feedback on Les Paul Headstock repair

I need some suggestions from the many great repair senseis out there.The customer is fine with a structural repair and not concerned about making it invisible. I told him you will see anything I do. He was fine with that and has a budget of between $700-1000. It's a clean break. nothing missing, It closes tightly.. I was thinking either 1) the generic double splines one on either side of truss rod and touchup as best I can. Or 2) the ab…

With a break like this with plenty of surface area, I would just glue it without any additional supports. My glue of choice is hot hide glue, but there will be lots of opinions on that and many option…

Returning to Instrument Building Soon.

Hi All, I wanted to check in with folks in the industry and ask for some advice. I have been on a building Hiatus for a number of years now (Hand Injury, Medical Issues). Things have gotten much better, and I am fully able and capable of building once again. The 2nd biggest hurdle I have had was a lack of opportunity for shop spaces to build. I now have a viable workspace and full use of my hands once again to build. The problem is that, o…

Hi Peter and buona fortuna on your re-start. I would look into a thickness sander, drill press and small bandsaw. And dust collection! A good router that you can also mount on a router table. A laminat…

Sad Old '71 Hagstrom Swede

Greetings Wise Elders and fellow seekers of the Looth Group! I hope you're all keeping well. I humbly beseech thee for thine sage wisdom and experience. I purchased a 1971 Hagstrom Swede. This guitar was basically put in a case and then forgotten about for a few decades. I felt sorry for the old man and have taken it in as a stray / project. I would like to get it playing again. There are many scars on this guitar, I have looked for as…

74 Les Paul Broken Headstock

Guitar fell straight down on the headstock when it was hanging up at the refinishers. Shit really does happen! Grain is pretty much shattered around the adjustment nut. Thinking I’ll replace the entire broken area with a completely new piece of mahogany. Scarf it in between the volute and 3rd fret. Probably even a 3 piece lamination to mimic the neck. This one was not the clients fault so the expectations for looking close to original a…

Is an online course for guitar repair a good way to go?

Hi all. I've just joined the group....I'm pretty certain what I'm asking here has already been covered somewhere but not really sure at the moment how to search chat topics. If so, and it's easier to just point me to an older chat...please do so! I'm in my 50s, been playing guitar for as long as I can remember. I'm a trained wood-worker (amongst other things) and am looking to start a new journey into guitar repairs. At my age I can't a…

GlueBoost vs Nitro drop fill

*Photo added* Ding repair on spruce top, 2015 Collings 0002HE #23701. What are y’all reaching for when repairing dents in nitro? GlueBoost fill & finish or drop filling with nitrocellulose? This is a well-used guitar; not pristine and the owner has reasonable expectations that the repair will not be “like it never happened” Bonus question: If there is bare wood, should I seal it with shellac to preserve the color before proceeding to fil…

The coating on that 000 is a mixture of a UV poly base and nitro top coats. It seems that many of the deeper spots could benefit from steam applications. I use a paper towel, folded into four layers a…

70's Tele Neck w/ truss rod issues and a bulge behind first fret

I've got a client with a '72 Tele. It needs a re-fret, but the truss rod isn't functioning. In fact it's backed out of the channel significantly, and there's a bulge in the neck underneath the first fret which suggests to me there's something going on with the truss rod anchor. The puzzling thing is the wood in the neck has bulged, but the skunk stripe and the finish don't appear to be disturbed at all. I'm thinking I'll probably hav…

Epoxy Pore Fill question

When using epoxy (either silvertip or epoxy), I try to sand back the epoxy on the surface and only leave it in the pores. I'll start the process with sanding to 320g or so then using an air compressor to blow out the pores. The challenge that I run into is opening new pores in the process. I use a block of wood and long strokes in an attempt to avoid uneven sanding. Ultimately I'll get a good pore fill but I tend to apply several coats…

Are you having a hard time seeing when you have sanded just down to the wood ? If so, you might try a quick naphtha wipe. It should show off where the surface is still covered with epoxy. Due to the f…

Thoughts on Restauration Roger Archtop

Hey everybody, I should restore this Roger Rossmeissl Archtop. There is a lot of work to do. The owner is aware of the possibly-much-more-work-than-value situation. I am still thinking about how to aproach it, I want to start working on the guitar in August. It seems that there is not much warping in the top, few wood is lost. I do not know what happened to the guitar, but sometimes I hear a voice coming out the corner of my workshop mumb…

Neck block for adjustable neck -thoughts on design

I've built a number of classical guitars with an adjustable neck and they seem to gather quite a bit of interest, so i'm currently in the process of looking to refine the design and build. It's quite a simple construction where the neck is held together by string tension and hangs on a pivot. I developed a 3d printed "socket" which acts as the interface between the body and the guitar and allows for some fine tuning of the alignment of t…

PBass has been stripped of it finish… looking for expertise, friends!

Hi friends, I just stumbled upon a 1966 P-Bass, nearly completely original. The owner bought it in 1971 and it had already been stripped of its original finish. That was a thing back then. You can guess that 55 years of gigging had the wood absorb much of the owner’s DNA and sweat. Maybe a few beers as well. Surface was quite tacky as you can expect. I cleaned it with naphta and StewMac’c brand-new cleaner (quite a great product I'd say…

Cheap-ish Brace Wood Source

https://www.aircraftspruce.com/catalog/wppages/bargainbag_spruce.php The air craft industry uses 1/4 sawn sitka and this is a box of their "Scrap wood" that is a good value to have on hand, (usually like 36 in long and various width) imo if anyone is in need. It's an odd ball source, but just spreading info. Be well.

Spanish Heel failure

Hi all, I got a Do Santos DSMSCC RC in shop, the Spanish heel has failed , or rather collapsed into the soundboard, splitting it on both sides along the grain, a broken brace just under the fingerboard extension , cracks on both sides on the top/side bindings, I measured wood humidity on the fingerboard 9% and inside the (very inaccessible) body 11% The normal procedure would be to re-humidify before jacking or clamping back into place ,…

Local Thrift Shop Find: Gibson Ivory Top A3 Mandolin

A customer brought in a Gibson ivory top A3 mandolin. It's in good shape and has all the parts. He found it at the local thrift store here in Bishop. He wants it mechanically sound. Here are the problems: 1) Everything that comes into the shop has a shrinkage component and the effects of course very from instrument to instrument. This instrument is no exception and the results of that shrinkage, in this case, are severe. The top, ba…

Drum Sanding Tops and Backs - When and which sander?

So it seems that a drum sander would be very handy for many parts of a "build from scratch". There are a few out there that cost under $3000.00 that can handle wood up to 4" thick and are wide enough to sand a back or top after the halves have been joined.

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…
