Mandocello neck block

I am building an archtop mandocello (A style) and I'm trying to find out how to make the neck block. It would be more or less like an A style mandolin neck block, but obviously quite a lot bigger. More or less like the image attached. The blank should be aprox 10 x 8 x 12 cm. I'm trying to find a piece of hardwood big enough for this, would it be acceptable if I made some kind of laminated piece? And how should the grain direction be idea…

The traditional A style mandocello neckblocks were mahogany. There are some really good reasons for laminating them because there are forces on the block that make any single grain orientation a damne…

Incoherence between CAD and test-piece

Good morning everyone, I was taking some measurement on production necks with scarf-joint (13° headstock angle) to add some machining process with the cnc. I so recreated the standard neck blank feature (100mm wide and 20mm thick), then drawed the 13° angle. Everything correspond the to the real piace but two measurement: the startingcut behind the break angle is ''off'' by 20mm +/- as well as the cut on the bottom, still off by 20mm…

Is it possible that the angle of the scarf joint is different from the angle of the headstock on the real piece? Could be a manufacturing quirk

Stelling Banjo Tailpiece

Hi all! I was wondering if anyone knew how to source a Stelling tailpiece or knew of what would fit? I have a White Star model that came in with one that's broken. I tried their website and I just get errors and I understand Geoff Stelling retired a few years back. Images

@member Make sure to use MAP gas if you are doing silver solder. Propane won't get hot enough

Looking for Looth Feedback

Hey Everyone! I have been messing around with a program that Ian introduced me to called "FarPlay". It is similar to zoom but designed for playing music together. In prototyping it I have made some discoveries, particularly that you need a really solid internet connection. Wifi seems doable but causes the most problems. If enough people were interested I am imagining two different ways it could be fun for us. The first would be…

Wood-Body Resonator Guitar Construction – Materials & Suppliers?

Hi Everyone, I believe this may be my first post here, so just a quick introduction — I’m Andrew in Milwaukee, WI. I’ve been building a few years. My luthier eyes were opened first by Charles Fox in Portland which led me to the Gallop School. I recently retired from a tech career and I am now based in Milwaukee, WI focusing on acoustic builds. I’m currently exploring wood-body resonator guitars, and I’d love to learn more from t…

Mandocello top tap tuning

Hi all, I am building a mandocello, Gibson style but with f holes, currently working on the top. I got to a point where I carved it to about 5 mm in the center and about 3,3 around the edges. If has some flexibility but still feels quite stiff. I tap and listen but having experience only with flat top guitars I don't really know what I'm looking for in terms of tap tone and flexibility. I know there is no correct answer to this, but anyo…

One more update. I have been generating Chladni patterns for the top. I normally do this with the closed box, as most luthiers seem to think that on free plates it's not very useful, but I found this…

1917 Gibson U style Harp Guitar

I've had a customer come to me wanting to electrify the guitar without any modifications to it. No drilling, routing etc. I did convince him an end pin jack would be the only option, and he was ok with that. After a little thought I thought a K&K with a microphone (K&K Mini Pro) might work, using the transducers on the six string side and the microphone on the ten string side. I have no doubt the transducers would work fine. My concern…

Can't access truss rod

I bought a boutique guitar, used from Guitar Center. I really want to like this guitar. I just got it a couple of days ago. Looking forward to doing a setup. The neck is straight. I went to add some relief and found that the wood around the truss rod keeps the 4mm hex key from engaging. Any suggestions on how to hog out enough wood to get access? I was thinking of superglueing some 180 sand paper to a 4.5 mm hex key and sanding the…

If I really liked it (or it was a client's guitar) - I might go fearless with a drill bit on a low setting to remove some material for access.

Modular Clamp For Acoustic Guitar Repair

So, I made a modular clamp based on the split clamp idea. Started on a prototype about two months ago and finished it. What I was aiming for was a clamp that I could use on the BOTTOM of acoustic guitars as well as tops to clamp cracks, cleats, braces, patches etc. Especially a clamp that would access small openings like "F" holes, small sound holes etc. Essentially a way to get a clamp to areas not accessible to jacks, wedges etc.,…

Osmo oil finish

Hello. I am interested in the luthiers opinions about using Osmo oil as a finish on acoustic guitars? Advantages vs disadvantages. I am a new builder with small home workshop, mostly using hand tools to build my first acoustic guitar, an OM pre war style. Thank you all.

Strange Fender neck with some problems.

Hello fellow looths! I recently had a customer come in with a '71 Fender neck that is a fusion of the 60s and 70s style. It has a veneer fretboard, no skunkstripe, 4 screwholes, 70s style tuners, 70s headstock logo, and it seems like it has a poly finish on the back of the neck, and nitro (with cracking) on the front of the headstock. Can anyone tell me if this combination is possible or could it be fake? Another thing is, even without th…

Hello friends - I am a bass guitar builder who is considering building a neck-through Flying V-style guitar with a 25.5" scale length and a Floyd Rose tremolo bridge. I have not built any neck-through instruments and would appreciate any guidance on where to begin with respect to laying out the design, in particular, getting the neck angle right and the headstock angled properly. Any resources are welcomed and if someone has any interes…
