Sydney weather is at its worst in the Summer months, and this is when Sydney gets the most rain, as well as hail and storms. Sydney can get some extremely violent weather.

A Dome Shelter is a highly satisfactory method of temporary protection from the weather, and it has the advantage it can either be attached to sea containers or just pipe supports - and it can be moved or sold when necessity dictates.

....promptly gave the Rat the position of Under-Secretary to the Minister, which the Rat thought was a fabulous position and title - but he soon found out the job just actually meant getting copies of reams of documents to Bull , so he could sign them.

The problem then was, Bull wasn't sure what he was signing on a number of occasions, and as the Rat had got one grade higher in school than Bull before being expelled (a point which regularly annoyed Bull, as he thought he shouldn't have been put down a grade in that year when the Rat jumped ahead in school promotions), so it was often up to Ratty to explain to Bull what those big words in the document meant, such as............

Face it - you don't even think about taking to the air if you're on a limited low income, or a pension - unless it's a corporate pension, of course - which then lends a whole new world of meaning to the term "struggling on a pension".

Marty - Yes that Jap motorbike axle nut is M22 x 1.5. It appears it fits a wide range of Jap bikes. I didn't even think of motorbike axle locknuts yesterday.

Danny, this looks like the same connector and you can get it from a Victorian company.

Marty, I'm sorry, but the news is all bad from my neck of the woods. I went to several fastener suppliers this afternoon and lucked out everywhere.

1. I went to A&M Bolts down the road from my workshop, and he didn't even bother looking! He just said, "Go back to your manufacturer and buy the nut as a part".!

I said, "That could be a bit difficult, the bloke is building an aircraft from a kit!" He just laughed and walked away!! So much for that first attempt!

2. Next up was a rural supplies warehouse - AgParts Warehouse. No joy, they went and looked, and they have never stocked any locknuts like it.

3. I went to United Fasteners, thinking "this is where I should have gone first!". But the request drew furrowed brows and a quick search and a definite, "No"! I thought this strange, as United list them on their website. Maybe they only stock them on the East Coast. The blokes were helpful, and made a suggestion to visit Jaycar, as some aerials use those size nuts.

4. I went to West Coast fasteners (big supplier) and lucked out again, even though they searched and checked their stock records. They've never kept them, nor sold them.

5. I went to Rudd Industrial, who supply virtually everything to do with rural, mining, industrial and construction. Got a helpful girl who looked up the computer and said, "they're $6.60 each" (!) - and she went out to the warehouse to find some.

She came back, and said there were none in stock, and didn't even say if they could get them in. So that was a dud effort, too.

6. In desperation, I dropped into Jaycar and got another very helpful lass, who said they didn't sell individual nuts on their own - but she did have one customer who came in an bought complete switch assemblies, simply for the similar type nuts - and then he binned the switches, because he only needed the nuts, and couldn't get them anywhere else!

I looked at the switches she talked about, and unfortunately, both the switch and the retaining nut (which I think probably was M22 x 1.5), were all plastic! So much for that idea!

So, I'm sorry, these nuts are obviously rocking horse manure. It may help that because there's more manufacturing industry on the East Coast, you will have a better chance of finding the nuts there.

Our suppliers seem to hold mostly mining and construction and rural supplies, here in the West. Good luck with your hunt.

Ian, you haven't put up any reason/s for the change, is it to save $$'s, or to make administration of the sites easier for you? I'm not concerned either way, but there could be a lot more overlap and confusion in discussions if the sites are merged.

Quite a fascinating video, and one of the few I've watched right through to the end. But yes, the younger woman is typical of the younger generation, playing up to the camera.

I never saw any curve templates being used to check the profile anywhere when sanding, which is what I would have expected.

Danny, not being pedantic, but it's called a sensor, not a sender. Parts people will be pedantic about this. The sensor (P/N 456180) measures oil pressure only, and I would have to say the plug is a Rotax special, and it only comes with the Rotax harness assembly, P/N WH-00096.

Yes, I'm sick of the postage rorts, they seem to be just an extra money maker for Australian businesses. If you complain, they come back with excuses as to the cost of labour, packaging, etc - but all these are normal business costs, anyway!

USPS has lost vast sums of money over the years (mostly by paying people based on education level, rather than the job they were actually doing - so a mail sorter with a PhD, got a PhD salary!) - and now they're intent on getting it back by exorbitant charges.

eBay rort you on postage, because they won't allow American sellers to ship without using their shipping arrangements, which substantially increases shipping costs.

