Subject: Bodum Antigua Grinder - Tweak Now Requires Security Screwdriver
A couple of posters have recently asked about opening the Bodum Antigua
grinder in order to tweak it for a finer grind. I just bought one
expecting to be able to mod it so I can use it with my espresso machine
-- the finest grind it can do out of the box isn't fine enough for most
espresso machines including mine.

A couple people have posted tweaks over the years that involve opening
the machine and moving internal parts.

<http://www.kwilson.fsnet.co.uk/grinder_tweaks.htm >
and
<http://twoloonscoffee.com/antigua.html >

Trouble is, these fixes depend on an older design where the upper and
lower halves of the machine were held together with friction springs. A
little prying and the thing came apart.

The newer models (including plastic case models, not just the stainless
steel version) no longer open up that way. From what I can see on mine,
the two halves seem to be held together with a screw accessible through
a hole in the base. But the head of the screw is an unusual design,
obviously meant to keep people like me from removing it and messing
around inside.

Instead of a slot or a Philips-style cross or even a Torx slot, this
screw has a triangular slot -- it's simply a triangle, and my research
tells me that it's called a "Triangle Recess (TP3) screwdriver" slot.

Here's what the screw looks like:

<http://www.hudsonfasteners.com/sec/sec_tp3_trs_phsts.htm >

I haven't yet found a screwdriver or bit that can turn the screw. I
spotted one on Amazon.uk, but it's restricted and can't be exported to
the US (where I am). That's because the TP3 screw is considered a
security screw. Great.

That's as far as I've gotten.

Any other suggestions are welcome...

McMaster's UPS charge is competitive, and you might want to order
other things, but ... if this style is becoming more common as Brian
suggests, you might consider ordering one of each size. I remember
buying a T10 driver the first time I needed one, and eventually
needing one of the smaller sizes in my Craftsman Micro-Tech set.

This is all excellent, y'all.

I knew the alt.coffee folks would be on top of this.

Now I just have to measure that little slot to see which exact size I
need, then I'll order the sucker...

So far as I can tell, Jensen has rolled over or been bought out by
Stanley. However, triangle recess bits are available from www.mcmaster.com.
Look for part # 5941A13.

Failing any success with the other replies, I've succesfully unscrewed
these with a standard blade screwdriver of the correct width, but the
screw wasn't tight. Assuming sucess I'd then either replace the bolt,
or adapt it by cutting a groove in the head to accept a wide flat
screwdriver.

Joe (Eager) wants to remove a screw with a:

There's a nice index of screw heads here:
http://www.lara.com/reviews/screwtypes.htm

But there's no entry for System Zero, and they don't sell the tool you
need. On the other hand, the usual emporium sells "triangle power
bits" for US$2.39 (catalog page 2755, items 5941A11, 12, 13, and 14):

The use of this type of fastener seems to becoming quite widespread, I was
trying to fix the tailgate lock on my Jeep, it had this type of screw ! had
to take it to the dealer, cost me 70 bucks for something I could have fixed
in ten minutes !!

Looks like the screw that stops one taking the gears out of a Brio steam
engine when it's been in the sandpit and the gears have got a bit, er, not
very fast. Also like the screw that you need to undo to put a piece of
tissue paper over the loudspeaker on a certain v noisy truck. Necessity was
the mother of adaption.

I overcame the problem by taking an old screwdriver and grinding the tip
into a triangle.

Dunno if it will work on the bodum.

Strangely, I can't see the OP... however, I believe
the "tri-wing" bits from this security bit set are
would probably do the trick.

I'm with Ken though. For a one-time use, I'd just
grind something to fit.
