Just follow the pattern they use. <<<<<
Still another example of richard not knowing
anything about what he is talking about.
First, the conduit is made of soft steel.
It would rust to nothing in a year or 2.
Second, you can buy pre-bent 90º bends because bending
a 90º bend isn't as easy as richard seems to think.
Half inch tubing would be too weak and you can't bend 3/4"
tubing into a close enough bend for a lawn chair.
Anyone trying richard's idea will end up with a bunch of
kinked tubing and a $25.00 bender that they can't sell.
