thanks guys. It came out really good and didn't cost as much as I expected. I think I have between 400-500 tied up in it. The initial buy of lumber and nails and stuff wasn't that bad. but right at the end, the plywood, tin, hinges, pipe, temp gauge and vents pretty much equaled the cost of the lumber. I thought I was going to come out real cheap on the deal and within the last 3 days of building the price kind of doubled. but I expected it to cost around $1000, so $400-500 wasnt too bad
