Editors’ note: This is part one of a two part ordeal which took place from 2004 to 2005. It is the longest and ugliest recounting of the events surrounding my futile attempt to certify Tripoli Level III. I have tried to keep the post interesting by adding picture links, a couple a videos, as well as many usefull links to interesting websites…see highlighted text through out. Continue reading Level III Certification – Part 1, A Lesson in Futility (very long)  Electrical Switch Lock I am electrical intolerant; I know that if I push a light switch up, the room illuminates, and vice versa. I like simplicity when it comes to avionics, and these Electrical Switch Locks have that required characteristic. I only need the switch to reliably arm my avionics when I need it to, and power down to safe the altimeters and pyros without issue. I have used switch locks for years, and I try to tell anyone who asks, that Electric Switch Locks are an excellent and reliable way to arm rocket electronics with just a turn of the key. As seen in the photo, the switch lock is a simple barrel type lock. Keying can come in many forms, what is pictured is a single bitted barrel key, which fits a lock mechanism that rotates ¼ turn for actuation. This type of switch lock, and all of the ones that I currently use came standard issue on many computers prior to year 2000.

Many Years ago, Radio Shack used to be on my model rocket supplier list, as the vender for Super Lube® grease. It came in a little gray tube, and fit nicely in a field box. Those of us who are avid fliers, used this synthetic grease to lube o-rings and liners for our motors during the reload process. “A little goes a long way” are the words we used to describe the product to ‘newbies’. At sometime between the last time I purchased a tube, and the time that I needed more, Radio Shack stopped carrying the Synthetic grease. Continue reading Super Lube Vs. Dow Corning 111
It was one of those designs that kept me up late one night in 2003, staring at the ceiling; I could see it so clearly in my head that I could virtually touch it! Nonetheless, if I did not get it on paper, it was going to fly right out of my head! |
