I make these keys for fun, as a hobby, they are really for either collectors who can't hope
to own an original or that special CW operator that wants something more than the standard
Vibroplex action to test his skills as an operator

I am in the process of moving my website to this new domain so some links won't work 
until the move is complete, if you need any info contact me on the contact link below

As you can see on this page my construction notes
and pictures appear as I build the keys, however
when the page is full and another page is started
I slowly remove these from the previous page leaving
just one picture to save on space, But if you have a
YUH key and you would like to see how it was made
let me know and I'll forward anything I have on it.
All these keys carry a lifetime guarantee, (my lifetime
not the keys) if they should fail in someway or need
to be modified contact me and I'm sure we can come
to a suitable arrangement.
