Taken from a brand new rotor casing, never assembled.

.394'' inside crook

2.09'' outside crook

Hope this helps.

Joe,

I know for a fact that the MW2145 uses a notably wider crook than my MW2165. Perhaps my 2165 is an older design but all the new 2145s I've seen are definately wider.

I know this because I had a double whole step slide made and ran into this very issue.

FWIW

Joe,

The dimensions are off the ports of the casing or as you put it ''legs'' that go to the slide.

. . . . I'm looking for various widths of TUNING SLIDE CROOKS that Meinl-Weston makes for their various .807" bore applications (mostly: piston CC 5th rotor & Hilger's F 4th rotor) on their various instruments. I simply would like to order the very w-i-d-e-s-t .807" bore crook that Melton makes "stock". . . .

FWIW, just in case the company's catalog does not list those particular dimensions: Manufacturers normally specify a center-to-center distance--rather than outside and insde-the-crook dimensions. I would measure the outside diameter of the tubing, then subtract that tubing diameter (also equal to two radiuses or radii

) from the across-the-crook dimension to obtain the center-to-center specification.
