I am trying to make a cam assmbly jig for assembling a multi piece cam as L.C. Mason designed for his Mastiff engine. I have attached a pdf of the jig assemby.
I can't use his total design as the Mastiff is an opposed “Boxer” style engine and the engine I want to build is an in-line 4 cyl., ETWs Sealion.
I want to use the Mastiff type jig so I can harden the lobes before being installed on the cam shaft and skip any possible warping of the cam shaft during the hardening process. I also attached a pdf of the Sealion Cam machining notes as well as a pdf of my attempt at figuring out the angular position of the center points of the cam lobes.
The notes say the Sealion cam rotates clockwise from the timing end.
Would some one be so kind as to review my work and see if it is correct and let me know what to do if it isn't?
The process of making the cam for the “mastiff engine ,I feel, was very easy and I believe others could use it as well.
Thanks in advance
Ron
