Hi guy's!
I ordered 4 springs from e supplier in Danmark. 2 stainless steel and 2 so-called piano-wire. I installed stainless steel a couple days ago and i already can se some improvements. Pressure is now about 1 bar higher. Piano-wire springs are about 20-25% stronger so i expect about 7.5 bar with these. I installed both regular size and small one. I'm gone test these for 3-4 before i install these stronger ones.
The one in the left is original.

When you install the extra spring, how is it seated? Is there any complication with that?

Hi Gary
Before i ordered these i measured everything so that smaller spring fits perfectly between the shaft and spring. I do not feel any deferences when pulling the lever except its heavier to pull.
I'll been making espresso and lattes for a couple days no and quite satisfied so far.

I am using one after ur suggestions in the past. Might even get to a stainless one proposed. I am going to try the new white strietman seal (it is a 2 oiece). It is a major improvement on the Strietman might make help Elektra.drgary wrote:When you install the extra spring, how is it seated? Is there any complication with that?

I can compare to a Cremina SL as my local friend has one.

Would you mind sharing the specifications of the springs you ordered? I'd love to power-up my SL as I prefer the higher pressure shots I make in the manual group.
Thanks - this is so great to see!

Hi. Spring specifications are as follows:
Outer spring
d:4,00 mm = wire diameter
De:29,00 mm = outer diameter
Di:21,00 mm = inner diameter
L0:130,00 mm = unloaded length
Ln:64,50 mm = max loaded length
R:13,34
Fn:852,20
Inner spring
d:2,50 mm
De:18,50 mm
Di:13,50 mm
L0:130,00 mm
Ln:58,90 mm
R:5,25
Fn:364,81
Material: Piano-wire, is the same material as original spring that comes with machine.
Springs er slightly longer about 5mm. Outer spring have about 13 threads and is 130mm long.

Hi guys
I just wanted to share a small video of an espresso shot with new springs. Im still testing but results so far are very promising.

LuanD: Excellent video, It seems your elegant solution will provide another choice to the Olympia SL concept of 6 Bar espresso.LuanD wrote:Hi guys

There has been other posts for the need of a solution to that-you have seemed to have potentially solved. Congratulations
Looking forward to follow ups.
