No worries Bob. I had to giggle though as I thought I was bad at explaining things but that article made me look like the Zen Master of explanations.

The standard 9" lathe has a top speed of 700 rpm with the single drive vee belt pulley setup. I have high speed pulleys on my lathe. I was running the machine at 1200 rpm. The highest speed it will run at is 2650 rpm. I used a Kennametal CCGT 09 T3 04 KC5025 grade insert in a Kennametal SCGCR 1212 tool holder.

Here is why. Be like hanging from a rock face by a fingernail. I had thought of using an angle on a faceplate but what I ended up doing worked O.K. Even if I could have held it in a 4 jaw, centreing the work would have been hellish.
