Mods - not sure where this thread belongs...
We had our main gate rebuilt about two years ago and I specified that all new steel pipe be used. Long story short this fence guy (I was going to call him a jackass but that's an insult to all of the donkeys out there) bought old drill stem pipe for the rails, at least the posts were new steel.
I was going to stop the job but I agreed to let it continue if they steel brushed the rusty pipe, used Ospho, prime and then paint. Should have made him send that pipe back. All of the rails (horizontal pipe between posts) have paint flaking off, some in huge pieces and some in dime size pieces. I just spent all morning chipping and brushing rust (and then Ospho+rinsing) maybe 35 feet of pipe. At this rate I'm going to be chipping paint for days and days - there's over 150' of these rails left to chip.
Since I was thinking about buying a commercial type of pressure washer I wonder how effective this would be in stripping the rust and flaking paint off the pipe? I was trying to figure out a more effective and faster way to get the job done. Angle grinder wouldn't work due to the fence panels being welded to the rails. What about a needle scaler? I have a dual tank portable air compressor that I could power from my generator but I don't know if it would keep up with that kind of air tool.
Any other ideas?
