I am somewhat new here and have not posted much, but I am a diligent searcher and researcher. I recently purchased a char-griller and the side firebox attachment. I have been reading countless threads on the weaknesses of these units and the modification necessary to get the most out of it as well as better overall performance.
It seems like the majority of people are taking 2 3/4'' pieces or angle iron or aluminum and creating a channel that runs along the front and the sides of the main grill area, then using a permatex high temp sealant (the red stuff) to secure a 3/8, 5/8, etc fiberglass stove rope by rutland.
I was in a bbq shop today wandering around and noticed that all of the big green eggs, kamada joes, and other ceramic styler smokers all have a high temp felt strip around both the top and bottom of the lid. They also had spare gasket kits for sale. I did some research and these high temp felt gaskets are rated to over 750 degrees F and have an adhesive backing that is peel off.
Is there any reason pro or con to using this adhesive felt gasket from big green egg, kamada joe, bayou classic, or other brand from amazon to seal my char griller?
I contemplated taking the gasket and creating a U shape around either the top and/or the bottom to create a good seal, but after further thought, the friction of opening and closing the lid could cause the adhesive to weaken and pull off the lid or base. I think 1 piece of angle iron to create a flat mounting/mating surface and then this felt laid all along that surface could create a better seal than the grapho glass stove rope.
side note.... I just located a company that sells 1'' strips of this Nomex High temp felt for $.77 per foot. There is no adhesive backing, but a general spray adhesive or the high temp sealant should work too.
