Where does one find balls? :) If you need more than two, try-
http://www.mcmaster.com/ Go to the
very bottom right of the main menu, under the heading of "raw materials and
springs". Choose "metals", and you'll get a menu of all types of
metals. Choose your metal, then chose the shape (bars, plates, balls,
etc).
Finn, did you
bend the 3/4" tubing that you used on your current cores? If so, how tight
of a radius can this be done. Since I haven't added any hose fittings
to my system yet, I'm starting to think about maybe using 3/4" tubing for
the fittings, and silicone hose.
Cheers,
Rusty (too
many options)
