I've got a stripped spot on my bridgeport powerfeed. Its a plastic gear
about 3.58" O.D. Not a standard tooth form, some sort of inline worm gear.
See these dropbox pics:

Any chance of purchasing this gear? Or is the powerfeed "maintenance free",
buy another when it breaks. If I had a manual for this, I lost it. My
bridgeport gets nearly 0 use, but I HATE running anything without powerfeed.
