Methods of semi-precise breaking of a cinder block in half lengthwise?
Do you already have the cinderblock? If not, consider buying block that more closely aligns with your project. There are many styles and shapes of block available. If you already have the block, your best bet is going to be a concrete saw. You can rent one from a local rental agency like A-1. This is NOT a tool for the faint hearted. It’s noisy, heavy, and loud. You will need eye and ear protection, and should wear gloves, long pants, and preferably steel toed boots. The concrete saw will make short work of a stack of blocks.
