Bandsaw Table Upgrade Parts Identification

[shoedo]

I acquired a bandsaw table upgrade. I didn't notice that it was missing a couple of minor pieces until I reviewed the photo at the Shopsmith website. Can you tell me what the black piece is in the lower right side of the photo and where it is installed and what is its purpose? New Shopsmith owner. Can't say Shopsmith user since I am still researching how to learn to use it safely and correctly. Thanks in advance?

What is that cylclintrically shaped item at the bottom right corner of the first photo and where is it installed?

It is a set screw to set the 90 degree reference point for repeatability. It can be seen in the lower picture as the single upright on the far side of the table.

In the third picture you can see it sticking up from the back edge of the underside of the table. It is a set screw used for a stop to set the table at 90 degrees to the blade. The old cast iron tables used a bolt.

And the nut is a lock nut for that 'set screw'(kinda long fer a 'set' screw).
