.522 according to my set. Also, if you need anything from Woodcraft, I'd be happy to get it for you and ship actual shipping instead of what they charge.
I have that reference copied to the desktop on my computor and it doesnt have the wallstreet 3 in it. It hasnt been updated in a while and I checked the library before posting.
I actually made a Wall street kit pen last christmas for a late add-on guest to the christmas gathering. FIrst kit I have made since the 90s lol.
The beads in the kit hardware lend themselves nicely to overturning.
Many prefer to ignore the stock bushing diameter for this particular kit, and instead go with 0.522 for both the nib AND the clip end. For that reason, JohnnyCNC carries two sets of bushings for this kit... and his recommendation is to use 0.522 for both.
