Here's a couple pictures of one I built a few years ago. It isn't fancy, but the total cost was less than $500.00. Most of it was for the 25 ton hydraulic cylinder. It's attached to the bucket boom, and powered by the hydraulic pump on the loader. It can work in both the vertical and horizontal positions. The pipes on either end are legs to stabilize it when splitting large logs in the horizontal position. When extended downward the pipes have 8" square pads that contact the ground.
