You are purchasing ONE LONDINIUM piston seal (there are three of these seals on the piston)

This item will ship from New Zealand by post and is therefore likely to take 4 weeks to arrive to most customers

The seals are only 8mm thick so we hope to send them in an envelope

These seals have been developed by LONDINIUM in New Zealand to run with very low friction without grease and provide an extended service life for the seal and also the shower screen, and to eliminate a possible source of channelling (a shower screen partially blocked with silicone grease)

These seals are not made from Viton, nor are they made from silicone, but the material is certified for use in potable water at temperatures and pressures greater than what our machines can impose on the seals

Given you are moving to a no grease seal i recommend that you replace all three piston seals, the group seal, and the shower screen at the same time

You should also take the time to carefully remove all traces of silicone grease from the sleeve and piston

If your machine is five years old or more and the sleeve seals have not been replaced we would suggest you replace them as once they leak mineral deposits from the water will form inside the group and make it more challenging to remove the group sleeve from the group - please refer to our detailed video on how to replace the sleeve seals

Also thoroughly clean inside the bottom of the group where the portafilter locks in

Use water with a drop or two of liquid dish washing detergent to ensure each seal slips over the piston rather than grabs

Dunk the piston in the water & detergent solution to make it slippery too

I use two allen keys, 2.5mm and 3mm, as 'railway tracks' to facilitate to smooth passage of the first and second seals that you fit over the seal grooves of the second and third seals respectively - if you allow the new seals to drop down into a seal groove for another seal it is a real pain; stop this from occurring with the two allen keys and fit the top seal first and the bottom seal last

Rinse the piston under a running tap once you have the 3 new piston seals fitted to wash off any traces of detergent

Finished Pavoni & Fuji PXG4 pid: Probe Inside the Ring

Delicious cup: all the work was well invested! At the end of the previous blog about the pressostat and PID working together , I mentioned that I would like to clean up the xmas tree of wires and have as few cables and probes as possible to visually disturb the classic design of the La Pavoni. Getting rid of the probe that was fastened with copper tape to the top of the brew group was a priority. I wanted to hide a new probe in the cooling fin as close as possible to the brew group. This morning I asked Tije if he could do that. He would need to drill a straight hole of 3mm diameter in the 4mm inner ring of the cooling fin that sits as a tight clamp around the brew group. Always the optimist, Tije set to work: First, Tije made a piece of aluminum to fit the inside of the ring. Drilling a thin hole straight through the curved aluminum, if possible tangentially going through the inside of the ring to touch the brew head directly, you need the support of the temporary insid...

KiwiSDR2 [radio]

  Despite selling one and giving away two of the five monster vintage 'boat anchor' receivers that I had, I still enjoy listening to shartwave radio. The modern iCOM R8600 that I also have has a wider range plus some decoding options but it's not easy to figure out what encoding is used on which frequencies. The SDR-Control app from Marcus Roskosch at https://ham-radio-apps.com/ makes this much easier and also allows some remote control of the receiver so you can place it and an antenna at the top floor of your house while listening downstairs. I also got the SDRplay RSP1B box: This offers a great listening experience at a very low price compared to the iCOM hardware. I had one before and bought one again after a (somewhat limited) Mac version of the software became available. This device needs a computer to be connected to the receiver. For some time now a nifty little device has appeared which not only works standalone, it even allows you or anyone else to utilize the ...

Tiny Cheap Fluid Bed Roaster by Tije and Jan

(also see Daily Coffee News feature ) Tije designed and made the following structure for a tiny and cheap fluid bed roaster, to which Jan van der Weel added the Arduino parts, electronics and programming: Sketch by Tije de Jong Jan sourced a very cheap blower (€ 11) to start with, Tije developed and constructed the mechanics, Jan built together and programmed the TC4 / SSR electronics.  On his blog, Jan will specify exactly how the TC4 part is combined and programmed and I will copy these details into this blog entry, just as Jan will use this video in his blog. We did a few test roasts to make sure it works at all and it does. Towards the end, the first roast tended to get a flat BT line and airflow was slightly decreased. 200g seems max load of green beans. Second roast a little more power was given to the heater. Next we will try the Background Roast driven by the PID software of Artisan. A week later, with updated software that works better to change the...
