Well we pull up and he says to me, "Go in the bed of the truck, and get that bucket of used oil," So I get it, he pours used motor oil over the remaining 4 pipes and post. He told me to wait 15 min and watch this Sh!t, He picked up his E-Wing hammer smacked each post and pipe 1 good time, and grabbed them with a pair of channel locks and wiggled them right out. No sweat.
Could you elaborate a little more? This could be some real handy info. Condition of the concrete, steel, and oil? Type of hammer? Where and how did he hit it? Etc.
