Welcome to Craft Forum Cooter! I saw a few pictures of your bulldozer and now I'm going to see if you've posted more pics. Nice job! You put a lot of detail into it!
Since some of your work is for sale, be sure to post about it in the Business Forum, which you can find on the index page.

... you know your work is very appreciated when your wife won't let you sell it. She sounds like a smart lady.
Have you ever thought about selling the plans to other wood workers?
