boil kettle design

[martinworswick]

i currently use an electric element in my bk but i'm thinking of converting to gas as i would like to be able to whirlpool the trub and hops out,i would also like to make my bk do double duty as another vessel which requires a 4 inch rjt fitting,this leads me to my question-
would a 4 inch hole at the top of the bk be sufficient or will it be acting as a lid?i'm thinking it would be ok but has anyone tried this? i'm not a fan of dms so i want to make sure i get rid of it!

Regardless of the DMS concern, I would be concerned about cleaning.

Perhaps a design with an open top, that can be sealed up would suit both your needs...

hmm,something like that may work! although i can get my arm quite a way through a 4 inch hole,i think i'll look around to see if there are other fittings which are maybe 6 to 8 inch that arn't super expensive
