I am in the process of repinning all action centers on a set of wippens, =
and flanges on the back-action. I like using the long Renner pinning =
wire. Unfortunately, in the range of sizes I need to work with, Renner =
only offers wire in 0.05 millimeter increments. This fairly closely =
compares to 0.002-inch increments. If I use the Renner wire, and 1.30 mm =
wire (about 0.051-inch) is just a tad too loose - it would be ideal to =
use 1.325 wire (which would be roughly equal to a 0.052-inch), but =
unfortunately, Renner only offers their wire in the next size increment =
at 1.35 mm.=20

My question is this - does jumping up 0.05 mm (or 0.002-inch) =
significantly increase the risk of splitting the birdseye? Obviously, if =
I used the regular little individual center pins, I could limit the jump =
to 0.025 mm (0.001-inch). Is this a big deal or what?
