Invetner 08 - Gears

I’ve been working with Inventor 08 for a couple of months and I’ve found on the Design Accelerator that whenever I try to make a gear it comes out with a gear a completely different size than I thought was going to come out. Is there any way to fix that? If not is there anywhere I can download pre-made gears to use of various sizes?

SDP-SI and Firstcadlibrary are both places I go to for gears often.

SDP-SI sometimes only has a few teeth modeled, but usually some cuts and rotates will get you a complete gear.

IGear from firstcadlibrary. You can edit some details to make it the gear you want. Here is a link:
