I'm looking at upgrade the original EFP post, to a carbon fibre one - but I can't figure out how it's held in the base, and how I can fit another in there - I don't like tampering with the base with the electronics in, but surely it should be fairly easy? The other question is if there is a connector in the post for the cabling - or something near the base?

I'm trying to change it as I've invested in a new monitor and the new monitor arm squeezes the bottom section of post together, and I don't like putting that pressure on it.

Cheers,

Jason :)

Jason--

Having upgraded several EFP rigs for folks over the years, I think most of this you can do at home without too much hair removal.

The EFP post should be removable without undue force. The lower post should have been cross-drilled and pinned into the electronics/base piece. To remove the cabling, look for several wires to extend from the bottom of the post sections. There are power, video, and follow focus wires each with disconnects. Some are push-pull while others are screw-together items. Just take your time and look carefully.

Once you have removed the wiring connectors, you should be more comfortable with working on the device. Look closely at the base of the post. If the post has been drilled and pinned, you will see two or more holes and tiny pins. If this is apparent, you will have to drill out the pins to remove the post section. If the post has been glued into place, you must either dissolve the adhesive or cut the post and then "dremel" out the remainder to clear the openning to reinsert the new post components.

BTW, what is the type of post you have now? Is it one of the titanium posts? Shiny dark gray with a nice sheen. Very tough but susceptable to impact damage. If it is aluminum, go ahead and clamp that monitor bracket to the post, but try not to tighten so hard as to crush the post material.

If you need further assistance, drop me a line at firebrand@fmis.net.

Hi Brant,

Thanks for the info - will have a closer look tomorrow and see what's what - yes it is the titanium post - bit of a pain with the groove though, that's the only reason I want to change it, otherwise I'd keep it in use - but really didn't fancy attempting this without asking first!

Thanks again, will let you know how I get on.

Best,

Jason

I had the same issue, and had my machinist drill and tap into the monitor arm and put 2 small screws vertically into it to stop the post from clamping down. They act as a spacer in there so the arm tightens down, and as an added bonus, wont spin with the screws in there.

Curious to know which post you are replacing it with. Please keep us updated (With pics if you could) on how it goes.

Thanks!

Hi Brett,

Looking to put a carbon fibre post in there - something that won't get crushed by the monitor arm.

I took the sled apart today, and thanks guys for your help, it was fairly easy to remove it - and now I know how it's fitted - going to leave it apart for noe while I look round for other posts - but from what I gather I'll have to get a similar sized one otherwise my case will be useless!

Will grab some pics when I get chance :)

Cheers,

Jason

Hi Brett:

I saw your EFP photo.
What camera plates are you using?
I have a modified Sony plate in order to use an 2N1 by Jerry Hill for mounting the FF motor.
Tomorrow will leave a pic about it.
Best to all,

Gus.

Hey Gus,

I'm just using the standard cheese plate that comes with the old 3a style donkeybox. The plate you were looking at was probably the lightweight/steadicam Panavision package with carbon fiber rods.

I would like to see your modified sony plate. I had been thinking about doing something similar.

Hi Jason,

I was at Greg Bubb's shop today and we got talking... as usually. I mentioned that somebody was looking for 1.5 Carbon posts... he has a box of the old style 1.5 inner posts as he went to the 1.75 inch ones.
He said to give him a call if you are looking to get a post for a steal... It should fit the EFP or 3A Gimbal.

Give him a call.

Good Luck,

That sounds very interesting to me as well. I use a SK2 post which isn't extendable and already thought of upgrading it. Regardless if the posts are adequate finally, thanks a lot for the info... :).

Thanks for the info Erwin, will give him a holler

Well I have to admit - it was fairly simple to get the post out - just lots of messing with the base to remove the PCB, and associated cables, then just three screws - it isn't the easiest of ways to remove it, but nonetheless quite achievable (and for someone who doesn't like touching the inners of Steadicam!).

Now got to work on a way of getting a carbon fibre post in there :)

Cheers guys for your assistance, was invaluable.

Hi Brett

Here the pic.Sorry for the delay.

Je.. :)
this is closer than the another one.
I can use 2N1 Jerry Hill in this adaptor fixed on the Sony plate.
Best,

Gus.

how is the post replacement going???
do you glue the collars on to the carbon fiber or are things held in place by compression?

i just purchased an EFP base and am going to have to fabricate a post.
i will check as mentioned above...



i was also thinking of making a modular type of attachment along the lines of the GPI post.


does anyone know how many pins the connector in the GPI post has?
i figure if i get a connection with close to the same number of pins i should be ok...

any input is appreciated..

thanks,
david

Hi

People with EFP rigs may find this of interest!!!

It would allow the use of the range of MK-V posts. Hope this helps in your quest David.

Hi David,

The PRO rigs use an 8 pin lemo.
