Justin,

The Model 9J uses a 20" PVC form and the 10J uses a 24" fiberglass form.

Warning! Non-scientific anecdotal information follows: I don't notice
any performance difference between the two materials (no flames from the
double-blind scientist gallery please).

Make sure you dry and seal the PVC (voice of experience here - no
science flames please) and you'll be just fine. I use Spray-On brand red
insulator.

Hello,

Has anyone tried to make a secondary out of fibreglass (woven cloth
type)?

I had planned to seal the PVC tube after drying.  Is it the moisture it
absorbs that makes PVC lossy or just the material itself.





Regards,


Justin.
