A bit longer. I think with the 12" 4-40 I was 4" or so short. I cant check right now, need to go to work (its 7am here). The threaded coplers require t be soldered on the socket end, have never done that and wonder whether its advisable. Do I simply use electrical solder?

I am considering metal pushrod all through with ball link both sides. May be I could get a 2-56 threader jig. It would be useful elsewhere as well
