I like the iron pipe elbow idea as it does not involve welding (and of course I don't have a welder). You would think Blackstone would put that little weld right at the end instead of back like that. I would think that would probably solve the problem. I definately need to modify mine as I did have the grease want to travel over that little weld and run down the leg a few times when I was cleaning the top after cooking. I think it is the inrush of a larger amount of grease that caused the problem.
Thanks for the ideas!!!
