The step with hinges in place. They hold the step and keep it from slamming down unexpectedly
Ever since it was built I've cringed when kids are playing around up there because the step is a very long and heavy piece of wood and I've been worried that fingers could easily be hurt if the step were flipped down while a hand was underneath.
I recently solved this issue by installing a couple of resistive hinges that keep the step from swinging freely. You need to actively swing the step down to close it and it cannot close unexpectedly.
Meanwhile I'm in the midst of building the desk project I wrote about recently. Hopefully I'll have phase one (the desk cabinets) done soon and can start to put it all together.
