I pretty much followed the plans exactly as provided. The folding brackets I used are supposed to be heavy duty and able to handle up to 100 lbs. per pair of brackets. We'll see how they do. If needed, I might add the 2x2 or 2x4 braces I've seen many others do on here. It's nice to finally have my mitre saw off of my workbench.
These are the brackets and wheels I used.
