I’m currently working on fine-tuning my farming room. This means that showing off my lubricant production will be a little while longer. I realized that I wasn’t using Rotarycraft’s Fans to the fullest of their capacity. So instead, today, let’s talk about moving up tech tiers in Rotarycraft.

If you play Rotarycraft for any length of time, you’ll soon realize that a lot of what you really want to do with the mod is out of reach without bedrock dust and ingots. Wait. Bedrock? That unbreakable stuff around y-levels 1-5 below which is just an endless void? Yeah. Only it’s not so unbreakable, though breaking it requires a lot of power compared to what I’ve shown so far (i.e. powering fermenters, water pumps, grinders, even an extractor, for goodness’ sake).

Behold, the Bedrock Breaker: the machine that holds within it the keys to Rotarycraft’s top-tier tech and generally crazy-awesome stuff!

Rotarycraft’s Bedrock Breaker

To get this puppy to work, you’ll need 2.097 Megawatts of power. That’s 2,097,000 Watts, or the equivalent of 16 AC electric engines, 32 gasoline engines, 128 steam engines, or 2048 DC electric engines. Plus, you’ll need to make sure that the torque is 8,192 Nm, which is far, far more torque than we’ve needed to produce so far. The 16 AC electric engines will do it (512 Nm x 16 = 8.192 kNm), and making them wouldn’t be that expensive (each one costs 12 gold ingots, 4 iron ingots, and 1 redstone dust for a total of 192 gold ingots, 64 iron ingots, and 16 redstone dust).

But I think you’re better off using one of three other options: 1) 4 Hydrokinetic Engines, 2) 8 Industrial Coils, or 3) a single Microturbine. The last engine is the intended way to power the Bedrock Breaker and would be the cheapest to make, but it would require jet fuel and multiple gear boxes. I’m not yet ready to post about jet fuel (coming soon). The cost of 4 Hydrokinetics is somewhere in the middle. Each one costs 75 iron ingots for a total of 300 iron ingots, but you’ll need to pipe in lubricant to make them work. While going the Industrial Coil route is the most expensive in terms of iron (each one costs 51 iron ingots for a total of 408 iron ingots), they don’t require lubricant, jet fuel, or gearboxes, and they are more transportable (and generally useful) than Hydrokinetics. In the end, it’s really going to be a matter of preference. For this post’s purpose, however, we’re going to use Industrial Coils. So we need to talk about three things: 1) charging Industrial Coils; 2) getting the materials you need to build a Bedrock Breaker; 3) making bedrock ingots from the dust. ***Make sure to check my other two posts on powering the Bedrock Breaker with the Microturbine: with and without diamonds.***

Industrial Coils

Industrial Coils are Rotarycraft’s built in battery block. But rather than storing power in electricity, it stores shaft power within the tension of an industrial strength spring. To charge them, you simply hook them up any kind of shaft power (one side receives power when there is no redstone signal, the other emits when a redstone signal is applied). Torque and rotation speed don’t matter, just the total power (so don’t bother with gearboxes or, worse, a worm gear). Theoretically, you could hook one up to a DC electric engine and just let it go … and go and go and go, because it will take freaking forever for the power of a single DC electric engine to accumulate a significant amount of stored energy. My favorite way to charge industrial coils is by using two AC electric engines (four would be even better, having a power equal to one Hydrokinetic).

But beware: you can’t just set these things to charging and walk away without taking certain precautions. The reason is that it is possible to OVER-charge Industrial Coils, and when that happens … KABOOM! Almost all of this crater used to be solid rock before I did my little over-charging experiment.

Well, on the bright side, I have a new room.

Fortunately, Industrial Coils emit a redstone signal (through a comparator) in relation to their charge. When full, they emit an analog redstone signal of strength 15. That lets you create automatic redstone switches to shut off the power source and/or switch the Industrial Coil from input to output mode.

I am enjoying using GeoStrata blocks to gradually transform the crater into a set of cool rooms, including a new and improved Industrial Coil charging station.

An overview of my Industrial Coil charging station.

A comparator clock powered by a redstone torch (so that it can be turned off manually by the lever or automatically by another redstoen signal). This activates the AC electric engines.

The Industrial Coil emits an analog redstone signal proportional to its stored charge.

Once the redstone signal reaches the desired level (I have it set to strength 14, here, meaning 14 pieces of redstone dust between the comparator and the repeater), it activates a repeater which sends a redstone signal both to the Industrial Coil (making it stop taking a charge) and to the block holding the redstone torch that activate the comparator clock (thus, shutting down the AC electric engines). This setup is necessary when using AC electric engines, because they don’t immediately shut off when the clock goes off. That’s actually how the crater came into existence in the first place.

