This Create Add-on only adds two new items: Brass Cogwheels and Large Brass Cogwheels. They're made by deploying regular cogwheels with brass ingots.
This mod is configurable, in brasscogwheels-server.toml you'll be able to change stress impact values for the two new blocks. By default the stress impact is 0.0, just like regular Create cogs.
ServerEvents.recipes(e => {
e.remove({mod: "brasscogwheels"})
})
This mod was intended for modpack authors who want to balance Create, by making original Cogwheels consume more stress than these you can spend more resources for a more forgiving option for your contraptions.
