Hi MikeR
This is the combination I use for over a year now, and am quite happy with it.
NOW.
But: At the beginning I didn't get any drinkable result out of the two of them.
I have the Solis with the little button in front where one can grind directly into the head - think it's number 177.
There is another -older- type, without this button - think its number is 166.
In a forum I found out, that 177 (with button) cannot grind so fine than the older model.
Also in a shop in Vienna they told me NOT to take the newer 177 as it grinds too rough for a Pavoni, but it was too late, I had it already.
So I wrote to Solis in Switzerland about the problem, and they told me they knew about the it, and a little repair would solve it.
They sent me a document with detailed instructions of how to disassemble the grinder and reassemble (the big white wheel inside)
to another notch - or send the grinder to the factory (at my cost).
It took me an hour or two until I fully understood the process and reassembled the thing correctly, but since then my Solis grinds a lot finer, allthough still not fine enough to my feeling.
So I have to press pretty hard to get enough pressure on the lever for a crema. (I guess more than 15kg)
Usually I press in two steps, first fill the basket loosley directly from the mill, then press, and go on grinding until there's a little heap on the basket. If I then press again, I'm exactly the 2mm under the rim of the basket, as my Pavoni likes it.
What's funny is, that the first pull on the lever (after waiting for the first drops to come out by themselves) needs a lot less muscles to push it down, than the next one(s). I somtimes need a lot of power to get the lever down.
Wonder how the Solis - Achille combination will do.
In general I like the Solis very much!
As I have several partly quite old machines with very different needs on grinding, its very comfortable, easy to change setting,
and it looks so good
