Gilles;

I thought I'd seen everything. . .

Guess they'd have to have exactly the same spring setting or they wouldn't work in harmony with each other?

How much did the rig weigh?

Did it work on a vest too?

First off , I have used the freestyle rig just like the rig that larry was carrying on the picture in the other thread. I haven't weighed it but it's 100lbs ish .
I'm not going to bother modifying my vest . The dozen or so shots on the vest isn't worth it. When i first put the beast on my 72 lb capacity 3a arm
the tall post bent and I got Walter Klassen to get me a solid case hardened 18in post . It bends but much less. The post became the focus of attaching two arms
on it and then getting a second pipe mounted garfield. The lower arm is set stiffer. The Klassen garfield is fully adjustable and I compressed the MK-V rig
by adding two hydron bats. I also have a racing seat that has pipe mounts and it works really well. Hopefully no one has to use the Alexa 3D rig again.

What an awesome set-up, well done thinking outside the box to come up with a heavy duty solution on the arm.
Just wondering though, how does the gimbal hold up with so much weight, do you know what the maximum load capacity is on it before the yoke mushrooms and dies a death??
Also I am really curious as to what the double-arm combo is attached to, looks like a cart possibly or a dolly but it's hard to tell from the picture, hopefully with the advent of the epics and the new Alexa M such insanely heavy set-ups will be a thing of the past, thankfully I haven't had the displeasure of 100lbs bearing down on my spine and hope I never have to lol.
Excuse all the questions and thanks in advance if you find the time to answer them, such a curious set-up and I have never seen anyone come up with anything like that before, kudos to you sir.

The dolly is a Fisher 10 .I also mount a racing seat with a mitchell base onto the dolly. I did a few shots on "The Thing" that way. with the Klassen garfield rig (check his web site) I have rigged 2 inch pipe off the side of the chair,and rig two arms off of it . The trick with a seat is to get a foot rest organized using pipe. I also have a small aluminum cart that I used on 2nd unit "Hulk" that also uses the seat
Low mode scraping the ground at full gallop is very easy . Unfortunately i'm still on the vest with two Alexas more often than not. On the vest, I have to slide the gimble all the way up the post ,and slide it back before docking (awkward) I have had weight on the MK-V before .the gimble can take it. !80mm anamorphic with 1000 mag. on "The Thing" but at wide open it's harder for the focus puller

Nice.

We've been testing this identical setup on the Steadiseg; that's one of the reasons the new hard mount is so strong. Works really well!

All the best,

Chris

Why not just use a G70 or a Pro-Arm?

I tried the pro arm with black canisters and it drops like a lead zeppelin just like the modified 3a arm. I also like a compact post and to do that , one needs heavy batteries to balance.

wow....

I can't imagine 2 alexas on a freestyle rig....that rig slexes like crazy. The new evo model is better but still.....as a stereographer I would never do that.

ingenious solution.....kudos!

the ALexa M is coming soon.....so yes I doubt you will ever have to deal with 2 full sized alexas again!

Pedro, The PS freestyle rig flexes particularly with Alexa's or just generally?

I love a compacted post. I never, in 2D, Extend my post unless for low-mode. But in 3D and the kind of operating we have to do in 3D; that really goes out of the window for me personally. Do you honestly think you can't do an Alexa freestyle rig with just a single PRO/G70 arm? I know where you are probably coming from. It is SO close to the bone with where every detail of every accesory is placed to make it work. The big issue being getting power into those two bodies. Maybe its just easier to find another solution than argue with a load of jobs-worth stereo guys.

RED-Epics and Alexa-M s are rolling out now. Thankfully that little nightmare should be over.

I used the Freestyle with 2 Alexas on a movie this year. With a pro arm and sled, the 4 black cans were wound up to max. Had to be very gentle with the freestyle to keep the cameras from coming out of calibration. All up with sled arm and vest is 100lbs.

We used Ultraprimes instead of Masterprimess and one camera was powered from a cable that ran along with the 4 bnc cables over my shoulder.

The biggest negative for me beside the weight was the big mirror box and constant flare issues.

Thought I'd add a picture of the 2 alexa rig.
