Craft Andesite Casings from Biomes O' Plenty Wood
Gather and Prepare Your Wood
Head to any Biomes O' Plenty biome and locate trees with wood types you haven't seen in vanilla Minecraft. Chop down the logs and collect several stacks—you'll need plenty for a full factory setup.
Use an axe on each log to strip away the bark. Stripped logs are required for casing recipes; regular logs won't work. You can strip wood blocks the same way.
Craft Your Casings
Bring your stripped logs or stripped wood to a crafting table. Combine the stripped wood with Andesite Alloy (crafted from Iron Ingots, Copper Ingots, and Andesite Dust) to create Andesite Casings.
The exact recipe layout follows standard Create conventions—check your recipe book or JEI for the precise arrangement. You can use any stripped wood type from Biomes O' Plenty; the mod supports all of them equally.
Scale Up Production
For large builds, consider setting up an automated wood farm in a Biomes O' Plenty biome. Use Create's mechanical tools to strip logs in bulk, then feed them into a crafting setup with Andesite Alloy to mass-produce casings.
