What is Silent Gear Metalworks?

Same as in the All the Mods 10 2.47 guide

Silent Gear Metalworks is in this pack as version 1.21.1-1.2.1. It's installed from the start, so you don't need to add anything to try it out.[1]

Unverified No mod description, guidebook or other documentation was available when this guide was written. That means we can't yet confirm what Silent Gear Metalworks adds, who it's aimed at, or where it fits in the pack's progression. Treat any claims you see elsewhere about its features as unconfirmed for this pack.

How do you get started with Silent Gear Metalworks?

4 parts

The mod's own tooltip says that all metal and gem tool parts need to be cast in a foundry from Productive Metalworks. So your first goal is to get casts made and molten metal flowing, and only then move on to the bigger alloys.[2]

First, make your casts

Start with the casts. In this pack each one is made by casting a Silent Gear part with molten steel. The pack changed these recipes, so don't rely on the mod defaults. For example, the Axe Cast comes from an axe head. The same pattern gives you the Bow Cast, Dagger Cast, Excavator Cast, Chestplate Cast and the rest, each using the matching Silent Gear part.[3]

Axe CastChanged by the pack

Item Casting (productivemetalworks)

Recipe id: sgearmetalworks:casting/axe_cast

Every cast follows this pattern with its own Silent Gear part.

Next, melt your base metals

Next, get molten metal. This pack has melting recipes for Molten Azure Silver and Molten Crimson Iron. Both can be melted from ores, raw materials, ingots, nuggets, dusts and storage blocks. The pack changed these recipes, so don't assume the mod defaults.[3]

90× Molten Azure SilverChanged by the pack

Item Melting (productivemetalworks)

  • any azure silver ingot

Recipe id: productivemetalworks:melting/ingots/azure_silver

Melting an azure silver ingot gives molten azure silver.

90× Molten Crimson IronChanged by the pack

Item Melting (productivemetalworks)

  • any crimson iron ingot

Recipe id: productivemetalworks:melting/ingots/crimson_iron

Melting a crimson iron ingot gives molten crimson iron.

Then climb the alloy chain

The mod's alloys are made by fluid alloying, and the pack changed all of these recipes. Molten Azure Electrum uses molten azure silver, and Molten Crimson Steel uses molten crimson iron. Molten Blaze Gold is a separate, simpler alloy. Molten Tyrian Steel then needs both azure electrum and crimson steel. The last step, Molten Uru Metal, needs tyrian steel and azure electrum, so work through them in that order.[3]

90× Molten Azure ElectrumChanged by the pack

Fluid Alloying (productivemetalworks)

  • 360× any molten azure silver
  • 100× any molten ender
  • 180× any molten gold

Recipe id: productivemetalworks:alloying/molten_azure_electrum

Azure electrum is an early alloy and feeds the later ones.

270× Molten Crimson SteelChanged by the pack

Fluid Alloying (productivemetalworks)

  • 200× any molten blaze
  • 810× any molten crimson iron
  • 100× any molten magma cream

  • 90× any molten tyrian steel

Recipe id: productivemetalworks:alloying/molten_uru_metal

The end of the chain.

Finally, cast Uru metal

Once you have molten Uru metal, you can cast it into an Uru Metal Ingot, an Uru Metal Nugget or an Uru Metal Block. The pack changed these casting recipes. The ingot and nugget each need their matching cast from Productive Metalworks, while the block is cast without one.[3]

Uru Metal IngotChanged by the pack

Item Casting (productivemetalworks)

Recipe id: productivemetalworks:casting/ingots/sgearmetalworks/uru_metal

Casting molten Uru metal into an ingot.

You can also convert between nuggets, ingots and blocks in a crafting grid, and melt them back down. The Uru metal melting recipes are unchanged mod recipes.[3]

How does Silent Gear Metalworks work?

