1 group lever from ACS - Vostok 1 group

I have a Vesuvius and an early Londinium 1 and the Vesuvius case is incredibly solid. Probably just the connection to the drip tray is where it might need strengthening as stress on this area isn't a thing on an E61. An exciting project. I'm telling myself that it will be too heavy to carry to use at Farmers Markets in order to save my back - and my wallet!
 
Its definitely in the region of 35kg. I lift it to and from a car 8 times each weekend!

I wish it was 25kg 💪
 
Looking forward to seeing these in the wild. Love the look of the LSM group but all my accessories are based around 58mm so the thought of doubling up was a step too far. I know there was a counter balance weight added to stop tipping but not sure what the final nett weight is. I've got a Vesuvius, similar case, and that's no lightweight as it is. My L1 has a peak pressure in the region of 7 bar and would be interesting to seeing the pressure the two springs reach
 
Anyone know what the final weight ended up being with the counterbalance added. I've seen a figure of 35kg+ mentioned
 
Have seen it mentioned that the cup height from the drip tray is very slightly less than the L1. Does anyone know the actual height, say from tray to bottom of the lever group. When I measure the Vesuvius it was 150mm, The L1 136mm
 
There appears to be more flex than I expected. I have a Vesuvius and an L1 and the Vesuvius case is a monster in comparison. Yet there is virtually zero flex on the L1, as can be seen in the countless naked shots. I'm guessing it doesn't affect the shot, just one of the effects that happen. Doesn't remotely look as though it has any chance of tipping so probably nothing to be concerned about.
 
It's in both videos, more noticeable in your one though. The rest of the shot is perfectly still but the group (and handle) clearly move down on both the initial pull and when the lever is release. As I, and @Denis S said, I don't think it matters tbh but it is there
 
On a side note: I see the flex and I know it's a double spring group head but it will only get worse with time and use. I hope Mr.Cortese will support the front panel with more weight (or any solution possible) even if I have to pay extra. I'm on the 2nd batch with 2 machines, one is for a friend who I convinced of selling his Synchronika in favor of the Evo Leva.
I wouldn't assume that any changes will be made for the 2nd batch. Those involved and also those that have received their machines had indicated that it's not an issue so unless Paolo confirms it I guess your one will be the same.

I dont get this facination its almost cult like. If you have one brand then the other is terrible...
I don't get this either - almost childlike behaviour. I have an original L1 and an ACS Vesuvius and the customer service has been excellent on both with Paolo and Reiss going above and beyond.
 
The depth of bed on these baskets is significantly higher than a 58mm for the same dose. Which, all things being equal, will mean grinding coarser for the same shot time. So on the 98mm HU you are not grinding as fine as on 58mm. How this affects fines / pour characteristics will be interesting to see. I think the basket shape is a major reason why these levers produced great shots and maybe shots at 11 bar will suit different burr sets than std baskets
 
Like buses. Hardly any mention of the Vostok1 through all 57 pages then 2 new users come on preferring the aesthetics to the Evo Leva.
 
@Like Medium Strong Coffee I think the reason that people attack it from the bottom is that the white spacer ring is compressed to centre the piston. So if it's removed from the top makes it tricky to slide back in as you need to relieve tension of the piston first, hence the need for this tool. If you have a tool, there is no need to touch the 4 bolts at the top of the group. This was from the same HB thread mentioned earlier.
 
curious why @Jony is opening up his - perhaps to remove one of the springs on one of the groups?
Someone should tell him the on switch isn't inside the group😂

That's the problem when you leave it unused for months - you forget the basics
 
Less of that. If you like to know the spring came fitted wrong way round from the factory and wasn't checked 😁
Bugger! Was that on one group or both?
 
Bit confused here. I thought the preference for low pressure was the HU SSP burrs. Patrick has the LU SSP burrs. Does it apply to all SSP burrs as that's news to me
