Shaking GOBOs

How do you keep tightly focused GOBOs from shaking during a loud concert? They're in 19* S4 ERSs

Where in relation to the speakers are the lights mounted?

Is the whole fixture shaking or just the gobo in it?

If the building's structure is experiencing these vibrations, I don't think there is much you can do aside from relocating the lights and hoping for the best.

Muffler Tape. unless the gobo holder ismoving as well, then maybe taping the holder might work as well...

Well, all I can tell is that the end result is the pattern shaking. I can't SEE the instrument vibrating, but that doesn't mean it isn't. My guess is that it is the entire instrument and that the entire room is vibrating that much.

I had one of my vendors suggested using a yoke with 2 c-clamps so that the vibration is distributed more evenly, any thoughts?

also, the instruments are on the very last lighting position furthest away from the speaker array.

Depending on the throw distance, it could be the entire instrument. remember that a tiny, possibly unnoticeable vibration on the light can turn into something quite large 100' away.

If the entire venue is shaking (which happens at concerts at times), try mounting the ERS to the pipe with these anti-vibration devices:

How do you safety that?

I think I am going to wander upstairs and see if Keith can give me a demo on that....

Well, if one has a few slinkys in their roadcase surely they have a pack of Wrigleys gum too!

A Source Four connected to an Apollo Right Arm with one of those anti-vibration devices would increase the range of movement for the fixture substantially! (Do you think that would be covered under the warranty, Keith?)

Only if the Slinky (with the lighting fixture) weighed less than 40 lbs.

Guess I can't use my cast iron slinky then. Dang. (Now I kinda wish I actually had a Right Arm at school to use...)

All it takes is a request, and you'll have a demo at your doorstep Chris-

 

[seanandkate]

Is there any way you can put the pattern in an instrument that is closer? The longer the throw, the more any vibration is going to be amplified. It's not half as sexy as the slinky solution, but . . .

That's #2 on the list of things that would be cool for my school's TD to get a demo for, (or purchase) right before the Element, and right after the MXR.

Personally, I'd love to see another Apollo product in our space. The Smart Move we have works wonders, and your gel seems to last longer than anyone else's in our Colortran ovens.

Actually, would something like a Smart Move keep a gobo more stable?
