Re: Tiger Myrtle and Ancient Spruce Concert

Hey Allen - what is your source for the paua shell that you are using for those fretboard inlays? They are very beautiful. Looks like a stained glass window. Of course, the rest of the uke is fabulous as well.

Re: Falcate braced Parlour

Nice job Francis. It is a great idea to do the pre-build design work on photoshop. I have never tried anything like that before. I make it up as I go along, without knowing exactly what it is going to look like. That is fine when I am building for myself, but when it is for a customer it must be gre...

Looks great. Elegant, but also looks very powerful. It is great that you have mastered the build techniques now, so that you can focus on the challenges of the unique new aspects of each build. Love your work!

Re: Cutting notches in braces

A couple of years ago I was lucky enough to get a Bridge City jointmaker second hand, for a pretty good price (a single wing - the "cheap" model). It is the Rolls Royce for doing precision cuts. Check out the video.

Re: 12 strings dread/cutaway in Myrtle/Kauri

Designing the headstock for a twelve string is quite a challenge. You got pretty straight string paths for yours so it should work well, but I notice that the 11th & 12th tuners, and the 1st & 2nd tuners, are in reverse order. It works, but do you ever get confused which tuner is for which string? N...

Re: Shaping rasp

So, Jesse - are we helping you? More opinions than you can poke a sharp tool at. I also use the Stew-Mac dragon rasps, and the Microplane (large round), and often also a Veritas spokeshave. But many tools will get the job done for you. Cabinet scrapers are good for the final stages of smoothing. Nec...

Re: Need E4 string for 500 mm length.

Another thing you will probably find useful is Graham McDonald's universal string tension calculator. You can use it for all kinds of instruments of different scale lengths. For example, his preset values for a mandola will be pretty close to what you want. But you can set any custom values that you...

Re: Broken drill bit in tie block

I do love the look of that bridge. And 18-hole is a great design for tying the strings quickly and neatly, and so much neater than tying them around the tie-block. Your triplets of holes are a lot neater than my last effort at that. I am sure you will get there in the end.

Re: 12 String design thoughts

Maybe use a longer scale length, or even fan fret multi-scale to keep the string tension down on the lower strings. I'd definitely consider a fan fret....but if you haven't made one before be prepared for a few challenges :) But Martin has already made all of the mistakes, and documented them for u...

I love the design, love the bocote/lutz combination, but I especially love the really blonde colour of the neck timber. What is that? I matches so well with the spruce, contrasts nicely with the bocote. It is great that you are getting commissions for interesting and unusual designs. But it must be ...

Re: Reducing x-brace angle?

Great ideas for measuring this variable. I will definitely do this when the instrument is finished - to see if I stuffed it up! Might then need Steve's planned tutorial about how to increase the rotation (carve the bracing through the soundhole I am guessing?). Would deflection testing of the free p...

Reducing x-brace angle?

I am retopping a Martin OM style instrument. This is an Engelman spruce top and at 2.5mm it is still fairly stiff across the grain, compared with the last few spruce tops that I have worked with (which were sitka, lutz and adi). I am bracing it with sitka and I have just made up the main x-brace. My...
