It can´t be done to a common pivot cause it will lock the blade, so in general we have to use Loctite after adjusting (even in Sebenza 25). I had the idea of making the common pivot allowing fully tightening. Sorry if this is old idea, but I´ve never heard about and would like to know if it has already been done. This is what I intend to do: The pivot has a female nut part and a male screw part. Put a small steel cylinder of smaller diameter than the hole inside the nut before inserting the screw, so that when fully tight against the cylinder the length will be the correct for the adjusting. This way the screw won´t back off. The length of the part has to be guessed, but we can measure top to top of the pivot when adjusted, and top to top when disassembled fully bottomed. The difference is approximately the correct length. The cylinder has to be thinner than the hole to allow it to fall down until the length is sanded to the exact dimension. If it gets stuck, problem. Will this idea work?
