Seeking Mid 70's Martin D28 High Action Assesment Input And Recommendations

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 ?

1930s Gibson L-7 Fretboard Radius 9.5" vs 12"

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…

Set-neck pocket and angle questions

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…

Trouble radiusing ebony

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…

Replace broken back brace Gibson LG-1

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…

Driving people into a new shop

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…

Advertising

Anyone ever done any advertising? What things did you highlight? We've got a videographer in our shop for two days next week to record. We are doing several short social media ads and one longer video that will live on Youtube. We have a great local following, but plan to target a 100 mile radius. WE regularly get people driving that far. Curious what you've learned were good things to focus on.

Just got these and they are really neat. If you like to press frets and do compound or imperfect radius fretboards, these are the ticket.
