You might be well advised to buy The String Book by Ralf Wichman(Braco). This was reprint ( could have been a pirated copy) by Tannens of his original work, 'Floating Routines For Table & Stage'.
It contains a number of Floating rigs and is cheaper than the original book.
I think Magic Books By Post still sell it.
Also the little & cheap book, Floating Ball Magic by Roy Fromer, which carries a variety of methods; mostly practical. Again MVBP
Then there is the Fu Manchu/Mohamed Bey little manuscript 'One
Man Floating Ball'
IF you must float in the open & covered the obvious order is covered first; creating mystery then out in the open.
The Silver Moon sounds like the version, Indian Moon, put out in the early 50's by Max Andrews' Vampire Magic Company. This was by Lenz and began, as Zombie, under a cloth then out in the open, via a circle of IT.
It cost in 1956, 55 shillings.
San Yen (Colin Hughes) featured it in his Chinese Act. He wrote part of it up in his Abra Series, describing & how to make, the open fronted box from which the ball arose using the Zombie method. Very simple but so effective.
I have performed, my favourite trick, The Floating Ball for over 30 years and have a file, some 3 inches thick on the various methods.
At one time I had 10 different makes of the FB but always go back to the 2 my wife constructed back in the early 70's
It took a year to rehearse with Barbara learning the routine, as well, so I could watch it and correct it. At one point in time she could perform it better than me!
She made, the Ball & other parts of the apparatus & her late father, made the table, out of which the Ball floats & returns to.
There is no stage rig. It takes about 3 minutes to set up.That is what took the most working out.
In July 2007 I showed it as the Finale to a 2 hour lecture on Tricks. I thought it was a tired performance but the watching magicians really enjoyed it.
I was quite amused by a long standing professional performer who said,
'I understand the principles of the Floating Ball but sitting 6 feet away from you, in a fully lit room; you bring in a table, set it on the floor in front of us & I cannot see, how you floated it over this side, then across to the other side, in front & behind the table and even over your head.!!'
I didn't reveal my method, based on the classical methods, because that 12 months was very hard, but very rewarding, work as was the 30 odd years that followed it.
We can spoon feed magicians too easily at times by giving them materail which has taken, in some cases, years to acquire & perfect.
Though, young Illusionart, I am prepared to discuss your possible version privately if you need help.
