No I stabilized quite a few blanks, not dyed, so was no need to use the small tubes. When I did use them, I just cut some steel bars about 2 inches long and that was enough to hold the blanks down.Fantastic pen. I like the blank, and I really like the aluminum dividers with the ebony end caps.
Was the blank one that you used the smaller tubes within the vacuum chamber to stabilize? If so, I have been meaning to ask you: How did you hold the blanks down to keep them immersed in the resin? With my vacuum chamber from Turntex, I have a plate that holds down all the blanks in the chamber, but I am not sure how to hold down blanks in the smaller tubes. I am sure I could figure out something, but if you had success, I would appreciate your info. Thanks.
