Ok, time to take another swipe at the Wiki. Before I do, I had
another possible addition to simplicity domes I wanted to put before
the group for collective input.
I've seen more than one reference to making lightweight domes for
garden greenhouses from black plastic pipe. This is the more flexible
stuff, often referred to as "black poly" (for polyethylene.) The
cheaper stuff is rated for 100 psi, and the more expensive version,
often rated for use with potable water, is rated at 160 psi, which
seems like it has a thicker wall. One can just cut the pipe, drill a
hole and bolt the strut ends together, much like the conduit dome.
Does anyone have any experience with this? I'd be curious to know if
you've run into any problems with this, or discovered any unexpected
assets.
Another question came up about dropping a piece of rebar in each strut
and filling with inexpensive redy-mix concrete (just add water). Does
this work, does it add any useful strength? I know it is sure going to
be heavy.
Any comments or insights welcome.
