I have a very nice cardboard astrolabe, but it is calculated for
40 degree's north. which is about 550 miles south of where I am.
Does anyone have a reference for how one goes about calculating /
constructing one of a particular latitude?

I just googled "astrolabe calibration" and got many sites. I
glanced at a few and realized I don't have the math for this.
But then, I don't have the math for high-school algebra any more.
This is a very low bar.
I suggest you also google "astrolabe calibration" and search
through the sites, and _Deo volente,_ you'll find what you need.
Good luck.

That is the next step.
Or find my copy of Geoffrey Chaucer's Treatise on the Astrolabe.

Well, my copy of that is with my Collected Works of, and it's in
Middle English. :) And it'll be either (a) calculated for a
London or thereabouts latitude, or (b) doesn't mention the
latitude of the observer at all. But the Internet can be your
friend.

And sometimes, it can be that friend who has all sorts of answers,
some of which are relevant to your question.
But' I've found a translation into modern English, and an article
about using Power Point to make the templates. Which has the
formulas. Weeeee!

I am having "fun" crunching all this. I shall be writing up my
notes when I'm done, but I'm not sure how to show the required
drawings in ASCII art. B-{)>
