On a different topic.  I've now been at my new job like a month now.  I'm a production engineer at a place that manufactures large gears, couplings, rope drums, gear boxes, track wheels and things of that nature.  Most of which are used in steel mills.  The track wheels are usually used on overhead cranes.  Some of the gears here are huge!  There's one in the shop that is about 12' Dia x about 2' wide.  I'll get a few pictures and post them in here.
