Uneven Bottomless Portafilter Extraction

Post by Velcro » Sun Jul 22, 2018 10:50 pm

I need a bit of help and advise - please move if in the wrong group.

I've been working with my naked portafilter.
I tried to get even distribution by smoothing, shaking, tapping and WDT and my results are all the same.
I get an occasional spritzer but my basket does not fill in evenly.
It starts on the outside ring, and moves in but does not cover the basket evenly (many gaps see picture).
The picture is at 10 seconds (5 sec pre-infusion + 5 sec pump) and it doesn't fill in until 22 sec, the shot finished at 32 sec.

This happens with both the double & triple baskets.
The picture is with the IMS triple dosed 19.5g
Switching to a Reg Barber 53.3 C-Flat solved most of my spritzer issues but the shot still does not fill in evenly and is over and under extracted.
What am I doing wrong? I seem to have the best results with hard horizontal tapping to level and then a vertical tap to settle prior to tamping and a light (no added weight) polish but my best needs a lot of improvement.

thanks for the help

Is this common?
How do you distribute?
