baronep1,
Do you have a lathe with a drill attachment and someone that knows how to use it?

Do you have a drill press?

We would have had difficulty with drilling a proper hole or press fitting the aluminum round bar without both machines and some expertise...

If no local expertise, find a local team or machine shop that will lend you a hand to make the parts and assemble them to your specifications.

There are many teams that try to get by with hacksaws, vises and power drills and don't know what a gear-puller or a press fit is.

To me, it's not very sporting to get you to try to imagine what the right machine shop tool is if you have not been trained in a motor machine shop nor have access to one.

Now it might be that you have a motor expert mentor and machine shop and you asked here before asking the local team mentors: but I find that unlikely.

Good luck.

(I would not advise you to try to make the hole in the cylinder or try to attach it to the motor without the proper tools).
