Metric Center Pin Sizes

I think German piano wire gauges are being mistaken for center pin 
sizes.  German piano wire sizes differ slightly from American gauges, 
but Joe Goss asked about center pin sizes.

German center pins are not identified by any gauge, but by their 
thickness, e.g a pin with a diameter of 1.30 mm is called "1.30".  Very 
simple, actually.  Center pins are available from 1.10 mm through 1.70 
mm in increments of  .025mm  (.043" to .067" increments of .001")   The 
conversion factor is 25.4.  

The traditional European method of (re-)pinning uses 60cm (2 ft.) long 
center pin rods.  One of these days I might write a little piece on 
that.  If anyone is interested in these rods, visit my website:
