I recently picked up a Sterling Atlas 12 string that is in excellent shape except for some bellying, which once I get into setting action, may determine if I need to add a ‘bridge doctor’ to remediate some of it. However, I noticed that the saddle (adjustable but set to lowest point) has no curvature and there is not much down pressure on the center sets of strings which is causing some buzzing. My question is this (my first 12 string p…

Thanks again to those that lended their wisdom. Bridge doctor just came in plus some bone saddle blanks so will get ready to tackle that project in near future.
when setting up acoustic guitars, from time to time I have a lot of trouble with getting the G string to ring true when fretted. Starting from lower frets and at its worst at about the 5/6th fret, the G string buzzes when plucked "heavily" (when no other string does so)...most recently a Taylor 724 which had a neck adjustment to reduce action (to 5/64-4/64), relief about 0.003 or 0.004. Increasing relief to about 8-9 helps somewhat.…

Depends on what you are calling a "buzz." The G3 at 196 Hz is going to be very near the T(1,1)2 main top resonance of the guitar. Notes fretted up higher on the G string could conceivably be near th…
I've only built a handful of necks and most of them have been roasted maple fretboards. This time around I am using a beautiful and incredibly stiff/hard piece of ebony. I am doing a light hammering in of the frets to get them seated and then using the hand-held vice clamps from Stewmac with the correct fretboard radius to push them down evenly the rest of the way. This process works just fine on roasted maple. It's just a softer wood t…

Thanks all. I widened the slots with a bigger blade and deepened them a bit. It's to the point where they kinda slide in and I'm using CA glue to get them all the way there. Hammering them in just doe…
I inherited a 70's D28 that is a players instrument. The action is too high for me, but the saddle is bottomed out. There is no obvious belly bulge. The top of the bridge has been shaved. Bridge pin holes are uneven in diameter. However, the bridge placement seems pretty close; within 1/32". A straight edge on the fret board sits about 1/8" below the top of the bridge. The fret board has plenty of finger worn wells, there is virtually n…
Looks like classic neck reset/typical martin stuff. Only exception is the fingerboard. Might be worth hopping on a zoom call to chat about this one. Would you have time for something like that ?

I'm refretting an all-original Gibson L-7 from 1934, and it has a 9.5" or so fretboard radius. However, the bridge, also original, has a 12" radius. I need to flatten the board, as it has a hump at the tenth, but I'm wondering if I go with the 9.5" radius, or try and get it to 12". I'm a little worried about sanding through the Nick Lucas style inlays, so I'd like some input here. If I kept the 9.5" radius, I'd likely have to radius the…
It's probably going to make sense to keep the 9.5 radius. You'd definitely have to pull the inlays to modify the radius that much in the middle of the board and that would really suck with those inla…
Hi Everyone, I’m working through building my first set neck electric, an LP Jr. I had some build questions… - if you’ve built these Gibson style set necks before, did you cut the neck pocket straight and angle the heel of the neck? Or did you cut the pocket at the angle and keep the bottom of the heel straight? I’m attempting to cut the pocket at an angle, and it isn’t the easiest thing to do, I’m finding out. First, I’ve had some moveme…

Hi Joe, I would recommend putting the taper in the neck pocket, not the neck. Maybe you need thinner shims to solve your router depth issue. I would glue the fingerboard onto the neck and have that as…
Doing some workshop organization and found some tools I don't use. All are in excellent shape with very minimal use. Each item linked to the relevant product page: Japanese nut files. Mine have a bit of surface rust but they were used for maybe 2 guitars. $80 new, selling for $40 StewMac Gauged Nut Slotting File Set for Electric Guitar (for medium strings) and one of each nut file backer. Used on one guitar. $113 new for the files and $19…

Hello everyone, I'm currently radiusing out a flame ebony fretboard (using 100grit sandpaper), and is giving me some trouble. The radii is 16'' and it came perfectly straight along its lenght, but over the width, tough the radius already match the sanding beam, it keep developing along the lenght 2 long areas were it seam to eat more wood than other parts, leaving a gap easyly noticeable under inspection. At first I thought that since th…
My prime guesses are heat or funk in the radius block. If you are using epoxy to glue the FB on, you might switch up to hide glue. It has better resiliency to heat unless you pony up for hi-temp epoxy…

Hello, This is my first discussion as I am new to this group. I am starting a restoration project on a 1957 Gibson LG-1. The first job on it that I want to tackle is to replace a broken back brace. It appears to be broken in half right on the center line (see pic one before the brace was removed). I have removed it and am gluing in back together (pic 2), just to get it strong enough to use as a template for fabricating a replacement…

Hi John, welcome to the Looth Group. Yes, Doug Proper's radius-sanding tool is wonderful - he should have invented it 50 years ago, and that really annoys me. However it is one of the most "why din't…
I've been Loothing for around 10 years in busy shops in the Seattle area (Mike Lull's & mike and mikes guitar bar) and went out on my own in a home shop a little over a year ago. Just this month moved into a new repair space and showroom for my custom guitars, which was the largest driver of the move. Having a good space for people to play my builds seems pretty paramount. My regular customers that have been plenty of income over the p…
