Something new here. Any comparison happened yet?

Imran,

you are standing right on top of it.

You should start with the Forum archives. It's in bits and pieces but I think it gives you a good overview about gimbal maintenance.

Hope this helps.

Alec, Peter, Jamie and Eric thanks for the input.

Thanks Jamie and Peter,

did you ever consider this magic ACF-50?

Continued in ?What do you pour in your gimbal??

new topic

Alec,

I was searching the forum about gimbal service and stuck on yours and Will?s posts.

Time passes quickly.

So Will what do you pour into your gimbal?

What about leaving the gimbal bearings with out any lube? The bearings turn a amazingly long time when dry.

IMHO the forces inside the bearings don?t get close to there design specs. Cooling down is not needed. The parts don?t move very much except for switches and whip pans.

An advantage could be that sand or dust could fall off the bearing easily.

Thoughts, suggestions?

Anything new about the lube job at the gimbal service station.

I'm currently cleaning my gimbal and wondering what is best for the bearings. Does the lube has any impact on the friction gimbals have or don't have?

Chrosziel has a replacement for the Sony-V-mount tripod plate under the Camera.

It is rigid enough to work with a remote focus like Bartech or Preston (15mm) and it is still compatible with your existing tripod plate.

Hi,

IMHO there is a lot to learn about carbon fiber and other materials in bicycle design

Hey Will

maybe this is a solution:

You can get your needed 12V out of two small Li-Ions used on Sony DCR Camcorders.

I always calibrate from the infinity to the close focus marks. IMHO it is not possible to reproduce the exact tension like a autocal remote focus. It is not necessary to hit the exact same mark on the lens while inserting the gear. It should be close to the middle of the lens range of travel, to spread the resolution equally. This way I had very reliable results.

Sorry, for misreading your question.

Best

Depends on the lenses you use.

With video lenses this is maybe an option but with lenses for 16/35mm or cine HD it is not. Every lens has it's own markings. Zeiss use 7 different scales for every focal length on there standard lenses, Cooke makes a unique one for every single lens.

Hope this helps.

yeah, u can put the bubble any which way wherever u like. I ve put it directly underneath my post because....

 

on paper (maths) the closer it is the the centre of rotation the less it will suffer from centrifugal forces when whip panning. ..... i.e. the further the sensors are away from the middle of spin the more they ll be tricked to give a false reading

<{POST_SNAPBACK}>

Thomas,

now I'm a bit confused, you could place the bubble anywhere you want, given that it is compensating G-forces.

Best

It has more sensors in it to measure and calculate against G-forces.

<{POST_SNAPBACK}>

Hi Thomas,

does it mean this level is only "sensitive" to gravity and is completely ignoring G-forces?

Hey folks,

over 240 views and only 12 votes? Where are all the op's with a back mounted harness? There have to be more than 12.

Come on, this is not an election only a poll.

I had a chance to see and fly Garrett's new Klassen front mounted back mounted vest (don't know a better way to describe it) at the Tiffen party the other night.  Not owning a back mounted harness (and only having flown one a few times) it's hard for me to say if I prefer the back/front mount over the back mount.  What I CAN say is that I like it!  I think it takes the best of both syles of vest/harness and combines them.  I'm looking forward to hearing what operators that already own a backmounted harness think of it.  I believe Garrett's vest will be at the Steadicam Guild get-together tonight for any attendees to try.  Plus, there's free food tonight, which is another reason to go.

Any experiences? Comments are really appreciated.

Hi Stephen,

thank you for the photo.

Hi Howard,

What kind of diodes do you use? How about voltage drop of these diodes.

Hi Flemming,

Sorry this was the wrong link. Not enough power.

Here is another one:

Ron,

the 420 doesn't need the adapter. It's possible to take apart the "TV cradle" and make a custom cable with the plug that goes in the AV 420.

Hi Flemming,

Hi All,

I'm curious about this question for some time now.

It started with the discussion "Why a Backmounted Harnass works.....". I shifted this back and forth in my mind until I saw the pictures of Walters and Garretts front mounted / back mounted Harness. Thank you David and Will.

An Integrated low profile arm. That's what Walter and Garrett invented.

So why does it work? Jerry, Alec, Mitch and Jamie are right. It is not because it is back mounted. It is because the waist pad/door and the chest pad/back support is one piece. There is no flexing, bending or what so every your back has to compensate. It is possible to distribute to the load to your hips and over the entire back and freeing your chest.

To get back to the poll.

Is there a greater demand for the back mounted harness from operators that used to have a front mounted vest without additional back straps or is there no relation at all?

Best

Emery,

Sadly everything and more sadly everybody is compared to a competitor.

I respect your point. Less compromises, better product. I guess I'm not ready for the CanaTrans at the moment but I'm sure that I will get back to you.

Hi CP,

what are you using to hear the director (don't know the phrase)?

Regular headset have a good damping but the cord is hindering. Make sure they have a wireless solution for you with a good! headset. I use custom made ear plugs like talents wear for in-ear monitoring. Ah, in-ear monitoring. The wireless stage. There are sometimes tons of sound transmitter and receiver on stage and for each a backup channel/unit. Let the production know what frequencies you need to use for remote focus. A remote focus or the own wireless sound link is easily blamed by the stage manager.

Best

Hi Emery,

thank you for the information regarding PAL and NTSC audio modulation and channel/frequency differences.

Hard to smoke up and no backup unit needed. Looks like fools proof.

You state that the PAL unit matches European channels and therefore is the way to go. But I'm not sure to buy a unit just to please folks in video village with consumer electronics like the Sony Watchman with the very rare not produced anymore tuner or the Sony 19" "often build in video combos" tuner. As you said, it is the tuner. BTW the really cheap handheld monitors work quite well with the Modulus.Transvideo has tuners that can be set at US-Modulus channels and work quite well and they are very common, diversity tuners are also an option.

IMO the CanaTrans is the better unit. But why spending twice the money just to have a better picture on a poor tuner? I think to a great extend there is an environment in Europe that fits the Modulus and it's frequencies. Why not build a Canatrans "light": US channels, no sound, PAL & NTSC compatible, closer to the competitors in price.

I have the datasheets on both if you want me to send them to you.

Hi Charles,

I'd love to have a look at both.

Robin,

no worries, learned something new. What would be the effect on Ni-Ca on the long run?
