Medieval business deals were always complicated, especially when Count Lambert was in something like his current mood. Actually, I didn't care who owned what, so long as the job got done. As to the division of the profits, well, I'd have to keep my liege lord happy in any event. After that, the accountants all worked for me so he would be rewarded as I saw fit!
"Done, Baron Conrad! This has been a good day's work! I feel right about it. But I still think that when the Mongols arrive, we should be dressed in our best, so do get to work on that zipper machine, won't you? At your own expense, of course."
With that, he got up and walked away and I started thinking about how one would go about building a zipper-making machine.
Interlude One
I hit the STOP button.
"Tom, something's been bothering me since you mentioned it a few days ago."
"And what is troubling you, my son?"
"Well, you said that you found out about Conrad's trip to the Middle Ages when you went to the Battle of Chmielnick during the Mongol invasion. You said that the battle you saw had a different outcome than what's written up in the history books. And you said that the investigation teams you sent out came back duplicated. Why weren't you duplicated as well?"
"Well, I was! It was strange, meeting myself. Not because running into yourself is all that odd. With time travel, we do that all the time. But protocol is that the senior self always talks first, and the two of us just stood there, each waiting for the other to speak first, since neither of us remembered being there before. It was quite a while before I asked him why he didn't say something. Eventually, we figured out what happened. Being a sensible person, both of me, I decided to timeshare the management of the place with my other half. We flipped a coin and I got it for this century and he gets it for the next."
"Good Lord!"
"Well, what else could I do? Fight myself? I suppose it would have been more complicated had I been married, but after a bit of youthful insanity, like Conrad, I'm not the marrying kind."
He hit the START button.
Chapter Three
FROM THE DIARY OF CONRAD STARGARD
Part of my deal with Count Lambert was that I would spend two days a month looking over the projects we had going at Okoitz, so I couldn't go back to Three Walls immediately. I checked the windmills and went down the coal mine. I looked over the progress made on Count Lambert's new castle, which was now more than half built, and spent more time than was necessary in the cloth factory, mostly because all the girls working there wanted to talk to me about something or another. Mostly, they were just trying to get me interested in themselves, and since I was still pretty seriously involved with Cilicia, they were out of luck. None the less, it's fun being pursued by scantily clad young ladies, even when you don't intend being caught, so I ended up spending half of both days there. Cilicia spent her time teaching dancing to the ladies of the town, charging all the traffic could bear.
Then it was back to Three Walls, where I got a half dozen research teams going on the new projects. My usual approach to research was to set up a team of two young men, apprentices, generally, along with one older craftsman. The rule was that they had to try out everybody's ideas, and the older man was not allowed to squelch the dumb ideas that the kids came up with. I reviewed the progress with each team every week or two and threw in my own thoughts, and usually something workable resulted. On really important things, I'd set up two competing teams and let them work independently. The reward for all this, besides their pay, was in the form of cash bonuses if they were successful and the fact that if the new product went into production, the men on the research team were the obvious people to manage the new factory, so promotions were in order.
The railroads and the steamboats were just a matter of design and build, with little real research required at first. Sir Piotr's first survey job was for the railroad track.
Yashoo was sent with a crew to the new lands, which we called East Gate, to build a boat-assembly building and the foundry got busy making cast-iron railroad track. The construction crews were scheduled to go through the Warrior's school in the winter, when there wasn't much else for them to do anyhow.
We didn't have the machinery necessary to roll steel track, and with the comparatively light loads that our track would be handling, malleable cast iron was good enough. Cast iron also had the advantage of being not worth stealing. A blacksmith couldn't make anything out of it. If he tried heating it and beating on it with a hammer, it just crumbled. This fact, coupled with Anna's outstanding ability to sniff out thieves, reduced our theft problem to almost zero.
I was almost tempted to try to build a telegraph again, but not quite. There was no way that I could make copper not worth stealing, and the Mongols would probably be smart enough to cut our lines once the invasion started, so its military advantage would be nil.
Our roiling stock consisted of small flatcars big enough to carry a single container, with a load limit of ten tons. A tenth the size of modem cars, they were huge by the standards of the thirteenth century. They would all be horse or mule drawn, since our line would be only thirty miles long. There wasn't any need for greater speed and the mules already existed. Locomotives were for the future.
Sketching up the boats and the railroad took less than a week, since I had a staff of draftsmen (and draftswomen) now. The aircraft engine was something else.
My first thought had been to make an air-cooled single cylinder two-cycle engine, the sort that is used on lawnmowers, but I got to worrying about balancing it. Static balancing would be no great problem, but dynamic balancing without any sort of test equipment seemed impossible. The thought of vibrations tearing one of our frail wood-and-canvas planes to shreds in midair bothered me.
I went to a two-opposed cylinder design, where both pistons went out at the same time. If every part was identical to its opposite part, it all should balance perfectly. I hoped.
Lubrication? All we had was various animal fats and imported olive oil. I designed a pressurized lube system, knowing that it would be contaminated with the wood alcohol I hoped to use. After that, we would just have to try different mixtures and bum out engines until we found something that worked reasonably well.
Carburetion? All I could do was to sketch up what I think I saw in a textbook fifteen years ago and hope.
Ignition? I put one research team to work on a magneto system and another on the battery-and-coil type and again I hoped.
Then there were the mechanical parts. The engine had to be as light as possible, which meant that I needed the best possible strength-to-weight ratio. Sad to say, our best cast steel was weaker than ordinary cast bronze. Bronze was expensive, since it was made, in part, of tin that had to be imported from England, but hang the expense. I'd get it out of Count Lambert somehow. Everything on that engine was bronze except for the bearings (another research group), the cylinder liners, and the piston rings. These last two were cast iron, just like on many modem engines.
As more and more problems were encountered, more research teams were set up. Did we have a ceramic that had a coefficient of expansion similar to some metal we already had, so we could make a spark plug that didn't shatter when the engine heated up? Get the machinists to make spark plug jackets out of as many metals as they had , and for each type, have the potters mold in all their different types of clays and try to fire them. Could we insulate wires with some sort of varnish? Put a team of alchemists on it!
