Anything worth thinking about is worth overthinking, right? So I made a setup to precisely measure (within the bounds of what's possible in Scrap Mechanic) various sawmilling setups. The findings are as follows: 1. It doesn't matter what kind of motor (or controller) you use to cut logs, they'll all work as long as they spin fast enough. (For controllers, it's pretty much the max of a level 5 controller) 2. All motors cut logs just as quickly (again, as long as they're spinning fast enough). 3. There's a strange mechanic where if you have a sawblade on a loose bearing and you push it into a log, sometimes it will start to spin, and sometimes it spins fast enough to cut the log! 4. Logs have hit points. Every tick a spinning saw is in contact with a log it chews off some of those hit points. A single sawblade takes a little more than a second to chew through the hit points of a log (and break it down to its next level). 5. Because of the above, if you have 4 saws cutting the log all at once, they'll cut 4 times as fast as 1 would. 6. If you just glue two sawblades together, they still only count as one sawblade. If you separate the sawblades with a bearing, then they both count. That's true even if the two sawblades aren't spinning with respect to each other. 7. If a blade is in contact with multiple logs, it cuts all those logs. The setup is capable of more precision than the "about a second" I mention above and use in the video. But honestly I think you're a little overnerdy if you try and get it down to the decimal points. Still, if you're curious: When used with the timer circuit, the blade turns: 49 degrees in .5 seconds 95 degrees in 1 second 132 degrees in 1.5 seconds 184 degrees in 2 seconds Cutting: 1 blade: 103 degrees 2 blades: 57 degrees 3 blades: 44.5 degrees 4 blades: 35.5 degrees Bear in mind there are 40 ticks in a second, and the logic gates all impose a single tick delay. That tickiness also explains why the numbers with the simple timer circuit are a bit pixelated.
