Norm - Last year I bought five Chinese 1/2" angle grinders on sale from
Harbor Freight for $15 each. I bought so many because I expected them to
fail soon but a well-made Western tool can cost ten times the Chinese
units. I like to have several grinders with different wheels so I don't
have to keep changing wheels. It turned out the only failure mode so far
has been that the switch failed or a wire broke in the power cord near the
motor. I ended up bypassing the switch and installing a cord switch on the
power cord. In the process I discovered that the wires often broke easily
inside the insulation so I know I will have to buy some new non-Chinese
power cords. I have powers tools from Western manufactures with cords that
have lasted for many years so it is my view that the Chinese copper is in
some way defective. My point is that it appears that some copper wires are
more equal than others (sorry - I couldn't help myself!).

Long Version: I saw a little of "Jay's Garage" TV program. The camera
moved in on Jay and his chief mechanic peering into the engine compartment
of an antique Bentley. "Hi there." says Jay brightly, "We have here an
English vehicle with an electrical problem. So what else is new?"
Short Version: Q - Why to the Brits drink warm beer?
A - Because Lucas makes the refrigerators!
