That's 14.2 START UP amps. That's how much current the thing will draw as it first fires up. No way in hell that thing is gonna pull 14.2 amp continuously. At that price, with shipping, you'd be better off ordering a "real" buffing machine from your local tool supplier. I got a 1 HP buffing machine for $130 that has 12" shafts off each side and it takes all of my 225 lbs pushing on it to even remotely bog it down. I think it pulls about 6 or 8 amps when running.
What's your preoccupation with gigantic wheels?? A 3600 RPM buffer and a 19 inch wheel will net you a surface feet per minute speed of almost 18,000. That's WAY more than you need to polish aluminum. A 6" wheel on a 3600 RPM buffer will net you a tick over 5600 SFPM. A tad higher than the "sweet spot" of 5000 SFPM, but you'll hit that as the wheel wears down. With a 6" wheel, parts don't heat up so much they're hard to hold, the inertia of the wheel won't rip the part from your hands when you catch an edge and it won't fling cr@p from here to Taiwan when you're buffing.
From the pics you posted, I don't see your need for anything larger than a 6" wheel.. Going bigger won't necessarily get your parts done any faster and could introduce more problems.
