So I have a similar question. I’m trying to replicate this screwdriver handle. What would be the best way to cut these radii? I am brand new to machining still. I am using a Bridgeport.

I assume you do not have a huge rotary table. that would make it easy.

If you have a DRO, you can do what I call manual CNC. Lay out that curve in a drafting program. get an offset curve the size of a large end mill. find the Y value every say X of 50 thousanths and put it to paper. Now move both the X and Y by hand to each point. With a bit of practice you can do any odd shape this way.

If you have a way to spin it and a boring head, you could use those.
