Friday ended with some great scores...all "free" but not so fast! Like a 15 lb brisket stalling, my UDS build has stalled for now! Getting ready to leave work and a friend brings by an open head barrel in excellent condition. After work I stopped by a car wash to spray out the barrel which appeared to almost smell like a cooking oil (maybe) had been in it...could have been motor oil...I have no idea really. After the car wash I was trying to figure out where I could pick up some pallets to use for the burn off and there it was, a new still empty strip mall with a pile of scraps and a couple nice pallets behind it. Score! On a roll I'm thinking! lol Got up Saturday morning and unloaded everything. Broke the pallets down, measured out my 3 - 1 inch air intake holes and drilled those out in preparation for the burn later in the evening. The one downside was the barrel has that red paint type liner inside it. Got the burn done last night and thought I'd jump up this morning and start running my wire wheel to clean out the residue of the liner and this is where I hit my stall! Using a half inch drill and a 4" wire wheel I go to town first on the bottom side of the lid. It was proving to be pretty tough stuff. I take a break from the lid and figure I'll hit the inside of the barrel and bam, this little wheel isn't much of a match for the task at hand! argggggg Plus I don't think the drill I'm using has enough rpm's to really get the job done....I've done a lot of aluminum parts polishing in the past and I'm sure the lack of rpm's is killing my motivation! I'm going to make a couple calls tomorrow and check some prices on getting this thing sandblasted on the inside. Thinking maybe if I spend a little more and get a wire wheel for my 4" grinder it may go better? The barrel was hot as you can see in the following picture. Any other suggestions short of sandblasting?
