Experience with Genii lapidary grinder
OBSERVATIONS - I purchased my 6" Genii machine used. It is single
speed and came pre modified to use 2 wheels on a side.
This was done by using a larger spacer and an additional inner hub
spacer. The right hand side spins on and off by hand. I am looking at
one of my SPARE WHEELS
Just make sure you get the rotation correct. There are arrows on the
wheels. I would not move the wheels to the other side without
checking. I believe that diamond Pacific has replacement inner hub
spacers which would allow you to make up more special or dedicated
abrasive or polishing wheels. The outside end of the inner hub spacer
is drilled and tapped for a flat disc. believe this will accommodate
a number of discs sizes.
The air pump is on the left side. A notation reads " remove painted
screw to oil pump and leathers " There is a needle valve beside it to
adjust the air flow. There is a water tray to hold cooling water. If
it were rinsed out or smaller, individual water trays were used, the
use of fresh and uncontaminated cooling water should take care of any
MY OPINIONS, LIKES AND DISLIKES.
Likes - This machine is sturdy, simple, durable, repairable,
portable and modifiable. I believe Diamond Pacific still sells
replacement parts for it. The motor can be rewound, the bearings
replaced, Virtually everything can be shop made. There is a built in
light and magnifier. I can pick it up and move it. (I have it, a 6"
saw and small gemstone drill press all on a shop parts table which I
have modified to be the correct height. It is forgiving (a prime
Dislikes - This machines motor runs hot. Diamond pacific told me
this was normal. This is not a high production machine. If you want
one then buy one… The Diamond Pacific Titan is such a machine I have
used them. TIJT had 6 in their lapidary lab. I have a highland Park
E - 50. It is from another age and could be steam driven if desired.
But never to be under estimated.
I WOULD MOST EMPHATICALLY RECOMMEND THAT ANY LAPIDARY MACHINE BE ON A
GROUND FAULT CIRCUIT FOR YOUR PROTECTION. Portable ground fault units
are available very reasonably. - Just do it.
I hope this helps. If needed, email me for consolation and
