An assembly in the DownsSteam workshop which allows air regulators which are used in locos and carriages to be set to their required pressures. The type of regulator shown is used in the loco 106 and in the carriages. March 2024. PiP 1 shows the oily gunk which has to cleaned from the insides of a regulator after years of service. We use paint thinners with brush and rags to wipe down and wash out the body and the removable parts, and compressed air to blow out the thinners and gunk mixture. PiP 2 A closer general view. PiP 3 The gauges showing 660 Kilopascals input pressure and 40.7 pounds per square inch regulated output pressure.

Our shower head needed replacing. My wife selected this one and installed it. Sadly though our low water pressure due to our location on a ridge the water dribbled rather than sprayed out. Experiments with blocking holes with insulation tape suggested that blocking a quarter of the holes would correct the problem. I found the cap of our insect spray pressure pack was the size needed to block enough of the inner holes. Metal snips and a file soon had the flat top ready and silicone was used to glue it on. It has been in place for a while now and is working well.

Smell the marmalade my wife is cooking! It's cut up, sugar added at the whim of the cook (recipes are for the timid), brought to pressure and held for a few minutes them left to cook as it cools.
