DON'T SOLDER YOUR BITTIN IT

To many constructors, soldering is the most unsatisfactory part of their work. All too often one sees a poorly soldered joint surrounded with a mass of flux. In s pite of the . many hints and articles on soldering, there persists this inability on the part of many amateur s to make a really good job of soldering. In the writer's opinion, the main stumbling-block to good soldering is the absence of a welltinned bit. So many " solderers " never tin their bits at all, but simply run a blob of solder on—and wonder why the thing won't work! i

To tin a bit, heat the soldering jron to nearly red heat then rub it vigorously with an old file and plungei into a tin lid in which there is a smear of flux and a blob of solder.

Each " face " of the bit shouldi be

so treated, and the result will be a tinned bit.

But all this will be useless if (&) the joint, (b) the flux, and (c) the blti are not kept scrupulously clean. i
