One of the challenges of the mission field is keeping older vehicles in good running condition. Uncle Piet and I often joke that we work for "Make-A-Plan Motors." Our most recent project has been a welder for me that runs off the massive Lister diesel engine that also runs our generator.
The welder (in the middle) is made from a slightly modified car alternator. (I rewired it from star to delta phase and made a heavy duty external rectifier.) It's not that powerful but does most of what I need to do. It will weld 3/16" steel with good penetration if I am careful.
Uncle Piet made the intermediate shaft for me. The engine runs so slow that I needed an extra shaft to get the rpm high enough for the alternator to weld.
I finally got the whole set up working this last Saturday. Since then I've been trying to catch up on the backlog of maintenance projects that I couldn't do without a welder.
Thanks Uncle Piet!!!
