My team is trying to design a t-shirt cannon robot, to build later this year, if and when we are safely allowed to do so. I have been reading a lot of the other posts on here, and on the internet, as well as searching home depot, and I cannot find where to get a piping that is both large enough to make a barrel (2 1/2" I.D.) and that is pressure rated high enough to be used.
If anyone has any suggestions with stores/websites or parts that meet my needs help would be greatly appreciated.
Thanks in advance!
