Yeah. I didn't say it was easy! (No I haven't, but a long ago friend did, mainly to prove a point.) Actually, with a collet chuck and the correct tool you could do a bunch of rims in a lathe lickety split.

Sorry, being the owner of a lathe tends to shade my opinion of what's easily do-able when it comes to stuff like this.
