Field Plane Stand Plans
#26
If you want a cheap and quick to make collapsible stand, pick up a walker at a garage sale for a few bucks, usually under $5.00, add some 1" PVC uprights padded with foam pipe insulation, and a small shelf between the legs, works great. I've been using one for a few years now. Beats getting down on the ground.

There are a number of safety table plans floating around. Every one I saw years ago when I made a number of stands for club fields were based on 2x4s. They all were robust to say the least. They really aren't overly stable tables with the majority of their weight being in the top, and having only 3 legs. So..........
If you want to improve an already decent design, change the table top planking to thinner boards. Use 1x4s for the top planking. It's absolutely strong enough, beyond strong enough for it's intended use.
With 1" planking, you'll find they're easier to move around the field. They're less apt to blow over (proven by Mother Nature). They're still strong enough to support half-wit adults who use them for stepladders, something that even 1" planking won't make out of them.
