Draw off boxes

I have my draw off box mocked up now. Here's a pic of how it will look when welded on. I didn't weld it on yet because this customer didn't request it. I'm itching to get one welded on. I took a ride to a small sugarbush about 40 miles away and got a look at his waterloo/small raised flue pan he wants me to make one similar. I was glad to get some ideas for my float/ float box. I'm really looking forward to my new brake for doing flue pans.

I will have a draw off fitting welded low enough to get complete draw off.
