Back in the 1980's, had a girlfriend that moved to Cambridge, the place was so (expletive deleted)ing backwards that on a Sunday you needed a car as nothing was ever open.

One I still use.

Does beg the question where the fire engine will turn around.

Not really. a 230V to 110V transformer electrically isolates from the neutral. There are two separate windings. If you ground either of the secondary (110V side) windings, the voltage drops to zero. At zero voltage, no current can flow, so it is intrinsically safe. The other reason is that in the past, it was cheaper to buy in 110V equipment from the USA and add an isolating transformer, than build 230V and 110V units at home. You are talking two different things here. One is getting the wall wet, the other is dislodging dirt. Wetting is just mass transfer, the other is breaking a mechanical lock, which may require a minimum power or energy level.

These places are rentals. So may well be rented out to the 'hard to home' people. In a developing country we call these ghettos.

Yes, as that allows more electrons to 'flow' at the same speed. Electrons, which have a mass, are the particles that do the work. But we should really talk in coulombs (an amp per second). There are 6.241509×1018 elementary charges in a coulomb.

Shall use the old pipework analogy. You have to get some water from one place to another, in a set time. You can use a large diameter pipe with a slow flow, or a small diameter pipe with a high flow. The diameter is analogous to the amps, the flow to the volts. (the trouble with that example is that it does not take the resistance of the pipework into account, which is assumed to be laminar at all flow rates)

I posted a response, asking you to video it. Don't know what happened to it, seemed to have 'vanished'.

No good for polypropylene, polypropylene and polytetrafluoroethylene, so that is most of the recycled plastics out then.

@pir8ped Did you say on the other thread that because the place was small, you did not need the French equivalent to building regs?

Plenty of time then, as long as you live the French lifestyle. Half my family is French descendants, most live well into their 90s.

Well I did my apprenticeship at a materials testing machine company. How much of a hurry are you? Hopefully @Gus Potter will come along with his SE specs on and impart pearls of wisdom.

Been to the woods, seems the new owners of the cafe have changed the benches. But no matter, here is a picture of some ply stuck to a slab that has been out in all weather for over a year. I wiggled it and it did not come off. I am sure a tube of Lumberjack will sort you out.

I glued a bit of ply to a recycled plastic bench over a year ago. If I can be bothered, I shall pop to the woods tonight and have a look. Generally there are better things to look at in the woods at dusk, but for you, I shall resist my urges and just stick to the plan.

Are you saying you have saved £900 over two years on £2500 per year (£5000)? Or saved £900 in your bill, which may be higher than the price cap average. I have not spend £900 on electricity in 2 years, so can't really save that much.

While I think some calculations, or at least some testing, is called for, a full report from a structural engineer is probably OTT. I did that DIY I-Beam test a while back, which was more about testing cheap adhesive. It performed really well. I am sure a few test pieces joined together in different ways will find out what is strong enough. All that is trying to be achieved is the joint expanding when the cord (think that is the right term) of beam is in tension.

I shall have to look at the sketches. But I don't think you will get away with just butting up I-Beams.

Was that 01:00 GMT or BST? Metering times are usually GMT.

Welcome I am going to follow with interest as I think making I-Beams should be simple. Take lots of pictures.

How?

Yes, and very good when it is cold and wet outside, not as frugal as a washing line though.

So do I. Nothing wrong with it at all.

I don't understand them. They whine like hell about the cost of electricity, think they are being ripped off, and when I offered to monitor it for them, they said no. Hottest day of the year down here, think we are technically in a heat wave. They have been at home all day, sitting in Thier garden where their washing line is. They have the tumble dryer on. What (expletive deleted).

You may need to redact some identification on it, though I am not sure how useful an MPan is to scrotes.
