Dave, Thanks for the pump photo, did you notice any front panel flex inserting the group handle ?

The Duetto 2 had visible flex and the D 3 was improved by adding a support behind the front panel.

Thanks for the picture Dave.

I am curious about the flex in the front panel too.

You have mentioned using an 8mm gasket to prevent flexing.

There is  one I have found that says it is softer than other gaskets.   It looks more flat than rounded and I wonder if it is what you mean?

Wouldn't changing to that type of gasket take care of any flexing?

Thanks again!

This is what Dave said.. i dont see any comment about flexing

"Another is around the group gasket which although a  nominal 8mm is actually 8.3 - 8.4 mm thick and has to be locked in quite hard to be secure. It's the same on most of  the machines from Italian manufacturers and the main reason why most of them have strengthened the front panels on their machines. I have specified a very specific brand of gasket from an Italian supplier that is exactly 8.0mm thick. It's also a little softer and the portafilter locks in at the correct position and can be locked in with the lightest press of your little finger (should you so desire) and still not leak, or untwist under pressure. The gasekt won't last quite as long, but that's a good thing, because in an ideal world people should be changing them every 6 - 9 months depending on "on time" as they all start to harden after that.."

Do you know the name of the brand of gasket Dave specifies?  The one I was mentioning in my previous post is made by Wega.

I was thinking, if I got the new Quick Mill 2B instead of the Mini Vivaldi, that I would go ahead and get one or two of the gaskets and change out the one that comes on the machine.  That would take care of the flexing, if any, and also make it easier for me to lock the portafilter into place without straining my wrists.  I have a bit of arthritis anyway and if I can make it easier, that would be great.

I really dont.. He is in the UK. Maybe call CCS and ask. Or maybe Dave can tell you the name..

How difficult is it to change LED lights?  

I was looking at them on Amazon and they have bags of 50 white LEDs for $5.00.

I just don't understand how they are replaced.

I was thinking that the blue LEDs could be replaced with white ones which wouldn't look so bad.

The LEDs on Amazon have two rigid wires coming out of them and I don't know if these have to be soldered or just plug into something.

Anyone know?

Also, what material would the cover for the LED lights be made of?  Some type of plastic or would they be glass?  I can't make it out on the Chris' Coffee
Facebook page.  I would assume that replacement covers would be available if they should accidentally get broken?

I am sure the LED's will last quite a while, and CCS will probably carry replacements. Main concern for me will be that the machine performs well and has good fit and finish.

I really don't care about the LEDs.  I just meant that if they actually are blue, as it looks like in the pictures, I think white would look much better.

I wonder if the LEDs are really blue?  My husband said that it might be that the store lights give them a purple/blue cast in the pictures but that may just be an effect
in the picture and not be giving the color rendition correctly.  I know that florescent lights give weird color effects in photography.

I was wondering what the cover over the LEDs is made of mainly for how it would look with the machine. I would most likely not turn on the LEDs anyway.

I am sorry it sounded like I was concerned about the LEDs burning out and worrying about how to replace them.  I was thinking about the change of color.  I should have
been more clear in my meaning.

I wish we would be given the choice of lights or no lights.  I really don't want them at all, but they really aren't a big deal since they can be turned off.  The main thing is that
nifty motor/pump setup which finally gets it right with the pump below the motor so it won't leak into and ruin the motor.  That I like!

I think we should be happy that CCS is even bringing this machine in for us. There was no plan for this machine to be part of the CCS lineup! I wouldnt give up until someone brought this machine to the US!  Forget the LED lights. Its a non issue.

Just for a bit of information about gaskets. I fit exact 8mm gaskets on all my machines and it means the portafilters lock in really nice. If it's all fitting right, you can lock a portafilter/blind filter in with the lightest press of a little finger, hardly exerting any pressure....and it won't leak. Of course i use a tiny tiny bit of pressure, but certainly no real force at all. If the gasket is just slightly too thick, your on the steep rising part of the lugs and the portafilter has to be locked in much harder to be secure from untwisting under pressure. The QM  front panel has been reinforced at the rear, similar to the Duetto III or the Rocket. Although QM don't just use an extra plate, they have turned up the edges for better rigidity (just a tiny engineering detail some other manufacturers have missed), I was so impressed I took a photo of it for my own personal records and wasn't going to mention it in the review. The photo is below, with the arrow pointing to the extra folding to make the plate more rigid.

The manufacturers genuinely believe we want portafilter gaskets that last years, which they gauge by how far the handle eventually moves round as the thing compresses/hardens...by then your having to tug  it really hard for it to seal! I sometimes leave mine in longer than I should 9 months or longer...but usually I change them every 4-6 months. This is because they become harder after that and the feeling of a nice new gasket is so much better. Also I drop the shower screen every 3 days to clean group and behind screen as well as screen itself...so this often makes the gasket looser over time and again 4-6 months (and my machine is on every day all day) is a good replacement period. They are very cheap when bought in bulk. I buy packs of 20 and that's probably 7 years supply. I think if people changed them more often, it would increase demand and encourage the retailers to sell packs of 10.

The gaskets I like and use, because they seem to fit really well in Duettos, and QM machines among others are:

http://www.nuovaricambi.it    Part number 516528/N

This are an exact 8.0 mm, while others seem to be nominal and slightly larger....they also seem slightly softer. Must be different grades of Viton? They don't last as long, but so much better in use. You might find the machines come with them as standard though, because I have specified they are used for the UK spec machines. Chris will probably have got a standard QM group gasket, because they won't have bought supplies of these gaskets yet.

P.S. If your machine is on a lot less than mine, then 6-9 months might be a good group gasket replacement period.
