Thanks to all who have responded to the pin question, it has been very helpful. Acting on arachne sourced advice I decided to try to use a box of pins that I had from Holly Van Sciver which were labeled Bohin 30 x .85 nickel. As we have discovered the first number is the length and the second is the width. Logically, it would seem that for someone seeking a width of .86 mm there would not be a perceptible difference in using a pin that is .85 mm. However, the pin felt different, and did not resist heavy tensioning as well as the .86 mm. Could it be only 1/100 mm less in diameter? Lacking a micrometer, I took Adele's advice and laid 10 pins next to each other to measure them. To my surprise the .86mm measured about .83 and the .85 pins measured .78. So the discrepancy between the pins was not 1/100 mm but rather 5/100 mm. But, more distressing, it illustrated that the diameter measurements of the pins are not reliable. In that many manufacturers fail to list the diameters of their pins, as I discovered when I went on the numerous pin sites provided to me, one would almost think that pin manufacturers are unaware that their purchasers regularly measure their pins with micrometers! I confess that I have never mastered how to add photos to the arachne flicker site, so if you would like to see the results of my pin investigation, ie. a photo of the pins together, and then a photo of each of them laid in sets of 10 and measured with a millimeter tape, I have posted them to laceioli.ning. If someone wants to add them to the Flicker site, feel free. Here is the link to the photos on laceioli.ning which you don't have to join to view. http://laceioli.ning.com/group/tools-and-equipment/forum/topics/pins-seeking -29-mm-x-86?xg_source=activity But seriously, where did I buy these pins and how can I get more.
