[Collins] kwm-2a dial speed

[yash at aol.com]

Have been playing with my Kwm-2a and have really enjoyed using the rig. 
Mainly on 20 and 17 meters.It was a lot of work ,but paid off ,flawless 
operation and the rig looks as new.
    Any way ,my question is this. Collins stayed with a 1/1 tunning 
ratio in the main dial of the kwm-2a ,this can make the rig a bit 
touchy for fine tuning and since there is no Rit for the collins, I was 
wondering. Has anyone ever fitted a vernier reduction drive to a kwm-2. 
Say 4/1 or 6/1. I have one on my sb-102 Heath and it works very well. 
So much easier to tune in, than the collins.
        I have looked thru the archives  and can't find anything 
relating to this. If anyone could give me some direction about this ,I 
would be greatful.
thanks
