Would it be possible to use an OFF-AXIS TUNING COIL in order to get enoght
inductance to be able to tune with the Topload?

Ravi's coils is set up now with the toroid removed and 12 bottles for the
capacitor. We don't have enough primary turns or enough primary
capacitance to tune with a toroid at this time. Maybe a real small
one. Maybe after the science fair, some one can donate 5 or 6 mmc caps to
him and we can get this thing going? If someone does this it would
probably be good to solder them together in advance for him, I am ! not sure
he has a soldering iron. His primary cap right now is only about .008 ufd
or .009 ufd and needs to be about 5 times larger unless he rebuilds his
primary with about 16 turns instead of 8. Even then we will need more
