New build with recycled parts on a ridiculous budget 120cm*60cm work area

My only concern with those benches is that they will take the weight fine, but once that gantry starts moving about, there's a lot of force trying to move the benchtop in the opposite direction. I have similar Big Dug racking, which is fine once bolted to the wall in a few places, and my old router sat on a similar bench. Might need a bit of diagonal bracing to resist the movement?

These are going to be a temporary measure but I can bolt them to the wall pretty easy if I move them to a different place in the unit.

I was going to sit the router on a sheet if ply which I'll drill into the bench tops as well. I need this sheet for my vac bed, clamps will make me want to murder someone lol.

Diagonal bracing hmmm, if they end up being used longer than I want I will consider it, but I would like to recover the benches for drill press and work areas and getting a cnc is only the start of the puzzle lol.

My Titan drill press is not what you would call professional lol.
