I retired at the beginning of this year, and based on rudy's poplar "banjo building 101" thread, produced this plan:

Today, I can post the finished product.

The fretboard is an enlarged slide rule, the drum is a Smith Chart, and the peg head is an electronic looking control panel.  The strap is meant to evoke the old punched paper tape memory storage that was popular in the 70's and 80's.

The cursor is a wide Paige capo that resides in the "zero-fret" space.  It can go all the way to fret 17, thanks to the tunneled 5th.  There is also a "minus one" fret beyond the zero in case I want to play in G-flat with the capo off. (Not really, it was just as easy to put it in as not, so there it is.)  The slide rule works, in that it can do squares, square roots, and reciprocals, but since the slipsitck doesn't slip, that's about all.  What else would I need?

Like most of my projects, not as good as I hoped, but much better than I feared.  I'm not ashamed of it.  My goal was that it should be playable, and it is that.  In fact it intonates very nicely, but the tone is weird.  The drum seems to be in resonance with the open low D.  When I capo up above 4, it sounds quite pretty.

(The preview tool here seems to put the images wherever it wants to, but you should be able to tell which is which!)

I really do like the look of the fretboard. Overall. a unique imagination & humor. I assume you'll be playing mathematic music.

Wow! Incredible. I have to ask, what did you do before retirement?

Awesome concept and execution.

So Garry,
What kind of engineer were you?

Very cool!

One of my muti-instrumentalist friends and former bandmate teaches advanced math at college level.
He says music is just mathematics at play.

I should send him your pictures!

Thanks for the kind notices. I was wondering if it would get Mike's attention. As to the questions about my past: the Model Number GITBEE-84H testifies to my degree - Georgia Institute of Technology (Georgia Tech to football fans), Bach of Electrical Engineering, year 1984, (with - ahem, modestly - Honors). If someone had told me 40 years ago that this is what it would come to, I would have thought they were crazy. Who's crazy now, huh!? (Oh, it's me.)

Very cool design (I'm an EE since 1982). Be careful taking it to the airport; you might be detained for carrying Weapons of Math Instruction...

Love it! If you ever get around to it, post a sound clip or two!

Now that is how to personalize a generic plan !
Great concept and cool looking result.
Congrats on completing it.
