Yep! My drawings were inside the FAB along with all the other parts.
Not sure why they were separate from all the other drawings.

I'm at a standstill trying to decide how to get bundles of wires through the firewall.
I purchased the swivel grommets from Vans and after reading reviews of
galling, bending, and almost ready to bore large holes--am not committing to
that process. First of all how do I get a large hole over 1" through the stainless?
There must be a tool I haven't seen yet. I have ruined many bits drilling
through the stainless in the past until I realized slow speed and lube is
your friend. Second I know there are better options out there I believe, just
not sure which I'll use yet. The cut off stainless door handles are pretty
witty. The rectangular from Avery may work well also. Some have welded their
own tubes--i dont quite have that talent. Anyone to share photos and experiences?
Also tips to make hole in stainless firewall? Thanks

Option #1
You can go to the aviation isle of your local big box hardware store and purchase
a stainless bathroom grab bar (handicapped accessory). You cut the ends off
and leave about 4inches of straight tube on each end. For $20 you will get 2
elbows with a flange that would cost you hundreds from aircraft spruce. I will
post a link to pics for this option later.
Option #2
(Taken from VAF forum page http://www.vansairforce.com/community/archive/index.php?t-57730.html )
Here is what I did. I bought a steel contuit junction penetration at Home depot
and fit it to the firewall. They sell them in 1/4" diameter increments. I added
a 2nd nut to act as a jam-nut. On the engine side I added about 5" of firesleeve
with a steel band to keep it tight. I also added the set screw back inside
the conduit part to prevent the steel band from slipping off. I have to give
credit to my EAA tech rep Deene for the idea. I'm able to fit all three control
cables plus my EI coaxials though this point. I'm not flying yet, but it looks
to be a good solution thus far.

A "Knockout Punch Kit" works pretty well. Harbor Freight has a cheap set
that is adequate. Decent brands are several hundred dollars so the HF ones
are the way to go since you probably won't ever use it again.
http://www.harborfreight.com/knockout-punch-kit-91201.html
I think most purchase a firewall pass thru kit from spruce or various online
sites
http://www.safeair1.com/averytools/firewallpassthrough.php
http://www.aircraftspruce.com/catalog/elpages/firewall_penetration_kit1in.ph
p?clickkey=10735
You will want 2 of them and I think most get the larger 1" size assuming the
plethora of engine monitor wiring...

I feel your pain .... from the many cuts by the SS.
Right or wrong, here's what I did.
I drilled a 3/16" hole and enlarged with a step drill and various dremel
bits to accept a plastic grommet. I have a MGL RDAC on the firewall to
take all the various engine sensor wires so I really don't have a whole
lot of wires going through the firewall. Haven't finished under the cowl
yet but I'll put a liberal fillet of fireproof sealer around the bundle.

| Subject: | Drilling Stainless |
I've experienced great success utilizing the technique in this video. Basi
c bits, water, and a chunk of wood to backup the stainless as I drill into i
t.
Super crisp holes, no burrs, no pulling of the steel by the bit. It's reall
y really worked well on small and large holes alike. I don't fear (or hate
) stainless like I did before.
You will thank yourself for spending 8 minutes watching it. The only thing
he doesn't point out is the wood he uses to backup his drill bit. I just u
sed a scrap 2x4.

You will be pleased. I promise.

Dave, I went the home made route. I bought a piece of 1" dia, SS rod,
drilled/bored it our to 3/4" ID (I have a metal lathe) and then had a
welder attach a 1/16" mounting plate/flange. I made 2 large pass throughs
for the wiring and 4 smaller others for the control cables for just under
$100. Besides being a bargain compared to other options you can purchase,
they are good solid and fire proof compared to Van's suggested pass
through.
Just another data point [?]
