This has been most instructive. I have always thought that "Terebine" was Turpentine by a different name. This was based purely on the knowledge that the French for Turpentine is Terebenthine.

Lovely work. Pleasure to see someone keeping the craft skills alive.

I would love to be a wheelwright, such a satisfying job. 

(For maybe a year, then I reckon I would find it repetitive, once I could do it)

I doubt it was done like that back in the day. It would be pressed on

I thought the same, thanks for breaking the silence. 
I would expect the outer rim of the wooden wheel to be shrunk on in traditional way. But tyre swaps would be cold pressed like they are with metal wheels.

 Experience is telling me that the only way for us to get it perfect is to strip the rails from the assembly and bend them individually as has been suggested above.

Can you borrow an I-beam as long as the chassis and repeat the process above but anchored at the ends and pushing in the middle, probably with a relatively flexible wooden spreader? 

(Or, turn the chassis upside down on the floor and use concrete anchors as the fixed points)

At least, it could be a crack. 

It looks a bit odd for a crack. It looks like a casting flaw, but a decidedly odd one. 

Maybe build a clay dam round it and see if a pool of <liquid of your choice that won't interfere with painting> drains away?

(Definitely a WW1 find and discovery, definitely military, arguably a vehicle) 

Thanks, seems likely. I am getting a couple of nibbles. 

Does anyone know where all or both the Austin / Morris LD van fans hang out? 

Going through my dad's barn full of stuff I have found an Austin LD engine + gearbox. 

And throwing it in the scrap metal skip seems wrong.

Did find these british tools yesterday.

What the UK calls a "Monkey Wrench" the  Germans call an Engländer. (And one features on their road signs for a mechanic https://images.app.goo.gl/Emb1sbXe4MUzMxXw6 ).

Nice work with the brazing. I wonder if MIG brazing would work for that sort of application? 

(It wouldn't be better, but not everyone has access to Acetylene, and the access is reducing steadily) 

I would be tempted to skim the sealing face flat on the lathe, it looks easy to hold for that.

Just had some sand blasting done. Time for Dad to get out his paintbrush again.

Maybe he should paint the photography table 🙂

 This photo seems to demonstrate the cause quite well.

Do you intend to bend your new ones, for authenticity?

But it still does not explain to me why Peerless used these less common threads

If they were making the parts themselves it might have been as simple as saving faffing about with change gears on the lathes.

BF is now issued as an age related registration to vehicles of the period that have lost their original number or been imported. 

Aye, I know. My Ner-a-Car has one, which is what prompted the question. 

Is that an artfully aged age-related plate? If so, it's well done.

Not one grease pot, Rotherhams or otherwise did I see all day. Perhaps somebody else was hoovering them up before me ! 

I think I know who. 

I had a motorcycle with a centrifugal oil cleaner, it looks like your cranks has the same feature, but rather by accident. 

I suspect that the build-up would never block the oilways, but would only collect in the blind bores under centrifugal force.

Alternatively, you could make something up using Belleville washers or even laminate some 1/4" rubber and flat steel washers.

I am surprised you are not suggesting machining from solid with some extreme thread cutting on a Myford :-)

 Can anyone recommend a one off die spring maker who would undertake this work please?

I have always found Lee Spring to be helpful. They advertise that they make custom springs. 

I got a wave spring from them, they insisted on sending a sample, and when I pointed out that I would only ever need one, they said that was fine. 

I assume from what you say that you have tried putting your parameters in their spring finder?

You could consider buying oversize and grinding down on a mandrel.

Slight wear is visible but we are hoping to re engage this crankshaft for further service, subject to an accurate measuring session.

I would have no qualms putting that back in to service. 

Not that I am any kind of expert. 

But, what fraction of the bearing surface is missing? 2%?

Probably post WW1, but I just saw this on a  Youtube video:

Cast iron crank-case? 

I was surprised by that, so far I have only seen (or noticed the material of) Aluminium (Dennis, for example) or Bronze (FIAT) crank-cases of that period.

I saw that article too, but thought Phosgene a bit unlikely. 

It seems likely that it could be made, though one might expect it to decompose again (200C, again according to Wikipedia)

https://en.wikipedia.org/wiki/Phosgene

And that would lead to the emission of CO and Cl, neither of which are particularly good for you either. Though all three gasses probably beat being on fire.

 Unfortunately it was discovered that this chemical when heated ( like in a fire ) produced poisonous Chlorine gas to the detriment of the operator ! 

I think it's worse than that, the gas created is Phosgene. 

Though Wikipedia suggests that the direct toxicity (to the liver) is just as bad, and it's an ozone-depleting gas too.

It's not the consumption that bothers me, but the tendency to over oiling the bores, making for a smoky exhaust , oily plugs and rapid carbon build up.

All authentic features of a WW1 truck 🙂
