Soldering a PCB with homemade resistance tweezers

[furld002]

Hi. How about telling your viewers hoe to make a resistance soldering machine.

I know I could use one.Looks like it would come in real handy in making model boats like I do. Thanks for the videos.

It's just two pieces of 1/4" brass rod held apart with a block of plastic. Diagonal holes at the business end hold of the device two pieces of pencil graphite, secured with #2-56 screws. The other ends are attached to a 12 volt DC power supply. I drilled holes in the backs of the rods and used a couple more screws to secure the wire ends inside the holes. See watch?v=LWzZKi0_uac&feature=pl­ayer_detailpage#t=109s for the complete setup. (sorry about the lighting.)
