Do you have one of these machines?
It's almost mesmerizing watching these lasers clean rust off metal. Until this video I didn't realize it was safe to put your hand in the beam. This looks a lot easier than the old elbow grease method.
Unfortunately, these machines are prohibitively expensive currently:
Here's
one
for only $45000 (200W)
Luckily,
there are versions manufactured in China, like this one
for only $17500 (100W)
