Since I now permanently use the tripod for a year with the heaviest equipment, I want to give all those a little tip, have problems with your plate. The plate is mounted on the center column with 3 rivets that had been loosened after a few days. This had annoyed me and what was to eliminate this. Since I had the idea of the dish bottom, at the point where the center column in the plate just engaged all around a few drops of superglue (but its industrial adhesives) to let reinlaufen. People I tell you, because nothing moves more, and the strongest in 11 months exposure. That sits as firmly as if the parts are welded together, it simply tries it works perfectly !!!
