Loose Volt encoder ring

Hi all,

I had to do a lo-mode shot the other day and after inverting the rig I hear a noise, I look down and see that the encoder ring has slipped off the gimbal. A relatively quick fix with some electrical tape to hold it in place. To be clear this wasn't the whole encoder ring assembly just the encoder ring. The rest of the assembly was still in place. Has this happened to anyone else? I couldn't detect any glue residue one either component, how are they mated together in the factory? Are they just a press fit? It was a hot day but could the encoder ring expand in the heat enough to simply slide off the collar? 

So, looking for the best suggestions of the best glue to make a more permanent fix. I thought that perhaps a few drops of nail polish may be a good way to go so if needed I can un-fix it with some acetone. 

Any suggestions or similar stories most welcome.

Thanks

Geoff Owen

Hi Lawrence,

Thanks for your comment. Yes you're correct,  it's supplied as one complete component from the factory that you fix in place with the double sided tape, but it seems that this assembly is made up of 2 components, one is the main body of the assembly and the other is the ring that has whatever technology in-bedded that the encoder/sensor reads. In my case the main body is still in place, the double sided tape has not let go, just the ring of smart material has slipped off the main body. I would expect that they aren't intended to come apart but in my case they have. Perhaps a call to Tiffen is the best bet here.

Regards

Have just spoken to Tiffen about this problem. They tell me that they've only heard about this happening a couple of times before. Apparently these rings are only glued in place if the fit isn't sufficiently tight when assembled. An easy fix with some adhesive. If you have this same problem it may not present itself until you go into low-mode. Maybe the temperature did cause some expansion of the encoder ring for it to become loose so cold weather operators may not encounter this issue.  So for all you Volt owners perhaps a quick check of your encoder ring may save you an embarrassing moment on set.

Sorry I misunderstood your problem. Glad to hear you got it sorted out. Clearly the Volt is not designed to sustain the forces present below the Equator.;-)
