| Subject: | Yet another priming question |
Hi Fellow RVers,
Does anyone have experience with Tempo zinc phosphate aerosol primer for internal
priming? Tempo's zinc chromate aerosol primer is listed in the RV-8 construction
manual as being an acceptable priming option. Apparently Tempo no longer
makes the chromate, and says that phosphate is the new equivalent. It sounded
like a great way to go, given that I can prime my parts individually with a can
primer. I tested it first on some scrap 2024 T3. I scuffed the surface with
Scotch Bright, then cleaned with MEK. Then I applied a light coat of Tempo. But,
48 hours later, I was able to remove the primer by lightly running my finger
nail over the surface; there was almost no adhesion. Did I do something wrong?
I don't need to use Alumiprep if I use Scotch Bright, do I? What about SEM
self-etching aerosol primer? Does anyone know anything about that?
Thanks, Chet Stringham

reception?
Problem: On the ground at KAWO (non-towered airport) I can't get Seattle
Center (and my IFR clearance) because of my RV-8 belly-mounted comm
antenna. (In a high wing trainer, this is not a problem.) I have a
bubble canopy--can I add an antenna within my canopy to the existing belly
antenna with
a
combiner/splitter to my comm receiver and achieve better reception on the
ground without degrading my in the air reception/transmission? Ground
plane problem with this setup? I can't easily place another antenna on
the top
fuselage. Suggestions?

I have an antenna on my RV-8 slider which works pretty well. It is on the number
2 comm.I riveted an aluminum sheet to the aft end of the slider for a ground plane.
The
cablegoes to the front of the slider. The front of the slider is about as far in
front of theshoulder harness bracket when closed as it is in back of it when open,
so a loop
from the
slider to the bracket works well. The whip goes through the canopy with a rubber
grommet.
I have some pictures but they won't get through the list.

I was planning to download and use TurboCAD LE to design my electrical
system, but it looks like there might be an installation problem with
Windows XP. Is this true and is there a solution? If not, is there
another free, user friendly CAD program that I could use?

Stan,
I used the ExpressSCH schematic software. You'll have to build some of the components
but it's very easy to learn and use. Their site is:
