Hey there, I’m building a concrete nipple/pump bump at my house & figured I want it symmetrical so constructed a crude rotating aluminum pipe screed, figuring it should all work in theory but wondering if anyone done anything similar & of any problems in doing it this way. Pouring it this weekend so figured I’d put it out there for any useful hints or tips. Thanks Check it out on Backyard Skatepark

We went to the new skatepark in Happy Valley, Oregon last night. This detail of bizarro Rich captured in panorama mode actually does a good job of representing our disjointed session there. Not visible in this shot are the 30 some odd kids roaming the perimeter. Imagine your entire peripheral vision filled with kids on skateboards, scooters, wiggle sticks and bikes, all about to run into you. It was pinball city.

This time around we have something known as a “Protuff” skateboard, and apparently this is #5. I’ve never seen the Protuff brand, so I would have assumed it was some sort of European equivalent to Nash or Variflex, but this auction came out of Florida. As is sometimes the case with these toy store boards, there’s more than meets the eye here. The Grim Reaper comes complete with some of the oddest looking plastic trucks copers you’ve likely ever seen.

Be sure to have some extra Euros with you when skating in the wrong places in Barcelona, Spain.

For all the talk of patents, squares and radical new design, when you look at this wheel in profile, it’s still a circle. So essentially, the only thing different about this wheel is that the grooves are zigzagged. Grooves in a wheel, even on a skateboard, are nothing new. The wave pattern may be new on a skateboard, but look at your car tires and you’ll see a more intricate version of the same thing. The main advantage they can claim is more speed from a reduced contact patch, but then again any grooved skateboard wheel already has that. However, just like a car tire, these grooves should provide better traction in rain and dirt. So they look different, but at their core, they really aren’t very different at all from traditional grooved rain wheels. Let the science fight begin! The inventors of the Shark Wheel have been pouring their own prototypes in a garage, which is pretty cool, but of course there’s a Kickstarter project to fund mass production. Even if mass produced, these wheels will probably have to be offered at a premium because the molding and finishing process is going to involve more labor than the old…
