I just went to the Ham Fest here in OKC and saw a couple of interesting keys that were home made.  Thought that might make an interesting project since I do some light machine work in my shop.

Does anyone know of any web sites or other resources where there are plans or even good photos of home made keys?  I would like to get some more ideas and then play with a few designs.

tnx and 73

No idea on resources as I'm a bit too far from the USA, but I do have an idea for you.

Most of the paddles I have seen come with small (normally square) bases. What I would like to find is a paddle with a long arm, say about six inches, this gives a bit of momentum to the swing and gives easier operation. I have a mockup of something like this made from aluminum section and it works reasonably well but the standard of my machining is not too good.

Any takers?

W4YA: That article is outstanding.  It contained a lot of the finer points I had not concidered and showed a variety of design approaches.

Mine will not be that sophisticated since I do not have sensitive fingers nor work at high speeds.  I don't think I am even at the limits of my straight key.
