For those who recall - I am still trying to get the Olympia Cremina
(model 67 - I think) to work after receiving a basket from Michael. The
sister nor I can do anything worth doing unless I can solve the problem! 
Which is: without the basket the porta filter (gadget that holds the
basket anyway) engages and turns to the right wthout trouble. With the
basket I struggle to get it engaged and it will not turn to the right! I
tried a cup and the water ran strait through as I pulled the lever up!
No resistance pulling down. The basket doesnt seem to be sitting all the
way down, the PF seemed to have a very slight (maybe 1/2 of 1 mm) dent -
cant tell if it affects the basket - also the basket gets stuck when I
remove the PF (doesnt come out with PF)... 
So 
what now?
another basket?
another PF?
replace the entire outside assembly?
Ideas anyone?
Ask me questions, I'll try to answer...
I will take the ideas to Sister Julie this weekend if you have any....
God Bless

Skip,
Good to hear from you again. The basket I sent is brand new, never used, so
may have to be worn in a bit to work smoothly. A new basket can work and be
placed and removed but it helps to be familiar with the normal operation and
know when to push, when to pull, and when to tilt. If it is seated properly
in the portafilter you should be able to place and remove successfully.
If the portafilter is a true Cremina part it is made of heavy brass which is
chrome plated. Brass is a relatively soft metal - if there is an indentation
- can't imagine how that could be on a true Cremina portafilter, they are so
thick - you can sand it smooth with a dremel tool, hand drill or any similar
tool with a very fine sanding disk. Can you post a picture of the
portafilter online (or send picture offline if not) so we can see what might
be wrong and what we can recommend to fix it.
Also, if you look up into the grouphead - the big nosed bell-shaped object
that sticks out the front of the machine you should see the dispersion disk
and a rubber gasket around the dispersion screen that makes contact with
the basket and holds it in place. Can you see the gasket? Does the
rubber look worn? Is the basket getting jammed because there is no rubber to
keep it further down in the grouphead? Pictures!!!
Without familiarity with the machine, most anything you do to "fix" it
will probably mess it up more and possibly lower the value. So if you are
interested in raising money for the Sister's cause then at least consider an
"as is" sale, just being honest about what you have and what you know about
it. But showing us pictures may help us suggest some non invasive ways of
getting it to work. Wish I was in the neighborhood and could just drop in to
take a look...

Skip-
I've seen a double basket from an east coast espresso dealer with a similar
problem. Nothing a file or grinding wheel couldn't fix. 
You will get flow when you lift the lever at a certain point. If there's
nothing in the basket to resist the pressure it will certainly come right
through. 
Without loading the basket and tamping you will not know if the piston
gasket is any good - although with a new piston gasket even unloaded you
should meet some resistance.

Tom,
That basket is from an east coast espresso dealer :-(
