Screw on casters to the “bottom” of the base board (which will be the top while upside down right now)
GET A BUDDY: Flip the build over onto the casters. Be sure they are LOCKED to avoid rolling. The Kallax is super light, but the base board should NOT be, thus the buddy system.
Cut the table top to the width of the Kallax, and the desired length. I matched the length of my table top to the depth of the Kallax + width of the table top. This means that, when stored, it will slide down even with the Kallax.
If you are looking for longer table top, just know the table top will not lay flush in “storage mode”, but there could be cool applications for a sticking up section.
Test your build so far by sliding your table top into the open space between the Kallaxs (Kallaxi?). They should be secure, but not scraping. A little wiggle is ok.
Place your table tops as desired (likely connected, but I’m not the boss of you) and mark centerlines for toggle clamps. Two on each Kallax, each side (so 4 total on each side) and one across each side of the table divide. (This holds the table top to the Kallax and then to each other)
Screw on the toggle latch clamps. The hooks should be on the table tops’ sides, the clamp parts on the side of the Kallax. These NEED to be tight when secured. The table to table clamps can be any combination you want. Getting the clamps lined up and screwed on straight while avoiding the screws already involved in the Kallax system is tricky.
And there you have it! A gaming table that has storage for kids toys (on the front) and your gaming books and boxes (in the back, facing the wall).
Looking back, I would have loved to add a large TV in the middle of the table top (for DnD maps), but the framing would have added width to the table and not have been as compact (which I needed). I wish I knew enough of building to maybe have a way to allow more of an edge on all 4 sides, not just 2. The clamps made this impossible, but I am still looking for future builds.
Also: would have loved to use swing arms to slide the table tops out from their storage space instead of having to lift them up and lock in place. But I’m not a smart man and this task was too technical for me (is that even possible?)
This hack has a lot of expanded potential. This is a great jumping off point, and I’d love to see if anyone can use it to make a more simplified/ extra version. Cause I’d love to make another one with a bit extra.
