By you, if you have to ask these questions, then probably not. At
least, not before Christmas, so don't go lying to the wife about why
you have to buy all those tools to make one for her!!
Amateur astronomers have long made their own mirrors. Pick up a
book on telescope mirror making.
Parabolic telescope mirrors have been manufactured for a long
time. Consider the working conditions when this started -- no
central heat, no air conditioning, no lighting other than
candles, but they got the job done. It won't be fast, but you
can do it almost anywhere, even the kitchen. Biggest problem
will be keeping stray abrasive particles [dust] out as you near
Kits are available -- see the astronomy magazines.
Astronomi dilettantistici hanno lungo fatto i loro propri
specchi. Raccolga un libro su creazione di specchio di
Specchi del telescopio parabolici sono fabbricati da molto tempo.
Consideri le condizioni che lavorano quando questo
cominciò--nessuno calore centrale, nessuno aria condizionando
nessuna illuminazione altro che le candele, ma loro ottennero il
lavoro fatto. Non sarà veloce, ma Lei può farlo quasi dovunque,
anche la cucina. Il più grande problema terrà particelle

Maybe. You didn't say how big your garage is and where it is located.
If it is a vacant airplane hanger located in the middle of a large
field, you might be OK.
You need to talk to your local government authorities and find out
what the building code requirements are for such an operation. Here
are a few things that my local government requires:
* Building must be fire proof construction using steel and/ or
concrete * Building must have large doors at either end so that fire fighting
equipment can drive through without having to turn around within.
* Machinery must be placed at least 5 metres away from the nearest
wall and the area kept clean and clear so that fire fighting equipment
can drive in the space between the wall and machinery. * You agree to have unannounced fire inspections conducted on your
premises at least once a month. If any infractions are found, you
will be immediately shut down and may never be allowed to start up
* Your building must have an automatic fire sprinkler system
installed. The water supply to your building must be adequate to
support the sprinkler system. If it is not, upgrading of city water
mains to your premises is at your expense. * Feedstock for your injection molding machinery and any other
combustable material must be stored in a prescribed manner in a
separate standalone building of fire proof construction located at
least 100 metres from the manufacturing facility.
* Any fumes, vapors or odors emitted from the manufacturing process
must be recaputured and must not be found beyond a 500 metre radius of
the manufacturing facility. No other building must be located within
a 1000 metre radius of the manufacturing facility.
HEALTH AND SAFETY:
* Plastic resin feedstock is a hazardous material and fumes are toxic.
You must wear appropriate safety equipment at all times and must have
certified medical personnel on site at all times as a condition of
your operating license.
Why would you want to make it? A Made in China mirror like that
retails for $1.20 and is included as a free gift with the purchase of
$100.00 worth of cosmetics. Around here, $100.00 worth of cosmetics =
one 25ml bottle of perfume and one stick of lipstick. You could
purchase more than a lifetime supply of mirrors at wholesale direct
from China for less than the cost of machinery.
The real cost is not in the machinery but rather in the cost of
compliance with government regulations. What I've outlined above
applies in all cases, no matter whether you have one injection molding
machine the size of a household refigerator or 10,000 of them in a
large factory -- as soon as you turn one on, you become a
manufacturing facility and must meet all FIRE, ENVIRONMENTAL, and
HEALTH AND SAFETY laws that apply to such a manufacturing facility in
your jurisdiction. These laws are usually written with large
factories in mind.
For example, if I were planning to set up an operation with only one
small injection molding machine in my jurisdiction, I would have to
ask myself, can one machine generate enough revenue so that I can
a) A parcel of land large enough so that no other building is located
within a 1000 metre radius of my manufacturing facility in order to
meet fire code regulations?
b) Pollution control equipment to prevent any odor from escaping
beyond a 500 metre radius of my manufacturing facility (pass a sniff
test on a windy day) in order to meet environmental regulations?
c) To pay a licensed medical doctor to be on my premises when my
machine is in operation in order to meet health and safety
In my case, no way! And, if I decide to break the law, I will find
myself being a permanent guest of the government in a large house
where all my needs will be taken care of as soon as my neighbor takes
a sniff of the fumes, vapors, and odors coming out of my residential
Perhaps, the laws are different where you live but, I would check with
the local authorities before purchasing any equipment. The cost of
compliance with local laws and regulations may be many orders of
magnitude greater than the cost of machinery.
Here is a recent example of environmental laws in action:
Can you provide some idea of size and material. ?
Doing a couple of mirrors by hand is certainly possible. It is much
much easier to by a blank and finish the polishing.
If you are doing quantity then you need a lens grinder and polisher.
Cost starting about $10,000 and going up.
