"We've got a job of checking dimensions."
"Nothing more? Do you need the metal for electrical reasons?"
"No," said Don. "What have you in mind?"
"Our toolshop is nicely equipped to grind glass gauges. We can do that better than making Jo-blocks. Can you use glass ones?"
"Hang on a minute." Channing turned to Walt. "Kingman says his outfit uses glass gauges. Any reason why we can't?"
"See no reason why not. I've heard of using glass gauges, and they've got some good reasons, too. Tell him to go ahead."
"Kingman? How soon can we get glass ones?"
"Horman, how soon on the glass blocks?"
"Two dozen? About a week."
"We'll have your blocks on the way within four days, Channing. Four days minimum, plus whatever wait is necessary to get 'em aboard a spacer."
