If you’re using 0.040" stock, this technique breaks a lot of inlay. I’ve had great success using white glue in very small amounts (about three tiny dots on the back of the piece). Let it dry, then scribe with a machinist’s scribe or a #11 X-acto blade. Pass a lit match across the top of the piece and warm it thoroughly. This will break the glue bond and allow you to slide the inlay off without harm. The glue remaining on the fingerboard can be easily cleaned off, and you can go from there. I’ve also found it helpful to rub the scribed lines with a white or yellow grease pencil, and then wipe off the excess. This leaves a very fine line which is also easy to see. ◆
Posted on March 4, 2020May 20, 2025 by Dale Phillips Violin Top Removal Violin Top Removal by George Manno Originally published in American Lutherie #5, 1986 and Big Red Book of American Lutherie Volume One, 2000 One of the most difficult repairs to perform on a violin is removing its top after it has been glued with a yellow or a polyvinyl white glue, such as Titebond. These glues do exactly what the name implies: Their main objective is to close the separation between the rib and the top or back permanently. Violins are built in such a way that they can be taken apart if necessary. On many occasions, we have seen instruments come into our shop that were repaired by amateurs using whatever glue was available at the local hardware store. Apparently, thoughts of future adjustments to the neck or bass bar are not considered. Efforts to remove the top without damaging it after such glues have been used were, for a time, a cause of great distress to us. We have found a way to dissolve such a bond without harming the table, ribs, or back. Using a number of thin artist’s spatulas, a syringe, and some warm vinegar, along with a lot of patience, the removal of the top can be done successfully and the repair completed in a few days.

Posted on January 6, 2020May 21, 2025 by Dale Phillips Devolution of the Modern Lute Devolution of the Modern Lute 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 other way to do it is with a dovetail extension on the neck, which slides into the block. But that is not really the historical way. Here again, we’re getting back to the historical method, and it seems to be perfectly adequate. It is common in old lutes to use no tail block whatever. Also, a lute has no edge binding or lining; the top is simply glued right to the rib. The bracing of the lute top is almost entirely composed of transverse bars, with just a J-shape bar and two smaller bars behind the bridge. The transverse bars run directly across the instrument and are butted and glued directly to the sides. The grain of those transverse bars is horizontal; it runs parallel to the top. You may wonder why in the world didn’t they do it logically, like guitar builders, and run it vertically. The probable reason is that when you make a lot of lutes you have a lot of top wood left over from pieces that you broke. Vertical grain top scraps would make horizontal grain braces. Also, if you split braces out of a billet, they split better this way than otherwise. These braces are rather high. The main brace is a little over an inch tall, by maybe 5MM. They are quite substantial, so the fact that the grain runs flat does not pose a strength problem.