Acquiring the Bedrock Breaker

As of v25, the Bedrock Breaker requires two tungsten ingots. So how do you get tungsten, seeing as Rotarycraft doesn’t add any world gen? Prior to v25, you had to acquire a Silk Touch pick, get some redstone ore, and process it in an Extractor. Tungsten flakes were an occasional by-product. Thankfully (because in the years I’ve played Minecraft, I think I’ve managed to get the Silk Touch enchantment legitimately maybe twice), in v25 Reika has changed the by-products a little bit. Now, tungsten flakes are an occasional by-product of iron ore, while redstone ore produces aluminum dust as a by-product.

By the way, I haven’t mentioned much about powering an extractor. It is complicated, but if you’re willing to babysit it a little, you can power one using only a gasoline engine and a 16:1 gearbox (you’ll need at least steel). When set in torque mode, this will power the first and fourth stages, whereas when set in speed mode, it will power the second and third stages. You’ll have to do this in any case before you can use the Bedrock Breaker.

The simplest way to power a Rotarycraft Extractor: a Gasoline Engine, a 16:1 gearbox, and a Bevel Gear to direct the power upwards (the Extractor only takes power from beneath).

Once you have your tungsten flakes, you’ll need to heat a furnace to 1350 degrees Centigrade to cook them down into tungsten ingots. This is far hotter than a normal furnace, and it can only be accomplished by using another Rotarycraft machine to heat the furnace from the outside. Now, there are two kinds of heaters in Rotarycraft: the Friction Heater (which I’ve talked about before) and the Heater. The Heater sits below its target, takes shaft power from below, and uses fuel (coal, charcoal, lava buckets, etc.), but you can manually set its target temperature (something you cannot do with the Friction Heater). I think you’re supposed to be able to use a Heater on vanilla furnaces, but I haven’t had any luck with that. In any case, it’s just as easy to power a Friction Heater with the power of two merged Industrial Coils set to maximum output (1024 Nm at 1024 rad/s). If you’re outside in a non-snowy biome or reasonably deep underground, say y-level 45 or below, your Friction Heater will get up to between 1350 and 1400 degrees (outside in a desert the Friction Heater will reach 1365 degrees). This will cook tungsten flakes in your furnace into Sintered Tungsten Ingots. *** Note, once again, that the intended way to power the Friction Heater to smelt Tungsten is the Microturbine. ***

A simple way to cook Tungsten Flakes into Tungsten Ingots: two Industrial Coils set to maximum output (1024 Nm and 1024 rad/s) powering a Friction Heater. The ambient temperature needs to be at least around 23 degrees Centigrade, so outside in anything but a snowy biome or a moderate depth underground. Note the lever between the Industrial Coils to supply the redstone signals.

Once you get the furnace to 1350 degrees, the Tungsten Flakes will turn into Sintered Tungsten Ingots.


Using the Bedrock Breaker and Making Bedrock Ingots

Using 8 fully powered Industrial Coils, you should have enough power to break at least 6 pieces of bedrock, giving you 12 bedrock dust, which is enough to make 3 bedrock ingots.

Using a couple of Bevel gears, I attach the power of the Industrial Coils to the back of Bedrock Breaker. Placing a chest next to the Bedrock Breaker makes it so that the bedrock dust isn’t just ejected into the world to despawn. That stuff is precious, yo. As of v25, the Bedrock Breaker will now act like a Boring Machine in that it will dig indefinitely in a straight line, loading the chunks it needs to load as it proceeds. This is a good reason to point Bedrock Breaker horizontally rather than straight down.

8 Industrial Coils can be merged using 7 Shaft Junctions (I also have a Bevel Gear at the end, but clearly that isn’t necessary – I just liked the straight line for the redstone dust).

Bedrock dust is itself an ingredient in things like the Compactor, which turns coal into diamonds. But to make the highest tier armor and tools and stuff, you’ll need bedrock ingots. To make bedrock ingots, heat a Blast Furnace (not a vanilla Furnace) with a Heater (it definitely works with the Blast Furnace) or Friction Heater to 1000 degrees. Place four bedrock dust in one of the left slots and one HSLA steel ingot in one of the nine slots on the right. This will make one bedrock ingot. *** Note that a change is coming in the 1.7 update to the Heater that will make it explode if you try to use it over 1000 degrees. I think what this will mean is that the Friction Heater is what you’re going to need to use with the Blast Furnace to make bedrock ingots.

A simple way to heat a Blast Furnace to 1000 degrees: use a Gasoline Engine to power a Heater from beneath. The Heater requires some kind of fuel source, as well (coal or charcoal is fine).

In the Heater’s GUI you can digitally set its target temperature. To make Bedrock Ingots, I would set it to just over 1000 degrees (not 1400 as you see here, which would be better for Tungsten).

Bedrock tools and armor are awesome, come automatically enchanted, and never break. Maybe this wasn’t the smartest use of my first twelve bedrock dust, but I just had to have the bedrock pickaxe, which comes enchanted with Silk Touch and which I subsequently enchanted with Efficiency IV. So now I have crazy-fast smooth stone production, and I’ll soon have bunch of other crazy-awesome things.
