G'day all,
I am about to work the firewall for wire and cable pass throughs. What penetration techniques have people found the best - eyeballs, s/s grommet covers, tube/firesleeve etc?
Are there any specific locations to avoid when making the penetrations? Is there a 'best spot'?
What is the best way to cut 'largish' holes (ie >1/2") into the stainless??
Thanks in advance for your suggestions.
Ron

Ron,
I used aluminum eyeballs for everything, it made getting the alignment a snap. I filled the aft pocket of the eyeball inside the cockpit with high temp silicone. I use a greenlee punch to make the holes, you drill a 3/4 hole with a unibit then use the punch, works great. I'll fwd some photos and shoot them out to you. I used the three triangle stacked in the recess for power, rpm and mixture. I use the upper left firewall for the purge control and low in the tunnel for the FAB aux air door. I also used the eyeballs for my battery and alternator lead penetrations. Granted these are a bit pricey, but they look good, allow for the cable to exit the firewall at it's best angle. The only thing that was a pain, not hard but time consuming was drilling out the balls for the cables or wire with the drill press.

Every RV builder should check out EPM-AVCORP.com before they start working on their FIREwall. Regardless of which way you go, you should have the information. This guy has done the research.

I really liked these for all my wires. Just order the biggest one if you go this route. The smaller ones are much more difficult to work with. I used the eyeball style for my throttle, prop and mixture and for my three cables that power the electronic ignition.
