How to repait quadrant knobs?

[albertomannil]

Hello friends, any suggestions how to repair Piper Arrow throttle knobs?

Throttle knob is probably just a good polish. What about the prop and mixture knobs?

Thanks!

There was a gentleman on the piper forum that machined the knobs out of billet aluminum and had them anodized. Looked great. A few years ago he said 25-30 a knob.

Select fire sells them, may be who Racerx referred to. https://www.selectfirellc.com/Piper-PA-Series-Mixture-Knob-Aluminum-_p_174.html Prices are at $25 for prop and mix, $30 for throttle.

Looking at address I think you're right. At the time I think it was more a side hustle.

Is there a 3D print option maybe?

Get a billet one and be done with it. Plastic gets soft in a hot plane.

I’m just here to say ‘knob’.

I’d say “props to you,” but the mods would probably cut me off, or at least throttle my usage.

Following, this looks cool, for the machined knob finish. I wanted the TOGA button on my throttle but wasn’t sure how the wiring would work, didn’t really want a wire just hanging around. Post pictures if anyone did the upgrades. Thanks.
