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…
Hide Glue Working Time
I'm using hide glue on this 1st build. So far I've glued up the kerfing, back braces, and the top "X" brace. I'm using the 190 grade glue. Working time is short at best. I heated the top "X" brace surfaces (brace & top) with a blow dryer and that seemed to help, a little. How can I get enough working time to glue the top, and then later the back, without having to rush and creating a real mess in the process? Suggestions and reco…

How would you tackle this airline damage repair?
(Just to set expectations, I bought this for the sole purpose of learning. Not a client project) I got this Martin D28-12 in destroyed condition, after an airline did something awful. As I see it: - Top cracks - Back cracks - Top & side separation with some broken off kerfing - Brace ejected When I was looking at the pictures online pre-purchase, I thought I might take the neck off and re-top it, or at the very least, take the top off and fix…
Warped x-brace on Gibson L-3
I watched the Guild F-20 video (https://dev2.loothgroup.com/groups/repair-and-restoration/forum/topic/cracker-x-braces-on-guild-f20/#post-60310) with great interest since I've been working on a Gibson L-3 with a similar problem. A little back story - The original repair request was to address a small pickguard crack on the sound hole side. After peeking inside, I saw 5 loose brace ends on the treble side. Still a pretty standard repair…
Upper Bout Soundport
What support or bracing is common around a soundport that is placed on the upper bout at the edge of the instrument, where the lining or kerfing typically holds the guitar together? I've been able to find info on direct top or side upper bout soundports, but I haven't had much success when looking for the support structure once you've cut into both the side and top. Any resources or tips would be appreciated.
Weissenborn Top Separation
I had a very unique instrument come into the shop yesterday. It's an American built Weissonborn/lap guitar (*spelling). The top has separated from the kerfing and sides on the lower left bout, and was raised significantly while under string tension when the customer dropped it off. I have a two fold problem as I see it. Applying horizonal pressure to a very light and fragile instrument, and getting enough glue into the separation where…

Fretting table saw setup
This is a simple but effective setup for cutting fret slots quickly and accurately. Ryobi table saw with a crosscut sled and saw blade with a kerf to match fret slot thickness. The sled has an indexing pin for using fret scale templates with notches. The blade alone sells for $163 on Stew Mac. I also have another blade for sale.

File Fixture for Letting in Braces
Brace Brace
Hey friends, just wanted to share a thingy I made and have been finding very useful for a couple years now. Ive intended to remake it prettier ( former helper did the file work), but this one works fine and I'm busy. I call it the Brace Brace. It hugs a length of the loose brace, and puts nice pressure across the brace, but most importantly on the scalloped end against the kerfing. I loosen one side of the other, then tighten it in…
Double Sides?
I recently put a strap button on a 2023 Woolson Soundcraft (Paul Woolson) guitar, and had a look-see inside. It has a sound port, and the sides are about 3/8" thick. There is no kerfing, the back and top appear to be glued to these thick sides instead. The web site says it has a "double top". Anybody ever hear of double sides?
