We're going to have to agree to disagree on that point then, because when we did it the tube expanded and was unusable.

or is there a way to improvise using maybe.. short bolts..washers..glue even?
after all its not for competition but for my school project hehe
so just as long as the concept will work its fine.
The barbs we used were from McMaster, and are brass. I cannot for the life of me remember the part # but I can find out for you.

Before we were using the barbs, to test the lift system we took #8's, cut the heads off and left about .5 inch, then pressed the ends of the tubes onto the remaining bit. We had pre-drilled the tubes about .70 inches away from where the #8 would be housed within the tube, and used small cable ties through the tubing to cinch it together.

It worked, but was really only a temporary solution in our eyes.
