Bold 3 are going to build a traditional machine. A cutting head, with teeth, will eat its way through the concrete. A spiralling piece of sheet metal will carry the "spoils" (dug through material) away from the hole for a smoother operation. They will use the engine from a vehicle to power a pump leading to...a hydraulic engine connecting to the cutting bit. Their only downfall will be the curse of the hydraulics.

The Turbines are using a machine found mostly in coal mines. A head with 3 sets of spinning teeth to eat it's way through the concrete. It will be powered by a motorcycle engine and pushed physically through the wall by the team. They plan on using 2 chains which should cause the head to pull itself through the concrete instead of pushing against the head to force it into the concrete. Will two motorcycle chains and a motorcycle engine be enough to get through six feet of concrete? The Turbines had better hope so.

The Turbines' dual chain design. Easy work but twice as much to break!	Bold 3s hydraulic auger. It's powered by hydraulics. Is that good or bad?
The Turbines want to use this car engine to power their digger	Look familiar? It's a hydraulic engine & pump in one. It's also seen more use than a collection plate on Sunday
This pump is much more managable than "Yellow Death"	The Turbines are now going to use a motorcycle engine. Much easier to work with in the long run
Judge Darlene Bray	Tyler gives Cathy a surprise
Turbo 3 will use this Jeep engine to power the hydraulic pump/engine	That shear pin will connect the pump to the Jeep's drive shaft
The Turbines' sprocket isn't perfect so it has to be rebored out
