Hi Terry,

good to you that you catched on this, as it is the usual method for
production repining. So the long center pins are available in the US ? I
like the fact they burnish the cloth,it is faster than using a burnished
separately. Many other advantages, as you state.
Are you using a "pinning plank" to be at ease and pull the pin straight also
?

Pre glued bushing flange are thickest than many old parts, but  they sell
also 5 or 6 thickness of bushing cloth in strips, that you have to glue
yourself (and graphite , they recommend !) pure wool is considered the good
choice (while I never seen "Wool mark" mark on cloth !.

Have just an idea about the graphite on the bushing cloth : its presence as
an hygroscopic material, allow possibly the flange cloth to react more with
humidity , then more thickness is obtained while the hole enlarges because
of more humidity ? Let's stay positive !

Best Regards.

  I don't know anything about Schaff's bushing cloth and cutting cloth, etc.
I have been using Renner pre-cut & pre-glued bushing cloth strips and using
their flange bushing cloth sizing tool:

=EN  These materials and tools have made rebushing flanges painless and
perfect everytime for me. Renner's long (about two feet) center pins are
very handy also when doing a bunch of flanges. Joel Rappaport (I think it
was him - the guy that does Tanglewood) did a class at a convention a few
years back on this method.