5 parts

Same as in the FTB Skies 2 1.22.0 guide

Silent Gear Metalworks doesn't bring machines of its own, at least none that show up in the sources. It plugs Silent Gear into the foundry from Productive Metalworks, and everything below runs through that foundry's recipe types: melting, casting and alloying.[2][4]

Tip: The mod's own blueprint tooltip says it plainly: all metal and gem tool parts require casting in a foundry from Productive Metalworks.[2]

Molten fluids

The mod adds a molten fluid, with a bucket for it, for a long list of metals and gems. These include Molten Uru Metal, Molten Crimson Steel, Molten Tyrian Steel, Molten Ruby, Molten Sapphire and Molten White Diamond. Fluid is what you move around and cast from, so this is where your item and fluid handling starts.[2]

Many recipes accept "any" fluid from a shared tag, for example any molten Uru metal or any molten steel, rather than one specific fluid.[4]

Melting

Melting turns items into fluid. In this pack, the azure electrum, azure silver and blaze gold dusts each melt into 90 units of their molten metal. The pack changed these recipes.[4]

There are also melting recipes named after the Productive Bees Uru metal comb and comb block. They give 10 and 40 units of Molten Uru Metal. The pack changed these too.[4]

Counted across the pack, 34 melting recipes of this kind produce items from this mod, with 7 different results.[4]

Alloying

Alloying combines several fluids into one. The pack changed all three alloys this mod adds: Molten Azure Electrum, Molten Blaze Gold and Molten Crimson Steel. These are the pack's exact recipes:[4]

90× Molten Azure ElectrumChanged by the pack

Fluid Alloying (productivemetalworks)

  • 360× any molten azure silver
  • 100× any molten ender
  • 180× any molten gold

Recipe id: productivemetalworks:alloying/molten_azure_electrum

90× Molten Blaze GoldChanged by the pack

  • 200× any molten blaze
  • 810× any molten crimson iron
  • 100× any molten magma cream

Recipe id: productivemetalworks:alloying/molten_crimson_steel

Casting Uru metal

Casting turns fluid back into items. For Uru metal, the amounts are 90 units for an Uru Metal Ingot and 10 for an Uru Metal Nugget. A full Uru Metal Block takes 810 units. The pack changed all three recipes. The ingot and nugget recipes use an ingot cast and a nugget cast from Productive Metalworks, and the block is a block casting recipe.[4]

Uru Metal IngotChanged by the pack

Block Casting (productivemetalworks)

  • 810× any molten uru metal

Recipe id: productivemetalworks:casting/storage_blocks/sgearmetalworks/uru_metal

If you'd rather skip the foundry for storage, ingots and blocks also convert by hand in a shapeless crafting recipe, in both directions.[4]

9× Uru Metal IngotMod recipe

Crafting Shapeless

Recipe id: productivemetalworks:crafting/uru_metal_ingot_from_block

The mod's own Uru part recipes use different fluid amounts depending on the part: 90 units for arrow heads, 270 for an axe head and 360 for boot plates. These are unchanged mod recipes.[4]

Casts

The mod adds a cast item for each Silent Gear part type, such as Arrow Cast, Axe Cast and Boots Cast. There are also casts for bows, swords, rings, shields and many more tools and accessories.[2]

In this pack, those three casts are made by casting a Silent Gear part, using 360 units of any molten steel. The pack changed all three recipes.[4]

In total, 34 item casting recipes take Silent Gear items and fluids and make items from this mod. A further 33 casting recipes make both this mod's items and Silent Gear items.[4]

How do you progress through Silent Gear Metalworks?

5 parts

The metals from this mod form a chain. You begin with basic molten metals, combine them into alloys, and finish with Uru Metal. Every step works with fluids, so you melt, alloy and cast.[3]

Base molten metals

Molten Azure Silver and Molten Crimson Iron are your entry points. In this pack you can melt each of them from its ore, raw material, raw block, ingot, nugget, dust or storage block. Those melting recipes are all marked as changed by the pack, so the pack's values apply, not the mod defaults.[3]

First alloys

Next come the alloys built from those base metals, and their alloying recipes are all changed by the pack. Molten Blaze Gold combines molten blaze with molten gold. Molten Azure Electrum takes molten azure silver, molten ender and molten gold. Molten Crimson Steel takes molten blaze, molten crimson iron and molten magma cream.[3]

90× Molten Blaze GoldChanged by the pack

Fluid Alloying (productivemetalworks)

