If that violates child labor laws I'm in serious trouble. I think your good as long as it's free help. That's my story and I'm sticking to it.
When I was younger and would help some older friends with their houses and stuff they always said it would be cheaper to pay me than feed me.
Bogy, I just saw some pics you had posted of your wood chute that showed an outside to inside view but I can't find them again! Anyway, is the chute made of PVC pipe? How low to the floor does it extend? What supports it? How do you insulate it while not in use? I'm sure you have this info posted somewhere. Looks intriguing!
Fun with the grandkids. My grandson pick up all the chips. Then we have sword fights. What a great time and memories.
Fun for them, child labor for you I gotta tell you, as a little kid I don't think id be able to resist taking a ride down that wood chute
Thats life lessons right there my friend. They will be better as adults because they know how to process Faaarwood.
