Pepe, a fellow alt.coffee-er, asked me to post this mod to the Super Jolly.
It removes the doser on a Super Jolly. Some people hate dosers, others swear by
them even for non espresso usage.
Including it under "Grinder Mods" does seem appropriate - but I am disquieted
by the implication that one ought to spurn the cheaper machines.
"This conversion is a retrofit so requires a bit of adaptation in
the way of expert alignment of 2 newly drilled and tapped holes for the chute assembly and
2 smaller holes for the motor plate cover. I recommend that you read all
instructions before deciding to make the conversion AND BEFORE BEGINNING.
Parts are available from the factory through it's suppliers if the supplier does not stock
them.
Factory parts required:
1. Coffee Outlet Set (chute assembly) - part number S00SGRC01 - suitable for Super Jolly
and Major.
2. Motor Cover - part number SSJ0FRA04 - suitable for Super Jolly only.
These are numbers I got from the Mazzer factory.
SPECIAL TOOLS REQUIRED:
7/32" Black & Decker "Bullet" drill bit
11/64" Black & Decker "Bullet" drill bit
(THESE 2 BITS ARE ESSENTIAL; USE NO OTHER TYPE OF BITS!)
5mm x .80 metric tap
OPTIONAL TOOLS (because supplied motor plate screws are unsightly and ill-chosen):
Center punch with a fine point
Two 4-40 x 5/16" long stainless steel flat head Phillips screws
Standard 4-40 machine tap
Standard 3/32" or #43 drill bit
Small countersink (for a neat cosmetic finish-see below)
However, if you decide to use the supplied motor cover screws, you will need the
following:
Center punch with a fine point
Standard 5/64" or #47 numbered drill bit
Drop of dishsoap and water mix as a lubricant
___________________________________________________________________________________
The spring-loaded leverclamp for the bag should be removed as it gets in the way and is
not used for single doses. Just punch out the hardened pin holding the spring and
lever. I used a proper sized nail with it's tip ground off so as not to mar the
finish.
Unplug the grinder and remove the 2 upper and 2 lower screws holding the doser assembly in
place. The PF positioning yoke is also useless and is attached with 2 nuts and
bolts. To access the nuts remove the base cover by loosening the rear feet slightly
and removing the front base cover bolt. Clean off all coffee residue and place a
cloth inside the grinder to catch any metal filings that may get into the grinder's
interior during the conversion.
To mount the chute assembly hold it TIGHTLY in position to mark the new screw positions.
Taping it well leaving access to the holes will free both hands but make sure it
does not shift while taping. I found it unnecessary to use tape as it is only held
in place to mark the holes. Use a 7/32" Black & Decker "Bullet"
drill bit that fits snug in it's mounting holes just to START AND MARK holes in the Mazzer
with the PILOT TIP of the drill bit. You will be drilling into a curved surface so
slowly drill deep enough to mark the full diameter of the bit. This way you can free
drill with the next bit (tap drill size) without danger of "traveling".
Remove the chute assembly and drill straight back and level with the 11/64"
Black & Decker "Bullet" drill bit all the way though the metal. Cut
the threads with the 5mm x .80 metric tap using dishsoap with water as a lubricant; NOT
cutting fluid.
To mount the motor cover position it correctly and center punch the screw positions. Drill
holes with the chosen standard bit determined by the choice of screws to be used (see
options above). For the "upgraded" screws tap holes and carefully
rechamfer the holes in the motor plate with the countersink so that the phillips heads
finish flush with the plate surface. This is a worthy cosmetic touch so use care as
the plate is aluminum.
You can now mount the motor cover and the chute over it and grind away.
If all this seems confusing it will become clear when you get the parts, take off the
doser and are actually doing it.
To use the grinder is now a really pleasing experience but let me present the method I use
as it is neat and simple. Since I have no bean dispenser I use a 3 oz. Dixie cup as
a weighing container after it's weight is deducted from the scale. After dumping the
dose into the grinder I use the same cup to catch the grounds for if I try catching the
fluffed gounds in the PF they overfill it and spill out. I invert the PF over the
cup (the Dixie cup's rim fits inside the fiter cup's) and upright the two together, tap
the cup to dislodge the all the grounds, remove it, tamp and load without spilling.
A few last details; the spout is free floating in it's mount and rattles during grinding
so I placed a few layers of binder paper hole reinforcements (just the right size) to
cushion the blows. So it still moves to dislodge residual grounds but the rattle is
gone. I also replaced the yuccy lockwashers under the retaining screws with rubber
ones.
The exposure I had during this project to the workmanship of the machine makes me wonder
how $200 or $300 spent on a plastic home grinder is wasted to the enrichment of cookie
cutter manufacturers. For a third more spent on a Mazzer there is 2 to 4 times more
machinery quality to last more than several home grinding lifetimes.
A quote I remember but can no longer trace: "The pain of poor quality lingers
on long after the pleasure of low price wears off."
But I must add that the pleasure and appreciation for this Mazzer provide a daily
fulfilment that I cannot dispell and have totally forgotten about it's cost.
Pepe"
