Question about Woodcraft and Berea bushings

[qquake]

Woodcraft has their Princeton pen kit, which is the Berea Virage, I believe. Woodcraft calls for the same bushings for the Wall Street II, Pluma, and Princeton kits. The Wall Street II is a Sierra, if I'm not mistaken. But on Berea's website, the Virage and Sierra call for different bushings (32A for the Virage and 20A for the Sierra. Anybody know why?

I have used them interchangably without problems. However, I never depend on the bushings alone. I always use a digital caliper also.

Hi Jim,

The diameters of the 20A and 32A bushings are the same, 12.0mm and both fit inside 27/64 tubes. The difference is that the 32A bushings are shorter than the 20A. They did this to help facilitate fitting two tubes at once on a standard length pen mandrel.
