Sorry. I am a bad poster. Sometimes I miss old threads.
I have a pile of scrap metal. I found a piece of aluminum U channel from which I cut out those arms. They must be all the same or the linkage binds. ALSO, be vey careful in moving stuck linkage. The variable caps are also pot metal. Any additional stress on these and you will have a much bigger problem. I made several extras and selected the ones that fit the best.
Mine moves pretty good using the standard tuning but there is very little friction on the "fine tuning" wheel, so it is mostly for looks.
Note also that I used the original brass shafts and had to use solder to reattach. I suppose that a new shaft could be turned on a lathe, but again care must be used not to put stress on the caps.
