I love modularity. Despite attempts at doing so, I never get the first iteration permanent.
I inevitably design and build something for myself that I then quickly decide needs to be different some how. Having the ability to swap modules around has become a very common set of how I do things for myself.
Others with less of a squirrel approach to things may get it right on the first try. I do not.
Everytime I build something, I want to change something about it.
For a table this big, If for some reason I have dramatically less scrap, I can just use stacking bins for other things.
Now if I was making a shop cabinet set, that modularity might be amazing!
My table is sitting right on top of the cabinets with no extra 2x’s It is a double layer of 3/4 MDF but your torsion top should be even better.
Just need to add some joinery, I think. That is going to be tedious.
Oh…add some extra holes.
I would probably want 3/4 on the bottom for more “meat” for stuff like those casters to screw into. But I also tend to way overbuild everything so take my opinion with a grain of salt 
There is a middle spine top to bottom for most of the table. It is hard, I do want to add a bunch more supports but I think it might be okay as it is.
The way I am seeing. The wheels are holding up the sides, and the bottom runners. Thos bottom runners are holding up the center piece (running in the Y direction). I think the middle stuff will be fine. The overhang in front and back of the wheels is 15" (wheels are at the bessel points).
I was juggling doing 6 instead of 4. As for more meat, I will be sinking in a mounting plate. Just not in the CAD yet.
With the joinery it will be kind of a giant torsion box…I think?
Sounds like you have a good plan! Excited to see it come together!
Well my gut is a 2x4 base…but I have this giant CNC Begging to be used. If it sucks the fall back plan is to add 2x4’s and admit defeat.
The other way to look at it is if I need to add more supports, I might as well just do 2x4’s. I like making stuff, but not thaaaat much.
Yup tedious…
These should also handle the middle section as well. So a little less tedious but still. I know time is CAD saves a ton of assembly time and should make the whole thing a lot stronger.
Heading home to teach a kid how to change an alternator on his first car. Very excited.
Starting to think this tab thing might be hard to assemble.
Any time I build cabinets I cut them on the CNC, but I don’t do tabs like that, I just cut dados lol. Makes it easier to put together. But that shouldn’t be too bad. All the lower parts fitting together first should have it all lined up good for the top parts. Hopefully anyways lol.
I have been thinking about that the whole time. I really don’t like the look of tabs. Dado’s all day…but my table isn’t flat enough because I knew I was going to be transplanting it…and I will finally have something that looks “CNC’d”.
Trying to make a clear yellow brick road. I could stay on saw horses and flatten the table, but that is just janky. So tabs should allow for an easy square flat assembly and a clear path of what other builders might do. Everything after this…dado’s.
The other thing is DAdo’s take extremely less time to design. These tabs suck to work with, it takes forever.
I am almost done, then I need to try out some test fit parts to get the tolerance right.
I like tabs so much better than dados… 
And reduce rigidity!
I like the crossed frame concept, and the tabs but wonder if you’d be better off just building separate carcasses for the drawer units and sliding them in?
I’m not following. Let me try to get a shot of the drawers.
The double depth drawer is a little narrower so it can fit past the sliding surfaces.
If there is an easier way I am all in!
Here it is now, just need to add pin holes for the organizer shelves. Need to pick the pins before I make a hole…honestly think I should use dead endmills as pins.
I am very open to style suggestions, heck even color suggestions. I do plan on using a lot of particle board, and OSB (mostly OSB).
With Glue do you think it is a big difference? I know if I was just screwing this together that would be a thing, but glue and brads, maybe a couple screws was my plan.
do you have adequate access to install/remove/change the shelves after assembly?
