If you look forward to checking your List email everyday (and a lot of you have
written to say that you do!), then you're probably getting at least 0 or 0 worth
of Entertainment from the Lists each year. You'd pay twice that for a subscription
to some lame magazine or even a dinner out. Isn't the List worth at
least that much to you? Wouldn't it be great if you could pay that same amount
and get a well-managed media source free of advertising, SPAM, and viruses?
Come to think of it, you do...
Won't you please take a minute to make your Contribution today and support YOUR
Lists?

Mark,
Do you know anyone who might have one of the flat plate drilling jigs?
After the large hole is cut you place the jig plate into the hole,
square it up and drill the screw holes. Simple and quick.

I am responding a little late as I am reading past mails but since no one
has mentioned it I thought I'd bring more info.
Rivets have a mark on them which identifies the material they are made of.
In our case the dimple indicates that the alloy is 2117 which is the only
alloy specially made for rivets I know of which does not require heating the
rivet (annealing) prior to using it. Other rivets have a cross, two crosses,
four dimples, a star, etc. each one representing a particular kind of
alloy/heat treatment combination.
If I were you I'd stay away from unidentified rivets and from all rivets
which require annealing. Annealing is OK but it is a hassle. The technique
is to heat them with a torch inside a metal basket on which you scrapped
some basic soap - not the Dove or Zest kind. When the soap turns brown then
the temperature is OK. You then have an hour or two to use them before they
harden up again.

Subject: | Re: Position of the battery in the RV-8 |
I originally planned on using a Hartzel CS prop on my RV-8 but opted for
the much lighter Whirlwind 200RV after I had installed the dual Odyssey
batteries (dual elect ignition) in the tail. The CG would have been
perfect with the heavier Hartzell, but rather than tear out the
batteries and relocate to the firewall, I elected to add some lead to
the engine mount. Another option I have is to remove one of the
batteries and replace with a much smaller battery for EFIS and ignition
redundancy. Turns out I only use one Odyssey for starting the engine.
I do have to be careful about overloading the rear baggage compartment
but I really like the responsiveness of the airplane when flying solo.
Three-point landings are easy and it spins and snaps great. As long as
you stay within Van's CG limits you will be safe. On the plus side of
mounting the battery forward is that you can correct a nose-heavy
situation by adding a small weight in the tail. Conversely, a tail
heavy airplane requires a much heavier weight in the nose to correct the
situation.

Excellent info although the specs on the tape limit it to 68F so it should
not do for the firewall. However it could be a good product for the forward

Dave,
Suggest you consider insulating the firewall with 3M Vibration Dampinng Tape
or equivalent. This will provide a fire barrier and also reduce temps to
normal cabin temps. This is a standard insulation for aircraft and is
readily available.

There are some surprises out there. All Davtron mounting holes are non
standard. It's best to check the web sites of each manufacturer. Have
your
panel cutter cut a trial panel in plexiglass for you to do fit up tests
before cutting the aluminum. If your cutter doesn't want to do that,
find
another cutter. (www.engravers.net, Wayne Calhoon) I went through
several
plexi mockups before everything fit. It's realy best if you have the
instruments on hand to do the fit up.

It's not a secret... really. Somewhere in the Aircraft Spruce catalog there
is a diagram of the standard cutouts with dimensions. It might be accessible

Brother, I feel your pain. A couple of years ago my local area paranoia
victims group changed the time and location of the meetings and no one
will tell me where and when!?...
I fly-cut my instrument holes on my drill press. I used the few
instruments I had on hand at the time and cut all the holes to the
smallest dimensional tight fit.
When the two remaining instruments arrived one of the holes was too
small. After cussing a bit, I used a machinist's de-burring tool to
enlarge the small hole. By doing a few cuts while holding the panel
upright the some more after rotating the panel a quarter turn, a few
more cuts, rotate a quarter turn, and so on I was able to enlarge the
hole fairly uniformly to a good fit. I then went back and de-burred the
remaining holes to allow for painting.
Fortunately for me, I did not find any holes to be way too large.
However had I done so there might have been full justification for
trying to join that damn paranoid club in the first place.{[;-)

Mounting holes on 2-5/8" diameter circle is the standard. This is
consistent with the ACS diagram, Vans 2-1/4" gauges and the drill jig
from Avery. I cannot speak for any other manufacturers.
I have been told there is some slight variation so don't plan to mount
the instruments with countersunk screws.

