Just a reminder that I still have some aluminum rings for sale. These rings are leftover from the development of the 300mm Dome run. Most people who have purchased these plan to use them with plastic domes or R5 domes. There are tons of uses for these things, so Daren wanted to get them out of his shop and into builders' hands!
All the info can be found at the Scratch and Dent Section of 300mmdome.com
