No, I think you do want them close together, your previous idea of keeping them 1 1/2" apart would be ideal. I was thinking if 2 pallets nested completely tightly together, then you would lose the gap. ON the style in my link above the legs fit into each other so you could control the gap by putting something in the hole that the leg fits into to adjust the gap to 2" or whatever gap you want. That would work well.
Bill Cody taught me that some shiner species need much tighter gaps, almost better described as crevices. They need gaps more like 1/4" or so.
I get you. Thanks! Don't know if 1.4 inches is ideal gap, or perhaps smaller would be even better. Do we have any FHM experts who know?
Only issue with nested pallets might be that rocks used to hold open gap might be dislodged by currents over time, thus closing them completely.
