making greenhouse frame supports like this

making greenhouse frame supports like this, by using a small press to crimp the pole ends. with a small bend and some metal screws they can get attached to the inside of the frame to ensure any sharp corners won't come into contact with the poly. a dozen or so like this and the frame will be very rigid. note if you're wondering about all the crazy poles strapped to the ceiling, they're all coming down once this process is done and the new woven poly goes on.
