Kite Studio manufactures the central hub that holds the bubble wands. Felix Cartegena's original bubble machine plan was published in Kite Lines Volume 12 Number 3, 1997.

Plans for the bubble machine can also be found on the web: Go >>>

All hubs are now made with 12 holes for 12 wands. Some plans call for a 6 hole hub, if that is the requirement for your machine, then skip every other hole. Bubble wands not included.
