I made one of these some time back when Tom first posted a photo of it. The design that Tom has presented mounts on the front side of the tool post. It puts no load on the tool post or carriage other then what little force it takes to keep it from spinning. The original has a spud on the back so it can be held in the tail stock or in a turret. Only reason I can see for holding it there would be if you were making numerous parts that needed to be knurled.
I cast the plate for mine, by the time I made the pattern and did the machine work on it I could of used plate and been time ahead.
you will need .5 inch diameter knurls to use the full capacity of the center hole.
I used .5 inch brazed on lathe bits for the stock to make my knurl holders out of.
I made mine as shown in the MSC catalog, but could easily change to Toms Design without loosing any strength or rigidity.
