Todays Project - What did you do today?

The check valve quit checking in a friends compressor. Tore it apart and found a plastic spool broken. Thought about making the new one out of brass but was afraid it might not seal on the flat valve seat so machined one out of an old screw driver handle. The air out of those little compressors must get some hot. The black blob is the first try, made the next one out of brass and it worked like a charm.
