Saw a setup where the pin is pressed in and than a tapered grub screw is screwed into the pin to increase the "interference". Long time ago and cant remember if it was a crank or something different, same priciple though. I see there is after market rods available for the 503 in the states. I believe rotax don't condone it for aircraft 2 strokes but.

This is the satirical headline story from the Bell Tower Times - Perths equivalent of The Onion. The bloke may not be familiar to East Coasters - but he's John Hughes, W.A.'s longest-lived car dealer, and a legend in W.A. He turned 90 last December, and still runs personalised TV ads and asks car buyers to call him personally, and regularly states, he's "W.A.'s most trusted car dealer". He's also Alan Bonds BIL. Yes, THAT Alan Bond. But John Hughes has managed to evade any of the Alan Bond taint, in his business dealings.

Farley seems like a reasonable sort of individual with a realistic outlook, that is less hardline than Paulines approach. I'm surprised he's thrown his hat in with ON. Perhaps he'll be the sure hand on the tiller of ON and bring some stability to the Party. Or perhaps he won't last long, and there'll be a falling out, and he'll be booted from ON.

The problem looks to be more so with the twin cam example as given in the video, ie a hollow pressed crank pin with a welsh plug in the centre. I wouldn't think tack welding the pin would get much penetration and strength in the long term. Some people replace the welsh plug with a solid pressed pin in the centre of the crank pin, extending full width of the flywheel.

Popular giant Bunnings has swallowed two large firms whole in a mega merger – including the owner of Hard Yakka and Australia’s biggest industrial and safety supplies firm. https://www.realcommercial.com.au/news/bunnings-swallows-industrial-empire-whole-in-mega-merger/?campaignType=external&campaignChannel=syndication&campaignName=ncacont&campaignContent=&campaignSource=newscomau&campaignPlacement=socref

It’s not just the $50b although to be fair we don’t know whether those contracts would have been let anyway or who might have got them had no donations been involved, but it’s also about litigation that has been quietly dropped and regulations that have been amended to their advantage.

I'd never heard of David Farley before he ran for One Nation in the Farrer byelection. I read in a news article that he's an ex managing director and CEO of AACo. It was a fair while ago, he served in that role from 2009 to 2013. For those that dont't know the company, Australian Agricultural Company is Australia's biggest cattle and beef producer. been around since 1824.

It's not a circus! It's a carnival. I can't wait to see what happens when the show is over.

Modern day investment strategy - better returns than the stock market? As reported by "The New Republic": " It was always pretty naive to think the ultrarich individuals donating to Donald Trump’s $400 million ballroom project were doing so out of the goodness of their hearts. A new report from the nonprofit government watchdog Public Citizen has calculated that 14 ballroom donors have raked in more than $50 billion combined in government contracts over the last six months. For reference, that’s more than the GDP of countries such as Iceland and Senegal." https://newrepublic.com/post/211423/donald-trump-ballroom-donors-government-contracts

Spoken like DeNiro.

Press fits also Induces high stress in Parts before any extra load even comes into the Picture, from an engineering point of view.. Nev

They used to employ Nuts each side with Tapers, but it's better to Have More metal to press into The spline thing has been used for years now with No problems. Later Harley bottom ends are used for a lot of performance Specials. High interference Press fits cause distortion in what you are pressing into and you end up with unsolvable run out issues. Nev

You talkin' to me?

I thought of splined pin design as soon as he started talking about the twisting problem. I wonder what welding does to the heat treatment of the steel. The pin has to be hardened to exceptional hardness to meet roller bearing hardness levels. Arc welding puts a lot of concentrated heat into the items being welded and creates localised stresses. Another anti-twisting technique would be to install a rectangular plate bolted into the end of the pin, which plate would lock into the flywheel plates via a recess, or via blocks on the flywheels - provided there was clearance for the blocks.

Don't worry - tomorrow will bring an entirely new and fantastic world-beating project, and the tunnel will be forgotten. And then when someone brings it up again, he'll deny proposing it - because it's fake news. In fact, it's tomorrow already, and the latest dream is Trump-class battleships. And the USN is ready to order billions of dollars worth of high-tech steel for them, and no-one has even started on the plans for them yet. https://www.abc.net.au/news/2026-06-06/trumps-battleship-plan-poses-new-risk-to-aukus-committee-fears/105765176

Not even funny, Nev. Factual, and sadly, believable.

That would be Obvious to anyone with Nuclear sub Knowledge and I doubt it won't be OK.. That would be a Basic. Nev

Hang on You are not allowed to criticise Rotax's. That Bloke's just trying to sell his product in super dumbspeak. Years ago Harley went to Splined Pins that Broach the spline in the wheels, when pressed in and it cannot move by twisting but it's a Once only thing, done at the factory with special alignmment presses. The whole shaft and rods assy must Be replaced but at Much the same cost as a normal rebuild. The usual term for that type of rod is Fork and Blade. A couple of small weld runs won't last Long as a repair. The Flywheels are steel forgings with the Mainshafts integral..The assembly HAS to be built up as the Big end Bearings are caged Rollers. Nev

"someone" Mentioned to Trump that "we" might have to Borrow and funnel the money but he thought they said Burrow and tunnel.. Nev

Is that so Chump can escape to Russia when the American public actually get a clue?

Correct.

Nuclear subs have an hour limit on the reactor. When that limit is reached, the sub is decommissioned. If we get old Block 3 Virginians that the yanks have been thrashing for 10 years or more, half their useful life may already be gone. Can't run these buggers "on condition".

More importantly, will it be gold plated and named after trump?

I read somewhere unreliable (x), that there is a plan afoot to dig a tunnel between Alaska and Russia. Is this for real? It would cost Billions (whether Rubles or USD). How would this Make Amerika Grate Again?

This can be a problem with Rotax 912's or any pressed crankpins.
