Encoder felt washer

>>My old K2 developed that problem several months after I built it. Looking
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...

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? k4ia Craig "Buck" Fredericksburg, Virginia K3 #101 In a message dated 1/25/2008 8:36:40 A.M.

Some kind of air flow control in Ft-2000 - I seem to remember.

I thought it would have required re-adjustment by now. Felt (wool) is good stuff! I think it would be good to have felt washers under the other knobs on the K2. 73, Drew AF2Z _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Many years ago I put nylon washers from the local hardware store under the pot knobs on my K2. It stopped the wobble, gave them a more solid feel, and hopefully extended their life. I did replace one pot and it seems that Elecraft is using better pots now -- at least they wiggle less -- than the ones in my K2 no. 709. But the nylon washers can't hurt. -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.
