Well, Willis Snyder utilized very high magnification photos of center 
pin bushings (clogged with verdigris as I recall) in some of his 
classes over the years. So my imagination may be vivid, but not 
especially original.

Given that you certainly reamed many more teflon bushings in your work 
at the Manhattan School (likewise for Joel at UW-M), I will defer to 
your judgment that roughed reamers are AOK. Jon Page's suggestion of 
Joe Goss' reamers is also helpful; I've got those but I didn't have 
them with me yesterday morning.

Thanks,
