Possible uses I have thought of:
Rollers for a conveyor system.
Wind chimes.
Tent stakes.

Anything?

My uses include:

tomato stakes
flea-market tarp frame
cheater bars

I understand electricians use them somehow.

I've got a pile of 7/8 conduit. maybe 500 ten footers. And i need to make
tomtato stakes for 150 plants. I checked growers out in FL this winter. They
use rebar with the advantage being the tying twine you run down the row
doesn't slip - just loop and pull tight. Here I'm thinking buy rebar. How do
you use conduit for tomato plants? Specifially, how do you tie to this slick
stuff?
