Here are a couple of pics I took this morning of my 1/32 basswood-based sloppy interpretation of your simulation of the sharpener nose cone.

I haven't had a problem flying my Mark II of a 1/8" rod. The one screwy flight I had turned in a weird direction quite a few feet off the pad so the rod had no influence on it.
The real sharpener has much subtler ridges. If I build another Mark II, I plan to use slivers of 1/64" plywood or tiny styrene strip to simulate them. (or make a mold of the sharpener and make them from resin. And if I do eventually do that, I'll tell you guys. Don't hold your breath.)
