[Elecraft] simple iambic paddle

[David Cutter]

As others have said, my first paddle was a hacksaw blade but take care of 
the sharp points!

Better is a strip of pcb material, or 2 strips with a separator for iambic. 
>From memory I used about 5mm wide and about 40mm from the fulcrum, which can 
be just a wood block with 2 slots cut and a screw through to pinch together. 
If you start to get ambitious, you could make the whole keyer/oscillator on 
the pcb, perhaps a TIC keyer.

I did this to fit inside the base of a Norcal 20 with the paddle sticking 
out of the side to which I screwed a pair of Kent paddle handles.  You could 
just shape the pcbs into large finger pads.
