Keeping the plane light means not adding ounces anywhere. Keeping it light long term means having external protection of any sort that lowers water (humidity) absorption. The plywood as designed and properly installed is certainly strong enough without fiberglass. If a fiberglass layer is added but delaminates over time due to locally poor adhesion against areas of the wood, water could be trapped between layers in the worst circumstance. However, without some form of light wight, very mildly structural plastic on the outside, water intrusion due to humidity is inevitable unless the whole plane is stored permanently. Nothing was wrong with Ken Rand's design, and no fiberglass skins were called out. The advent of certain materials technology should be used to lower the overall weight. I am using 2 oz crows foot satin fiberglass over the plywood to lower the risk of water (humidity) intrusion and obviate the need for filler materials. Dacron is even lighter, but crows-foot satin fg is very light, adds a nominal amount of strength when combined with the plywood, and damps out a bit of the acoustics of the mahogany. --Skutch ---- Original Message ----- From: "Ronald Freiberger" Date: Wed, 19 Jun 2002 19:39:53 -0400 To: "KRNET" Subject: KR> Fiberglass on Fuselage > > Common practice on Plywood, like my Cassutt and Jodel, is to cover with a > light cloth like 2.7 ounce dacron, or sailplane fabric.

Would that meet the requirements? Somebody with more time on their hands than I have might look up the exact regulation, but I'm thinking that they require 400,000 candlepower. We've had this discussion before and I think the bottom line was that even if the DAR insisted on 400,000, he almost certainly wouldn't have the equipment to measure it or prove that you were inadequate. And then there's the debate on HOW it's measured, because the regs aren't real clear on that either, I don't think. He might make you prove that it's certified as a next best resort, but I doubt he'd go to that much trouble. Others have said that if it's a strobe and it flashes, that'll probably get you by with no questions asked. It's like a lot of things in the experimental category, it all depends. And we're talking night certification here. They aren't required for daytime use.

This digital scale is made by Escali, it weighs in both: * ounces - up to 176oz (11 lbs) in 0.1oz (1/10oz) increments * grams - up to 5000g (5K) in 1 gram increments The scale includes a "Tare" feature, which allows you to measure the weight of an item, without including the containers weight. One of my favorite features is it's tempered glass top (6.25" diam), this glass top really makes cleanup easy. Also, I really dig the "George Jetson" look this scale has. There's lots more to tell you about this scale, the URL below does a far better job of showing you the scale and it's features. Even if your a die-hard epoxy pumper >:) you'll appreciate this scale, and the ability to calibrate your epoxy ratio pump accurately with it. As for the company selling these scales, they are very reliable and quick to ship.
