That looks tough!!..but nothing is impossible!..Take a look at my friends layout..He has the Mt. Union Brick Yard kiln set-up..These shots don't do it justice...he has all the piping for the gas lines from tank cars to each kiln..water lines in and out...fans cooling finished bricks...exhaust bricks removed on cooling kilns....flicker lights in working kilns and chimneys..with incense burning for smoke...has his dad standing there supervising the unloading, dresses as he was back then....Its amazing to see!!..He scratch built it all...kilns were made from PVC pipe end caps.. So even tho it looks impossible...it can be done with little short cuts...and you'll be proud once it's done to be able to tell everyone, "I made that!" Hope you don't mind Bill for me posting!
