I think the HRO drive, or stacked Jackson Bros verniers (have a size
advantage), or BC-221 drives (once you fix the right angle part ....by
relocating the tuning capacitor ?) can provide an excellent, 30:1 ratio
or
better, solid, no-backlash, solution from the knob to the tuning
capacitor.
The item remaining is the capacitor shaft to the dial. I'm coming to the
conclusion as many of you have .........that dial string works wonders.
As mentioned before, my criteria would be: approx 7"-8" travel plus
bezel, no sub chassis requirement, simple to reproduce with average
tools, inexpensive, prefer all bands shown, weighted knob, looks
professional (like the 898s).
Bezel cut from 1/8" inch aluminum stock ? Maybe thin (1/8" x 3/8")
brass rectangular tubing available at Hobby stores and Home Depot,
soldered together ? Some form of modified picture frame ?. Bring
screws out the back to mount, hold plexiglass face, and mount
second plate with dial markings. Markings on stiff paper glued to the
plate (same technique as on the HBR S-meter).

I think I would make a sliderule window with the HRO gear drive- yes
would be
nice to have it track that scale on the HRO knob BUT- as you say- 73s Lew
