Die grinder at Harbor Freight

2002-04-11 by Steve Greenfield

How 'bout this little thing? Too much weight to put in a plotter,
but maybe in a homebuilt router/engraver.

58,000rpm no load. There is a Harbor Freight Tools about 1/2 mile
from my house.

How are you guys measuring runout? Drill with a stiff bit then
measure the size of the hole? I don't have a micrometer that can
measure the inside of a round hole.
