Ummm, mine is built into a sideboard I made, and there is no metal to get
the tubes started, other than the ballasts mounted in the compartment above.
It starts fine.

You do not need the sheet metal if you build the unit by assembling several
of the the two-tube holders with integral ballast. Just make sure to tie
them all together to a common ground.

When assembling units with individual  bipin holders a piece of sheet metal 
behind the tubes is sometimes needed to get all of the tubes to come on at
the same time. Others have achieved the same result by just lapping a small
wire over all of the tubes.

I'm sorry, I don't understand this.

In honor of Halloween, one of our local hardware stores had 40W
blacklight flourescents, mounted in cheap fixtures, on sale.  Rigging
them up tonight, with any luck.
