    --> AeroElectric-List message posted by: N5SL <nfivesl@yahoo.com> Hi John: Thanks for the link and the tip. Part number 7529K31 is the aluminum equivalent. Why not use the aluminum chord grip? It's about the same price as the zinc part. Another question - do you need the accessory kit for mounting it to the firewall? Here's some text from the McMaster Carr page: "Temperature range for aluminum is -40 to +300 F; for nylon it's -40 to +225 F; for zinc-plated steel it's -30 to +225 F."

A very good observation. I believe all the usual suppliers carry the appropriate fittings in steel. Also, if you take a look at any fittings that came on your mechanical fuel pump and fuel injection system or carb, I believe that you will see that they are steel. The only aluminum in my fuel system forward of the firewall are the mechanical pump vent elbow and a short piece of rigid tube between the bulkhead elbow and the firewall mounted fuel flow transducer. This, as well as all the fuel and oil hose FWF is jacketed in firesleeve. Also along those lines, Van's hydraulic reservoir is aluminum, filled with flamable liquid, and directly penetrates the firewall. Mine will be liberally sealed to the firewall with intumescent caulk. Probably the biggest offender is the cabin heat box. A SS flapper doesn't do much good when the aluminum box it's in melts off the firewall.... Just another .02!

Lines drop down from a T on the reservoir to the brake cylinders and nothing through the firewall. An alternative would be the reservoirs on the master cylinders (MT-MC5 also from Wicks). Plus, I made a duplicate cabin heat box and door from stainless, and used a steel hinge for the door. There's a complete one available on Doug Reeve's website (I think that's where I saw an ad, but couldn't find it just now), but it was very simple to make using Vans parts for patterns...

    --> AeroElectric-List message posted by: "John Schroeder" <jschroeder@perigee.net> Scott - Yes, you do need the accessory kit for some of the fittings. I don't know why we went with the zinc coated steel fittings instead of the aluminum. I did not register on that info on temperatures. Intuitively, I would have thought that steel has a higher temp rating than aluminum. Perhaps the AL is an alloy that can take more heat.

I find this hard to believe and was about to wire in a standard 3/32nd phone jack but the guy told me you can't get a cable to go between the cell phone and the jack and it won't work anyway. Seems very odd, I mean how do hands free set ups work then? So has anyone wired their cell phones into their audio panels using a standard 3/32nd jack sucessfully? Note I have no intention of using the phone while arborne, just my Wife often likes to make a call just before take off...Don't ask why...:)

There are cell phone interfaces, because I have two of them and they were delivered with my Lightspeed headsets, and they just plug into a regular stereo mini jack, it is the cable that is unique for each model of phone.

    Subject: Recommendations for automotive alternators
    --> AeroElectric-List message posted by: Jon Goguen <jon.goguen@umassmed.edu> We're considering building our own vacuum pad driven alternator set up for a Rotax 912S. (The Rotax external alternator doesn't fit without extensive cowl modifications, and exisiting vacuum pad mount alternator options either have inadequate output due to low rpm of the drive (B&C systems) or have unverified output specs.) The basic idea is to mount a pulley on the pump pad, and use it to drive an external automotive alternator at 2-3 x the pump drive rpm. A 30-40 amp alternator is sufficient, and would ideally be small, light, and externally regulated, although we haven't rejected the internal regulation option. Anyone have specific recommendations regarding the available alternator models? Thanks!

    From: James H Nelson <rv9jim@juno.com>
    --> AeroElectric-List message posted by: James H Nelson <rv9jim@juno.com> Jon, Get on the Europa e-mail list, I designed and built a direct drive for a 40A alternator that ran off the back side of the engine (912S). I built an Europa mono wheel and wanted more power. I gave my drawings and instructions on how to do it to one of the guys who copied mine. It takes a bit of time but it all fits. I used a IFIR (internal fan, int. reg.) automotive unit that bolted up to the crank at the flywheel. Used a B&C regulator as I modified the alternator to a "B" lead config. The alternator was coupled through a sureflex coupling 3S size (only Martin sprocket and Gear will work) for the emergency sheer point. Ran great. I had mine for two years and 85 hours of trouble free useage. Can be done but requires time and machine work on the mounting plate ect. Jim Nelson

    --> AeroElectric-List message posted by: "RV Builder (Michael Sausen)" <rvbuilder@sausen.net> If I had to guess I would say the difference is in the failure temps of the gasket materials. Because aluminum conducts heat much better than steel, there is a good chance the nylon/rubber/whatever will stay below it's melting/flash point longer thus the higher temp rating for the aluminum.

    From: "RV Builder (Michael Sausen)" <rvbuilder@sausen.net>
    --> AeroElectric-List message posted by: "RV Builder (Michael Sausen)" <rvbuilder@sausen.net> I would think the easiest thing to do is put a standard size jack in, doesn't matter what size just pick one that has enough connections (3?). Then depending on the type of phone, as many have different plugs anyway, you would just have to take a standard handsfree cord for that phone, chop the earbud end off and wire it to the mating plug for your standard jack.

    From: "Greg Young" <gyoung@cs-sol.com>
    --> AeroElectric-List message posted by: "Greg Young" <gyoung@cs-sol.com> Most, if not all, cell phones now use the same earphone jack and wiring. Nokia used to be an oddball with a 4 section plug but they switched over a couple years ago. Use the same mini-jack as your phone and use a straight thru patch cord. Stark should have labeled the wires (ringer, phone & mic IIRC) and should know what section of the jack each goes to. Greg Young Ps - my audio panel supports a phone but the connection thru my Lightspeed 30-3G is just too convenient to fool with it.

    Subject: Re: Firewall penetrations
    --> AeroElectric-List message posted by: "Richard E. Tasker" <retasker@optonline.net> I believe the rating has more to do with the insert than the body material. These parts have an insert of some type that clamps onto the wires when the grip is tightened. We use similar parts at my company and you can get all sorts of inserts that have temperature ratings all over the map. The bodies are not the limiting factors, with the exception of the nylon one.