The Chinese ship cheaply because the Chinese Govt has a big investment in airlines and shipping lines, and the shipping of Chinese items is subsidised, which is their way of supporting Chinese industry and manufacturing.

Marty, let me see if I can find something locally and pop it in an envelope to you. A large letter can be sent Australia-wide for $2.40 and it can be up to 20mm thick and still qualify as a large letter, provided the weight is under 125g. Even if it goes over 125g, as long as its A4 size and less than 20mm thick, it's still only $3.60 for 250g, and $6 for 500g.

The old engines had tight clearances when factory new, or freshly overhauled. If you gave them curry from new, the heat buildup from the tight clearances could easily see them seize up - thus the explicit instructions for "running in".

Todays engine technologies means engines can produce full power and be loaded up from new, because new engines are not "tight" to allow for "break-in". Current engine designs and materials means wear levels are very low in engines today.

Marty, try Multispares truck parts. None in Tassie, but they're in Melbourne.

How do you come to "understand BRS's have an excellent safety record in saving lives," - could it be that the BRS manufacturers are telling you this? -  where is the empirical evidence?

Well, Dan Johnson writes up a persuasive argument for BRS's - and the simple basic fact that many (and often innocent lives) have been saved, can't be ignored as "sales-speak", and provides the "empirical evidence" you speak of.

https://bydanjohnson.com/brs-logs-save-number-400-using-airframe-parachutes-definitely-saves-lives/

And even the writers who take an aggressive attitude against the fitment of BRS's, end up agreeing they have saved lives, and will continue to do so.

https://www.aviationconsumer.com/industry-news/is-brs-always-a-life-saver-not-exactly/

One can't help but be awed by the European Alpine scenery - but the restrictions as to finding a satisfactory area for a forced landing, must be a real concern!

Adding safety features has to be a big bonus in any item of equipment - but the safety feature has to be seen to work to become successful. No safety feature is ever going to be perfect.

I can still recall when we laughed and sneered at airbags first being touted in cars (in the late 1970's). We reckoned they'd kill more people than they saved. How things have changed!

I recently sold an elderly neighbours car for him (a '96 Mazda Protege) and one buyer refused to purchase it, because it had no airbags! This, despite the car being a low-km car in superb condition.

I still don't get the attitude towards the refusal to wear seatbelts in cars. It must be a "the Govt isn't going to tell me what to do!" mentality behind it.

The local Police recently announced a safety drive to educate rural motorists in particular to wear seatbelts, as it has been found that in more than 20% of rural crashes, it was discovered the victims weren't wearing a seatbelt.

I lost a particularly good young employee, aged only 20, when he either forgot or refused to wear his seatbelt - despite my business' safety directives outlining seatbelts were to be worn when driving the company vehicles. 

I understand BRS's have an excellent safety record in saving lives, and I fail to see the continued opposition to them. I understand the weight penalty and the high cost is a deterrent to owners of ultralights, but I believe RA-Aus would be well advised to simply recommend the fitting of BRS's, but stop short of mandating them, due to the complexities involved in the fitting to the wide range of aircraft currently being flown.

Good seatbelt systems are simply a very effective way of saving lives, even in light aircraft crashes.

Lots  of turbo's will damage your ears

Turbos don't produce the same noise level as Roots-type superchargers, because the rotation of the curved lobes in a Roots-type blower, with their exceptionally-close rotor clearances, is what produces the ear-splitting scream.

In fact, that clearance level is so tight, that if a Roots-type blower is operated outside its designed parameters, it can seize up, with obviously disastrous results.

A Roots blower doesn't actually compress air to any substantial level, it simply pumps it without any real pressure increase. So despite the fact that GM 2 stroke diesels were supercharged, they were still defined as naturally-aspirated engines.

The Roots blower on an engine simply acts to pull in increased volumes of air to fill the vacuum in the intake manifold.

However - a turbocharger, thanks to its turbine design, actually pressurises an engine intake. You can get turbochargers to produce over 40psi of positive intake pressure.

Naturally, this makes for substantially increased power if the engine is built to take it. However, both superchargers and turbochargers have a problem with the heat produced from the compression of the intake air, so heat exchangers or "charge air coolers" are often used to remove that unwanted heat, and to increase the air density going into the engine.

Heat exchangers or charge air coolers are most commonly used in conjunction with turbochargers, because of their levels of heat produced from the compressed intake air.

That's the bear-est level of remote region assistance in Canada that I'd expect.
