’t yet taken the plunge and installed a set are probably waiting to have various concerns answered. I’ll try to explain how they are constructed, so you can imagine for yourself how well they might work, and also relate some of my own experience with them. I’ve installed over 100 of the pegs, mostly in violins, but also in cellos, ouds, a banjo, and a guitar.

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?

Posted on January 19, 2010September 9, 2025 by Dale Phillips Questions: Violin Ribs Questions: Violin Ribs by Randy DeBey Originally published in American Lutherie #70, 2002 and Big Red Book of American Lutherie Volume Six, 2013 David K. Kyle of cyberspace asks: I came across a violin made by the JCV Company where the ribs are one continuous piece, and there are no corner or end blocks. The ribs are shaped as if there are corner blocks. It is a little thicker at the end to hold the end pin, the two ends of the ribs are joined to the heel by grooves. The heel protrudes into the body to accommodate the grooves. Is this an unusual method for making a violin? Randy DeBey of Portland, Oregon responds: There was a short discussion of this type of construction in a violin maker’s e-mail discussion group last fall. Apparently, this method was common in Saxony until the mid-1800s and can still be found today in remote places of Finland and Eastern Europe. Not long after the discussion, a violin of this type was brought to me for repair. It had a bottom block and thin wood plates across the insides of the corners to disguise its lack of corner blocks. The base of the neck extended into the top of the body and the upper ribs were wedged into grooves on the sides of the neck base. It was not a well-made fiddle, more of a curiosity. ◆
Posted on January 14, 2010May 28, 2025 by Dale Phillips Review: Baxter’s Database of Violin and Bow Makers v3.0 by Edward D. Baxter Review: Baxter’s Database of Violin and Bow Makers v3.0 by Edward D. Baxter Reviewed by Randy DeBey Originally published in American Lutherie #84, 2005 and Big Red Book of American Lutherie Volume Five, 2008 Baxter’s Database of Violin and Bow Makers v3.0 Edward D. Baxter CD-ROM, 2002 www.violinmakersdb.com. On the rare occasions that I need information about the maker of a particular instrument, I don’t like to spend a lot of time getting it. Due to the ridiculously high prices of violin-maker reference books, I have to get whatever I can from the web, and sometimes that’s a complete waste of time. Now there’s another option that’s less expensive than buying books, and likely more productive than web searching. Edward Baxter of West Camp, New York, has compiled a database from twenty-four violin and bow maker references. He actually started his database several years ago, and the version reviewed here (v3.0) was released in June 2004. It contains information for 19,506 makers. The ViolinMakers Database software was created for PCs running Microsoft Windows (sorry Mac users). It comes on one CD and is easy to install. It includes a stand-alone version of the Microsoft Access database query engine dedicated to searching this database.
