Paul:

Well done.... I have a fly studio that I use but I think I might just take your idea and use most of it. I also use mirrors but I use inspection mirrors that are attached to my base. I was kicking arount the idea of a light tent, but like the tube much better. Where did you find the tube? I understand the sanding, What diameter was the tube? I must have missed it in the article.
Great article, I agree it should become one of the FAOL articles.
