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.

And it goes on. I think he deliberately just does the opposite of whatever is the right thing to do. https://www.sbs.com.au/news/article/trump-announces-981-million-support-package-for-highly-polluting-energy-source/s7d44jvnp

Well according to the defence chiefs, 3 second hand subs were the original preference as they would be delivered sooner. Why do we need 3 nuclear powered submarines anyway. The navy is spending $1.7 billion on a fleet of our own designed Ghost Sharks. They are designed to do almost everything that manned submarines can do at very low cost as well as low operating cost and we can have heaps of them. They won't say how many but there are apparently dozens being built. Aukus is costing at least $368 billion. https://www.theguardian.com/australia-news/2025/sep/10/ghost-shark-submarine-drone-australian-navy-explainer

For the first time ever an EV is the top selling vehicle in Australia for May and it isn't Chinese but the Tesla Model Y. https://www.drive.com.au/news/australian-new-car-sales-in-may-2026-tesla-model-y-is-first-ev-to-top-vfacts-charts/

It's funny hearing some journalists referring to the government's 94 seat majority. That's their number of seats in the house; their majority is 19 seats.

The major party's bipartisan immigration policy is on the rocks, thanks to One Nation. The Liberals are now calling for a reduction in immigrant numbers, trying to take the wind out of O.N.'s sails. No one trusts the Liberal any longer, they're just about finished. And Labor is in the same boat, floating rudderless in a One Nation sea.

Visited the ASC when they were building the last one and refurbishing the Collins. The guide was saying they decided they wanted them to go faster so they put a heap of fairng on them.

We have seen that recently with the budget. As if they weren"t thinking about negative gearing before the election. Lying pieces of ..... the only reason ON is getting any teaction is because of the poor performance of the major partys. It is amazing how people get stuck into other people without acually thinking they may be wrong themselves.

This bloke does some good video presentations. This one gives a good explanation of what happens when hoons ride Harleys:

To summarise all of the above post, basically I've got to spend less time fooling around on this computer and more time swinging a hammer.

I've estimated there won't be much ratbiking happening until later in the year. There's a lot of shed renovations to finish before that happens, but in the meantime a bit of parts sorting and sourcing is still happening. On the shed/workshop renovation side there's still a fair bit to do. Some steel diagonal braces need to be relocated for better workbench fitment. A couple of windows need to be finished off and a couple more timber wall purlins swapped out for steel. Where one diagonal brace set is to be removed, an existing timber wall frame in that quarter section will be converted to a bracing wall with rods and bracing ply, double braced and insulated. Then a six metre long wall section leading to another shed room will be walled in for bench and shelving space. The steps leading into the other room will be removed and alternate entry to that room sorted. That gets the walls done, so then it's on to positioning existing work benches and building a couple of new ones. After that, the shelving set up. That's all the hard part. The easier, fun part will be filling those shelves and sorting out tools and bits and pieces and setting up the workship equipment. The goal is for everything to have a fixed home instead of the mayhem the shed is now. I'll also lash out and get a sparky to run permanent wiring, lights and power points. I'm over plugging leads in and out all the time. This is a bucket list goal to get the workshop set up the way it's supposed to be. It's been a cluttered half workshop/half storage area for the last eighteen years or so since I built it, and it's been hard to do any major work in it due to all the junk in there which now has to go.

Come and knock on my door we've been waiting for you.

Correct.
