Nah, got a ways til retirement, but I know what I'll be doing to supplement my income when the time does arrive!
But I am fortunate enough to be able to work from home, so I can sneak out into the garage and cut a dog or two during the work day.
From laying the pattern on the wood until I apply the mineral oil finish, takes me right at 30 minutes per animal. I have a "system" now in which I do about 15 in a batch. Lay them out on a 5' long board, cut the outlines, then cut the puzzles, then apply the oil.
I don't do any sanding or filing as they're very smooth to the touch already. When complete I dip them in food grade mineral oil and let them air dry for at least 24 hours to soak in.
Another fortunate thing is that I'm in a tourist area (the beach), so I have a fresh batch of customers every week during the spring, summer and fall.
My #1 top selling dog, which I never would have guessed is the Dachshund... go figure... then the Shepherd, Black Lab, Beagle, Bulldog, Golden (Retriever), Pit Bull and Pug. I'm sure that will be different depending on what's popular where you live.
I wish you luck with them, let me know if I can answer any questions at all.
