I will start by saying I am not a professional woodworker and my finished product had some flaws like the frames were a little wider than 2'x4' so the plywood top is slightly smaller than the frame. I built these using 2x8's that I cut down to 2x4s. I did not plane the wide edges but I trimmed the short edges on my table saw. Maybe this is a reason for this.
The plans were good and I followed them as is. As Zach likes to say, these are rock solid. Maybe a little too rock solid. They are heavy. My biggest issue is after building them, with the 4" wheels, they ended up being WAY too tall for me (I am 6 feet tall). I may have done something wrong, but they ended up about 41" tall which is too much for me. I reread the instructions and noticed a small note indicating all the sizing was designed for Zach who is 6'4" tall. I guess I should have caught that and adjusted. However, I would suggest the plans should be for a standard height like 36" and people can adjust if they want something taller. That way if they miss the note it is not a total loss. It is easier to add some height than to take it away. I ended up taking off the 4" wheels and replacing them with retractable caster wheels that mount to the side of the legs. This means I cannot tie them together into a 2'x8' configuration but that was an OK sacrifice for me to get tables that are now around 36" tall (with the wheels retracted).
