Mount the Vertical Column

What happens here

With the base and legs assembled, position the main vertical support column into the central receptacle on the stand's base. Align the pre-drilled holes in the column with those on the base. Insert a large bolt through these aligned holes, secure it with a corresponding nut, and then insert a cotter pin through the bolt to prevent it from loosening. Use a wrench to ensure the connection is tight and secure.

Goal: Securely attach the main vertical support column to the assembled base.
