DON'T HINGE IT. Trust me, read, I'll explain.

Here's what you do. Get a good 8' by 4' piece of whatever you want. MDF is fine. Get it with a good finish on it.

Cut two 3 foot wide sections. Now you have two 4' by 3' sections. When placed together, it's a 4' by 6' table which is your bare minimum that you want. Once you mark off your 3' by 6' area (or place a mat down) then you will have 6 inches of space on either side of the playing area for your cards, etc.

On the underside of the table top you are building, secure some bumpers that allow you to line up the table top to the table you are setting it on (screw in some small pieces of wood). I suggest 3 per half, so you can slide the table on or set it on gently. Then secure 2 window locks to secure to two top sections together. The small little flip locks are perfect for this. Now you can lay two separate table toppers on using the bumpers to line them up, then secure them with the window locks. The entire thing will be very snug this way and will NOT shift.

If you want to get fancy (like I did), you can use the remaining 4' by 2' section on the end to have a flip up extra space area. I attached 1 foot sections to each side. So the tabletop sits on the table all the time (for the most part), but I fold the wings down. When I'm using the table, I pull the wings out and they snap into place. Use REALLY good restaurant table hinges for this. The ones that fold into a 1/4 circle when folded up, but then extend into 2 intersecting half circles when extended. I use two for each flap, but 1 is probably good enough if you are only doing 1 foot sections. If you want a bigger table without the flaps, just cut the 8x4 into 2 sections.

Why should you not hinge it? Because a piece of plywood is like 65 pounds. Add hinges, pumpers, and other hardware and you have a gigantic, hinged, 70 pound table topper that is a pain in the arse to pack install, remove, pack away, etc, even with help. It will be nearly impossible alone. Were if you leave them unhinged and just have them connect with window locks, you have 2, smaller, more manageable sized pieces that you just hook together.

My table is two 4'x3' segments with 3 bumpers. Connected with the window latches underneath. This makes standard 6'x4' table. Each large segment has a wing that can be pulled out that locks into place. that provides more space for dice, measuring tools, a larger playing area, etc.

It takes 5 minutes top to get it out of the closet, set it up on the table and lock it into place all by myself.

I coated the entire top with a textured coating of black plastidip (although any kind of spray truck bed liner or flexiseal or whatever would work). I painted the sidelines, and painted very subtle deployment lines. Then I splatter painted with a wire brush to create a colorful cluster of stars. It looks awesome, and any game mat you put on it won't budge at all due to the texture. It's also easy to handle and put away/deploy.
