  1. Looks very kitchen friendly but I'm not a fan of the curved corners. I guess the main thing that matters is what it produces
  2. I was expecting to see some abused machine but it looks well looked after. Whats betting it gets near to a grand ?
  3. If you want to create some revised seals to resolve the problem for the few, having a product that all are happy with, let me know. I will test on my machine and report back. Thinking about this, based on the same routine, same grind setting - one seal working as expected, the other not. Theres a chamber that fills with water and then is pushed out of the chamber via the puck, under the pressure of the spring. The only way that the grab point can be higher is if less water is entering the chamber or some of the water is escaping back over the seals. The water will not be compressing any further. @dfk - a bit of a test that we could do. Ive just pulled a shot using 16g coffee - grind set to 32g @ 30 seconds and let it drain all the way until the puck is dry. Weights were 44.9g coffee in the cup + 16g water in the puck. I know that our coffee will vary but the amount of water dispensed should be similar. This would be an interesting comparison and give a dirty indicator on volume dispensed. I'd run both tests on my machine but it would mean destroying the Londinium seals to get them off.
  4. The video is the same as I experienced with the silicone seals
  5. Thanks Paul I'm not after a refund. If you have some over sized seals I am more than happy to try them and report back. The longevity of silicone seals is the thing that appeals to me.
  6. These were bought as part of the forum group purchase so were bought directly from yourself but not by me. Your seals are not the same as OEM - the material is significantly different, Dimensions may be the same but the seals are not the same. The seals I am using are the old style Londinium seals. I'm willing to try any suggestions that you may have to make the seals work. Offering suggestions on this thread may help people other than myself. I still have the silicone seals in a drawer.
  7. As Ive said repeatedly I would prefer to use the silicone seal but it doesn't work for me. I posted a video some time back showing the high grab point. Its not something that I am imagining or making up. My point with shell was that they changed the product to work with all car models rather than blame Vauxhall. I'm sure you can see the parallel that I am drawing. Londinium seals give me a low grab point, silicone seals give a high grab point - theres only one variable changed. More than happy to try a revised seal if you decide to make some. Edit : Ive just re-read your reply. First you ask if a humble seal can make a difference, then you agree that the material can make a difference. Then you go on to dismiss 'lever slip nonsense' and tell us how many thousands of seals you have supplied. I run my own business and if I dismissed my customers issues as you do, I wouldn't have many customers. Just my twopenneth Paul. Rather than defend a product which (in some cases) isn't fit for purpose, consider making a product that works as effectively as the OEM product, regardless of the group. If you are unable to provide that product then consider withdrawing the product or adding a disclaimer about the potential issues. This is the second thread where you have defended your product to me. Not once have you offered me a solution.
  8. Although I have no experience of any of them you have three options that spring to mind if buying new. Silvia, Gaggia or Sage. If you are willing to look at second hand then you will get the occasional bargain that comes up on here - mainly HX machines. If it was my money I'd look at buying used
  9. A lot of the advice is still relevant but there are advances since then. There is more up to date information but searching for it isn't always easy. What do you have in mind, any machines that take your fancy currently ? And how much are you looking to spend ? The machine types are as they were 6 years ago, albeit some new players on the block and a few machines with added technology.
  10. My seals were bought in late 2017. Think I ought to get a new set ordered as this will have been in the machine for almost 2 years now
  11. Hi David Cafelat didn't work for me. The grab point was much higher than with the harder rubber. Grab wasn't as positive and you never got that take up of the grab where you know it is going to be a great shot. Changed back to Londinium seals and all was instantly good again. As Ive said in previous threads, I wish that they did work because they are much easier to install and should last much longer than the hard rubber ones. I would be the first in line for a redesigned silicone seal that overcomes the issues that Paul sees in the group design. Edit : Ive only used Londinium seals and the silicone seals. Not sure what the standard seal is (maybe the Londinium seal ?)
  12. Absolutely it can. The two materials are very different. One is like an elastic band whereas the other is much more rigid. It is the only connection between the piston and the cylinder walls. One works, the other doesn't (all of the time). Blaming the design is lazy. The group came first - the challenge, if you are is to design non OEM part, is it make something that works consistently. Remember Shell creating a petrol that killed Vauxhall engines - rather than blaming Vauxhalls engine design they pulled the product.
  13. Stating my interest in this too, should you decide to make a second batch
  14. I tried cafelat and left them in for a good 6 months. Bite point was too high and wasn't positive. I tried wrapping PTFE around the groove that the seal fits in but had no better results. Changed to Londinium and bite point was much lower and much more positive. There was a thread where this was discussed and the tolerance of the group was blamed for the poor performance. Seemed to be a case of a poor workman blaming his tools to me as I'd increased the diameter of the seal 'bed' with the ptfe. All I gained from it was that they work for some but not for others which is a shame because the idea of a silicone seal with longer life appeals to me.
  15. Why not take home a bag of beans from the shop and compare to the coffee in the shop ?
