Help with Cunill Space grinder

[timohawk]

Hey all,

New member and loving Coffee Snobs! I picked up a Cunill Space grinder off Gumtree yesterday and I am stuggling to the grinds to a reasonably fine level.

To gets grounds finer, you rotate the plate bringing the burrs closer together. There is a button that presses agaist the rotating mechanism that provides resistance so that the top burr stays still.

No matter how much I rotate, I am still getting a ridiculously course grind (half beans). I seem to have ratated it as far as it will go but the result is pretty much the same regardless of how much i turn it.

I called the seller and he said that it was working fine last time he used it and all he did was clean it out. I feel like a part may be missing..

Can anyone help here?

Also, I think this guy may be a bit big for my becnh top, provided I get this thing working, how much do yall think its worth?

Perhaps this is a silly question: Is the problem that the grinder is a SPICE grinder?

Unwind the adjuster to a point where you can remove the locking pin. Inspect the underside of the adjuster, the pin, and the inside of the hole that the pin goes down into, and work out the correct method of assembly because as far as I can tell from the photos, the pin is assembled incorrectly , resulting in what you already know.

TOK is right on to it. I have a Cunill grinder myself and the photos you have included show the locking pin preventing the top burr from descending far enough. You should easily be able to unscrew the top burr plate to free the locking pin underneath. You will then need to sit the pin in place with the top burr wound far enough out (almost entirely to the top) and then wind it back down into place holding the locking pin in position (it should all make sense when you get the pin out). There should also be a spring that keeps the locking pin engaged with the top burr plate until it is depressed by hand. Make sure this is still in place.

You may also want to take this opportunity to inspect the burrs. if you keep winding the top burr plate it will eventually unscrew and you will be able to see the face of both burrs.

Let us know how you get on!

SUCCESS, thanks guys !!!!!!

Checkout the second and third photo.... when I got it from the guy the locking pin was under the adjustment plate, just had to move that above and everything makes sense.

Now onto microadjusting to the right grind size, is 10pm too late for a coffee... we'll find out.

Thanks again !
