Using a Mechanical Saw to Cut Wood Automatically

The Mechanical Saw, a cornerstone of automation within the Create mod for Minecraft, offers an incredibly efficient solution for harvesting wood. This guide will delve into its mechanics, providing a comprehensive walkthrough for constructing an automated tree farm, and offering essential tips to optimize your setup while avoiding common pitfalls.

Understanding Mechanical Saw Mechanics

At its core, the Mechanical Saw is a versatile block designed for both resource harvesting and item processing. Its primary function for automation, particularly for wood, relies on its ability to chop blocks when placed correctly and powered by rotational force.

• Rotational Power: Mechanical Saws require a source of rotational power to operate. This power can be supplied by various Create mod components, such as water wheels, windmills, or gearboxes connected to a rotational network. The speed of this rotation directly impacts the saw’s performance, affecting both its chopping speed and the damage it inflicts on entities.
• Horizontal Chopping: For the purpose of harvesting trees and similar blocks, a Mechanical Saw must be placed with its blade facing horizontally. In this orientation, it will automatically chop wood blocks directly in front of it. When targeting a tree or a giant mushroom, the saw is designed to destroy the entire structure by breaking only its bottom-most block, leading to an efficient and rapid harvest.
• Harvestable Blocks: The saw is not limited to just basic logs. It can directly break a wide array of wood-related blocks and other natural resources, including:
  • Logs (both regular and stripped)
  • Wood blocks
  • Leaves
  • Non-muddy mangrove roots
  • Mushroom stems
  • Cactus
  • Bamboo
  • Pumpkins
  • Melons
• Item Processing (Blade Up): While this guide focuses on wood cutting, it’s important to note that a saw placed with its blade facing upwards functions differently. In this configuration, it acts similarly to a stonecutter, processing items dropped onto it. It offers unique recipes, such as stripping logs or converting stripped logs into a greater quantity of planks, showcasing its dual utility. However, for automated tree farming, horizontal placement is paramount.
• Contraption Integration: When a Mechanical Saw is part of a moving contraption, for instance, one driven by a Mechanical Bearing, it automatically receives power from the contraption’s movement. This simplifies power distribution for mobile farming setups.

Automated Tree Farm: A Step-by-Step Process

Building an automated tree farm using the Create mod involves several key stages, from power generation to item collection. Follow these steps to construct an efficient wood-cutting operation.

1. Set up Power: The first crucial step is to establish a reliable source of rotational power. A common and straightforward method is to use a water wheel, which generates kinetic energy from flowing water. This power source will drive your entire contraption, ensuring your saws operate continuously.
2. Place Mechanical Bearing: Locate a suitable area for your farm and dig a hole to place a Mechanical Bearing. This block will serve as the central pivot point for your entire moving contraption, allowing it to rotate and cover a larger area for planting and harvesting.
3. Build Contraption Frame: Around the Mechanical Bearing, construct a robust frame for your contraption. This frame can be made using Radial Chassis for circular movement or Linear Chassis for linear movement, depending on your farm’s design. Crucially, use Super Glue to attach all components firmly to the chassis and the bearing, ensuring they move as a single unit.
4. Attach Mechanical Saws: Carefully place Mechanical Saws onto the contraption frame. It is absolutely vital that their blades face horizontally towards the area where trees will grow. This orientation ensures they function as choppers, not item processors. Position them strategically to cover the maximum possible tree-growing area as the contraption rotates or moves.
5. Add Deployers: On the opposite side or adjacent to your saws, position Deployers. These should be configured to face downwards. Their role is to plant saplings automatically into the ground once a tree has been harvested, ensuring continuous reforestation.
6. Implement Item Collection: To collect the harvested wood and other drops, you’ll need an efficient item collection system. This typically involves using Portable Storage Interfaces (PSI). Place one PSI on your moving contraption, connected to an internal storage unit like a barrel or chest. Place a stationary PSI nearby, aligned to periodically connect with the contraption’s PSI as it moves. When these interfaces align, items from the contraption’s storage will automatically transfer to your stationary collection system.
7. Set up Filters: Filtering is essential for the smooth operation of your farm.
   • For Deployers: Configure them by placing saplings in their filter slots. This ensures they only attempt to plant saplings and do not waste efforts on other items.
   • For Collection: Utilize funnels, such as Brass Funnels, equipped with item filters. These filters are critical for preventing saplings from being removed from the farm’s internal storage. Configure them to allow only desired harvested items like logs, sticks, and apples to pass through to your main collection, leaving saplings behind for replanting.
8. Load Saplings: Before activating your farm, ensure a sufficient supply of saplings is loaded into the barrel or chest on the contraption. This storage unit should be connected to the Deployers, providing them with the necessary items for replanting.
9. Activate Contraption: Once all components are in place, powered, and configured, right-click the Mechanical Bearing with an empty hand. This action will initiate the contraption’s rotation or movement, bringing your automated tree farm to life.

