But
we'd better be on our guard, anyway," said Bob, rising to get the
soldering iron. "Whew! but this is hot now, all right. I'll let it
cool a bit, and get the condenser ready for soldering."
CHAPTER XIII
THRASHING A BULLY
Stripping a length of copper wire, Bob nipped off two short lengths
with his pliers and fastened them to opposite sides of the condenser
with small staples. Then he brought all the tinfoil plate terminals
on each side in contact with the wire on that side, and connected the
terminals with their respective wires with a small drop of solder on
each. Then he produced a roll of ordinary bicycle tire tape and wound
the whole thing neatly in this, leaving only the ends of the two
copper wires projecting a distance of perhaps a quarter of an inch.
"There!" he exclaimed, "we can solder our other wires up to them when
we come to connect up the set. It isn't very fancy, but it ought to
do the work."
"Gee, Bob, you must have been studying up on this," said Jimmy. "To
look at your work, any one would think you'd been doing this all your
life."
"I did look it up after you fellows went home last night," admitted
Bob. "This condenser isn't made just the way they say, but the
principle is the same, and I guess that is the main thing."
"We won't worry about how it's made if it only works," said Joe,
"and I guess it will do that all right.
