I did chemistry up to tertiary level and my father was a Canadian
trained chemist...He is now blind in one eye and cannot smell AT ALL due
to constant exposure to these very same type of hi volatility chemicals.
My first job as a 'sales' engineer had me going to Paint companies to
promote filtration. The techs washed their paint smeared hands daily in
a concoction full of aromatic rings..benzene,xylene, toluene; acetone
was always there as well.
After working for a week with them I started to have problems smelling
things properly as well. I left that job.
My fellow hobbyists, you must be aware that frequent exposure to that
volatile stuff WILL penetrate your skin and breathing it in will get it
into your system. Don't compromise your long term wellness for a bit of
convenience. These chemicals are also a serious fire hazard and do not
mix well with nearby mechanical/electrical experiments creating little
sparks when prototyping or metal working. Even the internal arcing from
a Dremel drill can ignite a nearby open acetone bottle or solvent damp
paper towel. It may not happen the first 50 times you do it, but it can
happen anytime and once is enough to take out your lab.
I always wear safety glasses when dremeling, once when cutting off a
6-32 screw the cut piece shot straight into the safety glasses and
ricocheted off before I could even blink. Once in many years, but that
once would have cost me an eye without due care.
Use HP generic toner and one pass hot lamination guys...no fuss, no
muss... no long term risks.
This is how I do it...down to better than 10 mil accuracy.
