I've had this barrel for sometime now and I'm finally getting around to building my first UDS. It was a brand new barrel and had only been painted (in-n-out) when I got my hands on it.
About an hour or so with the wire wheel and she is looking good from the inside out.
At the same time, also put in my 3 vent pipes and plug welded up a couple small holes that were drilled into the bottom.
Thanks to everyone who has contributed to this site and mostly to this thread... I have just about read every page at this point, I just wish I could remember it all. LOL.
