Perhaps the 16GB iPhone 4S would be a suitable example. It costs
about $200 to manufacture, but sells retail for $500 from various
vendors, or $650 from Verizon. Using the $500 sales price, the cost
of shipping an empty iphone box is:
$500 - $200 = $300
The $300 pays for everything EXCEPT the product. For Verizon, 3.25
times cost is rather low for electronics. 4.0 to 4.5 times cost is
more typical.

this has to be a joke. If you're not from NASA, it's got to be lehman
brothers, enron or arthur anderson to say with a straight face that it
costs $300 to ship an iphone because the retail price is $500 and the
phone costs $200 to make.

Quite real. The $300 difference between the retail price and the cost
from Apple is a conglomeration of profit and expenses. The profits to
Verizon and its stockholders. The expenses are a mixed bag of
executive compensation, sales incentives, advertising, taxes,
packaging, shipping, distribution, documentation, support, shrinkage,
returns, repairs, political contributions, debt retirement, assorted
bribes, charitable contributions, publicity, lavish product
announcement parties, slush funds, ad absurdium. If you think you can
So again, stating it costs $75 or $300 to ship an empty box is just pure
bullshit.

The symptom is when you maually engage the bobbin winder assembly on the top
of the machine and press the button to activate it, you can hear the motor
turning inside but the winder does not turn. The first two photos show the
faulty drive assembly removed from the machine. The last photo shows the
assembly loosely installed in the machine. There is some mysterious black
slime (could it just be lubricant?) which I thought must have been some kind
of belt or idler that started disintegrating from age but the machine is
only about 5 years old. The main belts are in very good condition so it
doesn't make sense to me how this could have happened. If you poke the slime
with a small screwdriver it doesn't make a really big mess on everything it
touches like an old rubber belt does. You can see in the third picture that
the area surrounding the part is fairly clean. I think that small black mark
on the large gear to the left happened when I removed the part. By the way,
the part in question is mounted on a plate that can be manually shifted up
against the main gear assembly to get it to turn. I searched around for a
parts diagram for this model but no luck. I know some of you that frequent
this board have delved into sewing machine repairs and was wondering what
this part is and how it interfaces with the drive mechanism to make the
winder rotate.

Thanks for your reply.

This is awesome! I have a similar problem with my brother cs-80 and it is great to find this. Thank you so much, this is super helpful. I just ordered a new tire ring for my machine, which also melted, now I'm just waiting for it to arrive. :)
