Well, the wife wanted me to pick up another USB thumb drive, well I ended up getting 3 different sizes of Channel Locks for work, 2 boxes of Cheese Its (smoked provolone, and baby swiss), can of smoked oysters, box of garlic club crackers, and a brick of cheese.
The magnets in that head pulley were damn strong. It pulled my tape measure off my pocket several times, pulled a wrench out of my pocket (none of the wrench was sticking out). But out of the 4300 pounds for the entire deal (pulley, shaft, and bearings) 600 was in the bearings, and ~500 was in the shaft, so roughly 3200 was in the pulley itself and the housing for it all was cast aluminum so I am guessing there is probably 2000 pounds of magnets in this thing. And people worry about magnets in money clips killing debit/credit cards.
