Custom battery mount for Archer...

Hi Ed,

 

If this is true I'm more then before in love with my archer... Balance solved and power for everyone... By the way that arm is f$%@#g difficult to adjust. Coming from a very old spring design where in the soft spot you don't have issues (but only there...) setting the right iso and lift for very very slow walks is hard. I end up with almost no iso on upper section and a lot in the front one, so it stays rigid and lifted where I need for bouncing and iso where I need for positioning but like this no way one section will follow the other, is it correct?

 

Next thuesday I might have my first live show with the Archer (a fellow op pass me the job for a double call), hopefully with a Tx camera for a satellite channel. NO TRIAX... YEAH!

Hmm.. on my G50 I usually have the iso nearly all the way up for a very neutral arm and then lift until the arms are horizontal. Hadn't considered having wildly different amounts of each on each section.

 

That said, I've still got a tiny bit of stepping visible in my shots which drives me mad, so perhaps I need to spend more time experimenting with the arm settings.

The same happens to me and drives me mad too. What I experienced today is that almost no ISO on the upper section is very good for fine slow walking but not for other shot. And the two sections work togheter perfectly it's just a matter of tuning the lift after the ISO. If you can try let me know what you think. To test it I shoot an handrail parallel and put the frameline over to perfect test any bouncing. For slow work I think it's a very good excercise.

Got a quick update...

 

Ed came down today with his rig and we measured it up and designed the mount. Took it to the machine shop (after lunch obviously) and its being cut out tomorrow or Monday, so should have it back fairly soon.

 

It holds one V lock battery under the lower rods and it has one 2pin Lemo connector which will provide power.

 

Will post some photos when I get it, but Ed took some photos that im sure he will post up somewhere...

 

 

Pete.

That's great news Pete... I'm very curious...

 

Regarding the G50 arm, I have to correct and apologize for my previous post. I was wrong, I got a very good explanation from an expert op and realize that my ideas were totally wrong, I got confused watching the elbow. The more ISO the better the result, I did try setting the weight after pulling out all the way the ride knob (iso at max) and I come out with a perfect setting for slow walk and for walk in general (I saw it's pretty always slow and precise walk while working). I didn't take a workshop yet and here I even more realize how much I need one.

Hi,

 

Just been at the machine shop, Dave was just cutting out the clamps. Its a slow process, but they are cutting right now, as I type and will be done in a few hours.

Also Ed took this photo, because its pretty cool. Machining an F1 wheel hub from solid.

Also this is my 19-15mm dogleg adapter clamp, which is also for sale if anyone wants one. If you buy one, it comes with a nicer screw! Im sure Ed will fill you in on how tightly this clamps the rods, i'm pretty proud of it, especially since I designed it in the pub.

Quick note on power: after some deliberation, Pete and I decided to parallel in the new battery plate to the old one just by adding a 2 pin B sized Lemo panel connector to the back of each battery plate (there is just enough room in the back of the existing Archer plate to allow this), and then I can just add a cable between them as needed.

 

We talked with a technical guy at IDX about the issue someone suggested further up about one battery charging the other and he didn't seem to think it would be an issue.

 

Personally, as long as it allows me to effectively hot swap batteries on RED shoots without waiting for the camera to boot up, any additional power capacity on top of that is a bonus rather than a necessity.

Hey Ed,

 

Would the plate look like that picture?

The plate will be the same but attached to the clamp as Pete says. The battery will hang under the rods (although you could easily put on the other way if you'd prefer the battery to be above them).

 

The other difference is the plate you linked to has a flyaway lead permanently on it - we are using panel connectors on each plate so you can completely remove the cable if you want.

ED,

 

How do you connect this panel connector onto the existing battery plate? Maybe a stupid question but I don't even know how a panel connector looks like. Maybe a picture?

 

Again, thanks a bunch guys for trying to make our Archers even better.

 

Sebastien.
