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

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. -Brad https://lh3.googleusercontent.com/_n09BC0F4KSY/TZqG5mEWEZI/AAAAAAAAABE/G0SpRaIat2c/IMG_2433.JPG https://lh5.googleusercontent.com/_n09BC0F4KSY/TZqG6dvV64I/AAAAAAAAABI/zLfDlnavK8M/IMG_2432.JPG Hope this helps!!

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... -Ben -----Original Message----- From: owner-rv10-list-server@matronics.com [mailto:owner-rv10-list-server@matronics.com] On Behalf Of rvdave Sent: Tuesday, October 21, 2014 2:34 PM Subject: RV10-List: Firewall penetrations I'm at a standstill trying to decide how to get bundles of wires through the firewall.

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.

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. http://youtu.be/NtqXlOX_kF4 You will be pleased. I promise.

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.
