Anyone got an idea on how to make a wizard for turning an ellipse?

Let me guess,
Your chess bishop is the problem!
Are you talking about a fixed ratio curve or an involute curve, if its fixed ratio you can do it with 2 # variables and a sub routine.
If you want some code give me some sizes length/dia ratio and I will post an example.

O boy that is not as simple as it sounds :(
I think that Cam is going to be the only way to get that ...

I was afraid it would be complex, I just don't have enough trig knowledge to know where to even begin. I really didn't have any dimensions in mind yet. The different things I would like to make (of course you guessed it the bishop) along with a host of other uses,
airplane prop spinners, candlesticks that kind of stuff. If you have some ideas on the basics, tell me more about the fixed ratio curve. I will search the internet for something to read on it.
I am looking at fairly small diameters 2" to 1" , and fairly short lengths 2" and less.

OK, give me a few days and I will dig out the routines, convert them from Fanuc macro code and post them in a Mach format for you.

An ellipse is what you see when you slice through a cone at an angle. If you need equations try the wikipedia link.

It has everyhing you would ever want to know about an ellipse
Thanks.
