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…
Hi all, I'm new here. I've been playing guitars for ~15 years and recently started as a technician at a music production school in London, where part of my job is maintaining the guitars.
I picked up this 50s parlor nylon the other day and it's in bad shape but I don't know how to go about repairing it.
The main issue is the bridge. The guitar was kept high strung and the bridge has twisted and lifted off slightly at the base. T…

So now put the iron on low, heat the bridge for at least 5 minutes, then take it and the insulating cardboard off, and see if you can begin to work palette knives under the bridge. If it's not relativ…
Hello all, got a problem in a telecaster I rewired that has me in a twist. The basics: friend has a 2001 US Standard telecaster (left handed not that it matters). He bought it used and says it was quiet initially. A few years back he grabbed the pickups out of it and moved them to a new tele body with a torrefied maple neck he preferred. Recently he upgraded the new build with a Lollar CC tele set, and asked me to reinstall the original…

Well, another update: I rewound the neck pickup, and flipped the polarity, so now the set is RWRP. Everything wired back up, and when the pickups are in series (position 4), it's dead quiet. The buzzi…
Has anyone removed the stabilizer bar from a Fender Wildwood Acoustic guitar? I need to repair the bridge area and I cannot figure out how to remove the internal stabilizer bar. Any input would be appreciated
I have repaired numerous top crack on this instrument built by a customer at a guitar building camp. The bridge was off and warped. That has been addressed. After gluing with hide glue and splining the crack these top two did not closed as much as I would have liked. The bigger is about 1/32 at the widest and the other about 1/64. The crack is tight at the bottom. If I can help it I would like to fill it rather than spline it as I have…
I am pretty good at touch up on darker to med woods and air brushing some solid color touchups on electrics but as you said spruce tops with gloss are near impossible. I was hoping to maybe clean it…
Hey all, Anyone have any go-to methods for making new replacement bridges look old? I’m about to make a new bridge for a relatively beat up 40’s Martin and contemplating ways to make it look more the part. With the replacements I’ve made up to this point I’ve always just sanded em real smooth, micromesh, oil, wax etc. I’m thinking maybe a wire brush prior to sanding for that shrunken grain look? The new bridge will be Indian rosewood. T…

You can try raising the grain a little with a damp paper towel. I wouldn't got too wet. Mirlon 2500 pad is my go to for knocking down the sheen. Add dents to your liking. Find a reference photo a…
I have a 74' D-28 im working on, just curious what you guys do in terms of process steps. Right now, im setting the angle, without frets(I reinforced the square tube rod with carbon fiber and will need to refret once put back together.) Do you guys shoot for the straight edge hitting the top of the bridge with, or without frets? Im wondering if I should undershoot my bridge just a touch so that then I can fret and have a good saddle hei…
Hey everyone, recently I've been getting more requests for neck resets from customers, and up until this point I haven't been offering them since I don't have the practical experience. I'm keen to change this, and I've borrowed my fathers Harmony H167 that has seen better days. I've done an initial cleaning and assessment, the truss rod works although I may need to force it into a backbow to have a fully adjustable neck. This shouldn't…

Also you have to take into account how much flex the top has. If you could set the neck dry then clamp it and string it up you can start the calculations about how much you to take off of the heal. In…
I recently picked up a used custom guitar that the seller said he bought in Vietnam Nam many years ago. I bought it as a wall hanger due to the wonderful Mother of Pearl work, especially on the back. It was very apparent that the top on this instrument was sunken at least 3/8 of an inch, as the weird bridge setup was heightened to the max and there was barely any action height. Once I took it apart and removed the foam inside, I was…
I saw this advertised on the web and was interested in it as I had never seen a bridge like it before.. Just curious, thought some of you might recognize it..
I had a bridge replacement in which the top surface (laminate) had been badly damaged during a prior repair. The first picture shows the extent of the tear out, including one large area and many smaller defects in the top layer. The surface was cleaned of all the old glue and primed with dilute hide glue. A piece of poplar veneer was glued in the largest defect and a hot slurry of hide glue and fine poplar dust was spread across the res…
Hello,
I have on my bench and es-125 with a concaved belly in the top where the bridge sits, I was able to fit a feeler gauge under one of the braces in the area, the brace above the bass side.
The back of the guitar is loose for a stretch of roughly 5 inches.
My thought was to take off the back and address the braces and somehow address the warp in the top.
Any thoughts on how to unwarp it or better approaches to the whole job?…
can anyone help me determine the neck angle on a 12 fret to the body neck Robbie Obrien says the gap betwwen the plane of a 14fret neck and the top of the soundboard at the bridge should be3.5 mm. does that hold true for 12 fret necks

The 3.5 mm elevation is fine, but the point where you measure the 3.5 will be slightly further back on the top (the distance between the 12th and 14th frets). Assume you want a 14 mm string height.…
