got me an idea last night as I am thinking I need a mod to use the lid from my CL score on my drum.
I am going to take the lid from a second barrel and set the Weber lid on it trace it and cut it out inside of the Weber trace. Then the lid will fit on the drum lid and it will fit nicely on the barrel. Hope fully the drum is slightly larger inside of the lip for the weber lid to fit. Will let you know later.
I have not gone out to dry fit it but I think it will work. Maybe.
