Cascadia in BC will do customized fretboards. They haven't carried much stock lately but it's maybe worth an email. If you go to any blank they're selling, at the bottom you'll see they offer custom C…

Experienced Builder and Red Wing Grad

Howdy folks, I'm a 2026 graduate of the two year guitar program at Red Wing (Minnesota State College Southeast). Between my two years at Red Wing I worked at Collings Guitars in Austin, TX for two years in the acoustic neck department, shaping and finish sanding ~2000 necks, radiusing and gluing ~750 fingerboards, and pressing ~100 sets of frets. I also spent a couple months in the finishing department level sanding and pore filling ~300…

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…

Nominal Normal Thickness of Barb Thickness for a .022” Tang Wire?

Let me start with this; I'm trying to find the root cause of difficult fret wire installation of two different SM fret wires. I've spent a lot of time gathering dimensions and experimenting with techniques wich could cause the problem. I enlisted the help of a colleague who arrived at a similar poor performance. His solution was to glue the fret ends/ beat the frets in. My "rather" is to find the root cause so I don't have to go thr…

Matching the fretwire to the fret slots (and visa-versa) is a huge subject. Dan and I did an entire episode of the Dan and Doug Show just on fret slots. I'll be revisiting the subject of fretwork in…

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,…

Measured drawing and assembly for Proper Variable Radius Sanding Jig

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…

Cupped panel

I have a set of bubinga for an acoustic back, but one piece had a slight cup that made it difficult to work with for joining together. This is pre-thicknessed, with the piece at 4.5 mm thick. I tried wetting and heating it, as I do for sides, and pressed it flat during the process. I heated it to 300 degrees F, and then let it cool while pressed, and the cup got substantially worse. I then pressed it into a reverse cup using a radius…

To get the nice figure in Bubinga, ordinarily the board is flat sawn. That greatly increases the likelihood of cupping. If you are able to flatten out the cup enough to joint the 2 pieces and thickn…

Any helpful tips with bar frets?

Hello, One of my commissions is coming down the pike and it's going to be my first time using bar frets. I could use a once over for any helpful tips if you have any. About the guitar: Aged HD-28 but mahogany back and sides. I think Martin called this a HD-28 M? Skipping the truss-rod and using two carbon fiber strips. My process for Frets: 1: I CNC my fingerboards to a 16" radius and for T-frets I use a .023" to cut slots with a mat…

Depending on the carbon fiber strips and the gauge of string, you're compression may be moot, or at the very least, a fairly subtle factor. I would do a lot of testing before you glue the neck on to t…

Cutting Fret Slots

I cut the fret slots for a baritone guitar build today, so I thought I'd share my method for cutting fret slots, as I think it is a bit unusual. I radius and profile my fretboard before I cut the slots. I print out a paper layout of the fretboard, double-stick tape it to the radiused and profiled fretboard, line up the saw by eye to using red hatch marks on the printout, and saw the fret slots with a 3" circular saw that rides on…

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…

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.

Nut slot and action trouble

Hi everyone - I recently ran into trouble making new nut for one of my necks that needed to be trued and re-fretted. I roughed in the nut as usual and then, with the bass guitar fully assembled and strung up, I started cutting the slots to depth. I use the StewMac digital nut slot depth gauge and have had good results in the past. I marked the nut's lowest points (radiused) using the guitar nut scribe tool (first time using this!) and c…

That's actually not how that tool was intended to be used. That is essentially plotting a like to the top of the fret. With a bass, you would need much more than that. When James and I came up with th…

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…
