Well, with that bump on his head, Laney would probably leave him alone for the rest of the day, anyway. Time to quit malingering. He stood up from the chair he’d been sitting on, cradling his wounded hand. The throbbing had nearly passed. Neat stuff, that pasty goo, he reflected. Not waiting to be released by the nurse, he ducked out of the aid station and headed back for the powerhouse.
He trudged through the muck of the recent rain and avoided the heavy carts pulled by bawling brontosarries until he saw the smoke rising from “his” boiler. Several ’Cats tended the beast, and it shimmered with heat and suppressed energy. The engine it powered was one of the first they’d built, and it wheezed and blew steam from its eroded and imperfectly packed pistons. He hated the engine and wanted another one, but he had to respect it as well. It had been a prototype, crudely built and not expected to last, but here it was, still chugging away after, well, thousands of hours. The generator it turned was also one of their first and he was proud of it. He’d designed it himself, and it was doing fine. Laney’s shop had actually made the transmission gears that boosted the RPMs of the slow-turning engine to spin the generator fast enough to provide the calculated voltage, but Laney probably didn’t do it himself.
“Silly, useless bastard,” he muttered, and opened the fabric flap that covered the entrance to his domain.
“How you hand?” asked one of his new strikers solicitously. Rodriguez didn’t remember the ’Cat’s name. It was unpronounceable and he hadn’t earned a nickname yet, but he’d been one of the deserters he’d succeeded in keeping. The kid was working on one of their simplest products: thermocouples for the vast variety of temperature gauges everybody was screaming for. Essentially all he had to do was join a piece of copper to a piece of iron. When heat was applied to the joint, current was produced. The higher the heat, the more current. The reason he got to keep this ’Cat was that when he was trying to explain intangible, invisible free electrons, the little guy actually seemed to understand. He had high hopes for him.
Lemurians in general were almost naturally mechanically inclined and great with practical geometry. They were accomplished jokesters and pranksters and could conceptualize common hypothetical outcomes. They loved gizmos, and if they could see something, they could understand it without much trouble. They were very literal- minded, though. When it came to things they couldn’t see-like electricity-or even hypothetical outcomes they had no experience with, they had more trouble. He’d been forced to set up a few grade-school demonstrations to let them see electricity before he could convince them it was real. He also let them feel a little now and then, but had to caution them very carefully about feeling too much of it! He still wasn’t sure how much most of his ’Cat electrician’s mates and strikers really grasped, but they knew they had to make gizmos to create and harness the semimythical electricity, and they were good about scrupulously following safety regulations. The fact that he’d threatened to give them to Laney if they goofed around with the juice probably helped in that regard.
He waved his bandaged hand at the ’Cat with the unpronounceable name and moved along. He wanted to check on the progress of the portable DC generators they’d been working on when he hurt himself. He was surprised to find Steve Riggs waiting for him at the benches they’d set aside to assemble the things.
“Mr. Riggs! Good to see you, sir.”
Steve laughed. “You mean it’s good to see me without Laney for a change. Otherwise, you’re probably wondering what I’m doing here, getting in the way.”
“Well, yes, sir.”
“How’s the hand?”
Rodriguez raised his hand and flexed the fingers in the bandage. “Fine.”
“Good. Look, I really don’t mean to pester you, but these transmitters we’re putting together are pretty simple affairs. They don’t have tubes and their voltage requirements are somewhat critical. I just wanted to see for myself how you’re coming along.”
“Fair enough.” Rodriguez motioned him to a bench where several ’Cats were cleaning up a stack of short, pipe-shaped objects. “Those are the frames. They came out of Laney’s shop and they’re rough as hell. I have to have the guys file the burrs-with shitty files out of Laney’s shop…”
“I get the picture. Laney’s a piece of work. Skip it.”
“Aye-aye, sir. Anyway, those are the frames. These guys over here are wrapping the field coils.” He stopped, self-consciously. “That’s how I cut myself. It’s great the ’Cats can make wire; I just wish it was a little more, you know, round.”
“We’ll get to that someday,” Riggs said patiently. “For now, just be thankful. We’re starting to get a lot of wire out of Amagi, but we need it for other stuff.”
“Yes, sir. Anyway, there’s the pole shoes. We screw ’em to the frame on the inside and it holds the coils in place.”
Riggs gestured at a bin with a number of internal assemblies. “Those armatures look like they came out of the Delco factory.”
“Thank you, sir. They’re a bitch. First we have to turn the shafts on the one little lathe we have…”
“It is one of the ship’s lathes.”
“Yes, sir, thank you, sir. It would be nice if we could get the guys in the ordnance shop to make those, though. Them and the core. We can’t make those like they do at Delco. We have to mill the slots on the rotary table. It’s still not a huge job, but we’re going to need more capacity. We have to make the big generators one at a time, mostly using crap from Laney, and we can’t work on those at all while we’re doing this.”
“The guys at ordnance have their hands full. I’ll see if I can get you one of the new, bigger lathes, and maybe a bigger mill. You’ll have to make motors for them, though. This isn’t a belt-drive shop, and it isn’t going to be.”
“I understand. Motors we can do.”
“So, what are you insulating the coils with?”
“Fiber. Just like the real thing, only we mulch up some of Mr. Letts’s gasket material and mix it with some other stuff. Mikey’s in charge of that.”
“How does it hold up? What about heat?”
“So far, so good. We haven’t had the glue-up issues Ben has, for example, and it does insulate well. It’s kind of like putty. We cram some in on top of the coils in the core slot too. Anyway, the coils are soldered to the commutator bar.”
Riggs inspected one of the brush end frames that a ’Cat was finishing up. “You wave-wound the core, but you’re only using two brushes?”
“Yes, sir. We’ve still got a hell of a spring shortage. We’re actually using the same gear springs Ordnance is making for their musket locks! Wave-wound generators will work with two brushes or four. We might want to put four in later.”
Riggs pulled the short whiskers on his chin. “Musket springs!” He snorted. “How do the brushes hold up?”
“The springs are fairly stout and they don’t have much range of motion. The brushes’ll have to be replaced every hundred hours or so, I’m afraid. Since we have to use brass bushings, they’ll have to be kept lubed and replaced pretty often too.”
Riggs nodded. “Okay, I want a dozen extra brushes, two extra musket springs, and half a dozen bushing sets for each completed generator. What are you doing to regulate the voltage?”
“Well, sir, since you want these things to be wind powered, we’ve calculated a low cut-in speed and a high charging rate at those lower speeds. If a serious blow hits, it’ll need to be disconnected. If they spin up too fast, centrifugal force will throw the windings out of their slots and thrash the whole thing. To cap the voltage, well, we’ve got to use a voltage regulator.” Rodriguez pointed at yet another group of ’Cats working at a separate bench. “They’re making vibrating regulators. I don’t think they have a clue what they’re doing, but I calculated all the values and gave them the plans. They could all be watchmakers after the war. They won’t screw ’em up. Of course, I’ve got my ammeter to double-check each one. Managed to save that.”
Riggs smiled. “Very good. Very, very good. If you weren’t already in charge, I’d put you there.”
“Uh, thanks.”
“Now, one more thing; just a little matter, really. How do you plan to refurbish the generators, motors, and other essential equipment on Walker after we raise the ship?”
“And this, dear boy, if I’m not much mistaken, is the spleen!” Courtney Bradford leaned back and fanned himself with his sombrerolike hat, as much to clear the vapors of the quickly putrefying creature as to cool himself.
