Thanks so much for sharing.
As for the extra pole for your Flynn. Go to Home Depot or Lowe's (really any Hareware store will do) ask for conduit. Best part they will cut it the size you need. Just make sure they don't dent the ends. When you measure for the length, make sure you allow for the extra on each side. I have extra sets for twin/throw, standard/queen and extra long for King.
Also, when you get the extra pipe, make sure you remove the little round piece at the end of you Flynn connection. It should show this on the video.
