Dana, I've had a devil of a time using go-bars with lute bracing. Lute braces are narrow and it's difficult to position the go bar so it doesn't flip a brace over. If the pressure is even a little bit off-axis, there goes your brace. I would imagine it's different with the wider bracing

Chad, Well, it's a small anvil. About a foot long. A blacksmith's anvil would definitely be overkill. I haven't actually glued on all of the braces at one go yet, but I think I may try it on the next instrument I build. It does sound like a bit of a circus act, though. Re-gluing bridges

R, My go-bar box is a four foot cube (plywood top and bottom with threaded rods in the corners holding them apart). I've cut the foam core so that three sides are solid but the front opens from the middle, which makes it less cumbersome to get into. The foam core pieces are held together by

I'm an amateur also, but isn't the pitch determined by the density and breaking strength of the string as well as its length? And, of course the response of the instrument is determined by a number of factors, including volume of the bowl, size of the rose, and the makeup and bracing of the

Ben, Speaking as someone who has done a great deal of archaeological illustration, I think you need to understand that technical drawings are made for specific purposes. Every drawing represents the artist's idea of what is important to include and what can safely be left out. And has an

Does anyone have a good method of planing or smoothing the edges of thin ebony strips to go between ribs? I've bent wider pieces of ebony to the right shape and sliced off thin strips with a band saw. As I cut each piece I could hand plane the cut edge on what was left, but as a

From my one very brief but unforgettable experience with it, it smells worse than bone when cut with power tools. Don't do that in a confined space. I once needed some antler for an educational display and went to a taxidermist. When he cut a piece for me on the power saw in his garage,

Hi Alexandros, You need a wood that is wear-resistant and also fairly fine-grained and dense (to efficiently transmit vibrations from the strings to the soundboard). I would think that beech would actually work well. You could stain it black if the pale color is a problem (just don't stain

Christopher, Spacing depends partly on the size of your hands. The spacing on actual Renaissance lutes is fairly tight. I have large hands and have a hard time playing a lute with spacings that are historically accurate. The ones I've built have a wider spacing based on what Daniel Larson

Hi all, I might add to Dan's explanation that a single jig can be used for lute bowls with differing numbers of ribs. My one jig is set up to produce bowls with 9 ribs or with 13 ribs. The pivot point stays the same; you just have two sets of indexing points. So far I've only used it to

Hi all, On the last lute I built, I used Daniel Larson's method, which he demonstrated in a workshop at a Lute Society conference several years ago. He doesn't us a a form at all. He has a jig that you bend a rib around. After the rib is bent, it stays on the jig, which can pivot up and down

Hi Dan, I am definitely interested in attending the workshop. I'll look forward to it. I've tried to take the philosophy into other tasks in lute construction, too. I use a masonite template and a Luthier's Friend to template-sand a lute bridge most of the way from a blank to a finished

Michael, I guess I don't see the point of continuing the endclasp that far. I've only built a handful of lutes, but I've handled and repaired several others, and I haven't really seen much of a problem with the belly separating from the bowl along the sides. If hide glue is used it is easily