Subject: | Spraylat removal problems |
Builders,
I used Spraylat as a protective coating for my Lancair plexiglas canopy. It
was advertised as a plexiglas protectant during aircraft construction so I bought
some. It came in a quart-size bottle with no labels, no directions, no warnings,
no Material Safety Data Sheets, nothing.
I read on all the lists just to brush 2 coats on so I taped off the edges of
my canopy and brushed on the Spraylat. A week or so later, I sprayed an epoxy-based
primer over the tape and some primer got onto the Spraylat which I thought
would protect the plexiglas. It didn't. Somehow the primer reacted with
the Spraylat and it made the Spraylat impossible to remove. I thought for sure
it would protect my canopy during the construction process as advertised and
painting is a normal part of the construction process.
I contacted Spraylat who said to soak a cloth in warm soapy water and let it
sit on the Spraylat. No success. I researched the internet and found that Wicks
Aircraft online catalog says, "NOT TO BE USED AS A PAINT MASK". I didn't
know that before I bought it from Aircraft Spruce. So, technically, it protects
the canopy during the construction process EXCEPT for paint.
I have tried everything to remove it. 3M adhesive remover, lamp oil, kerosene,
and the only thing that worked was NOVUS 3. Still, there was 10% of the Spraylat
which was permanent after a solid week of work. I ended up using a razorblade
and then a dremel tool with a felt pad to remove the scratches from the
razorblade. The dremel tool heated up the plexiglas and made small internal
cracks and completely distorted the canopy. Now, my canopy needs to be replaced
- there is no way around it. I was so close to first flight. Now it will
take another year to rebuild it.
So, here is what I learned: NEVER USE SPRAYLAT around ANY type of paint.
I am wondering if anyone else has had this type or any similar type of experience
with Spraylat. Wicks aircraft told me they had heard of that happening to
someone else in the past which is why they added the statement.
Also, is anyone else getting Spraylat in plain bottles with no warnings, no labels,
no instructions, and no Material Safety Data Sheets? I'd really like to
know. I am told that even if I received all of that, none of it includes a
warning that Spraylat is not to be used as a paintmask.
This happened on a Lancair but I am posting this to all the aircraft sites so
that no one will go through what I've gone through and learned the hard way.
I look forward to hearing your experiences and advice.
Please respond to me at:
mattreeves@yahoo.com
I sincerely appreciate anyone else's input and advice.

Subject: | Re: [RV-8] Clearance between oil cooler and engine mount? |
The oil cooler is mounted on the baffle, so it moves with the
engine. I've reworked it a bit to get somewhere between 1/4" and
9/32". There is no way to get much more than that without a complete
redesign of the mounting arrangement. My mount is more complex than
most, as it incorporates a sliding door to control the incoming air
flow. I don't want to redo the mount if I don't need to.
I've had several responses from people who had 3/16" to 1/4"
clearance with no reported problems, so I'm going to try out what
I've got. The cooler is aluminum, and the mount is steel, so I don't
think any contact will hurt the mount, other than damage the paint.
Obviously repeated contact wouldn't be good for the cooler, so I'll
pay close attention to this area until I have some time on the aircraft.
Thank you very much to everyone who responded.

Hi Bob-
I'm doing the AutoCAD panel layout and have contacted a local waterjet cutter
in Nashville about pokin' the holes. Another builder in the area used him
with good results.

Might go to Steve Davis in Memphis who did my previous panel with excellent
results. And the BBQ there is to die for...

Subject: | Light twin for sale |
I am posting this for Ken Coe who is a friend and an RV3 owner. Ken is
selling his twin-engined 1967 Wing Derringer for $125K. This plane is
gorgeous and of museum quality. Ken is the second owner having bought it
from George Wings widow. Only 11 were build and some 6-7 are left. It
seats two side-by-side, has IO320B engines, an empty weight of 2100
pounds with an 850 pound useful load, and a 227 mph cruise. Kens cell
number is 443-7460 with a 925 area code, in Livermore, California
