I have several change gears on eBay (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=150423332041#ht_500wt_1182).  Here are the pics of each individual gear for sale.  I cleaned each gear and reapplied a thin coat of oil, so they are ready to go.

After several months of reading, waiting, and watching, I finally have my first metal lathe.  I found an Atlas 12×54 Series F (circa 1950) from a nice guy in NE Tennessee.  There’s quite a bit of reading to still be done, as well as parts to be ordered, before I turn anything, but it’s in working condition!  Now to resist the urge to spend the same amount on tooling…
