Curmudgeon said: After the last thread like this, I built 4 of these:

During an earlier thread about a similarly tragic situation Curmudgeon/Jensenman posted a pic with some discussion about the wood pyramid style stands he built out of 6x6's. The picture got lost to the photobucket nonsense but I copied and pasted some of the back and forth:

6x6's predrilled with 10" lag bolts holding them together, then 2x6's across the bottom and top to add a little height. Even if they somehow were to roll over, it's still high enough that you won't get squashed.

Got the plans that you can post? I would like to make some but don't see the lag bolts.

Hidden by the 2x6's. Down through the top with maybe a quick countersink to hide the bolt head and slap on the 2x6 with some deck screws.

I need to gin up some plans and post them. But it's not hard to do: I predrilled the bottom 2 from one side with a long 3/8" spade bit, then used an air impact to run the 1/2" lag bolts in. Then from the top I predrilled 2 holes straight down, I spaced them so they wouldn't hit the two horizontal ones and countersunk the holes so the heads of the bolts wouldn't stick out. Then I air impacted those also, the 2x6's are nailed on. All the lag bolts have thick washers, too. I got the cheapest galvanized handles I could find and used wood screws to stick them on. It could be done without the air impact but man that made it a lot easier. The best part as I noted earlier: even if they were to somehow roll over they'd still be tall enough to keep the car from landing on you.