  • 200× any molten blaze

  • 810× any molten crimson iron
  • 100× any molten magma cream

Recipe id: productivemetalworks:alloying/molten_crimson_steel

Tyrian Steel

Molten Tyrian Steel is the first recipe that needs both the Azure Electrum line and the Crimson Steel line. On top of those it takes molten ancient debris and molten shulker shell. Finish both alloy lines before you start here. The recipe is changed by the pack.[3]

360× Molten Tyrian SteelChanged by the pack

Fluid Alloying (productivemetalworks)

  • 100× any molten ancient debri
  • 90× any molten azure electrum
  • 90× any molten crimson steel
  • 100× any molten shulker shell

Recipe id: productivemetalworks:alloying/molten_tyrian_steel

Uru Metal

Molten Uru Metal sits at the end of the chain. Its alloying recipe uses molten tyrian steel, molten azure electrum, molten ancient debris, molten shulker shell and molten heavy core. It also takes a meat input, which none of the earlier alloys here do. The recipe is changed by the pack.[3]

90× Molten Uru MetalChanged by the pack

Fluid Alloying (productivemetalworks)

  • 180× any meat
  • 100× any molten ancient debri
  • 90× any molten azure electrum
  • 180× any molten heavy core
  • 100× any molten shulker shell
  • 90× any molten tyrian steel

Recipe id: productivemetalworks:alloying/molten_uru_metal

You cast the molten metal into an Uru Metal Ingot, an Uru Metal Nugget or an Uru Metal Block. The casting recipes are changed by the pack. Melting Uru Metal items back into fluid uses the mod's own recipes, unchanged by the pack. You can also convert between ingot, nugget and block with plain crafting.[3]

Uru Metal IngotChanged by the pack

Item Casting (productivemetalworks)

Recipe id: productivemetalworks:casting/ingots/sgearmetalworks/uru_metal

Casting an ingot uses an Ingot Cast and molten Uru Metal.

Casts for Silent Gear parts

The mod also adds casts for Silent Gear parts, such as the Pickaxe Cast, Helmet Cast and Bow Cast. In this pack these cast recipes are changed and use molten steel together with the matching Silent Gear part, so you can start on them once you have a steel supply.[3]

Pickaxe CastChanged by the pack

Item Casting (productivemetalworks)

Recipe id: sgearmetalworks:casting/pickaxe_cast

The other casts shown in the pack follow the same pattern with their own Silent Gear part.

How does Silent Gear Metalworks work with other mods?

2 parts

Silent Gear Metalworks links Silent Gear with Productive Metalworks. The in-pack recipes that use items from both mods cover casts for Silent Gear gear parts and an Uru Metal line of items.[3]

Gear part casts

Silent Gear parts get matching casts from this mod. For example, the Sword Blade is used to make the Sword Cast. The same pattern shows up for the Pickaxe Cast, the Helmet Cast and the Ring Cast. These recipes use Productive Metalworks' item casting recipe type, and the pack has changed them from the mod's defaults.[3]

Sword CastChanged by the pack

Item Casting (productivemetalworks)

Recipe id: sgearmetalworks:casting/sword_cast

Making a cast from a Silent Gear part. The pack changed this recipe.

Recipes also go the other way, from a cast back to its Silent Gear part. They use the mod's own gear casting recipe type, and the pack changed these as well. For example, the Tool Rod Cast leads to the Tool Rod, and the Tip Cast leads to the Tip Upgrade.[3]

Sword BladeChanged by the pack

Sg Gear Casting (sgearmetalworks)

Recipe id: sgearmetalworks:casting/silentgear/sword_blade

Turning a cast back into the Silent Gear part. The pack changed this recipe.

Uru Metal

Productive Metalworks casting also turns molten Uru Metal into items. The Ingot Cast makes the Uru Metal Ingot, and the Nugget Cast makes the Uru Metal Nugget. The pack changed both of these recipes.[3]

Uru Metal IngotChanged by the pack

Item Casting (productivemetalworks)

Recipe id: productivemetalworks:casting/ingots/sgearmetalworks/uru_metal
