I have been promising to make an understandable description of how I
have made the camshaft for my engine. So I finally got a little time
that I could play, and here is what I came up with.
What the image shows is the end view of the cam blank (from the plans) while it is mounted in a three jaw chuck (or whatever) on a rotary table. The milling machine is set to the correct depth of cut, and the table is fed into the cam blank. The rotary table is then turned until the correct amount is cut from the blank, leaving the proper duration for the lobe.
After the cam is machined, the edges of the lobe are filed by hand until smooth and rounded, as seen below.
The images shown are not, in any way, proportional to the actual camshaft lobes. When making the animation, I simply started drawing, and I did not measure anything.
When making the lobes, you must be careful not to loose the position of
camshaft when moving from one lobe to another.
Thats all there is to it.
So, tell me what you think.
