While the paper was soaking this up, Joe cut out a corresponding number of tinfoil squares, leaving a projecting tongue on each one to serve as a terminal.
"You're an expert at carpenter work, Doughnuts," said Bob. "If you feel as ambitious as usual you can cut a couple of squares out of that oak plank over in the corner. We'll need them for end pieces to this condenser."
"Oh, that will be lots of fun," said Jimmy, who had been casting longing glances toward the old sofa. "I'd a good deal rather saw some more wood than take it easy. How big shall I make them?"
"About five inches each way, I should say," answered Bob, reflectively. "That will give us room to drill holes in each corner to put the clamping bolts through. In that drawer under the table you'll find some drills. I think a three-sixteenth drill ought to be all right. There are four brass bolts in that bag on the table, and you can measure them and see what size drill you'll need. I bought them for three-sixteenth, anyway."
"You go ahead and cut out the pieces, Jimmy," said Herb. "I'll do the real hard work, like measuring the bolts and picking out the drill. Then when you get the end pieces cut out, the drill will be all ready for you to put the holes through."
Jimmy gave him a withering glance, but rolled up his sleeves and set to work. Once started he made the sawdust fly, and before very long had two stout looking pieces of solid oak cut out.
"Where's your drill, Herb?" he inquired then. "Don't tell me you haven't got that ready yet!"
"All ready and waiting," was the reply, and Herb handed over the required tool. "Go to it, and see that you make a first class job of it."
Clamping both pieces of wood in the vise, Jimmy ran the sharp hand drill through in a workmanlike manner, and then viewed his work with pardonable pride.
"There you are," he said. "If this condenser doesn't condense, it won't be because it hasn't got two good end pieces, anyway."
