I purchased a used Star as a Christmas present to me. I warmed it up to work on get the old lube out so I could start with fresh lube. That stuff was like rocks. Any way on to the problem. When I removed the top piece where the lube goes in, the rest of the pieces stayed in the sizer. I cranked the screw all the way down until the old lube stopped coming out. How is the top piece attached to the rest of the pieces inside the luber and how do I get it out? Thanks in advance for your help and suggestions, Mike
