Jon, to make this pen (and I've tried once and the photo is in the photos area of the site under my name Parson) I printed out an enlarged color copy of the pen first. Then I started at the top of the base and worked my way back to the bottom end of the pen. I didn't know how to do closed-ended pens back then, so I just did my best. I also had never seen the pen in person so I had no idea just how stinking FAT the thing really was, so I used a Sedona kit and I should have used a Gentleman's kit or something with much much larger tubes.
Next you have to start cutting all the pieces. My friend helped me make a table saw sled on which we bolted an Incra Jig and a piece of wood with a couple of hinges on it that allow me to hold the material in place as it's being cut (to eliminate kickback or saw marks or uneven cutting).
BTW, I purchase uncut "slabs" of PR from exoticblanks.com which are the width of three pen blanks. They don't have them listed on their web site, so I just called them and placed an order over the phone. By having larger slabs of PR, you have far less waste and a larger chunk of material off of which to shave 1/16 inch slivers.
There is also extensive use of my sander and band saw for the 45 degree cuts.
Gisi is evidently laminating dyed veneers for all that multi color work... I've tried to use dymondwood and it cannot be made to look that way because it has a dark end and a bright end to it (very frustrating, btw). For the white parts he used plastic signage from Home Depot (the cheap ones that say, BAD DOG or Towing Enforced)... this stuff works well if you sand off all the screen printing and rough it up real good on both sides.
I thought the black he uses alongside the white was pick guard (for guitar faces) but one cannot procure it that thin, so I'm thinking it's black dyed veneered wood. He probably took a whole sheet of black veneer and glued it down to a full Home Depot sign so he'd have a bunch of it to work with. [If anyone reading this wants to PM me with the source for ultra thin BLACK and other colored plastic in 8.5x11 or larger sheets I sure would be appreciative!]
I'm gonna give this project another whirl over the summer months. I bet I can do get a lot closer now that I've made a bunch of pens and I'm thinking more like a segmenter now than ever before.
