Helmet wind break
Posted: Fri Sep 27, 2013 9:58 pm
Now this is BRAND new :-)
I have found a cheap, simple way to keep the airflow from following down the
face shield curve and end up hitting me right at the nape (?) of the neck - when it's
50 or colder, that gets miserable in short order, no matter how tall of a collar on
my jacket.
Discovered it when I raised my hand to wipe a big bug splatter off the shield.
Just out of curiosity, and for probly the 1,000th time over the years, held my hand
up to see where the airflow was hitting my helmet. I don't have a real tall windshield
so the wind hits me about at the top of the face shield. You'd think all the wind
would just bounce over the top of the helmet, but some of goes downward.
I happened to move my hand downward sort of following the air flow and when I got
it just above the base of my full face helmet, noticed the wind quit hitting me at the
base of my neck. Curious to the last, I tried holding just a gloved finger there, and
got the same result.
As my helmet has about 75k miles on it and is getting a little scruffy anyway, I didn't
feel bad trying something. I ride at temps down into the 30's so am always open to
something that lowers the misery factor. Sooo - went to Lowes and looked for some
cheap stick on foam weatherstripping just to give it a try. Thickest I could find was some
round 5/8" diameter foam backer rod, which was tough to glue onto the helmet as I
feared. But it lasted long enuf to prove that it works! So went back and got some
1/2x3/4 typical black stick on weatherstripping. Had to glue it on with some Loctite
Super Glue so it stayed. Helmet is black and silver so isn't TOO awfully obtrusive.
I purposely held it up about 3/4" above the bottom edge of the helmet to allow room
for some small screw in snaps, or velcro, to attach a piece of fabric that extends down
about 6" and goes around about the front 1/2 of the helmet that I can tuck inside my
jacket to protect the underside of my chin and anything my jacket doesn't cover. Even
without direct airflow (blocked by my weatherstripping), it still gets cold on bare skin
so I have my wife making a little flap out of some thin but windproof fabric or vinyl
(whatever she has in her fabric stash) that I can attach in cold weather and remove in
summer.
I think holding it up even that little bit higher than the bottom edge of the helmet
required a little more sticking out to kick the airflow out away from my neck.
The airflow now hits me about at the top of shirt pocket level, where it's totally
covered by my jacket or whatever. Admittedly a side wind (more than just a breeze)
reduces the effectiveness and makes the "dead air space" a little smaller, but it has to
be a pretty strong crosswind before it doesn't protect that sensitive spot that's hard
to cover.
I'll try to post a couple photobucket pics sometime soon and link them here.
Yes, doesn't look "chic" but I'm already riding in temps down into the upper 40's
in the higher elevations in the Mojave Desert just across the CA border SW of Vegas
at 4:30 am and the elimination of that cold spot makes it well worthwhile. I'm sure
some of you more savvy craft types could come up with something that doesn't look
cobbled together.
Cheers!
