Ron, years ago I bought a 20" ID sonotube from Intermountain Concrete Specialties in SLC. I used it as a mold to layup a 20" OD fiberglass tube, stripping off the cardboard when the fiberglass was cured. ICS probably has a tube that you can adapt to your needs.

Hey Group,
I have another ATM project going that has taken a turn in another direction (for the better). So I am in need of a Meades' sonotube for their 16 inch or Coulters' tube for the 17 1/2 inch. Anyone out there gut one of those for the optics and still have the tube, or know someone who has? Let me know.
Thanx, Ron _______________________________________________ Utah-Astronomy mailing list Utah-Astronomy@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Visit the Photo Gallery: http://www.slas.us/gallery2/main.php
