Anybody have any tips on how to do this?

I've spent hours of super hot rocket style burning, probably burned half a tree, lol and it still won't budge.
At this point is it still a toxic danger if I leave it?

Susan Pruitt : This and the comments posted below should solve your problem, some people go all the way and make a "Pocket Rocket'' to help them burn off
the various oils, paint, epoxies , and other organic materials but if you use 6-10 layers of paper mache` you should be fine !

Link below :

Please use good judgement when viewing anything on U-tube, there is a lot of crap out there !

This is where i recommend going to Rocketstoves.com to download your PDF Copy of '' rocket mass heaters "

This assures that when you come back to discuss all forms of Rockets you will be using the same terms to describe the Sizes, Shapes, Materials and the Orientation
of the Rockets parts both by themselves and to each other ! Hope this was us full and timely

For the Good of the Crafts ! BIG AL

thanks guys - Yes I'd watched that video several times and failed to mention that I used the paper mache method. It worked well for removing the black exterior paint but only barely scorched the interior coating in the very bottom. I'll take pictures tomorrow. I notice the barrel in the video is smaller so the amount of wood to keep a fire going all the way to the top is smaller. Mine is 55 gallons - maybe I didn't get it hot enough? I had a roaring fire going in the bottom half for at least an hour and fiddled with it for two hours.

It looks like Teflon and I've been told it is "phenolic epoxy". Googling indicated it would only come off with chemicals or grinding, and I'm not planning to spend a day with my head in a metal barrel with a grinder, lol.

So I wonder how toxic that stuff is if I just leave it. If the fire didn't phase it maybe it won't off-gas either? Any chemistry experts in the crowd? Meanwhile, I'm starting the quest again, to just find another barrel without the coating.

Susan, food grade barrels are notorious for the "dreaded red liner." It won't burn out. I'd either accept it since it's on the interior and will vent outdoors if it ever does start to burn off, which I doubt it will do, or find a new one that was used for something other than food.

Yep, as Matt said, why bother burning something on the inside of the barrel?

Thankyou thankyou for writing - you've saved me a lot of work and angst. I wonder why I didn't come across any reference to the "dreaded red liner" before - but now it's here for others to be forewarned

How would using this barrel anyway be different from the cautions against using galvanized duct close to the fire ?

Having renovated two old houses with oil furnaces and ancient filthy ducts with real effects on my health, one of my main goals here is "clean air". Oh well, I'm getting old so what's another year off my life anyway lol.
