One of the struggles of Family Build Night is that we're not using power tools (except for drills). The other is that so far, we're mostly using cheap-ass wood. This means that I don't have a good baseline for what's possible. This was a particular struggle with a project an adult participant recently, where I just didn't know what was possible, so I didn't know to what levels I should be able to spur him on.
This morning I sat down with the same tools we take to Family Build Night, with some 2x2 scrap left over from last night, and decided to play with a possible leg for a small table. Not sure how to introduce this to the scene, I don't want it to be a dick-waving "look what I can do", I want it to be a "here's what's possible in an hour or so if you focus."
