Finally getting things into place in my garage: finished the electrical, painting, and insulation batts in rafters.
1st option: I took a look at other flip top stands that use 5/8” to 1” thick steel rod down the center sandwiched between an upper and lower 3/4” plywood for platforms. But something does not “click” right. Would this design over a year’s time, bow the platform from 30lb-70lb machinery 1/8” or even 1/2” at the front and back edges? I’ve never dabbled with hardwood plywood or even baltic birch plywood as of yet to know just how sturdy and strong this design could last.
2nd option: 3” height, 16” wide, 20” length torsion box. I know I will have to jump into the torsion box design eventually for my 3’x5’ work surface so have read alot about them and understand the mechanical advantages and am really eager to get started (I felt like I am 43years behind other LumberJocks here, as I have only this year really found my wood “calling”). The torsion box design would be fantastic, as it gives superior strength for the material used (1/2” MDF for example) over a wider expanse. But I can not figure out how you bolt or lag screw something like a planer to the torsion box when the material used is MDF and also, how 30lb-70lb machinery will physically impact the MDF where the steel rods penetrate thru.
