Carter contemplates the ideal drill-powered comfort-mobile.

Julianna works on a color-coded specification for her team’s vehicle.

Less than 24 hours after arrival, the Boys’ Room is clearly… the Boys’ Room. It also has space for the spare furniture, so doubles as the hang-out room.

After lunch, the teams get serious about getting their vehicles moving. Gus appears to be in a bit of a post-lunch stupor. Maybe he’s just trying to remember where he left his safety googles?

Sam is either preparing to mark the cut lines for the fancy triangular platform for their car, or banishing the demons from this place.

In order to have wheels turning, you need axles. And to put axles in wood it’s great to have some holes. The teams line up for their turn at the drill press. Piper favors the cross-handed technique. Leo is fascinated by this.

Liz reviews best practices with Anna while Fiona checks the measurements for the Harley-style steering fork.

Robyn has warned her team that they are using a slightly exotic configuration for the chop-saw. Theo grabs Carter to remind him that safety goggles work better than karate chops when defending yourself from flying sawdust.

Sam’s ghost-busting appears to have worked, as he is graced by the heaven’s above as he prepares the drill for cart-mounting.

Elena checks the fit of the drill mount while the rest of the Piki evaluate.

Gus is building a protective cover for the overly long axle bolt. Gever agrees to try chopping the heavy-duty cardboard beam on the chop-saw, which creates voluminous clouds of paper dust. Gus is not impressed.

Nik’s fancy fly-fishing sunglasses work great as safety googles – often he is the only one with a clear view of the work area. Nice power-driving technique – those 5 years of Tinkering School are paying off!

Julianna’s fancy reined steering system has been embraced by her teammates. She gives it a pep talk.

The littlest tribe fortunately has the littlest vehicle so that they can transport it to the test track without assistance.

Who gets the coveted first ride on the first vehicle to be drive-tested? Scissors (Elena!) cuts paper.

The Piki are eager to see their cart fly across the barn. Locomotion occurs, but the tendency of riders to grab the tires/drills results in a revamp to add fenders.

Anna’s lost suitcase still hasn’t arrived, but she insists she isn’t just showing off wearing white and avoiding being covered in dirt and sawdust. Here she demonstrates her dainty (yet effective) clamping technique.

Carter has christened their cart “The Meteor” and is decorating one fender to that effect.

Gever agrees to go say hi to the llama, since the rest of us are afraid we’ll be spit on. He actually manages to pet it, but we were all really hoping he’d get spit on again so we could see it this time.

Gus prepares the second fender for The Meteor.

Leo has been practicing his drilling and power-driving technique all day. Luckily he is just as good at extracting screws as he is at installing them, or all the tables would be covered in 2×4s.

Elena and Carter assess their finished fender. It looks good both coming and going, says Carter.

Sams acts aloof, but doesn’t fool Theo.

Steve demonstrates his stealthy approach to getting great casual shots of the teams.

The carts are nearly finished, and decoration activities are in full swing.

Anna confirms the seat attachment plan with the Little Boss.

Julianna and Piper work on the front and back plates for their vehicle.

Carter pre-visualizes crossing the finish line first.

Not only is it comfortable, the Kablooi cart really moves. Sam looks like he can hardly believe it (clearly Anna never had a doubt).

Anna shows her typically restrained reaction, while her teammates try to contain their excitement about seeing the cart finally work.

Fiona finally cracks a smile when the cart finally maintains its momentum (thanks to a double-sided tie-down system).

The typical problem with the drill-powered cart design is getting sufficient friction on the wheels. The Nooi solution using rubber covers on the drills isn’t holding up, so modifications are in order.

Julianna’s rein-style steering isn’t getting a workout yet, but her trusty steed has taken off at last.

Nikhil uses every ounce of effort to push the drills against the tires in order to get the cart to move. Some sort of assistance device might be in order.

Anna and Julianna make quick work of the first thing they grab out of the bin.

Sam can’t quite believe he’s been told to completely disassemble this drill. He decides to make sure he heard it right before doing anything extreme (for a change :-).

Piper has also tackled drill dissassembly, but like everyone else, she is slowed down by the barrel. Unlike everyone else, she manages to pry it apart using the vice!

Nik and Elena team up – that thing (whatever it was!) doesn’t stand a chance.

Elena volunteers to help carry some sawhorses back to the ranchhouse. Robyn agrees to stack them up as requested, but Liz isn’t so sure about that.

Several of the kids insist on helping to carry the plywood back to the ranchhouse. The parade makes it half-way there before tradeoffs are in order.

Julie and Theo head to the hill. The sheep are curious, but frightened, but curious, but frightened. They can’t decide whether to watch or flee.

Theo tests the model glider he built during his spare time today(!). The sheep decided it wasn’t interesting enough so they left. Maybe they’ll be back for the updated version tomorrow (needs wider wing-span for better stability, says Theo).

First cart test-run. First Piki driver. First gear = reverse!
