Has any body tried these threading gears

I think you are reading it right--maybe an 80 also to cut .75 and 1.25 threads.
I still have the delrin gears and will try to remember to look and see if I have an 80--I know I don;t have a 100.

I'm thinking my SB9A came with an 80 tooth idler.

I looked at these gears on Ebay, I wonder if any has used them with good luck. I messaged the guy building them. He's saying that he's built over a hundred with no failures. Take a look and tell me what your thought is.

We have quite a good selection of original gears for threading-
