Thanks guys! I'm proud of that one. It was a couple late nights, that's for sure. Jeff, please do feel free to post it wherever you like.
Kirk, the machine has a lot to do with the finish, but I do it just like a wood or acrylic pen. Start with a relatively coarse grit and sand against the machining marks and get progressively finer. I end up polishing them (and my rings too) with hard cotton buffs on a rotary tool to get the fine pits out and end up on my 8" polishing wheel to give the final blending run which removes any swirl marks from the buffs. I use a white waxy compound made for stainless steel.
Part of the cool part of the design was getting rid of all the threads. I was amazed when I got an El Grande pen that there were all those inserts with threads. I lost count after a while. I drew everything to scale, and was looking on ways on how to spice up an El Grande, and I saw that it was all pretty much defined for you. I was going to have to get radical in order to change things. It took a couple long nights of designing, and another couple nights of thinking through how to actually make the parts. I had to order a bunch of cobalt drills and I had to made a few fixtures in order to get started.
