If I am not mistaken, someone was mentioning, maybe last year, about adding 'rubber bands' to a 111a arm? Does anyone remember? Has anyone heard of or know where to get such elastic? I am about to do some work with a Panavised HD camera with a ridiculous lense on it and I am worried about hitting bottom on my arm. More than 31/2' long!!
thanks in advance.

Hi Peter

Sounds like it could be a nightmare job - all I will like to add is be carefull.

If it is too heavy for your arm, then you could be in for problems - is your vest also strong enough? is your gimbal also strong enough? and most importantly are You strong enough to carry this load for a full day + overtime? - all it takes is to get tired and slip.

in my many years, looking back there are a hand full of jobs I should had said "No" to! - and I still have the scars.
All I would say is you are the most important part of a steadicam package - it is easy to get a new sled or new arm - not so easy to get a new knee or back.

You really need to ask your self is this really worth potentially hurting yourself over?
I wish someone had said this to me 15 years ago - before I ran up a sand dune with a BL4s in Saudia on a Mk3a with all the toys!

Please take care - belive me it is not worth hurting your self for!

All the best and to coin a phrase "Fly safe"

Take care

Hi all

I worked on the TV series Ponderosa (prequil series to Bonanza), with the Panavised Sony HD Cameras, straight from Star Wars Ep 2.

The camera worked great with the Miranda, but the Focus Puller had the Panatape, Short Zoom, 2 focus motors and the cable loom from hell (including vision, CCU and sound cables for recording sound to camera and Dat, so we had a boom op following also) running back to the TD's truck. I had the gimble at the highest possible position, the post at full stick and i still had to add weight to be base of my then Pro 1 to get a static balance.

To add insult to injury, we were in the worst possible conditions as far as working, rain, hail, mud, snow and sun all in the one day, as well as days of each.

The arm worked fine until the final shot of the day when it said "I've had ENOUGH" and the top 2 trunions on my 3a arm literally snapped in half while i was taking the sled off the stand. A quick dash to the grip truck and several standard bolts through the top bones and I was back on set within 5mins to get the final shot.

Luckaly the director (who was also following and standing next to me) or myself was not hurt, but it just shows how easily it could happen. But at the end of the day, the director was happy with the shots.

I have now upgraded to a Steadyrig Silver Springs Arm and can now fly any camera (including the above) with ease.

In my 15 years of Steadicam Operating, this was the heaviest camera setup i have ever flown.

Will attach photos when i can find it.

This is about what I had during my shooting in Cambodia and Thailand last year:
Panavised CineAlta, with a big Everz downconverter behind and a Li-Ion battery, 6-27 zoom, 3 Preston motors, mattebox. Apart from 2 stiff HD-SDI cables no others.
Did have to work with the HD-LCD that was not really made for daylight viewing.

The IIIa arm I had could just handle that, as you said all cranked up.
With the Progear I have now, no problem, I just need new springs in my legs!

I only survived this shoot thanks to the delivery of the DSD-harnass!!!

Hi there

I've got a modified EFP (IIIa) arm that allows me to put elastic down the sides for extra capacity. It works 'OK' - a little bouncy like you might expect but it stops having to hold the whole rig up with one hand whilst trying to look normal. I've flown HD with all the toys, GII's with zooms/1000 mags etc on this set up and got the shot rather than having to say no. The problem is the stresses it puts on everything else.

GII with a zoom and 1000 ft. mag? All I can say is WOW! I sure wouldn't do it. I'm sure my master arm would fly it comfortably since I had plenty left to go when I've flown GII's in the past, but a 1000 ft mag and a zoom?! Come on! You know, there are times when, "Sorry, that can't be done" is an acceptable response. I've been asked to do stuff like that in the past and said "no" in a respectable way, and no one had a problem with it. You'll only make things harder on yourself and your gear when you say yes to things like this. And really, what's the point anyway?
