Trouble creating a threaded post in the tabs in this structure

[Anonymous]

I will appreciate any help I can get.  

I have made another circle with the same diameter as the tab thinking that I could use the extrude tool, but it is not attached to the structure, and I get the hole in the middle of space.

Hi,

Thanks for posting. I am having a hard time trying to figure this one out.

Can you show another screencast where the entire workflow, including the place it fails, is apparent? I'm glad to help, but need more info.

Thanks,
