    Extreme miscalibration

    I know about the steps for gimbal calibration: 1. Balance the unit in 1 position 2. Rotate 180 degrees 3. Adjust gimbal until the tilting is halfway gone 4. Rebalance unit 5. Repeat for 90 and 270 degrees. The problem lies at step 1. I just can't get it to stay in balance, because the center post starts spinning on its own and then the whole thing starts tilting. Is it smart to just guess the gimbal adjustment first, so that I can at least get it to stay in balance, allowing me to then precisely calibrate the gimbal?
  2. I recently bought a second hand (barely used) Glidecam HD 2000, after being disappointed by a cheaper 'fake' glidecam (this reminded me to always buy the quality stuff). The balancing seemed to be a lot harder than with the fake glidecam, even though it used the same kind of mechanism to achieve balance. When I finally got it (almost) balanced, I rotated the center post just a tiny bit, and the balance was off. When turning the center post 180 degrees, the glidecam is way off balance. Picture when in balance. Picture with the center post rotated 180 degrees. I looked up some information about this and it seems the gimbal calibration is off. So I managed to order a 1/16" allen wrench (those things are hard to find in a physical store in the Netherlands) to calibrate the gimbal (I already have the required torx wrench), and I started wondering. My gimbal is so extremely miscalibrated that I can't even get it to stay in balance because the center post start spinning on its own, and then the whole thing starts tilting. Is it a good idea to just guesstimate the required gimbal adjustment a bit, so that I can get it to stay in balance, and then proceed to precisely calibrating the gimbal? My drop time is 2.5-3 seconds. Regards, Sander
