Every time my Star sizer/luber gets up to good operating temperature, with each pull of the handle that unnecessary sizing die set screw starts backing out. You can see the thing turn several degrees with each pull of the handle. I have two Stars, both older and both with the set screw. On my original that set screw starts backing out every time. Also it leaks lube, though not a great. The other one - never a problem. Anybody dealt with this successfully short of heliarcing the hole shut? Big Boomer
