'Any ideas on the proper (or close) knob for the ends of the control stick?
Are they Bakelite?

' Here’s what I used to replace the weathered knobs in my airplane: https://www.mcmaster.com/#threaded-knobs/=17a1jjn Go to McMaster-Carr and search threaded knobs, ball type, and scroll down to search. The site is not the best to search. You want item number 6050K35. They are currently $3.38 each. On the selection chart it is Style number 4, 2 inch diameter, 1 9/16 inch high with a 3/8-24 UNF thread. These are a dense black plastic that perfectly matches the size and shape of the originals, as well as the knobs on Aircraft Spruce friction lock throttle cables: http://www.aircraftspruce.com/catalog/appages/frictionth.php The only color available is black, which might not match your original color – a sort of tan on my airplane. That didn’t matter to me, as someone had replaced the original throttle cable and knob to black anyway. If you really need to match another color, paint them. If your throttle cable is OK and you just need a knob, get this one for $4.50: http://www.aircraftspruce.com/catalog/appages/frictionth1.php Tony Lowe 1940, F24W-41A, N28522, S/N 136 From: David Pattee patteenews@gmail.com [fairchildclub] Sent: Thursday, April 20, 2017 12:13 AM To: fairchildclub@yahoogroups.com Subject: [fairchildclub] Flight Control Stick Knob

'David, Great response Tony. To answer your question, yes Bakelite. They were from the Willis Jeep stick knobs. As Tony stated, only black in color. You could paint them with two part with flattener to match the other knobs. Currently my customer has Bakelite coming from Russia. Assorted sizes to machine into stick, Throttle, and other control knobs. Bakelite is not available in the USA. We moved on. The Russians have not. The new modern plastics don’t machine as well. Softer. Hope this helps. JST From:

'I looked at the knoba on a hand beading set to tubing. I think that the set came out of Cleveland. The knobs are identical with one exception, the threads are female versus male.But if you can get them through a vintage auto parts place, great.

' I put PTT switches in those stick knobs I got from McMaster-Carr. I chucked them in my lathe and drilled holes into the center with normal HSS drill bits. I used a small boring bar to size the holes just right for my PTT switches. The material of these knobs does not melt or soften when hot, nor does it produce a continuous chip. They drill nicely with a very frangible but firm, small chip that appears to be just a black dust. I think the material in these behaves quite a lot like Bakelite – definitely not soft – a thermosetting plastic, not a thermoplastic. I don’t think it will melt no matter how high the temperature, but rather burn, like Bakelite does. Just one more clarification – I did not intend to imply the throttle knob from Aircraft Spruce was the same item as the McMaster-Carr knob above. The throttle knobs have a smaller thread – I think it’s a 1/4-20. They are the same size and shape, though, including the same knurled band around the “equator”. They look like they are made from the same material, in same mold. It does not appear McMaster-Carr offers those knobs with a thread size that small, so if you need one, buy it from Aircraft Spruce and you’ll know they are compatible with their throttle cables, and will match your stick knobs from McMaster-Carr. You can buy this cable: http://www.aircraftspruce.com/catalog/appages/a800.php if you are bound and determined to have an FAA/PMA approved part, and swap the knob out for this one:   http://www.aircraftspruce.com/catalog/appages/frictionth1.php   That’s what I did, probably unnecessarily. The non FAA/PMA approved cable is the one I mentioned earlier: http://www.aircraftspruce.com/catalog/appages/frictionth.php It comes with the big oblate spheroid type knob you want. By the way, as far as I can see, there is no externally discernable difference between the FAA/PMA approved and non-approved throttle cable assemblies, other than the knob style. I cannot imagine there is any difference of any kind other than the knob style.

David, Great response Tony. To answer your question, yes Bakelite. They were from the Willis Jeep stick knobs. As Tony stated, only black in color. You could paint them with two part with flattener to match the other knobs. Currently my customer has Bakelite coming from Russia. Assorted sizes to machine into stick, Throttle, and other control knobs. Bakelite is not available in the USA. We moved on. The Russians have not. The new modern plastics don’t machine as well. Softer. Hope this helps. JST From:

To:   Stick Knob Here’s what I used to replace the weathered knobs in my airplane: https://www.mcmaster.com/#threaded-knobs/=17a1jjn Go to McMaster-Carr and search threaded knobs, ball type, and scroll down to search. The site is not the best to search. You want item number 6050K35. They are currently $3.38 each. On the selection chart it is Style number 4, 2 inch diameter, 1 9/16 inch high with a 3/8-24 UNF thread. These are a dense black plastic that perfectly matches the size and shape of the originals, as well as the knobs on Aircraft Spruce friction lock throttle cables: http://www.aircraftspruce.com/catalog/appages/frictionth.php   The only color available is black, which might not match your original color – a sort of tan on my airplane. That didn’t matter to me, as someone had replaced the original throttle cable and knob to black anyway. If you really need to match another color, paint them. If your throttle cable is OK and you just need a knob, get this one for $4.50: http://www.aircraftspruce.com/catalog/appages/frictionth1.php Tony Lowe 1940, F24W-41A, N28522, S/N 136 From: David Pattee patteenews@gmail.com [fairchildclub] Sent: Thursday, April 20, 2017 12:13 AM To: fairchildclub@yahoogroups.com Subject: [fairchildclub] Flight Control Stick Knob
Any ideas on the proper (or close) knob for the ends of the control stick?
Are they Bakelite?

Thank you,
