Quick question that was on my mind and I didn't think to call Jack earlier belt the holiday breaks took hold.

The PRO sleds with quick release bayonets at top and bottom, are they designed for repeated mount and dismount? The screw collars make for quick access to dismount for service and maintenance, but is it encouraged or discouraged as a means to store and travel with the sled?

For Service, I'm sure the screw collars will work well for the occasional disconnect and reconnect (once every month on average?). However, is there any concern with daily or multiple times per month connecting for work and disconnecting for storage/transport?

Have other operators had experiences one way or another? Has PRO already commented on the matter?

Funny thing, having gone through the archives, I knew I had read about this recently. Lo and behold, on the second to last page of the Sled section, there it was! Alec Jarnagin has some thoughts on it. http://www.steadicam...809

Having taken my sled apart and put it back together plenty of times, I wouldn't want to do that on set. As Alec noted, it's too easy to cross-thread such fine threads, and end up with a rig that you can't safely fly.

Yea, the fear of cross-threading is my largest concern, and I'm hoping to get PRO to weigh in once in the new year. I would imagine it's not designed to be a daily/regular type thing, but I wanted to check on people's experiences first.

My intention wouldn't be to do it directly on set, but rather during my usual "set up" and "break down" time that I work into my arrival and departure schedule. I generally pull everything from my car anyway, so while putting things together, I foresee the opportunity to take that additional 3 minutes to assemble the sled. I have the big anvil case I could use for travel, but it's so enormously bulky for the short drives I generally take. Air travel, I'll use it without hesitation... but getting to set that's 10 minutes from my place seems like overkill.

I've also considered getting a sled sock through Modular 51 or others, but I haven't pulled the trigger on it just yet. Exploring my options.

For day to day driving gigs... No case. Passenger seat. Seatbelt.

About 80% of shoots are using the Alexa now and it's great to just leave the rig mostly outfitted with cables and my accessories. Saves even more time.

I honestly think your over thinking this a bit, but that being said:
I did a show as an assistant with Chris Haarhoff on steadi and he stored his sled in a pelican case with the battery base removed, seemed like we stowed it in there when ever it wasn't in use. Must have connected and disconnected, that battery base every-other day for three months. We never had any problems other than occasionally forgetting to plug the lemo connector in. I mean he helped design the damn thing so if he did it, I would think it would be ok.

Was Chris using the newer HD components, or older SD components? The old SD components and connectors were able to stand up to repeated disassembly. The connectors (coaxial pins specifically) in the new HD components are much more fragile and subject to malfunction under repeated mating/unmating. I would recommend disassembly it only if absolutely necessary.

Yeah this was a number of years ago, before the HD sled existed. It was a stock PRO-2.

Looking for more definitive proof, but I'm pretty sure the LEMO connectors in the PRO and XCS center posts have a coupling/decoupling rating of 2000 cycles. My concern is for the possibility of mechanical danger such as cross threading in the collars, not so much with the LEMO connectors.

Obviously contact GPI for their input. The sled sock does seem more appealing from a simplicity standpoint, as well as quick storage during company moves.

We'll see what GPI suggests, But the Coaxial pins for the HD signal in that 19? pin lemo connector might not make it if repeatedly connected and disconnected..

Now If my Pelican 1650 case was 2" longer on the inside length...... Just 2"....! I'd be able to fit the Pro Gen 3/XCS sled in there just fine.

I've often thought about the sled sock for local jobs, it's quite appealing.
I'm however the type of person...if I don't cover my ass, the one time I don't something bad will happen. We've all spent a lot of money on our gear, I'm protecting that stuff with all my might. I'll allow myself some extra time to break it out and set it up. I will subject myself to the ridicule of driving my Grand Caravan to accommodate all the hard cases.
I've heard all the minivan jokes btw....go ahead, try...I've heard it.
:(

Two Thoughts.

1) The more you plug and unplug that massive lemo connector on the base of your sled and the more you thread and un-thread the mount, the greater the risk of damage . Damage means down time. Down time means no rental. No rental means no money.........

2) Sled sock, sled sock , sled sock.
