I bought a used Saeco sizer a while back and just started using it some. I'm using a lube that requires heat so I'm using an iron for the heat source. When I apply enough pressure to get the lube to flow evenly I get leakage at both ends of the die where it goes through the sizer casting. I held the top of the die with vise grips and tightened the knurled bottom nut as tight as I dare. The leakage is not huge, but a PITA.
Is this normal? Am I missing some gaskets or something? Assuming that there are no gaskets, do you think a o-ring or neoprene gasket at each end would work?
