Floppy TLR Wind Crank
I have a couple of TLRs -- Mamiya C33 and Ricoh Ricohmatic 225 -- with winding cranks that do not stay in position, whether folded or upright. Anyone know how to cure this? It doesn't see to be a matter of whether the pin that holds the crank in place is pushed in too far, or not enough, or is squarely in place. There's obviously some sort of camming action that needs to take place, but I don't know how to achieve this. Thanks.
