54' SJ-200 Bridge replacement....

Well, I have exhausted all the internet can offer for options for a replacement bridge. The customer, long ago, removed a ton of material from the bottom(!!!!) of the bridge, and now that ive taken this guitar on as a restoration, its up to me to make a new bridge. I have found some ultra small pattern bits, and round-over bits to do the inside of the mustache flush, but I can not for the life of me decided how im going to cut the bulk…

Hey Jonathan, PM me. I have a moustache model (even though I don't particularly care for them!) and I might be able to help you out. I'll need the desired material for the bridge, X, Y, and desired…

Warped x-brace on Gibson L-3

I watched the Guild F-20 video (https://dev2.loothgroup.com/groups/repair-and-restoration/forum/topic/cracker-x-braces-on-guild-f20/#post-60310) with great interest since I've been working on a Gibson L-3 with a similar problem. A little back story - The original repair request was to address a small pickguard crack on the sound hole side. After peeking inside, I saw 5 loose brace ends on the treble side. Still a pretty standard repair…

That move of 3D printing the taper you want and running it through the sander to make a copy just blew my mind! Thanks for sharing Dave!

Belt sanding headstock repair

Has anyone ever used the belt-sander spline process for a headstock repair? It’s when you glue up the headstock then push it up against the rounded edge of a belt sander to remove a rounded chunk of wood, then patching the chunk by sanding down a rounded spline to fit it. Seems much easier than routing channels because you can put sticky sandpaper directly on the sanded-portion of the headstock/neck and shape the spline perfectly to the…

I do it that way minus to belt sander. If you think you can produce the same cut, I don't see why not. I just always wound up doing it on guitars where the risk of errant sanding would have been tragi…

1950 Martin D28 with localized scary thinning.

Hey all. I've got the above-mentioned guitar on my bench. It had a neck reset and what appears to be a new bridge pad put in 14 years ago. It's a crack-free guitar except for a couple of little hairlines running from the back of the bridge to the upper tone bar. I thought that was a bit weird. Inside, everything looks okay until I turn off the inspection light, at which point I can see the rosy glow of daylight through the top - this…

In classical woodworking theory, yes - crossgrain glue-ups are a real no-no, but we get away with it in guitarmaking all the time. We're the rebellious bad boys of woodcraft! In this case I went w…

Fretwork Processes...

Hey everyone, I could use some advice as far as the fretting process is concerned. I’ve been doing guitar repair since around 2008, I opened my business doing guitar repair in September of 2021, and I’ve always felt that fretwork has been the most challenging part of this job. I’m getting to the point now where I finally feel like I’m getting the hang of it, but I’m not where I want to be yet. I should mention that I use the Erlewine…

Hi David, I'll throw my two cents in here. Rather than go through my thoughts on the entire fret level and crowning process, I'll toss some of my observations in. Firstly, if you haven't watched it, I…

Trying to pass on the love

Hey everyone. This is a first time post for me, but I wanted to say thank you for everything. I’ve been tinkering here and there for the past few years under the eye of a former Martin employee, but this group has really given me more courage. In a high school math teacher by day. I teach mostly Geometry and Algebra. One of my students stayed after for help the other day and had his guitar for guitar class. I asked if I could see it and i…

That’s a great story. You are the man! That kid must have been blown away. And now there’s one more person out there that guitars can actually be worked on and set up. As opposed to, it came from the…
