I recently bought a used Archer 2. As I was practicing whip pans i notice that my post would slide ever so slightly after I'd grip it to a stop. Is there a problem with my gimbal? I was wondering if that was normal or something I should look into fixing.

Victor,

I have not owned a Tiffen gimbal since the 3a (which was actualy CP then....)  but I know the quick release clamp on all their tooless gimbals can be adjusted to prevent this very easily by you. Hopefully someone will chime in with details.

Alec is right; it's easy to adjust.

There are two small hex head screws in the lever mechanism that can be adjusted to tighten the grip.

A very small amount of adjustment has a very large effect on the tightness of the clamp, so go very slowly.

I would tighten the screws by first releasing the clamp, and then turn the screws in 1/8th of a turn or less - the smaller increment, the better. Tighten both screws equally.

If the lever won't go over centers and lock (i.e., close with a snap), do not force it - you have gone too far and need to back off the screws.

This can become a problem on any rig from any manufacturer. Just don't over tighten because you don't want a snapped collar.

Weirdly I actually started playing with loosening my gimble off for whip pans to get a nicer lock-off at the end.

The time you want to make sure its real tight is on vehicle mounts.

Hi Stefan,

had the same problem. It´s because you need US-style, "inch-based" tools. I bought a toolset from Bosch (http://www.amazon.de/dp/B000NDGQD4' class='bbc_url' title='External link' rel='nofollow external'>Link to Amazon). There´s an allen key labled with "T20" included which is matches the gimbal clamp screw.

A similar trick when using Antlers is to loosen the clamp so the Antlers don't rotate when you do a whip pan, then they "re-lock" at the end of the pan.

@Wolfgang
I already got me a set of keys in inch size, but none fitted. So I'd prefer a single one instead of another box :)
Do you have the exact size?? Must be something between 1/8 & 5/32.
Maybe 9/64, 17/128, 19/128??

thanks

Jerry, you are insane.

Don't you know that Eric has an equation to prove that this cannot happen unless in a vacuum?!

Sorry, donĀ“t have the exact size. But I think this one should work...

Ron- Really! Alters have flux capacitors at both ends, otherwise this would not work at all. (full disclosure...)

Hey Jerry, do you recommend the new cold fusion power cubes to power antlers as they need 1.21 gigawatts to heat up the flux capacitor :D
