Hi Jerry...

Yes, I have one of the old NC-100 gearboxes in the attic, and it would
be great if there was enough room. :) They had a great feel.

The extra bushing out front would be ideal. Do you recall whether the
encoder shaft will accomodate it and still have length for the knob?
I'll have to pull the cover off one of mine and see.

I presume that the encoder shaft is more than a half inch long, like 3/4" but I don't have that radio and haven't had the knob off my radios that do have encoders but Yaesu encoders don't necessarily match TenTec and I don't notice instability of knob rotations. All the bearings I suggested are 1/4" long.

BTW, I used the term "wobble" in my earlier post, and that was a poor
choice of words. The knob does also appear to wobble, but that is
another issue that can be helped by re-positioning the skirt.
