The GemSmith miniCutter
portable... powerful.... professional !



Designed by a Gem Cutter for Gem Cutters !


Design and Development

   As a gem cutter for over 11 years, an opal cutter for 8 
(as a member of the American Opal Society), 
I found myself cutting gems--not bookends or belt buckles--that were
seldom bigger than my thumbnail.  I began to wonder why I needed 
 something nearly 3 feet long to create a half-inch gem!

And sometimes-- sunny days, for example-- 
I didn't want to cut on the workbench, but on the patio, 
even on the dining table one evening. 
I wanted something I could even take on the road, to club workshops,
in my little trailer…to the gem shows.
Same reason you grab your laptop computer,
instead of the desktop model... 

I wanted something portable, professional, and powerful! 
   So, a gem cutter designed a gemcutter—a miniCutter!

Why only 4 wheels?  As I began to cut opal, turquoise, sunstone, and other gems,
 I found that I seldom started on the 100g wheel, but more often the 220g or even 280g,
 especially with opal.  A "softer" start meant you didn't accidentally cut
through the fire layer in that black crystal opal!


I found I often needed a trim saw more than I needed coarse grinding wheels! 
 So, I chose the saw over the coarse wheels, and to my surprise, when I tried
a 220g NOVA on it, I could also shape agate
 and other gems with a Mohs hardness of 7 or so!
 Takes a little longer, yes...but the trade-off for portability is worth it to me-- 
to have all the basic functions of gem-cutting in one portable miniCutter!
Saw, grind, sand and polish--even buff--if I had to take 
one gem maker to a desert island, this would be it!  

 So, opal cutters might use the miniCutter with a wheel sequence of 
280g, 600, 1200, and 3,000,
 while agate cabbers might go with 
220g, 600, 1200 and 3,000 
 and then to the polish laps. 
 I get a nice glossy finish on most agate I've cut--
Holley Blue, Laguna, red flame, Coyamito, chrysoprase, etc.--
with 1200g followed by a 3,000g lap polish!   

So, I trade some extra shaping time for portablity!


And what portability!  Under 24 a 14" footprint!
The miniCutter is about as wide as your laptop computer--
with a 5" trim saw built-in!  
 And handles for those of us who'll never be Olympic weightlifters!  
 Now I cut in the kitchen, on the patio, at the club workshops--
I throw my machine in the trunk
 and run it off my Honda generator at the gem shows between sales! 

 The miniCutter features small things I like in a cabbing machine: 
 an AC outlet for two additional items—pump and a lamp, say.
Storage for an alternate polish lap.
An optional “rip plate” for slabs too large to fit on the table.
Handles for easy transport. An optional tote carrier
for even easier transport to and from the car! 
A blade guard easily removed, or positioned in the cut, 
 to accommodate longer cuts. Twist-nuts to speed blade changing.
And more!



  But the best feature of the miniCutter is “Constant Cutting.”

Whether I'm cutting an opal or an Oregon sunstone, I hate to break away
 and go to a trim saw, or change a belt or a wheel set, and interrupt my focus...
a real "gumption killer!"
I want ALL my blades and wheels running constantly--constant cutting--
so I merely move the stone  back a wheel, for a spot I missed, or forward to polish,
without some exercise in mechanical aptitude!!  The miniCutter has ALL functions
 operating ALL the time--trim, grind, sand and polish at will, no waiting!   

Constant functionality to keep you cutting a gem
not hunting for a wrench! 
 Opal cutters, especially, will find the miniCutter a delight, 
 as they move back and forth over the wheel sequence.

[Side note; When I researched, I was astonished to find that not only is
there no other portable cutter that features this "constant cutting" action, but there
aren't even any bench models that do!  The miniCutter gets you from rough to
finished gemstone without breaking that "zone" that you get into when you're chasing 
a fire layer through some Lightning Ridge crystal opal!]  


   The design philosophy is a salute to the retro simplicity of lapidary cabbers
of the 60s, the Highland Park-, Frantom- and Star Diamond machines 
 that were built simple and sturdy, and seemed to last forever. Metal,
 where it makes sense, and plastic--as little as possible--where it makes sense! 
 But more important is that simple design also means simple SERVICING of these machines...
they are designed so most any handyman can make simple repairs or replacements
with common tools, and common skills. 

The simple design, combined with modern diamond wheels, and XL drive 
 components,make the miniCutter powerful, flexible, precise, durable, 
 and simple to service.  Belts, pulleys, arbors are all standard American parts,
 manufactured here in the USA, and servicible locally, as well as through factory service.


Some techies and old-timers will tell you that a machine 
 with a single  speed (approx 1500 rpm)
 can’t provide the correct speed for sawing, grinding, and polishing.
Ideally, a cabbing machine should have a  fast saw speed, medium wheel speed ,
 and  slow polishing at the lap. Theoretically, they are correct.  

But when this little quibble comes up, I simply pull out the amazing opal cabs,
 Carnelian, sunstone, and Royston turquoise I’ve made on the miniCutter.
If the proof of the pudding is a beautiful glossy polished gemstone,
well, I’ve got them! After they’ve seen the gems, I don’t hear much of
this concern again!    

The diamond wheels provided are Diamond Pacific NOVA wheels--identical to
their Pixie wheels--which I've never seen surpassed for quality and longevity.  

The arbor shaft will accommodate any 4” wheel with a 1” bore (center).
The goal?  Allow the gemcutter every opportunity to outfit, service and upgrade
his machine himself, and not lose 3-4 weeks of time and expense shipping and
re-shipping a unit, or a part.  Web-based service .pdfs and videos will also be available...
free to owners!

I hardly use my large bench cabber's like going back to a grand piano,
when my portable keyboard makes beautiful music too!  

 The miniCutter has been in the prototype stage for about 8 months, demo'ing  at the American Opal Society, Quartzsite Powwow, the Victorville Tailgater,  the Vista Tailgate show, and the Torrance show to enthusiastic crowds.


When two miniCutters were demonstrated at the Jan 2011 American Opal
  Society meeting, the comment in the next monthly newsletter was:

Members practice[d] cutting and polishing on [the] machines....
                  most were impressed by the compact size of the unit,
 and its versatility!"  

  The comments I get at the shows are generally "Cool!" and often
"I could put that in the RV!!" ,
quite unsolicited from me!  I had several folks ready to put in orders at the Powwow, before I was even ready to "price"the unit out retail!
