Curious to know, I have always thought that in order to bend purflings into a ring you didn’t have to glue both the inner and outer veneers otherwise you create something called a torsion box. But it looks like I was wrong because you are doing it 😊
Very nice work! I keep hearing myself saying “use a push stick”. There are hobbyist table saws available but I’m guessing they won’t last as long as yours and may not be as accurate.
🙏🙏🙏thank you so much David for being so generous with your time and knowledge, not only on this video but also on your website and contributions to guitar forums; i've learned a lot from you, and certainly would try this purfling on my next guitars!! 🙏🙏🙏
That's called a loose tenon - the tenon is loose rather than being part of one of the pieces and the mortise (hole) being the other. I guess that makes it a double mortice but technically furniture makers would use that name for something that has 2 holes with a piece that has 2 tenons to fit into it, so loose tenon it is.
La proyección correcta del mango es 7mm el diapasón con una caída de 1mm en los graves hacia el final ,proyectando la regla sobre el diapason sin trastes deve ser 4mm en el lugar del puente , 8mm el puente , altura total con la cajuela 11mm graves y 10mm agudos .
Maybe for your guitars, but not for mine. I use a 0.400" (10mm) saddle string height and a 0.110" first string action. I do not use a fretless fretboard. My surrogate fretboard blank includes my fret height. The method I demo gives me perfect 10mm saddle string height every time for my last 400 guitars that I have used this method on.
@@schrammguitars en su web apentricie on line explicaba dejar la proyección sobre la tapa en 6mm ,y 12 mm de altura total , el 90% de los guitarristas usa 4mm a 3.5mm de altura en el traste 12 con esa proyección de 6 mm tiene wue elevar la cajuela más de 12 mm y el toque que produce es efectivo según la regla de young y las cuerdas se ponen muy duras.
Couldn’t you make a second hole in the fingerboard and another Allen screw for a set screw that could be fastened from the top? You would need an inset nut in your neck block.
Hi David, thanks for another interesting insight into your guitar making. Do you use this method because it gives mor control over the traditional Spanish heel approach. Additionally, why not use your adjustable neck design with all the advantages it provides?
I use this method on Spanish style when I set the neck angle with the back. I show it in my Hauser style build CDRom and Rodriguez style build CDRom I build in many styles.
Dear David, thank you for sharing. I congratulate you for your wonderful work. I have been making my double tops since 2005 and routing the chanel used a straight cut router bits. I love the curved shape on the channel edges of the nomex. What model of drill bit are you using? It looks like a bowl drill bit. I wanted to ask you about the drill bit. Thanks in advance
I learned how to make them from Greg Byers at a class at the American School of Lutherie 24 years ago. Greg has an article in American Lutherie. I will make a video on how I make them since I've used them all up!
David, I watch a lot of guitar building videos and have not seen anybody else using Gorilla glue. Most folks use PVA, hide or epoxy adhesives. Could you please explain the logic behind your choice?
I've never seen a double top with Nomex built with PVA or hide glue. That makes no sense. Who builds Nomex core double tops with those. I'd love to see their videos. Matthias Dammann told me to use Gorilla glue many years ago. Gernot Wagner uses it, Greg Byers used it, I've been using it for 20+ years. I don't use it for everything, only where it's properties excell. It doesn't add moisture and cause wood to expand. It is heat resistant for bending parts that you do not want to move when heated etc.. I use it for Fingerboards, Neck joints, laminations, rosettes, purflings, oily woods like cocbolo,...
Is there a video planned to do the headstock end as im totally confused by so many video variations on you tube. There must be the official way thats able to be clearly shown?
also cedar? I really want to know the difference between a solid cedar top guitar and a cedar-cedar-cedar double top guitar (the core pattern depends on the maker’s choice).
That was an expensive rosette mold! 😄 I had a similar experience while making an OM-18 style rosette with black dyed veneers and hot hide glue, the black color leaked into the spruce. I made another one using UHU Hart glue (it’s like a german Duco Cement) and the result is perfect.
Hello actually im using intern 38C guitar and my bridge is broken so i remove the bridge and I find everywhere for same bridge but I couldn't find it, so now i ordered pin bridge but there is no hole for pin in the guitar tell me what do i do now😭😭😭 please reply
@@snowww120 That model of guitar is considered a toy guitar. Very poor quality. You will continue to have problems with it. It is also a steel string and not nylon string classical.
I've been thinking of something similar for ingesting epoxy into the plywood I'm installing as the transom of my boat. Usually vacuum-bagging is used with peel-ply coating the surface but I'm thinking floating the plywood on tacks in a hard-space vacuum filled with epoxy will do a better job. I've seen your idea used in sheet-metal bending operations. You might want to put that loud pump somewhere in the next county.
Hi David, I’m enjoying your you tube presence that I recently discovered, and wanted to thank you for your on-line apprentice course that got me started building guitars. I had all the books at the time, and while helpful, none let me really understand the total process. Your course did, and my very first guitar using basic tools was a success that my wife still treasures. As a hobby, I’ve now built ten, and although I’ve added other learning resources, your course launched me on a very rewarding journey. Thank you for sharing!
