Good of you to include a spot for him at your bench. I have no children, now age 74, modeler for many decades. I keep no models, give away to friends that want something in particular, otherwise there is no shortage of kids to give them to.
In good weather my garage door is up, summer shop is there, winter it's inside. Neighborhood kids hear the compressor working and head that way, often I'll spend some time showing them how to build, detail, paint, etc. I supply them with older kits I don't want, give them Exacto tools, cement, paint and such, BUT, only with the consent of a parent.
First two shop visits MUST have parent to accompany, this is a different time we live in. Kids can take models home to work on, then come back to show and get progress reports. Now, some of the Dad's, brothers, sisters and their friends find their way here, many of the Dad's have never built a model and find they enjoy it as a family activity at their home.
My wife LOVES that the models find homes other than here, "dust catchers" she calls them. Foolish woman. Plastic and balsa stick models come out of here, the free flight models have really caught on and are popular in this neighborhood. I'm in wet Western Oregon, model building is a very satifying hobby in winter.
I'm having tons of fun doing this, well worth the time, in my retirement it gives me something that is full of enjoyment. One Dad told me the best thing he has noticed is his son not spending time at video games now, I have to think of that as a positive.
That's what I'm doing to pass the tradition along.
