@ChefHDAN, thanks for the additional design, had not seen it, I may use that approach for the single-tool carts, I m just honestly surprised that something with that little support and thickness could be so sturdy.

It’s okay, no worries, my first bench was 2×4, double 3/4” MDF with a tempered hardboard top skin. What you’ll learn over time is that structure and how the parts work together give the strength, in the beginning I over engineered everything, and I still do to an extent, but, then, experience is the best teacher over time, design and build to please yourself, that’s really the only person that matters

-- I've decided 1 mistake is really 2 opportunities to learn.. learn how to fix it... and learn how to not repeat it
