I made a 16-inch piece to hold the splitter edge. A wraparound flat iron holds the unit to the boom as it slides. I used a 3-inch presplitter wedge ahead of the blade. A wedge on each side separates the block into four equal pieces and sweeps split wood to the side. All can be operated from the seat of the backhoe.
Electrical spools make excellent workbenches for the shop.
We put four big casters on the base of our spool to make it easier to roll around the shop. I use mine to handle motors when working on cars. I can roll it under the hoist and drop the motor. All my tools are on the bottom shelf. Bin slides that are seldom used or adjusted can get very sticky.
