We used crest toothpaste at our local gliding club when I was a kid. It acted as a very mild rubbing compound and worked great. I've used the techique on my Stinson with great results but suggest you try a test area first. Good luck. Scott Knowlton Slow piet builder -----Original Message----- From: Matt Dralle Subject: Pietenpol-List: Plexiglass Scratch Repair... Dear Listers, During the fitting of the Plexiglass canopy on my RV-8, I managed to put some pretty disheartening scratches in the windscreen section. You can see from the pictures that they looked pretty bad. A call to Van's revealed that a replacement canopy would be $640 + $250 shipping to California! Ack. So what to do... A bit of surfing and I found this "Scratch Off" windshield repair kit for $35 on the Aircraft Spruce web site: http://www.aircraftspruce.com/catalog/cspages/scratchoff.php Frankly, it just seemed too good to be true. Nothing for $35 could be that "magic" I thought, but what did I have to lose at this point.... Well, the kit arrived yesterday and I decided to give it a try tonight. In a word: WOW! In about 2 hours the windscreen looked as good as new - no kidding - AS GOOD AS NEW! The pictures really don't do the repair justice. It looks better in person. There are basically two sponges in the kit with four decreasingly porous pastes. You just put some of the first paste on the sponge and buff it in with a drill at 1200 RPM or less. Then you wash everything down good including the sponge and windshield with warm water. Then you use the next finer paste and repeat the process. Etc, etc, until you've used the 4th paste that is kind of like car wax. Frankly, the scratches were gone after the first application of paste - I started at #2 based on the instructions and the "observed severity" of the scratch depth. So, the bottom line is, if you've got scuffs or mild scratches in your Plexiglass buy this repair kit. It works!

Textor" Mike, They are 2" Bell-Memphis, BM 24566-3, not sure about material. Got them at OSH for $10.00 a piece. Check eBay, they usually have quite few. Jack www.textors.com ________________________________ Message 4 _____________________________________ Time: 05:37:25 AM PST US Subject: Pietenpol-List: Plexi Scratches From: tbyh@aol.com Another idea for removing small, very shallow and minor scratches is to use toothpaste and a soft rag -- I can't think of the brand name off hand but use one with a little grit in it. I've also used this over the years with model airplanes to remove scratches from canopies and clear parts. And your parts will have a nice, clean minty aroma when polished out! Fred B. La Crosse, WI ________________________________ Message 5 _____________________________________ Time: 06:04:58 AM PST US From: Oscar Zuniga Subject: Pietenpol-List: Spar cuts for dihedral NX41CC is rigged with 3" of dihedral, measured from wing root to last rib outboard on the wing. Computationally, I guess it works out to about 1.02 degrees. As far as I know, there is no angle cut of the centersection spar... there is enough flex of the wing to allow 3" deflection at the wingtip with the spar butts cut square. The wing attach fittings are bolted up and then the threaded fork at the bottom of the lift struts is adjusted until the desired dihedral is obtained at the wingtip. I believe the Pietenpol manual mentions something along these lines or perhaps a bit less (1"?), but no angle cuts of the spar butts that I can recollect.

Maybe you position the rib first then epoxy around it? ________________________________ Message 8 _____________________________________ Time: 08:31:08 AM PST US From: Jeff Boatright Subject: Re: Pietenpol-List: Spar cuts for dihedral The wing attach fittings/bolt take all the loads on my Piet. There is no butt joint between the center section and the wing panel. I do not know if that is to plans. Plane has about 400 hrs on it.

Textor" Mike, Slip all the ribs on; position them just to the side of where they will be. Apply your epoxy to the spar, and then slide the rib into position and clamp. I glued mine, some just nail theirs.
