I now have my grandfather's (w3LMB/sk) telegraph key and dearly cherish it. I'm not sure what model or year it is, however it was manufactured by the Signal Electric Manufacturing company of Menomine, Michigan.
I am an active CW enthusiast on 20m. I've been using his key, but it is becoming harder and harder to use because several of the parts are worn out and the key falls easily out of adjustment. Particularly,
there are some screws that have dimples in the end which tighten down on two pins stuck through the key's arm, which they pivot around. Over many decades those dimples have worn and in fact, the walls are bulged
through, and in some places have entirely failed. In a worn out cup like that, the pivot needles also are wearing fast.
The key is becoming increasingly hard to adjust and use, but I cherish it very much and don't want to just lock it in a dusty cabinet and move onto something modern. I want to keep using it, but the more I use it in its current condition, the faster it deteriorates.
Singapore is a very small country and I have very little space here. Thus I don't have a good workshop or access to many tools. It's quite infeasible for me to
do a serious restoration of this key.
Are there any real craftsmen who do "telegraph key restoration" ?? I'd like to get it fully renovated, but only someone highly experienced and trustworthy.
