Cutting the tube for the rear wheel rim!

And voilá: I tried the contraption I made with the follower on the tube for the small (rear) wheel. It went great! Everything worked out like predicted and I could make a clean cut on the tube to separate the rim from the upper part.

Finished rear wheel rim (needs some deburring). I asked the mechanic - who rolled the tubes for me - to make sure the welding seam of the tubes would be on the outside so it would be cut off. As you can see, the seem is on the inside... :-(
