My Lyman luber sizer works great until I have to add more lube. I have a terrible time removing the pressure nut. When I turn the pressure screw the pressure nut rises just as it should until its top is flush with the top of the tube, then it starts turning round and around and not rising. This is at room temperature (no heated lube). The only way I can get it out is to jam a screw driver against it to hold it in place and crank on the rachet quickly - it eventually catches and cranks it up high enough so that I can see the O ring and get a pair of pliers on it to hold it still while I turn it the rest of the way and get the nut off the top of the threads to remove the nut and add more lube. Then I have to put it back together knowing I'll have the same problem the next time.... Do I need to replace a piece (buggered threads?) any ideas for work arounds? Am I missing a step in the removal process?
Thanks in advance -
Mike
