$4 mod to see what it changes - I poured 2" of concrete in the bottom of the drum to act as an additional heat sink. Do you think I just created a longer get-up-to-cooking-temp time with little benefit ? (and just added 60 lbs of dead weight?) I was just trying to improve on the set-it and forget-it of the drum, and temp swings when opening the lid.

I only thought of this because I'm in the construction trade. Concrete/sand is often used to add thermal mass - "thermal enertia" for radiant floors, concrete filled cinder blocks for a greenhouse - or more closely related to this, a thermal mass wood stove, which is a 30 gal drum inside a 55 gal, with the space in between filled with mason's sand.

I'll let it cure until the weekend and give it a burn to see what happens. Whacha think?

I think you just lost 2" of usable space and added a back brace/lifting belt to your wish list.

Slappin that bass like some delerious funky preist!!!
