like the silversurfer. i would like to ride it
Yeah, I caught that too.
Anyone know the designer?
Hollow aluminum? I bet it goes BONGGGGGGGGGGGG when you bounce it off of your buddy head on a cutback. I hope it's not too shiny? some of my favorite lures are shiny polished aluminum, Mako just love them!
lets test this silver surfeer unit in highly charged envirunment before the coming thunder...lightning would make this conductor a real shocking advancement in techknowledgie ZOW POP BAM holy semi conductor batman a little electricity and this board does high voltage aerials...ambrose... chasing twisters in a high altitude jump plane...where's Laird?high over Kansas

Oh man....how the devil would you fix the thing?
Funny, though, I have a 26'6" x 12" aluminum rowing shell with composite framing in my front yard just now, which is being repaired ( somebody dropped the tail and bent it) with auto body hammers and forms, very gently applied, some epoxy/EPS framing to be made and installed too... and that involves having accerss to the inside of the hull.
A ding on one of those.....you'd have to set up what, a vaccum arrangement to suck the ding back to a ( roughly approximating the right shape) formed female mold?
For that matter, if they are forming aluminum, it has to be pretty soft aluminum. Annealed, though maybe the process work-hardens it some. Still, how is that going to get along with salt water? I mean, we're talking about a skin 0.02" ( 0.5 mm ) thick, just a little corrosion is going to have some real interesting effects on skin strength.
I'd love to see how they make 'em, though.....
Super Plastic deformation allows you take a sheet of lets say aluminium at an elevated temperature and specific strain rate and extend it to almost 1000% of its original dimensions. I've seen almost 8000% with some Al alloys. The combination of elevated temperature and strain creates low flow stresses and high uniformity of plastic flow in the grain structure of the metal alloy. The result is low density, good mechanical properties, and a high corrosion resistance structure. And it will be a pain to fix.
To make it they simply use a one or two sided die and place a metal sheet over it, heat it up, and apply gas pressure to the surface of the sheet.
This is an expensive process as the Al, even if it is normal Al, needs to be processed to death to get it to behave this way. Interesting application though.
