Subject: RV8-List: Heavy Wings on RV-8
Has anybody out there done something other than squeezing the trailing
edge of the light wing in order to correct a heavy wing problem? Has
anyone discovered an aerodynamic cause for a heavy wing?
I'm stumped.

I had a similar issue with using a non self-etch aerosol primer.
I would recommend alumiprep, then alodine, then the primer, the
alodine is the conversion coating that gives you better adhesion.
Alternatively, you may get good results with your scotch-briting and
then an aerosol 'self-etch' primer.
Even with scotch briting, you may want either alumi or metal prep or a
'self-etch' to take care of any traces of oil/grease on the surface.

I use cadSTD, http://www.cadstd.com/ has a free and a pay version. 2D
only, but that should be fine for electrical diagrams.

Has anyone fitted the A600 individual pedal mounted brake reservoirs
from Aircraft Spruce in place of the firewall mounted reservoir? If
so, I'd love to hear from you with any service experience to support
the modification approval process we have to go through here in the
UK. Do they do the job as intended? Are there any issues with them?
How resolved? etc.
Many thanks,

OH - good fun - another primer war!
Chet, I used several primers. I sprayed primer on the entire inside of
the fuselage using several brands of self-etching primers. I sprayed the
fuselage using a spray gun and a gallon of self-etching primer. I used a
fresh air ventilator while doing it. Then I primed other parts using rattle
can self-etching primers. The SEM worked fine and is readily available. I
scuffed first with scotchbrite then cleaned the metal with Dupont 210
cleaner or with MEK. In one case I did not get good adhesion so I stripped the
parts and scotchbrited them again and reprimed. The second time held.
There is a lot of opinion about whether to prime and how much and what type
primer. So, I'm just telling you what I did. We'll know in 35 or 40
years whether or not my efforts were worthwhile. By that time, the internet
will have been replaced by mental telepathy - so send me your thoughts at
that time.
I recommend priming any unprimed parts with self etching primer after
cleaning with some type of metal cleaner to remove body oils and other
contaminants.
You may want to check with the paint shop you plan to use (or a
professional painter) to make sure the primer you use is compatible with the planned
top coat paint.
Good luck and thanks for starting the primer wars again. They're
entertaining.

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

| Subject: | Re: Brake reservoirs |
Richard,
I put those reservoirs on my 8 and they were easy to install and problem
free. I suppose the only issues that could arise would relate to where th
e final placement of the the pedals are in relation to the firewall. They
could possibly contact the firewall if the pedals were in the forwardmost
position and you placed the pedals leaning forward. Not the case on my pl
ane and I'm 6 ft tall. Filling the break lines from the bottom up into the
reservoirs was a little tedious using a mirror to check the levels as the
fluid filled the reservoir and getting all of the bubbles out, but presum
ably if the system is leak free it will be the last time I do that for a
while. I guess you could also overfill the reservoir to where fluid would
spill out when tilted. I guess I'm just trying to think of possible probl
ems you could encounter but actually I had no problems. All in all it wasn
't too bad and they have been trouble free. I'm glad I did it. It seems a
little more elegant than all of those plastic tubes and connections. I do
n't remember what I used to seal the threads. It might have been pro-seal
or maybe teflon tape. Hope that helps!
