Our team is looking at putting a cylinder on the end of a chain driven piece of 1/2 hex stock. That way we could position it at any angle.

What would be the easiest way to accomplish fixing a cylinder to a hex shaft. We have come up with 2 ideas.

1. Broach the bottom mounting hole.
2. Drill out the end mounting hole and weld in Competition robot parts roller end cap.

We do not have access to a welder or an arbor press/broach so neither of these are too easy. Welding is slightly easier as there is an auto repair shop across the street that can do it but they will most likely charge for it.

Are there any good strong cots solutions for this considering the cylinder is 36" long?

Thanks.
