BatteryGrip/Gimbal Problem Solved!

I've observed in the past how the utility of my Benro gimbal head was impaired because the battery grip on the camera (both K-1 and KP) wouldn't clear the angled portion of the vertical arm where it goes to meet the horizontal part that houses the quick-release clamp.*

I've been thinking for a long time, well, since I got the first battery grip, I guess a couple of years ago. I was thinking of setting up my milling machine to make some kind of adapter, but that's such a pain. There was a time when I was patient enough to do all that high-precision machine work, but I ain't got no room for that now. Very frustrating, though, to have my nice (and very expensive by my lights) gimbal head limited to use with long lenses (where I can attach the "foot" of the lens rather than the camera).

So here's the solution I finally hit upon. Still a bit of a hassle, but at least the thing works. I got a "[Pro]master dovetail macro sliding rail" (Dovetail Macro Sliding Rail), theoretically useful for adjusting the distance between the focal plane and the subject in macro photography. I wouldn't recommend it for that, but I suppose it COULD be employed in that manner. The QR clamp gizmo just slides back and forth, it's not a four-way, and it has no screw, gear, or crank that would make precise adjustment possible, and it's pretty loose. However, after removing the gratuitous camera QR base plate, it's possible to rotate the clamp ninety degrees, which is what I did, so the camera's direction when clamped-in is the same as the orientation of the rail once that's clamped into the head.

There are two advantages to that (aside from the theoretical possibility that I could use it for its originally intended purpose): one, it allows the camera with a non-footed lens attached to be mounted more fore or aft than would be possible otherwise in order to assist in achieving optimum balance; and secondly, it elevates the battery grip just far enough to clear the obstruction easily.

* I mentioned this problem in two earlier threads and never got any response (though I did not ask for any):

I don't have or need a gimbal, (at least right now but I'd like to) but this is interesting, and I applaud your ingenuity Dan. I know with a gimbal balance is everything and it looks as though you've just made it more useful. How about a couple of photos of the rig?

I should have done that while I was taking things apart & doing the construction. But I do mean to document the problem and the solution (any day, now). I'm in the middle of some serious computer surgery right now, so it'll be a few days.

This is additionally interesting.
