IRI - Looking to borrow a piston

[AlexD744]

Hello!

Our team, 744, has designed a pneumatic stinger for our robot for IRI. The piston we originally tested with was a little bit thicker than the one we have on the robot now, because the original piston was found to have a leak. The piston we have on the robot now works, but it is not as good. Therefore, I was wondering if any team would be willing to lend us a piston similar to the original.

I'm not sure how these are technically measure, but the tube length is 27 inches. The tube diameter is 1.25 inches (a little thicker is ok). And the shaft length is 24.5 inches. If the tube is slightly shorter or slightly thicker that is ok too.

Or, if someone would be willing to show me to a site where we could find a cheap piston like this. I had checked bimba, but the sizing was very confusing to me, any help with that would be greatly appreciated as well. We are on a really tight budget for this trip and the plan did not include very much robot modification.

Thank You!
