Shopmade Luthier Tools #23: Violin Crack Clamp

06-21-2017 09:19 PM by Dave Rutan | 5 comments »

Last week I found a violin in the bone pile that looks like it’s trying to crack in half lengthwise. Not having any appropriate clamp to hold such a thing together for gluing, I put my mind to it and came up with this clamp. I made it out of 3/4 inch mahogany, using two pieces on each side. I did that so that I could easily create the groove on the inside of the curved parts to engage the lip on the edge of the violin. The groove is shallow so the clamp body won’t press...

Shopmade Luthier Tools #22: Rotary File/Hole Chamfer tool

05-23-2017 12:16 PM by Dave Rutan | 2 comments »

In looking around for the best buys on the tools I actually have to buy versus make to repair bowed string insytruments, I encountered a tool that I haven’t missed having—yet. Seeing that it’s looks like a counter sink bit on a handle, I made one. The handle is a turned spindle that I saved from a piece of furniture for just such a use. I just had to shorten it and drill a hole in one end to accept the counter sink bit on one end. I glued it in with epoxy and...

Adventures in Lutherie #11: Bench Puppy and Tiny Wedges

05-08-2017 07:57 PM by Dave Rutan | 0 comments »

I needed a place to use a chisel to cut small wedges out of maple for rehairing violin bows. The benchtop has a piece of carpet on it and I didn’t want to damage anything anyway. I made a small bench dog to give me something to push against and cut into without worry. It’s made with a scrap of oak that I had. The cleats are just glued on but are holding up fine. The wedge I msade is the small bit of wood with the dot on it just at the corner of the chisel. I believe itR...

Oahu Guitar Restoration #5: An Adventure with the Bridge Plate!

04-07-2017 02:29 AM by Lemongrasspicker | 0 comments »

If you prefer not to read the video is herehttps://www.youtube.com/watch?v=lwLDBA1nQIo So we are now at the most annoying part of this entire restoration and that’s the bridge plate. Here’s a picture so you can get an idea of what and where the bridge plate is. It’s the small overlaid piece of wood A guitar’s bridge plate does quite a few very important jobs for the guitar. To make it simple, the pull of the strings on the top of the guitar is quite intens...

Shopmade Luthier Tools #20: Neck Clamps for Violin, Cello, etc...

04-03-2017 05:09 PM by Dave Rutan | 5 comments »

There are at least two instruments in the shop that need necks reattached. I was shown how to do this when the entire neck is detached, but two cellos are broken at the joint and the method shown me might not work so well. Google to the rescue! I found photos of commercially available models, selling for multiple tens of dollars, and decided I could make my own. I used some of the mahogany at my disposal, some 3/8 in. threaded rod, and some sheet cork I was given a few years ago. ...

Shopmade Luthier Tools #19: Small size sound post setter

03-27-2017 08:02 PM by Dave Rutan | 4 comments »

I already own two violin size sound post setting tools which I purchased online. The other day I was setting a sound post in a less than full size instrument and I got the feeling I was stretching the limits of the tool. I got the post set successfully, but it entered my mind that a smaller tool might be handy for if I should have to work on a 1/4 size violin or smaller someday. So today I went down into my woodshop, took a piece of 1/4 iinch flat brass and went to work with the grinde...

Oahu Guitar Restoration #4: Crack Repairs and Top Reinforcement

03-21-2017 01:00 AM by Lemongrasspicker | 6 comments »

If you prefer not to read, the youtube video is here https://www.youtube.com/watch?v=WmXWgNwtXAg For this session I started to repair and reinforce some of the bigger issues with this guitar. All guitars experience a tremendous amount of strain and pressure on the neck joint at the body. A good way to counter this strain is to reinforce the top in the area just below the fingerboard. This guitar did not have any reinforcement in that area and thus it was necessary to add some stiffness ...

Oahu Guitar Restoration #3: Removing the Fretboard and Neck

03-06-2017 04:45 PM by Lemongrasspicker | 0 comments »

Video is here if you prefer not to read http://www.youtube.com/watch?v=5lZ1XroRf8o&feature=youtu.be Part 3 of this series is a simple prospect of removing the fret/fingerboard (they’re different names for the same thing) as well as the neck. The traditional joint for a guitar neck to be attached is a dovetail, this one was no exception however it was extremely poor in it’s execution (not surprising considering the number of these they made and the budget they were mad...

Adventures in Lutherie #9: How to rehair a bow

03-01-2017 05:23 PM by Dave Rutan | 1 comment »

You might not realize this, but all musical instruments occasionally need maintenance. Brass instruments may need a new spring in the valves, pianos might need new felt on the hammers, or a woodwind may need new cork on the stops covering the holes. For the string instruments probably the most frequent maintenance is rehairing of the bow. The horsehair actually wears out from use and an unused bow, kept in its case may succumb to an infection of bow bugs that break the hairs off. Part ...

Oahu Guitar Restoration #2: Removing the Back

02-27-2017 02:39 PM by Lemongrasspicker | 3 comments »

Video entry is here https://www.youtube.com/watch?v=u3G8GxAHNmY The first step on this long project is to remove the back of the guitar. The reason we are doing this is two fold, there is a tremendous amount of work that needs to be done to both the back, sides, and top of the guitar. If we were to try to do the level of work that is required through the soundhole we would be far too tedious and would end up with a poorer result. Removing the back allows me extremely easy access to all ...
