Don & All, There are two issues here. One is equipment. I repaired
equipment for resale and business for about five years. In that five
years we saw almost every type off breakdown you can imagine from
every type manufacturer. Most of the breakdowns were attributable to
poor design of the machines or to making the machine to sell at a
certain price point. Even my own shop equipment breaks down. I use
a multistation grinder made by Raytech - “the Green Monster”. My
machine runs about 8 hours a day. Up and down all day, changing
wheels and grinding belts. I cut about 150 custom cabs a week. Most
of these cabs are 30-60mm and fully polished on the back.
When I say the machine is not made for a professional lapidary I say
it for two reasons. One is that the machine is not comfortable to
use for long periods of time. The wheels are too close together and
there is not enough room to comfortably rest your hands. Lighting of
the grinding area is a problem as the frame of the machine blocks any
lighting I have tried to make. Coolant feed reliability is always a
problem. The pulley that runs the arbor is not centered on the arbor
creating unbalanced stress on the bearings which cause one bearing to
wear out faster than the other. I change my bearings about every 6-9
months. This is a good machine, but not what I am looking for in a
professional machine which is why I am going to look at the machines
made for the optics industry. If they fail to have what I am looking
for I will make my own grinders.
The second is professional versus hobbyist (amateur). Professionals
are described as people in business. People in business abide by
laws and ethics. Everyone not in business is a hobbyist or amateur.
Yes, hobbyists make some very good products, but they are not
professionals.
Professionals in gem cutting come in three categories. The gemstone
artists, the production cutter, and the repair shop. You notice I
did not include gemstone dealers. The reason is that most gemstone
dealers do not cut their stones themselves, they are not gemstone
cutters. Gemstone dealers cut in Brazil, Korea, Thailand, SriLanka,
India, etc. They do not cut the majority of stones they sell with
their own two hands. They are marketers. Professional gemcutters do
not make jewelry, that is what jewelers do. If you are a gemcutter
making jewelry you have stepped across professional categories of
business. You are in a new area and I do not know how the rest of
the professional community will accept what you are doing. Many
gemcutters are now choosing this route. Money is driving the choice
as gemcutters realize that the most profit from their products is
realized at the retail sale. Complete jewelry is easier to sell
than parts, which is what a loose gemstone is.
