I use a PVC pipe cap one size smaller backwards inside the base of my
secondary. You will have to sand it or turn it to fit. I drill a hole with a
hole saw small enough to tap threads for a plastic pipe nippel in the center
of the cap and thread it. I cut a hole in my TC base to slip a nippel
through. after assembly I cut the nipple off below my base and glue a
plastic cap flush on the cut end. When ever I take it down I just unscrew
the nipple and it is ready to transport. Screw the nipple tight at assembly
and nothing falls,all ready to fire up.
