So, I did a little research and I found this forum.
I wanted a pellet smoker and I got a lot of inspiration from other builders here who are using the Smoke Daddy pellet hopper ...most notable were @Scootermagooand @Dennis CumminsThanks for the inspiration guys. .

I threw out the old insulation. I've had several basement floods and it smelled pretty funky.
Then I scraped out as much black tar as I could
That's it for now.
