Ed, If we are to guess it's size it would be helpful to know if it's sitting on toilet paper or paper towel.

That would make it too easy Steve.

It's about 14" long and 1.5" in diameter.

By the way 

Now I know why my M10's seem tight. I always made them 1 or 1.5 pitch! Mmmmmm.....1.25

Worth the dive. 6" x 19" x 5/8" aluminum (aluminium) plate.

Ed, your killing me with all this dumpster dive scores. Stop it, I can't take it any more. I need to stop watching this thread but I just can't. 

I've got one more piece to bring home then I'll cool it and give you a break Steve.

Throw them things out and go Yankee pitch. They won't do that to you.

We stock both, yankee on the left, metric on the right. The metric cabinet will never be complete because of all the sizes available. What a confusing system, I bet half of them are cross threaded assemblies..

Personally I disagree with your statement about the metric system being confusing.

Both have what is considered 'standard' fine and coarse pitch threads. Yes, you can have two options for fine metric threads (e.g. M10x1.0 and M10x1.25) but you also have UNEF and UNS in the "Yankee pitch" system. For example, I have at least four different varieties of 5/16" bolts, with 18, 20, 22 and 24 tpi. I also think I have some 5/16-28 but I would have to check.

You may recall that I posted about the different drawbar threads on my NTMB30 tooling for my mill. I have tooling with M12x1.75, 1/2-12 and 1/2-13 pitch threads.

I've grown up using both systems and have no major issues with either system

Nice score Ed, but the scrap you find even looks too clean. Get some dust and rust on it to make it respectable scrap.
