Valve Spool 6
6-Jun-2006
The Valve Spool blank is checked in Gordons lathe. I
choose to use bronz aluminum as the material is harded\r than other
bronzes.
Finally I have cut the ring grooves and am finishing
the steam passage. The groove on the far left is a practice slot. The
tool was not ground to the groove size, rather, after plunging the
groove, I move the carrage +/- 0.003 to cut the finished groove. This
also assured that the sides are straight.
The groove second from the left is the left egde of
the spool.
