"It'll be tricky work, and you'll have to wait until your cut edge has cooled before you hook on the rods," mused Don. "But that's the ticket."
"Which floors do you want?"
"Have you got a scale drawing of the Solar Queen?"
"Sure."
"Then this is where my tablecloth artistry falls flat. The focusing of an electron beam depends upon the electrode spacing and the voltage. Since our voltage is fixed if we take it from the driver electrodes, we'll have to do some mighty fine figuring. I'll need that scale drawing."
Channing's tablecloth engineering was not completely wasted. By the time the scale drawing was placed before him, Channing had half of the table filled with equations. He studied the drawing, and selected the levels which were to serve as electrodes. He handed the drawing to Hadley, and the power engineer began to issue instructions to his gang.
