Hello Robert and other readers,

Look at the topic, "Fiorenzato T80 micro-switch problem "
Skip to page 2.

Wow, that is a good looking manual you made there.
Great job !

Need some time to read it, get back to you on it.

ps. The figs and pears in the pastry are fresh from our garden!

Hello world,

Only having some difficulty in setting the correct grinding-grade.
Feeling the shaft with my finger when it turns, I feel a slight "wow and flutter".
So its not completely centered.
Any ideas what to do about it, can it causes the grinding-variations ?
Let me now.

For now I call it the day,
Made a nice picture of the MD50.
goedendag,
Bernard

"wow and flutter" nice choice of words. that's old school man!

Moving right along.

Hello Robert,

That's a profi paintjob you have there going on in the backyard.
Skipped the chroming for the moment I suppose.

Yes the W and F, is from the cassette-tape period, DISCO.
When getting more detailed it is sometime harder to find the correct words.

At the moment I am back to pre-grind coffee.
When adjusting the grind-level, it turns from to coarse to to fine.
Going in reverse, up the scale again, it remains to fine, even on the numbers where it
was to coarse in the beginning !?

Rara, dutch for question-mark.

If you have a tip......

Yes, I skipped the chroming process because the machined areas are difficult to protect from the process. It may be impossible and I got tired of researching it and not getting a clear answer.

When I was in the Navy I used install 1 inch tape recording systems on submarines and calibrate them. We measured Wow and Flutter, Total Harmonic Distortion (THD), Gain Vs Frequency etc. It was a cool job.

back to the topic...

I think you got something wrong when you reassembled. Mine is still disassemble so I can play with the parts and see if I can recreate your problem. I wont be able to look at it until tomorrow night.

With some bench testing I found that the motor start relay would intermittently stay engaged keeping power to the start windings. I could shake the relay between runs and sometimes it would work correctly. <image>

As it turns out, these relays use gravity instead of a spring to return to the de-energized position. In my original bench test I had the relay in what I thought was the upright position but in actuality the relay is mounted underneath the steel plate in the bottom of the grinder. I have retested with the start relay positioned correctly and motor runs nice and cool indicating that the start windings are disengaging and the relay is working correctly.

The education continues!

Hello Robert and readers,

After a nice holiday in BELLA ITALIA with great weather and
bonnisimo cappochino's, back in Holland.

Enjoying the art of homebarista, even extended the machinery with a caffetiera
from Bialetti, model Kitti with a brass handle.



Used this model during our camping-trip, really handy, and best achievable quality
when no juce/power is available.

Hope to see the sequel of the above project,
ciao from Holland
