I need a large outside caliper and can't seem to find one. My friend has one that measures 25" when fully open and 26" top to bottom. He can't remember where he bought it. Any suggestions? Thanks.
 
For a one time or quick use you can make one from bare #10 or 12 copper wire with the tips filed round. This can also be used to measure wall thickness deep in a hollow vessel.

Not my idea but I saw it done at a demo by I think Ellsworth.

It would be easy to make your own from 1/4" plywood or Masonite. A 1/4-20 bolt and wingnut will lock it in position.
 
I checked the online catalog and it isn't listed. The Caliper is 24" with jaws that are about 3+" deep and has a vernier scale. It has no part number, just "Made in China" as its only markings

I found it in the store and your local store may have it too. The stores and catalog don't always match.

I think we’re talking about two different kinds of caliper here. (see the attached pics) It is my impression Paul is looking for something along the lines of the second example.

One of the ways I find what I’ve seen, but don’t know the source, is to do a Google image search and then follow links to see if I can determine a source and better search terms. In this case: https://www.google.com/search?q=cal...w=1093&bih=606#tbm=isch&q=woodturning+caliper
