Hello guys. I recently acquired an Iron Cobra double pedal. And, it has the slave pedal wobble issue.
I looked for a fix and the tip i found consists of merely tightening the screw which secures the ball bearings inside the "barrel." (hard to describe.) here's the link to that tutorial.

So, I examined the issue. And, I thought that the problem lies in the ball bearings not fitting snugly in the barrel.
So, what I did was I inserted a piece of paper to make the fit tight.
That cured the issue!!! No more play. No more wobble.
I took pictures. But it's really blurry. But I hope you get the idea.
With the paper inserts. Just trim the excess and replace the plastic cover.
Another angle for a better perspective.
