A few of you guys have fuselages, and need cores. I also need some more cores. To that end, I have been rebuilding my foam cutting tools. I still have my cutting bows, and somewhere in the mystery box pile are some 90 degree templates, etc. Not having a suitable power supply, I found a how-to article on the NSRCA website, complete with instructions, schematic, and a bill of materials. I scrounged up a few parts from work, then a trip to my local Radio Shack store netted me most of the components, a few were ordered from Mouser and Allied electronics. The photos show the pile of parts, and the finished item. The problem is, it doesn't work. I will ask my boss (Master's degree- Electronic Engineering) what my stupid mistake was, then it will be "all good". So for now, I will put this aside and sheet the beat-up but usable wing cores that I have on hand. Providing that I am distraction free for a bit, I will have some wing pics to post in a few days.
