> These were 1/2", 3/4" or 1" inside diameter pipes with one end crimped closed in a vise. The open end was driven into the ground and the crimped end prevented the top from mushrooming as it was driven. The resulting narrow flat strip was often center punched at the correct distance and line.
Famous rural surveyor: "A punchmark!? Now that would just destroy the beauty of a 2 1/2" cap, wouldn't it?" 😀
:good:
Always described a found monument of any kind by what you see and measure. Don't call a rebar a #5 rebar unless you can see the number 5 on the side. Say 5/8" diameter rebar if that is what you measure. Same with the pipe. Forget what and how they come up with the "nominal" size. If you are able to measure 3/4" I.D. across the top of the open-ended pipe say that. If you have to measure and estimate 1" O.D. at 1/2" from the top of the pipe, say that. Measure what you see and report what you measured.
That's my opinion.
