Valve Stem Lathe Project





 
 
This project began with the stock piece of brass shown in the second photo.  With this stock piece, it was our job to copy an already existing valve stem.  To complete this task we needed to take very specific measurements, face both ends, drill and tap one side, and turn / use a die on the other side.  Most of the steps were pretty straight forward.  The hardest step was making sure your measurements were spot on (give or take 0.002"-0.003").
