I will drop the temps for my medium-dark roast - but I am not sure what ratio you mean

I am less than 1:2 at the moment (21g in/40g out) - or do you mean a different ratio?

LMSC

ManicAsif You are doing almost 1:2. It’s fine. I was only saying a longer shot may not get the desired outcome. In your case, 21 / 53g would be 1:2.5.

LMSC

ManicAsif shot 3 - in 21g /out 40.0g - PI = 5.9s; brew = 36.4s, dunp at 6.8b (without puck screen, but ground slighly courser)

This looks good. The other two shots are too long. I would recommend losing the puck screen and see how it goes. With 21g, 50+s shot and puck screen you would be over extracting. If you really like to keep the puck screen for that dosage and grind size, loosely tamp and see.

A much much better coffee day today. Pulled 4 shots today - each and every one has been delicious!

…and importantly very consistent!

pretty much the following:

in 21g /out 41.0g - PI = 6.0 s; brew = 32.5s, dump at 6.8b (without puck screen) - also changed group/brew temps to 90/97

So, guess it will be all change when I get my a) IMS 14/18g basket and the b) 14g basket

..but right now a very happy bunny!

Thank you for all your help guys

Send all new new gadgets back . Stat happy. 😎☕

What pi pressure have you settled on. I think more stable slightly above 2 bars. That rotary pump is a bit too efficient, but i like what I have set now.

ManicAsif

Adrianmsmith

i haven’t played with the PI setting yet, still using the factory setting of 2 bar

once I am comfortable with the basic operation of the machine, I will have a play around.

And after: 😍

Also received the flush lever with very clear installation instructions :). Super fast service!

Adrianmsmith

Ive also asked for a price for the black tray. 😎

Not sure about that book though 🙃😜🫣

Blackbirdman

Replacing the flush lever should be done when the machine is cool, ask me how I know ;).

I quite enjoy reading that book. Not that it told me a lot of new things, but still.

The finish on this drip tray is better I think. It sits a bit too snug but I think I can fix that.

Adrianmsmith

Blackbirdman

That machine really is cool 😎

But hope it didn’t hurt too much 🥰

I got my flush lever in the post the other day, haven’t got around to fitting it yet.

letting the machine cool down is noted :)

which method did you use? I glanced at the instructions, and seem there are two methods suggested

Blackbirdman

ManicAsif I used the 1st method. It is really easy but do look for the right nut to be removed. Mine was on the left side and since the pin can only be removed via that side there is no need to remove both. (I removed the right one only to come to the conclusion that was not the correct side ;) )

@ManicAsif

just a bit of hopefully useful info for you, :-) you don’t need it to fit the lever but in case you think there’s any risk…..

There’s no risk at all removing the back domed nuts and or the studs to get access,

The 4 domed nuts can all be removed. the whole lever / piston unit will just sit there. only saying this in case you were thinking its under spring pressure. if required the whole unit can be lifted out (in a few months when you feel the urge to look and add some moly 111 to the seals!!)

i added copper washers purely for cosmetic effect. in the early days i think the guys were using PTFE washers for the same. I considered titanium, then saw current prices!!

ManicAsif

Blackbirdman @Adrianmsmith

Thanks guys, just replaced - very straightforward :)

That said, I am quite dissappointed with the new lever. There is alot of sideways movement (i.e wobbly) though it functions fine - it looks quite industrial when compared with the stock one. (which was/is nicely machined)

I don’t understand why ACS couldn’t just engineer a rod that fits in the already existing hole of the stock lever - Ok, you lose some of the adjustment offered by the new one - but, this wobblyness is going to do my head in :)

I might just look to find some kind of 3mm diameter steel rod and refit the stock one

…unless of course, I have done something wrong and others aren’t getting the sideways movement

Blackbirdman

Adrianmsmith currently I don’t have washers in place. Is there any need for them? I also didn’t reapply glue to the studs which were removed. I was wondering if that is necessary?

Could you further explain the molykote remark? I have read about it a while ago but can’t fully remember….

Adrianmsmith

Blackbirdman

you do not have washers!! as i said :

Adrianmsmith i added copper washers purely for cosmetic effect.

you may think it looks shit!!!

Blackbirdman also didn’t reapply glue to the studs which were removed. I was wondering if that is necessary?

my opinion "as its not under pressure it is not necessary. purely belt and braces.

Blackbirdman Could you further explain the molykote remark? I have read about it a while ago but can’t fully remember….

sorry for mentioning moly!!

not absolutely necessary as the seals are excellent but some prefer to add a little lube periodically. period subjective as well.

you can either remove the shower screen and pull the lever (machine turned off) and add a smear of grease to the cylinder wall and the top piston just under the lever or

remove the whole unit just because you are interested what is inside (!) and grease the seals and inspect them directly.

—

in all cases ensure you are using the Food Safe silicone grease such as Molykote 111. this is the thick stuff, not the runny stuff to use technical terms!!

Blackbirdman

Adrianmsmith I will probably open it up one day since I am definitely interested how it looks inside. So thanks for the advice anyway!

just to wet your appetite 🙃

ManicAsif Did you have a flush lever before?

Do you have a photo close up of the spindle area?

Is the wobble from the spindle in the group holes, or the holes in the lever.

Adrianmsmith

ManicAsif

Could you post photos and video otherwise we have no clue what you have or could have done. 😎😜
