Unstable partners. More friction than a P-Zero.

Welcome. I have been to Alexandria. Drove from Weymouth, via Thame, pressed a reset button, then went home via Newcastle and Thame. Was a long day's drive.

When machining plastics, woodworking machines are often used, these cause micro fusion at the cut edges, which makes them look as though they are solid. So hard to tell from a machined part.

Not measured them, but they look to be the same extrusion sizes.

It is being taken up with them. We are not a small company. But I am more interested in the physics, not the legality. I wanted to take the new ones away, seems to me an accident waiting to happen See lower down. I think 3 bolts, stop some of the 'rocking' and as they are nearer the centre line, there is more material in tension. A greater cross sectional area for the forces. Below is a picture of one that is failing in my opinion. The bean is already bowing and you can see how little distance there is between the bolts and the top edge of the beam.

Good. I have some projects for your students to do.

No. Aeration is a common problem when extruding 'fractional melt' plastics. I think the main problems are that the top cord was too small and with only two bolts per arm, 'rocking' soon becomes excessive. Triangulation is simple, cheap and sturdy.

A large, multi national always has plenty of insurance, this is not a two bit company like yours.

Have you seen the film Sexy Beast. Pop Don Logan (Sir Ben Kingsley) into it, and retile.

This is, on the face of it, quite comical, but is actually serious. We bought 3 new, recycled plastic, bench and seat combos. These are not cheap ~£700 each. We got them from the same company as the last ones that have been excellent. So, a 'large' family visited, ordered food, went outside, found a bench and 3 of the women sat on one side. The seat supports snapped, sending them to the floor. Luckily no injuries, and we were quickly tending to them. We removed the broken bench, offered to put two table benches together so all 6 of them could sit, but they said it was OK (2 of the men and one woman, the very heaviest ones stood and ate). Come the next morning, I have a look at the damage, all the new seats seem to be failing, the old ones are fine. The difference seems to be that the old seats had 3 bolts on each support, and they were in a smaller triangle in the arm. The new ones had two bolts, but closer to the edges, leaving a thin strip to take the majority of the tension. Hopefully the pictures below will make it clearer. So one for @Gus Potter, @saveasteading and anyone else interested in materials and how they can fail in usage. The broken arm/seat support, with no 'meat' at the top. The detached seat. Close up of the failure, which shows a lot of aeration in the extrusion. An old bench with the 3 bolts in a small triangle. This has lasted a few summers.

According to the local rag, many have gone back to residential properties, rather than holiday let business. From chatting to other people it seems that many if the smaller, cheaper, hotels are below capacity. We are having a good summer, which is strange as the weather has been been good, visitor attractions generally do better on rainy days. Yesterday was a record day, third this summer. Only 3 more weeks of summer left, roll on September.

Tourists pay my wages, I want more. Tourist numbers in Cornwall are down 40% this year, that is partly down to the decline in holiday homes.

Stick with it. Very few people get an opportunity to self build. And it always takes longer than people think. You will get lots of support, if all kinds, on here, just ask. I am sure that a few people that are local to you will drag you out for lunch/coffee/a laugh. That helps.

I got caught speeding on the A11. 5 points and a £270 fine. That was a 23 years ago. They are only used to tractors.

It has a motorway, my nearest is over 100 miles.

I could do with some walk on glazing, about this long and that wide.

Basically yes. More air will enter via the MVHR and less air will exit via it. Overall the MVHR will allow the same amount of air though it, just in an unbalanced manner while the kitchen extractor is on. You could not put any MVHR pipework into the kitchen and have a basic through the wall heat recovery unit, and the hob extractor, or if you fancy a bit of DIY, fit some electrical isolator valves in the ductwork to isolate the kitchen when the hob is on. Or just don't over think it and sleep peacefully.

Welcome. If @Pocster recommended you then we can only assume you are a female hostage victim and your release fee was to build something over many decades.

It is meant to. Remind me, is the PIR going on the outside or inside (warmside)? Always best to foam/adhere the boards to reduce air movement. A VLC has to cover everything ideally. Think of it as a bag that stops air and moisture getting to outside, the MVHR does that job.

Could be worse, Antony Worrall Thompson and Ainsley Harriot. May all your doughnuts look like Fanny's. Keith Floyd and Graham Kerr for me, and Graham is still alive, missing half his fingers mind. You have unusual vegetables.

As you are from Suffolk, probably potatoes. With some Saffron for colour.

Airtight and vapour tight are not always the same thing. There is also the problem that buildings move over time, and any finish onto masonry will fail in time, so fit the internal VCL, it is only a polythene sheet fitted and taped carefully after all.

As you have MVHR fitted (or will have), I really don't know hink that 25mm of insulation on the outside will make a difference. Just fit it between the battens,hard against the wall, it will act like a rain screen. OK the condensation point may move a bit, but probably only a few millimetres, and only in very rare weather circumstances. You want a VCL on the inside, masonry is not immune to moisture (if it was then 'damp walls' would not happen in old houses).

The force of gravity, and therefore time, changes depending on altitude and ground density. All the granite in Cornwall makes it 20 years behind the times.
