Hi you all,

As some of you know, I just bought the Nat Massey's rig, and job after job, I'm learning this pack. I've just did a video shot, and I realized I miss some gears.
Does anyone can tell me how many lens drive gears we should have to 'sleep well' ?
I've been seeing the Jerry's website, but I still don't know wich one I have to order !!

Thanks guys for helping.

Chris:

Don't know what lenses you are using, but the typical set is 32, 48 and 64 pitch for cine style lenses (32 being standard) and .5 and .6m for video. Fujinons use a .4 for iris but I think this may be the same as the 64 pitch lens (anyone confirm this)?

Hey Charles.

Yes the 0.4 is the 64 and the 0.8 is the 32.


A complete modern gear set would be:
Wide 0.8m/32P, regular 0.8m/32P, 0.6m, 48P, 0.5m, 0.4m/64P.

Additional gears that you might never use are the Iris gears for the Zeiss T2.1 and the Zeiss T1.3, They are rare and expensive, so neglectible.

Hi Chris
There are the main gears you will ever need .

3 x 32 pitch / 0.8 is the gear on cine lens Zeiss ,S4s,Panavision Focus,(I have several sizes wide as well .25"and .50"wide)
1 x 48 pitch gear is used on a Panavision zoom
1 x 64 pitch gear is used on a panavision Iris
3 x 0.50M gear is used on Angenieux- Canon -Schneider Video,zoom,focus.
3 x 0.60M gear is used on Fujinon- Nikon (Video) for Iris (All video lens)
I sleep very well with this kit
All the best

Chris,

Not sure why you started another thread on this same topic? It will likely get pruned out so I'll respond here.

It would be helpful it you told us which motors you are using, as you were asking where to get additional gears.

Hi Charles, yes you're right, I made a mistake unfortunatly creating a new topic. Here is bellow my previous anwser, and I gona try to close the new one.
I use to work with 3 anological preston motors, and I'll post some pics of the gears I already have.

"Hi you all,

I first want to thank you all one more time, for your quick answers. I already have some gears because of Nathaniel, I first have to identify each one (may be to count tooth by tooth !) and look for those I'm still missing. I'll do this and post a picture this afternoon (gmt).
Where do buy some, Jerry's ?"

Thanks,

Chris, from Marseilles, south of France.
