Got a question this time. Building a screen roll-up - motor at one end, support bearing at the other and 20' of unsupported something between.
I've tried large carpet tubes and got the middle joint of two 10' pieces to be straight enough, but it still droops too much. Also got a couple pieces of PVC pipe and it surprisingly droops more.
Thinking of somehow two wood I beams at right angles to each other, but not sure about how to do that.
We'll be just rolling up 15' of muslin, so it's not particularly heavy when all is said and done.
Thoughts and suggestions welcome.
