Morse Key

[Steve WithnellParticipant @stevewithnell34426]

 

Always wanted to make a morse key.   This is scratch built to my design,  starting with some salvage mahogany.    I made good use of the KX1 to get the base profiled and then machine some of the trickier pieces like the cast iron saddle and to profile the main lever.

All the drawings I did using cut2d,   I haven’t managed to cross over into 3D cad yet.

The base carries 200g of lead ballast, which brings the overall weight upto around 850g.  The pcb was cut using one of those chinese CNC engravers and again cut2d for the drawings.

Drool!  Lovely job.  I particularly like the knob and spring bridge, never seen anything quite like that before.

Small point, does the lever only earth through the bearings and spring?  If so, might be worth adding a braid strap to provide an earth immune to wear & patina building up over time and eventually causing intermittent keying.   Or will it live in a display cabinet because it’s too beautiful to use?
