Thanks for the replies guys. I'd not realised that chestnut/sweet chestnut were different. Doesn't sound like it's worth the bother on that basis. I'd seen chestnut for sale and assumed it was horse chestnut. You learn something new everyday! Cheers Craig

I was talking to a friend last night, and he told me that his brother has had a covenant on a large horse chestnut tree removed and is going to have it chopped down. He wanted to know if I wanted some firewood!! It's a big tree and my initial reaction was "wow that'll be worth quite a lot" he...

Hello, I'm doing a similar thing with a number 4, 5 and a record 180 block plane. I'm interested to know what method you used to de-rust bits and strip the handles. Cheers Craig

Thanks all. I think that physical polishing is the way to go initially. I don't want it perfect, but I do what some of the things to look nice. It's not simply a case of then being usable! The coke was interesting. It made it worse from a colour perspective, but it did seem easier to sand...

Nick at cadsoftsolutions provides very good training and I'm 99% sure he covers sketchup. I've spoken to him about other things as they are local to me in Cambridge and he's a jolly nice chap. I'm also pretty sure he regularly does training remotely, so if there a few people who are interested...

Err, but you didn't. Instead you provided a statement without caveat or context. Anyhoo ... OK, I'm happy to accept your personal experience and retract the "regardless of the source of the flickering" part of my post. However I maintain that shadow flicker from a wind turbine is highly...

This should not be ruled out, but a lot of research has been done in this area, and it is currently considered highly unlikely. Epilepsy in action did a survey in 2007 and one person did say that they had a seizure whilst looking at a wind turbine, however that person didn't suffer from...

Hello, I built one of the electrolytic de-rusting tanks a few days back, and whilst the results are impressive, I'm left with dull grey metal. I have tried water, lightly sanding it, steel wool, metal polish, t-cut metal polish, alu oven cleaner and silver cleaner - all without much luck...

... and soda stream!

An interesting (brief) overview on power storage http://www.windpowerengineering.com/des ... age-media/ I'm reluctant to bring up electric cars again ... however ... There is also a lot of interest in the expected increase in electric cars. This effectively means that there will be millions of...

Assuming (for arguments sake) that the turbines were expected to have a load factor of 25% it changes the point of the article entirely. It stops being "wind farms are useless" (I'm paraphrasing!) to "wind farms perform exactly as expected". If you wanted to spin this differently it then becomes...

Clearly wind power is no good without some storage medium. When wind starts to contribute a bigger percentage of the power used then this will be more critical. Currently our grid operates in a way that can be turned on/off as needed. They simply turn on/up the power stations during the day an...

I'm not dismissing it, I'm simply saying that a report stating that wind farms aren't very good written by a group that is against wind farms needs to be considered within context, and any potential bias borne in mind. Unfortunately a lot of people won't do that, they will accept biased reports...

So what's the answer then Digit? It's easy to pick fault with everything and simply say "this won't work", "that won't work", but it doesn't add much value in solving the problem. What's your view? What should we do to safeguard our children's/grandchildren's future in say 100 years time? How...

I wonder what % efficiency a modern car typically operates at? I genuinely don't know, but would be surprised if it topped 50-60%. The efficiency argument is the one that is usually used to attempt to rubbish wind farms, but I wonder how well the figures compare against other similarly large...

An independent study then :roll:

Who mentioned low? I didn't. I said not constant. But since you ask ... Common sense suggests that any method of generating electricity that doesn't involve constantly burning a carbon based fuel will eventually be more efficient (from a carbon footprint perspective) than one that does. Both...

Er no it isn't. Not all energy sources are carbon based, hence there isn't always the same carbon footprint. There will always be a carbon footprint, it will never be zero, but it isn't constant. The problem that I think you're alluding to is that the majority of electricity is made by burning...

House was built in 1974. I've had two reputable companies look at it and they both agree that it's AIB and not cement sheeting. They were both fairly adamant that this required a licensed contractor to remove. They are talking about building a 4 stage decontamination chamber with shower in the...

I will if nobody has one, but no sense in buying one if somebody else is about to throw one in the bin.
