Hello. I can't remember the place I got the aluminum band from. It was an online metal piping place. I bought the "guts" from CUSA before they introduced the "click" in kit. The idea is somewhat stolen. My wife really wanted the same pepper grinder used by Giada (Italian chef on TV) and I couldn't find it anywhere (there are actually posts online about the un-availability of it). I decided to imitate it with my choice of wood and CA finish. If I was selling this I probably would not use CA again as it was somewhat of a nightmare to get it to look like my pens. As mentioned prior, Walnut can really soak it up and has a ton of small voids that need to fill. Maybe using a different wood would work well with CA. If you have any questions feel free to PM me.
Thanks for the encouraging and complimentary words.
Ryan
