[Johnson] [Boatanchors] Johnson Ranger VFO Access Question

[Stu Willcox]

I did the identical repair several years ago as well and can vouch for its effectiveness. I believe that I used .030 G-10 material and #2-56 screws/nuts. It was indeed a more elegant solution than using epoxy or rtv to mend the broken micarta. It's still in one of my Johnson rigs, I think the Pacemaker.

I drilled out the rivets and replaced the broken wafer with a piece of thin printed board G-10 material. (I think the PC material was around 1/16th inch thick or maybe even a little thinner.) I cut it to the same diameter as the old one and mounted it with miniature nuts and bolts. It worked out great.  (Yes I etched the copper off of it.)

I took some photos that I will share with the group so folks can see what that coupling looks like.  THis is my first foray into the guts of the VFO beyond simply opening the side panel and replacing the 18K."
