ha, yeah, so that's you at mytractorforum.
To be fair, I found a place that made shifters with buttons, and the cheapest one they had was a cue ball. Then I found your post that gave me the confidence to do it myself. My parents' pool table has glass balls, so it never occurred to me as a possibility. Of course the orange ball was perfect. An 8-ball would have worked too, which is the first thing my wife said. I like the orange.
The parts diagram shows the tube being hollow, so that sucked when it wasn't. Made the knob a little harder to fab.
I got split loom to cover up the wire yesterday....
