Been working on my uds. The first barrel that was given to me had mo lid and the red coating on the interior. I've been holding off burning it because I couldn't find a donor lid for it.
So I started checking Craigslist sent a few emails off, one guy couldn't meet up until after Christmas, another didn't answer, third guy says he thinks he has two drums left. We decided to meet up today, since he was almost an hour away I emailed him this morning and wanted to confirm everything including the color of the interior.
The guy emails me back and says its silver inside and out, no rust on it, he thinks its stainless steel.
So I jump in my car and drive about 80 mph to meet the guy.
Turns out the barrel is galvanized. I decided to take a chance on it and got it anyway. I recalled reading around here that mecuractic acid takes zinc off pretty quick so I stopped by home depot on the way home.
$6.96 for a gallon of acid, about half an hour layer I got bare metal on the inside of the drum.
Rinsed it well and sprayed it down with Pam.
Didn't quite get the acid to the top rim, took that off with the angle.grinder.
Will do a good burn tomorrow and start drilling.