Important Tips for Optimization

To maximize the efficiency and reliability of your automated tree farm, consider these important tips:

• 2×2 Trees: When dealing with 2×2 trees, such as dark oak, Mechanical Saws might occasionally fail to harvest the entire tree, leaving some parts standing. To mitigate this, consider removing the block immediately above the base block being cut. This often helps the saw register and break the entire tree structure.
• Efficiency and Growth: The overall efficiency of your farm is heavily influenced by how quickly trees grow and are subsequently harvested. Design your farm layout to provide ample space for trees to grow without obstruction. For even faster growth cycles, especially in modded environments, consider incorporating modded fertilizers to accelerate the saplings’ maturation.
• Item Filtering is Key: Always prioritize the use of item filters with funnels, chutes, or Portable Storage Interfaces. Proper filtering prevents critical items like saplings from being accidentally collected, ensuring they remain within the farm’s system for continuous replanting. This is fundamental to a self-sustaining farm.
• Contraption Design with Super Glue: Super Glue is an indispensable tool when building moving contraptions. It ensures that all individual components are securely attached to the moving chassis or bearing, preventing parts from detaching or being left behind as the contraption operates. Always double-check that all desired blocks are glued.
• Specialized Saws: For players looking to further enhance their automation, the “Create Saw” addon introduces various new saw variants. These specialized saws might offer increased speed, enhanced strength, or specific functionalities tailored for different wood types. Exploring these addons can significantly boost your farm’s throughput and adaptability.

Common Mistakes to Avoid

Even experienced players can make mistakes. Being aware of these common pitfalls will save you time and resources when setting up your automated wood farm.

• Incorrect Saw Orientation: This is perhaps the most frequent error. If a Mechanical Saw is placed with its blade facing upwards, it will not chop trees. Instead, it will function as an item processor, attempting to craft items dropped onto it. For tree harvesting, ensure all saws are placed horizontally.
• Unfiltered Saws (for Item Processing): While not directly related to tree chopping, if you do decide to use a saw for item processing (blade up), avoid using it unfiltered. An unfiltered saw will randomly cycle through all available recipes for items dropped on it, potentially wasting resources or producing unintended outputs. Always use an item filter to specify the desired output product.
• Sapling Depletion: A common cause of farm failure is the depletion of saplings. Without proper filtering that keeps saplings within the contraption’s internal storage for replanting, or without a mechanism for continuous sapling replenishment, your farm will eventually run out of saplings and cease to function. Always ensure a steady supply and robust filtering.
• Contraption Ticking Errors/Lag: Overly complex contraptions, especially those with many moving parts or intricate interactions, can sometimes lead to “ticking errors” or significant game lag. This can be exacerbated by mod incompatibilities. Test your designs in stages and simplify where possible to avoid these performance issues.
• Item Extraction Issues: Ensure that your item extraction mechanisms, whether they are chutes, funnels, or mechanical arms, are correctly configured and filtered. Improperly set up extractors might fail to pull items from the saw or contraption storage, leading to blockages and halting your production. Verify that all extraction points are clear and correctly filtered to move harvested goods to their destination.
