Hi Omann I can see the foto of your evaporator, kinda looks like mine. except I use a metal flue instead of square blocks. The old barn in the background is rather attractive in the photo, too. I will private message you on Maple Trader. Im trying to build a network of Missouri syrup producers and would like to get your email or phone number. Maybe there will be a meeting of syrup producers this spring or summer. Thanks. Uncle John
