Column Dimensions?

[JMcDonald]

Can you all post the column dimensions (both the horizontal dimensions, and the length / height) of all the popular square-column mills? I have been searching around, and all Ive found is that the Mini mill's column is about 2.5" x 4" including the dovetails (1.9" without). Also, if possible, could you post a few details about it if it is not a simple cast-iron column? Lastly, please include approximate wall thickness of the column!

Looking for:

X1
X2
X3
RF45

And any other common ones, or variations of the above.

Thanks!

My Super x3 has this for size.

29 1/4" tall

5 1/2 wide (Dovetail column is offset towards left side. And is 1/2" deep. Included in overall measurement)

4 3/8" deep

and 3/8" thick (at least on sides that can be measured.)

Here's the X2 column profile, It's 21 inches long I believe.
