Fascinating. <br>

I'd like to add one additional warning about those chemicals. <a
href="http://en.wikipedia.org/wiki/Flammability_limit">Acetone</a>
will ignite at twice the air/fuel ratio of gasoline and it's very
volatile, so at higher temps like described in that how-to it might
be possible to set yourself up for something extremely unpleasant
with an open flame or spark in the vicinity. A very, very good mask
would be a given, of course. But the hydrochloric acid/peroxide
mixture made my hair stand on end. I didn't read must past that, so
I don't know if they call for heating that mixture...<br>
<br>
Around age 11-12 I was casting zinc/sulfur solid rocket propellant
and doing other insanely dangerous things. But now days after
reading this the hundred dollars for a stainless steel stencil seems
completely reasonable. :-)<br>

<div>Here is the article I mentioned last night about making
metal paste stencils. I do not recall if this has been posted
here so I thought I would post it. I am enjoying many of the
projects at LowPowerLab.
