My 40 year old Lyman 450 has been leaking lube from the bottom area and I got it empty yesterday and have it taken apart. I googled for info and there were lots of references back to our forum here. A few guys talked about using set screws to stake the plug back into the bottom of the sizer. Does anyone have one done this way that they have pictures of? I have a drill press, cross vice, drills and taps and lots of set screws and short machine screws. I'll be going into town tomorrow hunting "O" rings. Thanks!
