Nuckolls, III) ________________________________ Message 1 _____________________________________ Time: 12:16:13 AM PST US From: "John Ciolino" Subject: RE: AeroElectric-List: snorkel for alternator cooling Here's what I did: ACS sells a 1" aluminum flange (p/n 10350-4). Drill a 1" hole in the inlet ramp and rivet the flange in place. If you are good at bending aluminum tubing also order some 1" tubing and you are all set. I tried that and couldn't get the tubing bent without kinking so I used some 1" SCAT tubing. To keep the tubing in place I took a strip of flat aluminum, bent it to direct the tubing to the alternator and attached it to the flange with a hose clamp. I attached the tubing to the aluminum with tie wraps. Good luck.

My RV6 has no alternator cooling other than the (reverse rotation) internal cooling fan. I'd like to install a snorkel to capture some cooling air at the air inlet ramp and lead it (tru a hose) to the rear of the alternator. Does anyone know of a source for these little alum. snorkels? I have no means to weld, braze or solder alum. I guess that I could make one out of an old tin can, but that's kind of tacky.

Feeds from inlet ramp on that side down to alternator and haven't had a problem with it, flying about 4 years / 310 hours or so. The tube grooves and a little rtv have held it in place without issue. Light, easy, and inexpensive. Chris On Aug 17, 2012, at 7:42 PM, Kelly McMullen wrote: > > I wouldn't recommend it. It is nylon material IIRC.

I didn't perceived he was talking about an LR3C-14, of course he would need the -28. Thanks!

Also, look around your favorite auto parts store for a pre-shaped radiator hose. john On 8/17/2012 7:42 PM, Kelly McMullen wrote: > > > I wouldn't recommend it. It is nylon material IIRC.

I had the same concerns as you because I have a plenum capturing all the cooling ram air and directing it through the cylinders. My engine installation is battery/electrical system dependent (fuel pumps, EFI & ignition) so I wanted a little insurance for my reversed-fan alternator. I fabricated the alternator diode plate plenum in the picture from fiberglass and vinyl-ester resin. The resin will withstand 220 deg before going plastic. Epoxy resin systems will also work. Just check to see that the transition temp meets your needs. You can use the stamped cooling shroud as a mold for your part. Connect to ram air source with SCAT tube size of your choice. I used 3/4".

Bob N. Thanks for your explanation. No, nothing special about my alternator installation, N-D in the standard position for a Lyc. I was only concerned because someone who had done the cooling duct on an RV6 was concerned because I had none. I thought better safe than sorry.

I have one of the quality wire strippers from B&C, but it only strips up to 16 awg wire. How do you strip larger wire. For example, I need to strip some 8 awg wire for my power runs. Is 8 awg stranded wire bigger around than 8 awg solid wire?

I don't have tools for stripping anything larger than 14AWG. All the big stuff I just score carefully with the ol' Swiss Army Knife and use a pair of diagonal cutters to pull of the discard. Do a few practice strips to get the hang of it.
