Yeah, no. We had Erector, which fucking sucks. 1) It's a step above pot metal. Literally scrap steel. Yield strength of zero, which means when you bend it, it's bent. And it bends really goddamn easily. 2) So structural integrity is added by stamping it. So all your "i-beams" are these dimpled pieces of shit that go straight, straight or straight. Want to put them together at an angle? Guess what? You just bent it. Irrevocably. 3) Nuts are square. Bolts are round-head slotted screws. Threads on nuts are deliberately looser than threads on bolts, so you can't fully attach shit. 4) Plates were plastic, and brittle plastic at that. They'd bend until they broke. Or, if you left them out in the sun at 7,000 feet, where I lived, the UV damage would reduce them to autumn leaves in a day or so. Erector is such shit. I'm so glad it's dead dead dead. You could try and build the shit on the box, but the erector set you got for $30 would build, like, nothing.
