Got my table built. Ended up 49" x 90". Bought some 2x8s and ripped them down but that was probably more work than necessary. I bought a sheet of 3/4" MDF and had them cut it in quarters so it fit in my car. I ripped them down a bit more on the table saw. I ended up basically building a torsion box anyway minus the bottom skin. I used pocket screws. It’s not perfect but it’s pretty flat (certainly more than the floor of my garage). Back to assembling the LR3 now that I’ve settled on the width!
