Are they even made in that mm style? However in today's search I found a 2-20mm set of R8's in a wooden rack for $55.00/set, bought two sets. That ought to fix that problem. If they aren't loaded with runout.
I also see the proliferation of 3 phase stepper driven servos, in sizes up to nema-52's and 30+ nm's. Freight will slow those sales, $65 for small singles, up to $250 for a triplet of 20nm nema-42's. But you could do like we used to say on cow barn radio 50 years ago, lemme turn the house around. I had a high gain 623 with mods, and a pdl-2 antenna with a rotator 30 feet above the roof which on that old farmhouse was already 3 stories high. Sick bird? You betcha, but I never used more power that it took to get there. I talked to a farmer in Saskatchewan CA on less than a watt of SSB power many times that year. With the mods, that radio could do 70 watts into a dummy load, sounding like a good hifi on both ends.
