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.

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 <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!

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.

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!

| Subject: | 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.

| Subject: | Re: Spar cuts for dihedral |
What I am wondering is does the wing attach fittings/bolt take all the loads and
if people are cutting the C.S. spars with a gap and no butt joint, why could
we not cut that angle all the way back to the first rib on the C.S?

What methods have you guys used to apply the epoxy on to the ribs/spars without
wiping it off while sliding on the ribs? Maybe you position the rib first then
epoxy around it?

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.

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.

Thanks Jack. That is exactly what I had planned to do, but hoped there was
some better way that I just wasn't thinking of.- Your website, by the way
, is very cool. I refer to the pictures from time to time to see how you di
d things.

| Subject: | No bugs on the prop or windshield |
22 degrees on the ground this afternoon when I went out for a fresh
afternoon flight. The Piet really performs nicely in the cool air. I
flew the A-65 Piet, pulled the prop thru 8 times, 2 shots of prime and
left the primer open and it started on the first pull.
