Looks basically the same as my B1 apart from the insert that goes into the ball. As far as I can see that insert with that goes into the ball is a single piece on my B1. Seems like a strange way to assemble the head, maybe the tolerances on the insert and the ball were not right.

glenn,

I see from your photograph that it wasn't the clamp that came loose but the shaft itself. Not good but that does answer my question.

As to the RRS lever clamp not compatible with the Sidekick, Wimberley now makes an adapter plate that attaches to the Sideckick for use with RRS lever clamps. http://www.tripodhead.com/products/AK-100.cfm

The snap collar will not work when the ball is set to vertical to accommodate the Sidekick.

Glenn, this is so very educational for everyone. Especially info like this about a brand new product with design changes. Please, would you post a few more photos of maybe the ball neck opening, up close ? And maybe a close-up photo of the threaded neck insert, maybe at a different angle...................Thanks !!! :D

Jim, thanks for the update on the sidekick. I did not know such an adapter existed. Now I have more things to add to next year's Christmas list :wink:

glenn,

On close examination of my B1 it appears to be the same construction. I do not know how Arca-Swiss joins these two pieces. I would expect it to be a sweat joint or possibly silver soldered. I don't know if there are other adhesives that would normally withstand the the torque on a fitting of that nature.

Mine looked like some sort of super glue, not metal. At any rate it failed the moment torque was applied the first time I put it over my shoulder. And they had not had any failures like this before, at least not any that Precision Camera Works was aware of. It will be interesting to see how fast the turn-around is and what they say about it.

I will post something new when I hear from them next.

Regards and good shooting to all,

Glenn

Thanks very much Glenn, for the additional photos. If you really look closely at the closeup photo of the insert plug, you can see very widely spaced and shallow cut threads on the outside of the plug. With these few and very shallow cut threads, My guess would be some form of "locktite" applied to secure the plug inside the ball neck. Just my wild guess...................Very interesting info about this new product......... :D

Without the glue, the top plug slides in without friction. It could be out of tolerance, or the part could have had lubricant on it when the glue was applied.

Update on the Z1.

I just got it back today. I checked with repair and they used steel epoxy to repair the ball. It looks good and clean and I did a quick test of the assembly over my shoulder and it looks like it is going to hold. I won't know for certain till I take it out on a hike. If it gives me any more trouble I will post again.

The photos I took were forwarded on to Arca Swiss. They were very concerned, this type of failure has not been reported before and they are looking into it.

Glenn, it has been several months since you got your Arca-Swiss Z1 ballhead back from being repaired. I'm very curious to know if you have had any more problems with this newer designed head ?? Are you satisfied with the integrity of the repair ?? Thanks !! :D :D

All the time with a Arca B1, Sidekick, IDM2, 500 f4, 1.4x, 580EX, Beamer and Flash bracket. Never experienced creep,

I use two heads, a full Wimberley and a RRS-55. The design of the one you pictured would scare hell out of me. Looks like the whole thing could fall off. I am paranoid about that because I had an F5, 500mm f/4 AFS, and TC14 fall off my ballhead and it destroyed all three.

So far all is fine, no complaints and no creep on the ball. The repair took care of the problem and I feel confident that it will hold.

That said, I do not carry it for very long over my shoulder assembled. It is very heavy and awkward. I don't want to risk injury to my shoulder. I have a belt and plier holster that is described on this list and I remove the camera from the tripod and carry it on that if I do not want to carry it over my shoulder or put it in the backpack. Works well and if I see something, I can swing it up for a hand held shot very quickly.

When I carry my 500 f/4 any distance, I take it off of my Sidekick. It seems just too risky. Without the Sidekick and going directly onto the BH-1 ball head I have no worries. I am considering getting the insert that Kirk sells to prevent the ball from accidently tilting.
If there are an infinite number of universes, why was I stuck in this one?
