“I guess that's what you want, but I haven't finished the Lewis yet. Reckoned I'd wait until I could get a bit of horseshoe iron for the wedge when the new stores come along.”
“What's that bar in the corner?” Charnock asked.
“Steel,” said the smith. “A bit off the end would make a wedge, but you want to be careful you don't overheat the steel in the forge if it's to stand hammering after. Horseshoe iron's better for your particular job. Come back in a day or two and I'll have the thing ready.”
Charnock left him and one afternoon soon afterwards helped Festing to notch and bore the heavy cross-tie to fit the post and the ends of the timbers it was to hold in place. These were intended to strengthen the frame, of which the post and tie were the most important members, and Festing had waited until their other ends were securely fixed. When the light was fading he beckoned Charnock.
“You might get the Lewis bolt. The smith sent word it's ready and I want to fasten the tie before we stop.”
When Charnock reached the forge the smith was absent, but he blew the fire until the light flickered about the shop and looked for the bolt. He found it in a corner and took the wedge to the hearth. It was properly shaped and slotted for a cross-bolt, but it looked rough and scaly, and giving the blower a few more strokes he tapped it once or twice. The scale fell off and the metal looked sound. Then while the flame spread about the fuel he glanced round the shop. There was no horseshoe iron, but the bar of steel had recently been cut, and he thought the wedge had been forged out of its end.
Charnock did not think this mattered much. Festing had urged the smith to finish the job, and the man knew his business. Since he had been forced to use steel, he had no doubt taken the necessary precautions. It was dark when Charnock got back to the frame, but a blast-lamp threw out a dazzling glare and he climbed to a beam on which Festing sat. At the timber's inner end a fire burned on a shelf of rock and a man was stirring something in an iron pot.
“We're melting lead to fill up the hole, though I don't know if it's necessary,” Festing said. “Have you got the bolt?”
“It's here. He has made it out of steel; the iron he expected hasn't arrived.”
“That's all right. They now use steel for many jobs instead of iron, and the softer kinds are quite as tough. Anyhow, we can trust the smith not to burn the metal. Help Black while I get the tie ready for fastening.”
