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...

Re: 12 String design thoughts

Jim, that sounds like a great future project. A good example of that style guitar is the Leo Kottke signature model that Taylor used to make back in the 1990s (but has now been discontinued for many years). Forgive me if you already know it - but if you don't it could give you some ideas to start yo...

Re: 8 String bocote falcate braced nylon string crossover guitar

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...

Hello, and welcome to ANZLF. Those are a couple of nice instruments that you ahve shown us. Very well put together. The redwood and blackwood combo looks sweet.

Hi Pete I love the attitude shown in this guitar - just get the job done. And it sounds great!.

It is great to see one of your instruments here Craig. That is a monster. Looks great. Your own design, or off a plan? What things do you need to alter making a bass, compared to a six string? Obviously the scale length - but do you brace it differently, or anything else different in the constructio...

Re: Huon pine in a laminated neck?

I haven’t replied so far because I have not used Huon pine in this way. But now you have me thinking. When looking at the specs it does indeed, seem to be a good contender for guitar neck building. It has very similar characteristics to mahogany, which most would consider to be the gold standard. On...
