Scaffold Sheeting

Having got the remainder of the main frame done but obviously having insufficient time to do any roofing the thought occurred to me that the wood might get a bit damp at times during the winter.


Post Post

It's well past time to catch up on the last bit of 2016's building progress. Let's start with a blog post about a timber post.

My last blog post finished with the finally-sourced appropriate replacement for the split post having its bottom end appropriately slotted and drilled. The actual post replacement operation turned out to be a bit complicated, too.



As I mentioned in my previous house post, things had been going slowly and haven't sped up since.


Mike Phillips PV Water Heater

Previously I wrote about the problems with connecting PV panels directly to an immersion heater in which I suggested using multiple immersion elements switched by relays to achieve an approximate match to the PV output as the sunlight varies.

A year ago I had some email correspondence with Mike Phillips ( about designing such a system for use in Spain. Pleasingly, he's just reported that he's only gone and done it and has had a system working for a while.


Grid Intensity

There's a little group of people centred around the OpenEnergyMonitor project/products doing some very good work related to reducing carbon emissions over a wide range of scales from monitoring and control equipment that people can use in their own homes to supporting studies for CAT's Zero Carbon Britain project.

However, they do seem to me to have too much interest in the realtime carbon intensity of the UK grid (measured in kilograms of CO₂ emitted for each kilowatt hour of electricity generated). While looking at these figures can be educational, I think it's too easy for people to be mislead in a way which would actually increase emissions in the short term.


Frame Up

It's been slow going but now most of the post-and-beam frame is up.


Last Post

There's been some nice weather and some not-so-nice weather. The bad weather hasn't been terrible - just finely judged to slow things down with the minimum amount of effort with days of drizzly showers and winds just high enough to make lifting purlins be not really sensible.


Transit of Mercury

I ended my previous blog post with “Looks like wind and/or rain (mostly “and”) till Friday now. We'll see.” We saw; it was. Though it dried up as the week went on it was windy until Friday, but things have been a bit better for the last few days - particularly today (Monday) for the transit of Mercury.


First Purlin Up

I've now got the first purlin up which is pleasing as it was something which was worrying me a bit. I had various schemes but wasn't sure what would actually be practical.


4th, 5th and 6th Frames

The last week or so has been quite wet and windy (usually both) and I only managed to get the three tie beams for the next frames done, each on a separate day. Yesterday (Tuesday), though, was much better and I got the joist holes drilled in the posts for the last three frames and the frames put up.
