Hey Devocean I was hoping you would chime in here!
yeah I built the stand off rockets design but messed up the for the sump or I could not add the 2nd set of legs. it is wood glued and well as pocket screwed. then I added 4 L bracket for the side support. like I said not the best work I have done but it been doing great for over a year but now while I have it empty I want to beef it up and enclose + make it pretty for the GF most importantly eh? haha
if I was to redo it all over again I would do a 100% plywood stand and no 2x4s but I have this unless you expert wood working say it a very bad idea to skin this and use it I will keep it and work with what I have.
was looking at 3/4 Baltic birch ply but it $115 a 4x8 sheet oh my but did look nice tho...
I would totally keep what you have and skin it, it would be rock solid, and look pretty.
Shop around, birch sheets are less than $50 here, it would be hard to imagine a reason it would be so much more for you, try another box store, or better a lumber yard if any near.
Yes I remember now your sump issue back when, too bad, the doubled up legs going top to bottom would have made plenty strong, but really a ply skin added would be just as or maybe even more so
