Sure it's quality... just don't _ever_ forget to fill the lubricator! (no, I don't know that from experience, mine leaks even though I've always filled the luber. :( ) This is something else I'm going to ask my lathe-weilding friend if I try making slide valves. Real glands! Trot, the fox who'll

Thanks Jim, Paul & Clark for your suggestions. One thing that I haven't done yet is use any packing in the piston and valve rod glands. How might packing them affect things ? I don't seem to be getting alot of blow by out of the gland nuts. Is packing gonna put alot more friction in the sys
