Cliff,
If you have an Aircraft Spruce catalog, on page 92 you'll find the
dimensions of the AN washers. Go through the washers until you have one of
each type, then measure them with a ruler, micrometer.... Tape them down to
a piece of cardboard and label each one. After you sort out the bag, hang
the sample on the wall or keep it on the workbench for reference. You'll
only have to do this once. I keep a copy of all of the AN rivet, bolt and
washer dimensions hanging in my shop. You can find the charts in the A/S
catalog, as well as several other catalogs.
Just note that some of the washers come in the standard thickness and a lite
version (1/2 the thickness). Van's doesn't seem to make any callout as to
which to use, so it's your call.

--> RV7-List message posted by: Chris <chrisw3@cox.net>
Does anyone know why Van's redesigned this part of the plane? It seems
like it is harder to build that way from what I have read so there must
be some advantage to the design over the old one. And if it is better
there why not for the Elevators?

They needed a bigger rudder for the 7 to meet spin specs and just took the
9's rudder and put it on the 7. Now why is the 9's different? Idoknow.

I don't think it is necessarily any better but it is cheaper for Van's
to manufacture. I would think that replacing the manual bending
operation with an extra automated shearing operation would save them
money. On the RV-9 the elevators use the same new method.

It's quite easy to tell a 3/16 #3 from a 1/4 #4. There are only a few
different callouts per size. Thin, reg and large diameter.
You will soon start sorting all of the bags into a system of little bins.
The hardware stores sell cheap plastic containers with dozens of small
bins/drawers. Put all the #3 washers in one drawer. Put all #4 washers in
another drawer. Do the same with the bolts, nuts, rivets, ect. Sooner than
later the bag system will frustrate you. Once you re-organize you will be
set up for your many years of aircraft owner ship. Maintenance and building
is easier when you can see at a glance what you have. Most builders end up
using this system. It's what the factories and repair shops do.

Scott Trask,
Just use a good quality automotive sealer, and that should be fine. Don't
use any rattle can stuff.
Happy Building,

For those interested in non-Lycoming engine options for their RV7s, the
following is the latest intel from the Jabiru factory on their J6000 engine
of 200hp.
a. the first prototype engine has completed 150hrs of flight testing.
b. A second prototype, with improvements, is under dynamometer test.
c. The first batch of 10 engines will be produced in March 03.
d. RV6 then RV7 firewall forward kits will be available shortly
afterwards.
e. The FWF kits will include a completely new engine mount and cowling.
The engine is supplied with integral plenum and exhaust, starter,
alternator.
f. The cowling will not have the typical Lycoming air intake scoop.
Carburettor intakes will be NACA scoops on both sides of the cowl, aft,
fairly high.
g. The oil cooler will have a small intake under the spinner.
h. The price of A$25,300 = US$13,915 was described as approximate, to
be finalised in the initial production run. The FWF kit is unpriced as yet.
i. The integral alternator is permanent magnet, but is externally
regulated.
j. It can only have fixed pitch or electric constant speed props at
this stage.
Have fun, David Francis, VH-ZEE
