I almost spent $150.00 necessary dollars on rather unnecessary equipment.
My tripod, a Promaster 6400 bought in 2000, for the past couple of years has had a loose shaft. It would move/jiggle at the top of the tripod where the shaft, to which the head is mounted, comes through. This tripod has a mast cover that turns to the left to loosen and allow the shaft to move up and down freely and turns to the right to secure it in position as opposed to turning the locking screw.
I took off the shaft cover and spied a bushing the stayed on the shaft when the cover was removed. The top of the shaft is bevelled so that when you tighten the cover, the bevel pushes the bushing up and in to clamp down on the shaft thus preventing all movement, at least in theory. Well, it seems only the lower edge that was in contact with the bevelled inner surface of the cover was all that was clamping on the shaft, prevent vertical movement, but doing little to stabilize lateral movement of the head.
I got some self-adhering automotive thermostat paper from Manlove Auto Parts where I work (p/n MG30). I cut a piece to fit around the outside of the bushing in length and width. I peeled a couple of layers from the outside of this new bushing until it fit inside the end of the cover and when I tightened it up this time, ROCK SOLID. Simple stuff like this can keep your photography going when things look bleak. Share your DIY repairs.
