Well I am trying to pull the graph on coffee freshness vs time. Even you don't use it to grind, can use to monitor beans freshness!

And this is coffee thread, press or drip don't give coffee lover the coffee joy?

Don get me wrong about me against press or drip, i just sharing my thought on the devices and not about drip or press.

Why so serious? its all about coffee and it says can go up to espresso grind! so we just debate only!! and heck i still love the ordinary Kopi-o in kopitiam!! but still hates starbucks!! Its a price and quality thing!! if you can relate to it!!

@d33 WOW i saw your ms silvia is sold!! so no espresso for you already? or u've done mod-ing your oscar?

Yup, My silvia now is in better hands of new owner only so i can concentrate on my modding. The silvia is attracting me to make more coffee...just joking

Haha, I 'm not quitting espresso yet, I still have my oscar but not in working condition yet (Due to time constraint that i spend with my family so sorry Oscar, you have to wait for a while) and i know it been delaying weeks after weeks now as what could had been done faster now take almost a month plus my new spare parts that worn off just came in.

I'm ordering the boiler retention valve made out of steel to replace my original plastic one

Original valve built consist of plastic and brass.



and this part always broken after used for sometime. u know plastic will erode after dipping in the water sometime. This will lead to spritz and inconsistent water flow.



New mod valve consist of one piece built full metal and brass



used to fixed here



that still on the shipment but i will fixed everything up first then change that later.....since it can be easily accessible without remove all of the item.

Why u think I so serious? 😓
Well espresso grind for these ppl really about meeting min requirements, using in pressurized basket. We not really thinking that small burr out performing hg-one 😜

while waiting for my retention valve kit..... i did some machining customization on the front plate to fit in the lever on the old hole since im pushing the pipe in....





Yeah, i know it is a sloppy job .... the hole look like sh@t and uneven .... you know how hard is it to cut through this high quality stainless steel plates....

LOL you deserve a cookie!! damn brave of you!! what u use to cut? Dremel tool? or the old skool way?

Nop, drill it with bench drilling machine and starbucks for the guy who borrow his machine to me..... i wish i got dremel tool , it would make my job easier but it is too expensive to buy just for 1 time used ....

I'm suspecting another problem arise.... there will be nothing to hold brass steam body except for this plate that mount to the front panel which will lock between lever and the fork... got to try and see if it work. I'm only afraid it will move once i push up the lever for temporary steam.

For the moment of truth is about to review.... *ba dum tss*



It's alive...... yes, it is alive......

hidden steam wand (Alot of work involve) unlike the protusion ones Less work more easy)....

Congrats. Nicely done
Now to brew loads of espressos!

not yet as the machine is still in the state of 90% complete, I still have one more replacement part comes in which just reach my hand and also i need to solve some minor leak problem

Woah it looks great!! Well done!! maybe teflon tape will solve the leaks?? perhaps make a video once its complete? or better photo angle?

Nop, Wrap a lot of PTFE piping tape.... Still there is leaks, Tried putty for piping also no used, still leaks, only way to check the leak is to remove the leak area, clean and apply thread locker again because i didn't complete remove everything when i did cleaning due to my assumption that the area are not affected.

Hey guys i have a question that has been bothering me for a while now. Why does the coffee to water ration differ between brew methods?

For example, a french press might use 1:10 coffee to water ratio while filter tends to be 1:16 and espresso 1:2. Why is that? Isn't there a sweet spot for extraction, around 20%? And is the caffeine content in all the methods the same, assuming the same amount of ground is used?

Very good question!! you can call it the sweet spot of extraction for each different method is different in terms of variables (Pressure or gravity or manual brewing) also do remember the grind size as well. different method brings out different characteristic of the coffee.

Hope it helps but i don't think i help? anyway just enjoy coffee the way you like it!! i always like to taste what the roaster taste notes are!! and thats my indication of how good a roaster is in duplicating each bag of beans!

Argh, big time screw up, i used alternative substitution loxeal brand of threadlocker (loctite 272), now having hard time to remove them..... this crap is bite strong....

Caffeine content explained here

Yes the sweet spot is 20% thus the ratio

Ahhh Great info pat!! Thanks!!

@d33 Ouch that would be sucky!! Try using a cotton butt soaked with some dissolve solution like turpentine and try to "unlock" it? (I don't know if its safe to use it on copper or your water line, coz its kinda strong and toxic) anyway just a 2 cents. hope you found a solution!!
