Looks really good, love the coffee bar layout...so neat as well

The o ring needs to be there...It may well have perished and simply gone through the pump. Without it the balanced bypass won't work correctly. You then might well get high pressures from the pump as it won't move against the spring correctly.. If you write to Fluid-O-tech, they "might" give you the...

I assure you it's not a cultural thing in Naples, in fact I'd be surprised if it's that way anywhere in Italy now, things are tough. The delays on this were getting things right and getting parts, and high quality steel etc

They certainly do and if the success of this machine allows them to hire more people, then it will be a win win. So far they have made huge investments in equipment so they can do more in house and improve the machines, whilst keeping costs down. Computerised Bender, Laser Welder, Automated laser cu...

If it's an Evo and especially with a safety system....probably, because the Vostok already had the shot timer and plenty of space for the Rotary, the Evo had quite a big redesign in terms of case and internals (which the Vostok didn't need), so took a bit longer to bring to market. The Evo2 is desig...

The safety release would have been the reason for the delay. I got one of the 1st ones back in Jan/Feb I think it was, and was not happy with all aspects of it...I know they have worked on the issues and resolved them relatively recently. I did advise them strongly, not to send any machines out with...

If people who ordered after you are getting their machines now, it's worth dropping Maria at ACS a line and asking if there is some reason, or an option you have chosen, causing the delay? If not, you should ask her to expedite your machine

Id depends on the boiler material. I don't know what it is it could be low lead brass <0.25%, T.E.A. coated low lead brass, AISI 316L, I don't think anyone uses nickel plated brass internally any more preferring TEA. So it probably not from the boiler but from the ring group, so it should stop event...

That is a true horror of an expansion valve. You could put a more standard one in, but you would have to change the plumbing a little. A longer but of silicone tube. Plus routing the high pressure tube to the threaded and of the expansion valve. Using this or a similar expansion valve. {link}

I discuss this here "ACS waiting times" as similar comments already came up. Hopefully it will help answer your questions. I don't think LH covered it as well as he could have done, probably down to time/video length
