Portrait orientation on tripod - camera slip
Sorry if this sounds like a dumb question, but how do you prevent the camera from twisting under its weight when positioning it in a portrait mode?
My old point-and-shoot (Canon G4) had a smooth hole next to the threaded mount at the bottom. The quick-release plate of the cheapo tripod had in addition to the mounting screw a pin to match that smooth hole, so that once screwed to the bottom of the camera -- you could not twist the camera relative to the quick release or tripod. My D-80 does not have that additional hole.
My Bogen 3126 head only has a single mounting screw. If I attach it to the camera, and then "flip" it so the camera is in a portrait-mode orientation, the lens (70-300 VR) will try to twist the camera down; the only thing that will hold the camera is the amount of tightening torque applied to the mounting screw.
Am I missing something? Is it really only friction and tightening that suppose to hold the camera? Am I not suppose to mount the camera in portrait mode?

I suspect that if you have a generic flat plate, you may not be able to tighten it enough to prevent the rotation you are describing. Most of the custom plates or L-brackets are contoured to match the base of the camera, or have a lip that wraps one or both edges.

The 3126 head doesn't have an integrated QR system. It just has a flat plate with a rubber pad, I think, with a 1/4-20 screw.
If you have slippage problems, the solution, I guess, is to replace the head. Many of the proprietary QR systems can have twist problems, which is why many of us spend a fair amount of money to get into the Arca-Swiss system with it's custom plates designed not to twist. A less expensive system is something like the Bogen RC2 system, with an Architectural plate, which has an anti-twist lip on the plate.

Most of us have been in your position at one time or another. Even with a heavy duty 3-way head and a camera plate somewhat contoured to the body and a propriatary Q/R when you turn the head 90 degrees with a heavy lens on it it will creep.
As Neil said, The way around the problem is expensive. You can use an Arca-Swiss (A-S) type body plate with an A-S compatible ballhead, or for the most stability an A-S L-Bracket on your body then place the side plate of the L-bracket into the A-S clamp on your ballhead.
The body will be centered on the ballhead. This reduces the lateral forces (torque) acting on the ballhead, thereby providing additional stability.

Thank you all for the helpful replies!
I read the (good) available info on Nikonian, as well some additional online resources.
As I mentioned, I plan to get a QR to mount on the 3126 (because I have it on a 3211 tripod and I want to make it useable without too much $$$). There are several compatible Manfrotto ones, but indeed -- none that will directly "accept" an Arca-Swiss dovetail. That is, unless I decide to go the VERY cluncky and twisted way of mouting this compatible hexagon clamp to the 3126, and then attaching this Arca Swiss clamp to it...
So, here's my plan: I'm going to get this Kirk clamp and attach it to the 3126 head. I will probably have to drill and add a second screw between the head and the clamp, to prevent this quick-release clamp from being able to twist relative to the 3126 head. For $60 this will turn my 3211/3126 setup into an "Arca-Swiss" compatible.
To the camera side, I'm buying the Twist-resistant plate, or maybe even splurge for the L-Bracket...
By doing so I can get my solid, heavy 3211 tripod with 3126 head (which cost me together $75) to quickly connect to my camera with an "Arca-Swiss".
Problem with this is weight -- this combo is going to be 7-8Lb. I'd like to get in the (hopefully not-too-far) future, a lighter travelling setup, and keep the 3211/3126 to be used primarily at home. The current plan for that is:
Feisol 3441S or 3442 -- $300 @ 2.2#
Feisol CB50D head -- $160 @ 1.3# (or Cullman 35 @ 2.2#)
Replace the QR clamp (Feisol or Cullman) with Giottos MH-657 or Kirk QRC-2 (either is about $60) to get Arca-Swiss compatibility (do i really need to?)
I'd appreciate any suggestion on assembling such a travelling tripod setup for less $$$...
BTW: I found this thread, this thread, and this one to be extremely informative and helpful about this issue! Thanks to all that posted.
