First that is a fine looking young man working in your shop... get a face shield on him.
Second, it's great when you can spend time with your children. I didn't do woodworking when my little one (he's 36 now, stands 6'3" and weighs about 250..but still my little guy), but everything else he wanted to do I tried to be a part of... not to the point of taking over or smothering him, just to be there and watch .... we're still close today.... he took up pen turning after I did, but in separate locations... he bought me my first lathe(a Ridgid spindle lathe) as Christmas gift and a number of pen kits to go with it... we played on the lathe in the garage that Christmas day and he decided it was so much fun he went home and bought himself a pen lathe. He turned for a while, then college, work and girls all got in the way and he wound up giving me the pen lathe as well. We still talk about pen turning even though he doesn't do it any more.
One thing he did that I haven't tried yet, he used to make cross bows... he hand worked them in his living room... don't think he has time for that now. But he made several that were quite the work of art.
