I have found it easier to dial-in with these burrs over the stock Ceado burrs. The distance between the absolute zero and where I dial in for espresso is greater with this grinder. This has effectively expanded my dial-in range on this grinder making movements of the adjustment collar less touchy and easier to predict their effects. See photo and explanation below.
The Ceado adjustment scale is odd to me but here is how I notate it: Between the numbers 0 and 1, there are 5 hashes. I notate like this0
.2, .4, .6, .8, .10 1
So, as per the photo, my old absolute zero point was 7.4. The new absolute zero point is 6.6. (I did a quick alignment job with foil shims on both burr sets) I guess the effectiveness of alignment on this style of grinder is up for debate but I did it and it is better then when i didn't.
Further, my espresso range is quite similar. It may have moved -.2 or .3.
So with the old burrs, my dial in for RBE was 0
.4 (six marks) ahead of absolute zero. The dial in for the same coffee with the SSP burrs is 0
.2 (10 marks) ahead of absolute zero.
This has made dialing in easier because when I make a move of the collar with the SSP burrs installed, it has less effect on the time of the pull than when I made the same move with the Ceado burrs. In effect, the espresso range on my grinder is larger. This makes dialing-in less touchy and easier to predict for me.
This is all sorta preliminary stuff, i have only had them for like a week and i have only dialed in 2 blends: Redbird Espresso and Nossa Ernesto's. But i have tripple checked the new aboslute zero and i am finding adjustments more predictable.
I hope all this made sense!
