Why can’t the casting be welded by a competent welder?

It could. but then it’s not original. If it were mine I’d weld it, or failing that have a tame machinist knock up a new one… but I’m thinking someone might have a box of NOS ones laying about wondering what they are..

Wow ! Last one flying ?

I used to see the Airbus ones descending over Stockport , picking up the outer marker on approach to Manchester in 1984/85

Yup, the others are all in museums.

Of course you can learn a little bit from reading and then you can learn a lot from making a mistake, which is a tough but good school.

It’s much better to learn from the mistakes of others, cheaper too & sometimes rather entertaining. 😉

Just watched the video, didn’t need subtitles or a translator as my step dad is from Skipton 🙂

As for the *posh* 3M roloc discs for stripping:

Before I was involved in aviation I worked a couple of years on a project connected with Geldofs famine relief fiasco. It was soon discovered that I had a knack for blagging stuff for free. The previous blagger would call up some business to whinge and/or whine about what we wanted & barely got a damn thing.

I was a bit more direct. It was more a case of “Right, we need this *whatever*, You have some, send one to us. We’re not going to pay for it, but we will be eternally grateful. We have shit to do. We want it here by Friday or early next week”

So if I were there, I’d call up the local 3M wallah & just say:
“We need a box of brown & a box of red 3M roloc discs, 50 count of each color, 3in diameter & a couple of 1/4in mandrel doodads to attach them to our die grinders, one 3in, one 2inch*, by the weekend. We’d prefer genuine 3M, but generic is ok.” (Yorkshireness will be an asset here)

This approach seems to catch them off guard & before they can think about reasons not to give you stuff, they just say “Righto, what’s the address?”.

Once you’ve blagged the first want/need from whoever, they will be on the hook for the entire project. I would start at the top & call 3M direct… maybe track down the local autopaint/autobody supplier & give them some grief too.

Called up one place for a Bedford TL clutch, gave them the spiel. Big box arrived on a pallet the next week containing two clutch assemblies & a brand spanking new 5speed (Spicer?) gearbox I hadn’t even mentioned to replace the 4 speed the truck originally had.

Just be sure to clear the blaggery with YAM if you’re going to invoke their name when putting the hurt on whoever has what you want/need. Another thing: If you have access to a tame woodbutcher & engraver maybe give the people you just worked over a *gratitude plaque* to hang on their wall, or maybe promise to put the company name on something at YAM once it’s completed etc. People like something in return for having their ear bent.

Just go for it, don’t ask for stuff, just point out they have it, you need it. The first time I did it I thought the result was a fluke. It wasn’t, I can’t recall anyone saying no. 🙂

* for the 3in discs once the edges are worn down a bit.

Off the top of my head; other types which used the same blade, but cut down to their requirements were: C-54/DC-4, Hellcat, B-24, B-17, DC3/C-47 and the Lanc (though these blades were made by de-Havilland under licence from Ham-Stan to the same pattern), along with the York/Lancastrian.

& modified DC3/C47 blades get used on Hurricanes. We shipped a couple of sets to the UK some years ago.

Nope, a fibre wheel.

3M Roloc discs?

The amount of blood was out of all proportion with the pain & the size of the hole I was leaking out of. It was rather bizarre. Been to look at the 33 today, most of the paint is blistered from the hangar fire.
