I can't believe I am doing something wrong but I can't for the life of me get my FMS stands together. I am really struggling with getting the long support tubes screwed into the metal base. I have tried all four tubes in all four of the base holes and no luck.

I have been working on the new HT room all day and don't want to break my new stands so I am packing it in until tomorrow but thought I'd check here to see if there is a trick to this.
