Sky Watcher 10" Dob

I recently purchased a Sky Watcher Classic 250p. While I was machining a collimating cap, I decided to machine some new bearings for the alt movement out of Delrin. I wasn't sure if it would make any difference but it absolutely has, it's way smoother/less sticky. A very worthwhile upgrade for anyone who has access to a lathe and some Delrin.
