I might be crazy, buuuuut, if I am not?

just a thought about those screws. Can you make some cups from 3d print to fit inside the tubes, then throw them into the bottom and pour some thickened epoxy to protect the screws.

Either that or coat the screws before hand with something like silicon so they can still be unscrewed after it cures

Either that or just coat them in some silicon before pouring. At this point though I am just going to silicon the rear guard to seal it up, then just fill it with sand then add a silicon to the front plate and forego the epoxy just to see if the weight causes any problems like bowing in the table. If it helps enough, ill redo it with the full on epoxy granite.

I was just referring to a little epoxy to seal the inverted cup. Sand has a way of getting into whatever it wants like water. So the cup wasn't going to be enough.
I'm not sure I understand the silicon / silicone? Are we talking a lube, or a sealing type?

Yes it does, lol. Yes the sealing kind just to prevent the sand from seeping out of the front or rear. Kinda like a home-made gaskit
