David, I've never tried teflon on upright hammer butt leathers, but now that you mention it, why not? It is a great friction reducer, and the jack escapement on many verticals is less than smooth. However, you want the backcatcher felt to make solid contact with the catcher leather, and I would think that greater friction is needed here, hence no teflon on the catcher leather. Also, is that an RPT I see behind our perennial associate's name? Hearty congratulations! You've now joined the ranks of technicians who put letters after their names. Tip: don't use your teflon powder on frying pans (unless you want them to slide across the kitchen floor) It makes the eggs taste funny, too. Regards, 8-) Rob K.
