When the war started for the US, Japan was at about 80% of its maximum industrial output. The US was just coming out of the great depression and 50% of its existing factories were unused. Yamamoto knew this and warned the Emperor to no avail. The Mk14 magnetic exploder was developed just before the war but due to budget constraints only 2 live test shots were done on a target ship. One torpedo failed to explode and the other sank the ship. It was then declared ready to deploy. Sent out with a known 50% failure rate. Here began the problem; all complaints went to rear admiral Christie who was in command of the south west submarines (Australia) who also happened to have been in charge of development of the magnetic exploder. What's he gonna say? 'Yea, we sent you out with junk'? No, he refused to allow commanders to deactivate the exploders and blamed everything on the captains. Eventually admiral Kinkade became his boss and authorized deactivating the magnetic device. Later, tests using fishing nets proved the torpedoes were running an average of 8' too deep (missing ships under them). Turned out to be the device used to calibrate the running depth mechanism was itself out of calibration. Finally, after retrieving dud torpedoes fired at a cliff, it was determined that the contact exploder firing pin was too heavy and impact inertia would fracture them before they could fire the detonator.

Today's Featured Article - Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
