This is more follow-up on the broken Vanguard gears topic:
http://forums.x10.com/index.php?topic=11187.0http://forums.x10.com/index.php?topic=11186.0The place I originally recommended for replacement gears has been sold out of that particular gear for a couple years now. I finally got around to fixing the rest of my cameras and thought I'd share what I had to do to make it work:
I ordered here:

Both this gear, and the one I previously recommended are too tall. I used a Dremel to cut the extension off the gear while holding it tight with a pair of pliers. Now, there was no way to secure the gear onto the Vanguard camera motor axle(s). The 3/16 hole that was drilled will still be too small (barely). Wiggle the drill around just VERY slightly after drilling the hole, and that will make it just very slightly larger. Do that until you can get it to slide onto the camera motor axle. I laid a square patch of plumber's tape (1cm x 1cm square) over the gear hole just before pushing it onto the axle. That would cause the tape to push up onto the axle and between the axle and gear interior while the gear slid onto the axle. Usually that would make ithe gear snug enough to not spin on the axle, but sometimes I needed two squares of tape if I had drilled the hole too large when wiggling the drill around.
Finally, the gear needs to pushed down far enough onto the axle so it isn't raised any more than the original gear was, when repairing the left/right rotation gear on the camera, else when you put the camera back together, it will rub on the bottom plate of the camera bottom and that's enough friction to keep it from rotating from just the force of the motor. So get the gear down and flush.
I was able to repair most of my cameras. A few have mysteriously stopped responding to the remote, and one, the up/down motor axle broke from the interior motor it was attached to, when I was pushing the gear on, so be careful not to use too much force.
