The young inventor explained that he hoped to find a way to mold the
transducers into a continuous plastic sheet. This could be applied to
the hull of a submarine in a single operation.
"But this time we'll have to do it the hard way," Tom added with an
apologetic grin.
A jetmarine was hoisted into drydock and the work crew swarmed over it,
rigging the transducers. Would his experiment succeed? Tom wondered.
Hopefully, he set to work assembling the electronic control unit.
Bud helped the men on the hull for a while, then descended through the
hatch to see how Tom was progressing.

"I'd go gaga trying to keep track of those circuits," Bud said, as he
watched Tom installing the delicate transistors and other components
with an electric soldering gun.
The young inventor grinned. "It'll be simple enough when the control
unit's all put together," he replied. "Just a single on-off switch and
one test circuit."
By noon, after working at a frenzied pace, the job was done. Tom thanked
each one of the men personally. Then everyone went to eat lunch.
After the meal, Hank Sterling asked, "How about a detection test to see
how she works?"
"Coming right up," Tom said. "Want to skipper the jetmarine, Bud?"
"Sure do!"
"Okay.
