Added collars to hold the z-axis lead screws in proper alignment. Used hot glue for now.

I was able to find six of these sweet sprockets for dirt cheap at none-other than AX-MAN. I cant believe how lucky I am to have an AX-MAN just a couple miles down the road from my house.

I was able to get the y-axis linked up with my fancy new, very hard to find, ANSI 25 roller chain. Made a nice chain stabilizer out of the thick strip of plastic from some broken Sony headphones. Lesson learned... Its nice to buy locally but next time Ill just order the roller chain online from smallparts.com and save about 50% after shipping :-(
