Table Saw
The Table Saw is a very straightforward machine.
You can use it to turn logs into 8 planks instead of the normal 4 you would get when using a Crafting Table.
The recipe is already found in your Slimefun Guide, but here is the final version:
You can also place an Output Chest next to the Stonecutter to catch your crafted Items. Otherwise your planks will be dropped on top of the Stonecutter.
Hold a piece of log in your hand and right-click the Stonecutter.
Note that the Table Saw supports all types of logs, including Stripped variants and barks.
