Wouldn't that burn your hands?

Ed, I am disappoint. You had a perfect opportunity to post an illustration, and you failed.

If you've not read this already:

"If you've got a little bit of hair on your legs it will turbulate [sic] the air so you get a better flow. Now this in itself creates friction, so you don't want all your leg hairy you just want two thin strips, each about 10mm wide, just before the sides of your legs – though you will look really stupid.

You need the turbulent boundary layer – provided by these strips of hair - to get the air around the corner, and you need a smooth layer for it to flow over. But the leg is such a rubbish shape that ideally you want an aerofoil on the back of it." Mike Burrows

I wonder what he thinks about the moustache.

And Xav took him at his word

Looks like a horny penguin draping its balls over his head in reverse cowgirl position.

strong look.

turbulently stylish.

PolkaD I'm going to totally copy you... I hope you don't mind?

is this the same helmet?

Soon we are going to need a HMSH thread. (Home Made Slave Helmet)

Before I made this helmet I did spend some time looking at existing designs on the internet.

I remember seeing some that leave the rear section open at the bottom.

It was quite obvious to me that leaving the bottom uncovered would greatly reduce the effect, so I made mine enclosed.

could you use it as a mandolin potentially?

With a minor mod, this would work for "yard of ale", post-TT, PB celebrations.

Just a thought.

please don't leave your bottom uncovered

Teaser:

at least if you have a mid-TT mechanical and are waiting for the broomwagon you can do a bit of the crossword to keep yourself entertained.

And Xav took him at his word

The price of a PB thankfully most of us are unwilling to pay.

looks like prince faquuuar from shrek.

Is that ^^ an inflatable aero helmet?!

+1 for Polka dot's granny carpet

-1 for wool penises. Why did you have to go an lower the tone

Maybe cut the end of it off a bit so it isnt quite as pointy? that point will wave about with the slightest head movement and disrupt the air.

could cut if off and glue a piece of cardboard in A la http://brimages.bikeboardmedia.netdna-cdn.com/wp-content/uploads/2012/06/2013-Specialized-S-Works-x-McLaren-TT-Helmet01.jpg ?

^ Doubles up as a back scratcher, obviously.

I think there's more going on with the Spec/McLaren than a simple Kamm tail

can't someone just 3D print it

Strong, light, cheap... when it comes to 3D printing, you can only pick one, and 'cheap' actually means 'remortgaging not essential'. Shame, because it is powerful fun. If PolkaDot would like to 3D print it, I will happily create the mesh files for a massive fee.
