Well well look who showed up…

It is still hard to tell what’s going on with the axle of this Pro-Yo 1. Ah wait. I took the string off and it is **definitely a full metal axle** , not a wood transaxle.

So the Pro-Yo 2

- screws apart in a rational way
- uses a wood transaxle, not a metal axle
- has _large_ wooden sides on that transaxle for a “wooden response area”

In addition to verifying the metal axle, I see zero provision for any kind of response inside the pro-yo 1, no starburst or anything, just the (one piece?) metal nut that makes up the metal axle.
