I had better let you know that Eric has been rather ill for the last few months, and I think it is best if you let him recover a little more before pestering him for plans.
If you are just after making one or two cams, this grinder isn't most probably the best way to go. It is a rather large machine to have sitting around the shop not being used, and also it could get rather expensive if you don't have most of the required bits in you stash boxes. Even though I have most of the bits to make one, I did price it up to make if you started from scratch, and it could easily cost you a couple of hundred bucks to make, depending what sort of grinding head you were going to use and the type of drive system that you would settle on.
So for those that think it would be a cheapo way to make a cam, as I thought, it most probably isn't.
I think it would be more suited to club, rather than individual use, where it would get the amount of work to make it a viable cost effective proposition, or maybe a couple of people who live within easy striking distance of each other. Unless of course you went into making model engine cams big time, but as a few people have already found out, don't give up your day job in the meantime.
If just making one or two off multi lobe cams, then you would be much better off doing it the old way that ET Westbury did it, and later Bob Shores. That is make a little holding and setting jig for your lathe, and use that. That is what I did when I used to make IC engines, and is a very satisfying and easy method. You can easily cut one lobe in half an hour.
In fact, I am positive Uncle Marv has a proggy in his collection for making cam lobes using coordinates on the milling machine.
The main advantage of a cam grinder is that you can process pre hardened blanks, whereas with the manual method, you either case harden or full harden after the lobes are cut and shaped, and you run the risk of distortion during the hardening process. A thing I never had happen, but I have been told it sometimes does.
This post isn't to put you off wanting to make one, but a little information to bring you back down to earth.
