Earlier I wrote: ---------------------------------------- I currently am assembling my new K3 #820 and have reached the step where I need to mount the VFO A tuning knob. I am unable to advance the knob's set screw far enough to clamp the knob to the shaft and am considering running a tap in and out of the hole to clean up the thread.
Does anyone know the diameter and thread pitch of this set screw? If I hold the screw against an 8-32 tap, it seems to fit, but I am worried that it might be a metric thread instead. ------------------------------------------- I now can report that I took the bull by the horns and used my 8-32 tap to clean up the set-screw threads in the VFO A knob. The 8-32 set screw then went in smoothly, and the VFO A knob now is mounted on the VFO A shaft encoder. I ran intro a different problem with the VFO knob. The knob would not fit on the shaft, and I also could not insert a 1/4" drill bit shank into the knob. I then used a 1/4" drill bit to gently ream out the knob, and it now is mounted on the VFO B shaft encoder. Thanks to Thomas, Vic, and Windy who were kind enough to respond to my request for help. 73, John, no8v _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
