Peter,
I agree with Jerry on the mechanical correctness of the Rolleifix ( as =
with most things), though I think there probably IS some value in =
spreading the stresses more evenly across the bottom of the camera. A =
lot of the problem doors I've seen are mostly bent where the tripod boss =
attaches to the flat part in the center of the door. The real problem =
as Jerry says, is that the aluminum of the door is very thin and quite =
soft. The Rolleifix is able to transmit most of the torsional loads =
through the locating pins in the camera frame. Sending loads through =
the feet would not be as good as that but would reduce the door flex and =
be somewhat better than just loading everything on the tripod boss in my =
opinion. If you're not going to use a Rolleifix, this arrangement =
sounds like something significantly better than nothing, but I'd still =
advise being careful. Wish Rollei had made stronger doors.
Gene
