I'm trying my hand at it now. Sun shields will probably fit inside the
plexi windows and be something stiff like that honeycomb signboard cut to shape and covered with aluminum foil and then maybe a film of cellophane or clingwrap to keep from scratching the soft plexiglas windows. For the glareshield over the panel, I'm making a pattern from cereal box cardboard, then cutting 016 aluminum to fit, then covering it with 1/2" thick foam and then maybe leather or naugahyde, or whatever. How about some ideas here. And thank you for your support. Nice article about sunshields at Avweb, interview with Kennon on how they do theirs and what they recommend and why. |

I would recommend using something other than aluminum for the glaresheild unless the aluminum is rivited very well to the instrument panel, and has the edge rolled. A sharp sheet of aluminum is like a knife if it ever gets forced back into the cockpit... Putting a slight curvature in the panel to make it deform upwards rather than trying to come back would also help. |

cardboard, then cutting 016 aluminum to fit, then covering it with 1/2" thick foam Choose your foam carefully so that it doesn't give off toxic fumes or catch fire in case you're slow getting out after an accident. Good luck! Ed Wischmeyer |

A sharp sheet of aluminum is like a knife if it ever gets forced back into the cockpit... Strange you should mention that. I remember seeing a glare shield made of 1/8th inch plywood and covered with naugahyde. It had the neatest set of teeth prints on each side... I'd not rivet the glare shield to the panel though. Screwed down? you bet, but not riveted. You might have to fix something in there one day. Myself? I think I'd use a sandwich made of foam and extremely thin aluminum bonded and covered with leather or naugahyde. Something with "crushability", but not only strong enough to hold its shape, but a heavy mug of coffee, or wrenches, or....

How about Coroplast? It's light, it's stiff, it's cheap. It's not particularly UV resistant, but covered with foam and fabric, that shouldn't be an issue. For those unfamiliar with the material, Coroplast is like corrugated cardboard made out of polypropylene. It's available in various thicknesses. You can pick up small pieces of it at sign shops.

I remember seeing a wrecked Bonanza (stall on takeoff) with a complete bite taken out of the top of the panel. I was told it had belonged to an orthodontist. No, I'm NOT kidding! ![]() Rich S. |

Tim Ward Have you ever worked with the stuff??? It is as bad as aluminum for slicing, and it has the distinct disadvantage of being inflexible. Particularly the stuff used on greenhouses etc. |

There is a family of RC airplanes that are made from this stuff. Fairly easy to fabricate and pretty tough...

Fairly easy to fabricate and pretty tough... See: http://www.duraplane.com/ -- Dan D. http://www.ameritech.net/users/ddevillers/start.html I've gotten paper cuts working with corrugated cardboard, too. Covered with something, I think it would crush more easily than aluminum. Also, I was thinking of the thinner 2 mm or 4mm stuff. Don't the greenhouses use 8 or 10 mm thicknesses? If you slice along the corrugations occasionally, you can get an approximation of a smooth curve. On second thought, since you can form it using a heat gun, maybe it wouldn't be such a hot (hah!) idea. It can get pretty hot in a closed cockpit. It wouldn't be good if it sagged from the heat Tim Ward. |
