Hi. I was looking to kill some time so thought I would mount a spinner knob on my 94 B7100. Why? because I like spinner knobs. Got one on my JD5310, F350, even my ol dumptruck has a suicide knob. So I got a fancy one from Kubota. Says Kubota on top in that funky script and rubber like a truck tire around it. Cool. And of course I bought it off ebay.
Unfortunately the hole is way to big for the B7100 steering wheel. There was included a rubber strip meant to take up this space and provide secure attachment. That worked great until I had to use it, then the whole thing rotated inward due to the shape of the steering wheel. The rubber strip fell out and the fancy knob was left hanging there upside down swinging on the wheel mocking me.
Hmmm..what to do.
I could have gone and bought inexpensively another style of spinner knob, one that comes in all different colors and bolts on with machine screws and you can find everywhere. But that kubota knob, it was hanging there, just swinging back and forth, mocking me in it's own little way...
So I came up with this semi-permanent mount method I will describe here.
1st I cut some Kydex thermoplastic into 1x5 strip. Heated it up with heat gun and wrapped it around one of the center spokes near the wheel and let it cool into a rough initial shape.
I then took the bottom part of the spinner knob and ground down one side to equal the thickness of the Kydex plastic (that is two thicknesses since I have it wrapped around the spoke.)
Holding it in position I marked and drilled through the Kydex where the hex head bolt goes through and then loosely put in both bolts.
I heated the Kydex up again so it was all flexible and then tightened down the bolts and while holding the knob where I wanted it, "smooshed" down the Kydex so as it cooled it conformed to the shape of the spoke and held the knob in the correct position.
After it was cool and firmed up, I trimmed away the excess Kydex to conform to the knob shape. There is still a large gap between the steering wheel and the knob opening where the rubber strip was supposed to fill. The Kydex alone is not strong enough to hold the knob so I bought some "God Stuff"
"God Stuff" - as in 'god that stuff is great!' Of course I am talking about JB Weld. In this case the JB Weldstick putty.
Cut off an inch or so and with wet fingers kneaded it into the magic color and then wrapped it around the wheel and (working quickly I might add - god doesn't wait on you) bolted the knob in place tight. As the JB oozed out used a screwdriver as a putty knife and filled in gaps or cut away excess to make it look pretty.
12 minutes later, rock solid. Will need air chisel to remove. Next day little spray with some satin paint and will look OEM. (pictures prior to paint):
"Yup, did that"
thanks
