Pembrokeshire Our first holiday in Pembrokeshire ever . That must be good, but in August with the school Holidays? We aimed to do the three main peninsulas and then drive through the Cambrian mountains to our regular folk festival at Shrewsbury for the bank holiday weekend. 1) Broadhaven We aimed for Trefalen farm campsite on the beach. It was full but a farmer's field campsite was not much father away an gave us a relaxing informal stopping place. We did the beach, walked round the Lily ponds from the old Stackpole Estate, walked to Barafundle bay, and along the coast to the west. It's an amazing coast . A playground for sea kayakers exploring the coves, and climbers taking on the challenges of the vertical cliffs. Weather was great so we stayed four nights.  lilly ponds Hidden bay to the West Barafundle bay 2) West Hook farm near Marloes and close to Skomer Island. lots of places with English and Scandinavian names rather than Welsh. ...

Our Domestic CR80 fridge had a cheap noisy computer fan. And the fan comes on every time the compressor Switched on, regardless of the air temperature. 1) Cut a 120mm hole behind the fridge and fitted a vent cover. 2) Bought a simple thermostat with the intention of running the fan only when the compressor was on and when the air was too hot. Once I had the fridge out, It was not at all clear whereto put it, or even how the radiator worked . 3) Replaced the fan with high quality salvaged fan. Not good. It rattled, sounded like a noisy computer and then packed up. 4) Bought a new quiet fan,  PQ277 Gelid Silent 12 cm , Fitted it behind the fridge, because there was not quite enough space between the fins. -... That seemed to work well. Not quite silent but hardly louder than the compressor itself. 5) then the fridge light failed . I tracked it down to a failed voltage regulator. Salvaged fan and original small fan. Original fan top right. Mains/12/24V corner ten (now ...

We are always nervous about gas leaks and gas smells, so I wanted to get it all correct and hare it tested. That involved.... Replacing the rubber hose to the oven., because all internal pipes should be copper . That meant taking to oven out and patting in a long s-shaped length of copper to the manifold. All the joints that I look apart looked messy from repeated tests with washing up liquid. They say it has salt in and is corrosive. So I bought so specialist leak detector fluid that is supposed to be non-corrosive. It is yellow and sticky though. Used more PTFE tape on the joint to the Paloma water healer, but it was not convincing . No leaks showing with the fluid though. "Gary'' came to help. He soldered an 8mm to 10mm reducer to make the joint simpler.    pressure lest paint. It passed the manometer test. I must make a manometer. The gas pressure is only 37mbar that is 1/30 th of an atmosphere. So it just needs a U-tube with one foot of water and a ruler. Pre...
