My question is, can the lid from the open top drum be used on the closed top drum after torching out the top and leaving the lip?
I know i can get a Weber kettle top and made this work but for the time being is this a practical solution?
Take the lid from the removable one, and see if it fits over the rim of the sealed one. You may need to use a pair of vice grips and open the channel on the removable lid some, but if the OD is the same, you should be able to make it work. I relieved my lid a little after putting in the high temp flat gasket.
