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…

Andrew, I'd like to talk to you about this question. Could we connect on a zoom call ?

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…
