Retopping a ladder braced Stella - dimensional questions

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…

I don't have much to add but I am working on the exact same guitar at the moment and had a question. How did you get the neck off? I'm doing one of my first few neck removals on this and it isn't seem…

String radius at bridge & at 14th fret are totally different??

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…

If you adjusted your truss rod and action to factory spec, then you adjusted the radius at the bridge, you changed the string action height. I know some will set the action on both e strings and then…

Open string sitar buzz after nut slot work

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,…

i always use a nut file that is the closest size up from the string gauge. i used a 13 gauge file for an 11 gauge string, and 16 gauge file for a 14 gauge string

Seagull Acoustic Neck Reset...

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…

One other issue with the guitar that I wanted to mention was a fairly sizeable split in the back. At its widest, there is a gap of about .015" and I'm curious to know how you all would handle this? I…

Is edge roundover on Gibson LP special the same all the way around the body?

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.

Neck relief without strings?

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?

Natural neck relief without strings sounds...not good. Most necks aren't stiff enough for the need to add relief without string tension. Said another way, string tension is almost always enough to give…

Stainless steel fretwire for compound radius

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…

Newbie question on 12 string action

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.

Frustrating Fret buzz

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…

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…
