[Elecraft] Encoder felt washer

[K4IA at aol.com]

Thanks for the tip.  I personally am not a  fan of the felt washer solution 
in either the K2 or the K3.  Not only for  the reason you state, but it also 
seems like it must wear out eventually or get  rubbed down smooth so it doesn't 
provide friction.  It just seems "Mickey  Mouse" as we used to say.  Leather 
might be a longer lasting answer but I  have got to wonder if there isn't a 
higher tech way of doing this?  How is  it done in other rigs that have 
adjustable drag?

closely I could see some bits of the felt hairs caught in the  C-ring and
bearing. I carefully tugged gently on each hair with tweezers  while turning
the shaft in the direction needed to unwind each one and, after  removing
several of them suddenly the encoder ran free  again.<<

Several years ago I replaced the encoder shaft felt washer  with a leather 
washer cut from an old glove...No more trouble with hairs in the  
bearing...Leather washers are often used in the drag brake in fishing  reels...One could 
probably get useable leather from several sources, including  the tongue of an 
old shoe...
