Re: Trellis construction

I skip the threading of the conduit (which is very easy to cut with a
hacksaw,BTW) by using right angle conduit connectors, they slide over the
end and are held tight by screws included in the angled piece. Very easy to
assemble and disassemble using these. To make mine more stable I do attach
my trellises to the wooden bed frame by sliding them through U brackets or
where there aren't raised beds by bolting or cable tying  them to something
sturdy. Otherwise they lean in my moist clay soil. My trellises can be seen
