In our morgue you will pass through a set of 6 identical "slabs" (morgue tables) all complete with bodies in body bags. What you won't know is that 2 of the tables may hold live (undead?) actors.
So I have to build 6 morgue tables. 4 need only hold a lightweight prop body in a body bag; but two of them need to be sturdy enough to hold live actors.
For the lightweight tables I started with a 6'6" by 2' cut of 1/4" plywood. I built a lightweight frame of 1x3s which I assembled with the help of our brad nailer. For the curious the side 1x3s were 6'6" and the end pieces that fit between them were 22 7/8".
Once the frame was assembled I flipped it over (plywood on top) and nailed the top onto the frame. Then flipped back over to work on the legs
For these lightweight tables I'm using 2" PVC pipe for my legs. To mount them to the underside of the table I cut 2x4s down to 22 7/8 (to fit inside the frame) at each end and drilled a 2" hole in both ends of the 2x4 - allowing space to slide the pipe into. Now the 2" PVC pipes aren't exactly 2" wide - but I couldn't find a hole saw bit any closer than 2" so I had to make do with a slightly larger hole than the pipe...
I actually found some thick tape that I stuck inside the holes to help the pipes fit more snugly.
