I know I talked about this a while back, # 2 son finally had a little extra time today so we did the two mod's I was wanting to get done. Added another 1/4" plate on top of Fire Box with a 3/16" air space in between. and added top vents to my FB door Got all the fab work done and some of the welding, and he had to leave to check on one of his jobs. Said we would finish it up tomorrow. Here are a few pictures of what we did today, Remember still some welding and quite a bit of grinding and then a little paint.
