Good afternoon guys,well after reading 1961 post and Phil concur with 1961 got me thinking about what was said and a light went off.So I went looking at couple different manuals that I had down loaded but nothing.So awhile back I order a manual from Tony in the UK which I keep it in the house only,well I be in the manual is a good drawing of the parts which includes just what 1961 was saying but it don't show the split pins but it shows the screw.As 1961 saying the split pins is what allows the small half that kinda floats as the screw is adjusted.The larger piece is held in place with a bolt that goes through the slide.That bolt also has a oil hole that allows the cross slide nut and screw to get oil.So thanks to the help here,I now understand.Thanks guys
