No. The diameter of the pin you are looking at is 1 3/4" The reason I know that is I just got two 1 3/4 Fenner locks in the mail.
That pin that is through at an angle is just a test to see the angle travel for interference. He is setting it up to use on the 58 inch mill table it is on. But he will need a 8 x 18 inch riser for the head to increase table to spindle hieght.
He bought this rotating 24 " table to make a riser for the series II. he is ordering a piece of 18" diameter x 2" wall seamless cold roll pipe to make the spacer. The table is setting on the craftsman tool box. That table has to weigh every bit of 400 lbs
