[Elecraft] K2 VFO encoder / control board close fit

[Don Wilhelm]

Mark,

The instructions packed in the encoder envelope tell you to flush cut 
not only the pins on the encoder board, but also the leads on the 
control board that might contact it.

If you do not have flush (or shear) cutters, and want inexpensive ones, 
look for Xcelite (or Lufkin or Cooper) 170M shear cutters.  They can 
often be found in your local Home Depot.

In addition to flush cutting the boards, put something on the back of 
the encoder board - fish paper would be best, but a piece of flat 
plastic cut from one of the many plastic wrapped consumer products would 
be good.
Paper or electrical tape will eventually puncture.
