What's the usual diameter for coping on a mini-ramp?
I think 2" (5cm) is the common size. 2.5" is way too much.

Well, direct from the "Thrasher presents How To Build Skateboard Ramps"
book:

Coping for a mini-ramp is the same as for a vert ramp. Your best choices are
2 3/8 inch to 2 3/4 inch steel pipe, or actual blocks of cement pool coping.

On the mini that I built, I used scaffold pipe, which is 2" (5cm) as Antti
said.

hth!

Having the coping stick out (and up) the right amount is more
important than the diameter (given a reasonable range, say, between
2" and 3").

In fact, bigger coping will feel smoother than smaller coping
(given that both stick out/up the same) because the bump will be
gentler (the "transition" between the ramp surface or deck and
the coping).

So I'm going to target 2.5" in my search, but take whatever I
can find +/- half an inch.

I just noticed that the poles that hold up street signs seem
the perfect kind of metal - smooth but not slippery and just
about the right diameter (that's here in Toronto, I don't know
what the poles are like elsewhere). I called a bunch of pipe
places but nobody had anything like it. In fact, one place
educated me about the definition: He said that I was actually
looking for something technically called a tube, not a pipe,
and that's why none of the pipe places had anything like it.

some might suggest a late night rendezvous with a spanner in a nice quiet
industrial estate might get what your after. Or if you're a good fellow, a
quick scan for local traffic/safety sign suppliers in the local business
directory would be a good place to look.
