Here's some pictures of the tip I mentioned another post. I wanted to use 12 gauge but couldn't get it . I had a piece of 6" sch 10 so I used it instead. Also, I ended using 1/4" s/s carrige bolts intead of rivets and really liked the way they worked out. I ground the square collars round, ran then through from the botom and consumed what stuck through with a tig torch.
Thanks for looking.....
