Overview: Rick roasts up a pipin' hot coffee grinder overhaul after a client spies a recently picked 1800's coffee grinder sitting in the shop's boneyard. Can Rick and the boys brew up a perfectly caffeinated contraption or will a little decaf spoil the fun? And later, the shop revs up a collectible 1930's fishing boat motor. Can the guys go full throttle on this nautical tune up or will this high seas speeder sputter out?
