Coming back from our first (since restoration) trip to the Canyon. Riggers out for the bridge.
Looking great! Need some new knobs on those throttle/gears.
Good catch. Bought silver ones that were supposed to be for DDEC single lever controls, but the threads were wrong. Any suggestions?
Aren’t those hynautic? Should be easy to source.
You could clean them on a buffing wheel and keep coated with 303 vinyl/plastic protectant. Might bring the color back.
I double checked. I purchased the Schmidt & Ongaro 50040 knobs, that were listed for Hynautic and DDEC. Unfortunately the threads are wrong.
Can’t you just run a bottom tap through the threads on the knobs you bought to match the threads on the handles?
I considered re-tapping them from 3/8-24 to 3/8-16, but I am concerned that there would not be enough remaining thread. Found a custom shift knob shop and ordered another set in what I hope is the right thread.
You can tap from fine to course (24 to 16) and should be fine, especially given these is nothing structural or critical. Going the other way, from course to fine is more difficult. You can also drill it out and epoxy in an insert or tap to a larger thread to screw in an adapter. But, sounds like you’re getting new ones.
