I am repairing a damaged Stella parlor guitar. The original top was birch, plain sawn at 0.100 inches thick, ladder braced with multiple beefy braces and irreparably split, warped and generally separated from the sides. I want to keep the instrument ladder braced with a movable bridge and upgraded tailpiece, all firsts for me. I would be grateful for input on 2 issues. 1. The new top is Adirondack spruce that I’ve reduced to about 0.110…

Hi there! Working on a Squire Vintage Modified Jag. relevelled and crowned the frets. Lovely job. Set the relief and action to factory spec. So far so good. With a capo on the first fret, I set the string radius at the saddles to 9.5" using an under-string radius gauge, everything lined up nicely... ...but when I measured the action of all the strings along the 14th fret using my digital nut slotting gauge (expecting a unifo…

Hi all, new to nut slot work world, please can you help me with this mystery? fret levelling, neck relief and string action adjustment all completed to Fender 9.5" radius spec. very happy with that. the next step: 0.011” High E string’s nut slot was a bit low. I used Dave Johnson’s (MI Guitar Craft Academy) “q-tip slot raising method”: the pulled cotton strand, plus extra thin CA glue, to fill the slot, then trim it off once dry,…

Doug Proper designed a sanding jig that supports variable concave and convex curves, described in the following Loothgroup article: https://loothgroup.com/post-imgcap/the-variable-radius-sander/ I built one and am impressed with how it facilitates preparing bridges, braces and also allows tracing any radius using the chord formula. I made a rough measured drawing and assembly guide to share, with Doug's blessing. First step, ma…

Hey everyone, I wanted to do a bit of a follow up on a repair I'm doing. A customer brought in a Seagull acoustic guitar that had been dropped, causing the heel block to separate. I managed to get that glued back together with pleasing results, however I did need to take the neck off by removing the two bolts which thread into the heel block, and unglued the fretboard extension. All went well here, although I'm left with a situation whe…

Does anyone have a vintage Gibson LP Special around to check the body edge radiuses for me? Is it a consistent 1/8” (or so) all the way around the entire top and entire bottom? Including the horn, ledge behind the neck heel, etc? Thank you! This 56 seems pretty consistently rounded over across the entire top and back.

Working through my first refret. Trying to straighten the neck before radius sanding. What should the natural relief look like when straight? Using a straight edge there’s always slight gaps somewhere. Does natural neck relief start at a certain fret?

Hey! I have a friend who builds flat tops who wants to give stainless a try. I have done a handful of refrets and he was asking advice. He is using a compound radius from 14” to 20”. Jeskar sells the coils and they come in 10”. I have only done installs where the wire matches the board precisely. I bought pre cut pre radius bags for these re frets. Has anyone worked on a compound radius. Do you radius each fret on a bender or can you get…

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…

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.…
