This is like a huge radial arm or chop saw. We use it to cross cut sheets of plywood. The saw is a standard circular saw mounted on tracks

The tracks are mounted on our homemade frame. Along the bottom, you can see a lip to hold the plywood in place.

Here’s a stage weight. It counters the weight of the saw. Thus, making it easy to lift the saw back to it’s home position.The tracks and saw holder comes in a kit. The kit runs around $200. We purchased the MDF and used scraps for the misc. parts.
