Navy Flameproof type key knob with disc
Not a perfect copy but the height, top diameter, shaft diameter, top thickness are VERY close. I have the Military specification drawings to MIL-SPEC and the mounting bolt threads are MIL-SPEC correct (10-24). Includes the disc which is 1-1/2", some may be 1-5/8".
Need a different thread size? I can custom make one with 8-32 threads to fit other keys like shown in one of the photos on a Vibroplex. Note-Key not included in photo. Contact me first.
Both parts made from black Delrin rod in my shop in Montana
May come with a stainless steel or brass stud
NOT 3D printed!
Also I have an aluminum and Delrin knob in the photos to look at. It comes with a 1/2" 6-32 stainless steel threaded screw and washer that will fit into an 8-32 (or larger) threaded key lever to be able to tighten from underneath. Message me about it.
