many ways we have designed the LIDO hand coffee grinder to address or
correct many of the shortfalls of current mass produced coffee grinders
but rather than compare the LIDO to existing hand mills we would like to
examine the LIDO for what it IS rather than what it is NOT. To begin,
as with any grinder, one considers the grinding burr.
use a fairly standard 38mm conical steel burr set in the LIDO. The
type of burr used in any grinder determines the characteristics of both
the grind and the grinder.
The inner burr is mounted on the end of a stainless steel axle using a bolt that threads into the axle through the burr.
The outer burr is mounted in a solid aluminum carrier by use of high strength threadloc compound.
proper alignment and consistent grinding we add a system of two oil
less bronze bearings fit to high tolerance to the axle....one at the top
and another right above the burr fit in laser cut aluminum plates.
These two bearings form the central alignment system of the grinder.
Now you can picture this system like wheels on a car...the axle freely
spins in the bearings held at each end in the aluminum plates.
For convenience in adding beans we add a tall rim on the top plate.
bean hopper is formed by use of a polycarbonate tube between the top
plate and the lower bearing. This hopper will hold about 10 tablespoons
of beans. Due to the length of the polycarbonate hopper there is no
need for a cover on top...very few pop outs or beans jumping out.
The components are all joined using long rods covered with nylon tubes.
outer burr carrier is added below the bearing (and one aluminum spacer
to allow for top clearance of the inner burr). Slightly enlarged through
holes in the carrier enable accurate burr alignment.
Below the burr carrier is added a solid aluminum spacer to hold the burr adjustment mechanism.
catch jar lid is added along with the burr adjustment mechanism.
Burr adjustment is made by using the threaded cap nut and locked in
place by the wing nut acting as a jam against the adjuster bar. This
system allows stepless adjustment of the burr. The pointer (t-cap) on
the adjuster bolt head helps the user keep track of the burr setting.
assembly bolts are tightened and the outer burr carrier is factory
aligned . The ZERO point of the burr setting is indicated by a brass
washer visible under one of the assembly nuts.
catch jar is a standard 70-400 continuous thread neck size 8 ounce glass jar. The glass jar helps reduce static.
crank handle is solid aluminum and has two threaded holes allowing use
in two different manners.....using the longest handle length one tends
to grind in a two handed bicycle motion and when using the shorter
handle length the grinding motion is more hold with one hand and turn
with the other...you choose!
Here the LIDO is fully assembled and ready to use....HAPPY GRINDING!!!
