HELP!! Help me Frank, help me ;)' I found a really cool new type of penetrant yesterday to help me get some of the rusted parts off like the nuts holding the manipulator arm control rod, the thrusters, the emergency flood cap, and front lighting tubing. Would you believe that the Halogen car light bulb still works. It might not be the original one, but it's still been in the pressure casing for years. I took the light housing assembly apart to see what it looked like. When I removed the acrylic lens a bunch of silvery black powder came out. I suspect that powder is from some sort of reflective coating that was painted on the inside of the 6" metal pressure casing? I don't know what good it would of done since the GE Halogen bulb is right next to the acrylic lens. I was also wondering if you turn that light on when the sub is out of the water, wouldn't the acrylic over heat? Also the acrylic lens looks to thin for use to 250' fsw? Here are 8 pictures of that original lighting assembly taken apart. http://www.frappr.com/?a=viewphoto&id=2628470&pid=10110599 Also interesting to note, the Halogen bulb was kept centered and wedged in place with three pieces of cut rubber hose. http://www.frappr.com/?a=viewphoto&id=2628470&pid=10110592 Regards, Brent Hartwig From: ShellyDalg@aol.com Date: Tue, 1 Jul 2008 10:32:01 -0400 Subject: Re: [PSUBS-MAILIST] I dropped the drop weight on a K-250 To: personal_submersibles@psubs.org Congratulations Brent.
