Hi Clay, I never thought much about bridge design, other than wondering about a formula for deciding how wide, or maybe why or why not to use a full contact bridge. Height is a new thing for me. I guess the higher the bridge the more force gets transmitted to the soundboard. A double bass certainly ...

Hi Jim and Clay, I built a CNC machine (MPCNC) and for my first project I thought I'd use it to make experimental fingerboards. Fingers crossed, still learning. Thanks for the pictures. It looks like a 3/4 size donor guitar and 5 courses of strings would make a pretty cool instrument tuned like an o...

Thanks Clay. My copy of the book has not arrived yet and I was eager to get the numbers. Thanks also for updating the thread. I would guess (and I suppose I could experiment) that the same ratios would work to scale up and down both the scale length and also to add a fifth course of strings. I just ...

Right, the adjustable is a temporary jig to capture the length for the four string pairs.

Thank you for your measurements Jim. Those numbers look sensible. Do you recall your reasoning for choosing that size? Regular mando bridges are compensated and the strings are more or less standardized. The strings for an octave would be very different. Folks often mix gauges, even mixing wound and...

Hi Peter. I may resort to measuring from a photograph or making a visit to a very expensive music store nearby with a plastic ruler hidden in my coat pocket. I'd rather someone else measure something they have in hand to save me the potential embarrassment. I will also measure off a paper plan. I fo...

I wonder if anyone can measure their octave mandolin fingerboard width both the nut and 12th fret (or 20th fret)? I'm trying to get a feel for both the width and taper (the bridge-end is wider than the nut end) that folks use for octave mandolins. All the luthier web sites I looked at do not give an...
