As part of a short term project I removed one of the legs of an MG3 AA tripod. Turns out I didn't really need to do that, but now I need to put it back together and am having some difficulty with the coiled spring.
The tripod locks open via spring tension on a locking assembly (don't know the proper term). The coil spring has two fingers, one at each end of the wrapped coil, which go into corresponding holes in the locking piece and tripod body. The locking piece has non-concentric cylinders that provide a sort of camming action, which can only go into the leg holes and tripod body in one way.
Problem is, the coiled spring has to be wound 1/2 turn to go into the mating holes to provide the required spring tension, and I can't figure out how to make that 1/2 turn before installing the locking piece. Is there some sort of special tool to let me wind the spring enough before inserting it into the two holes, or a trick perhaps?
I do plan to order John's tripod booklet from GermanManuals.com, but in the mean time I figured someone here would already have the answer.
Perhaps I'm not making myself clear, so here's a picture of the parts as disassembled. You can see the fingers on the coiled spring, the hole in the tripod body and the off-center camming cylinders on the locking piece. The coil spring fits inside the cup on the locking piece.
