Well, if you want to pick a nit, you might try posting a link that is somewhat relevant to the topic. I saw lots of search results telling me PVC pressure ratings, proper application, etc. Funnily enough no ratings that apply to bending force or suitabilty for use as a pry bar, although I don't see why it wouldn't be strong enough. (there were some mentions of bending/flexural strength, but they were mostly applied to pipe at a certain pressure or under a test condition not easily transferred to sticking a bar in the pipe and pulling - although again it's probably strong enough in the 4" size).
My comment regarding your bar being weakened had nothing to do with PVC. If you were physically capable of applying enough force with less than 3 or 4 feet of leverage, then I think your bar is weakened. I don't care if you used titanium pipe as the lever, I was referring to the amount of force being applied to the bar, not the instrument transferring the force.
I stated what I did and you doubt what I am saying..
Says who? I don't doubt what you're saying, and never said that I did. I used some 3" PVC today to show my son how to use a cheater to get extra leverage so he could get his bike tire off. I don't doubt that a weakened bar could be bent back with some PVC, but I also don't doubt that it has been weakened. Has it been weakened enough to be a concern? No idea, but if you used a 6 inch piece of pipe to bend it back by hand, then I wouldn't trust it.
You do not know what you are taking about, just the crux of the matter.
What is it you think I'm talking about, because you don't seem to be addressing it very well....
