I had to get these off my workbench, they're too heavy to be moving around. I thought they would be too heavy for a flip top cart, so I'm trying this. Like most things in my small garage, it's a compromise. The planer is a wee bit low, and the sander's a little high, but close enough to get by. It's nothing fancy or pretty, but it is sturdy and low cost. It's all off the shelf 2×4's half lapped, glued, screwed and air nailed together. I will finish this off with homemade infeed/outfeed tables. I left it as an open framework for when I need to get to the planer knives. It might not work for everyone, but it is an improvement for me.
