Foundry work!
I expect you have as much experience in that arena as I have.......... I have an induction furnace, which would allow for casting steel, stainless, ductile and gray iron, and have a crucible furnace planned for non-ferrous alloys. .............As a result, I have much to learn.

At hand operated speeds this is true, if you investigate cam profile design you will find that an important part is that of the closing side of the cam lobe, ensuring that the valve/spring/collet etc. combination can follow at optimum RPM, otherwise valve bounce will ensue.dly31 wrote:Of course there are frictional losses and the springs don't return 100 percent of energy but I have noticed that camshafts with many lobes tend to be pretty easy to rotate by hand. So the springs do seem to return energy as they extend.
