Exactly... that is what it usually boils down to when it comes to things like making your own furniture, flooring or kitchen cabinets. If you charge yourself for the time you need to put into the job, you will often come out way ahead just buying things. BUT... that's not the point. I do have a small business on the side and frequent the local craft shows, and for that work if I don't clear $15-20 an hour I won't do it. So far I've managed to to meet that goal for the three years I've been doing it. I dumped it right back into the shop, and that has paid for thousands of dollars of machinery upgrades.
However, thats one thing... making things in my woodshop for myself, family or close friends is entirely another thing. In that case, it's not the cost or time... it's the camaraderie of friends in the shop... it's having a piece of furniture made from that tree your Grandfather planted 100 years ago that blew down. It's making something unique that you can't buy from a furniture store at ANY price. Example... I kept the wood from the old wooden crib that all three of my daughters spent their first years in, and one day I will make something for each of them that incorporates some of that crib wood somewhere in the piece. That's far removed from how much does it cost and can I get it cheaper from a big box store. I get the feeling you didn't know what was involved in putting a cherry floor in your house from trees on your own property, and that's OK. However, I do understand that you might feel it is something you would do even if it was more expensive and full of aggravation, which it probably will be if you still want to do that. Life is not always just dollars and cents... or should that be "sense"?
btw... don't feed him (her?), just ignore him
