I am reminded of a quote I hear Steve Summers use on YouTube when warming nuts with oxy-acetylene: "It can't be seized if it's liquid..."
-
Another vote for this. It's a fairly standard way to remove inner races.
-
That's a good point. At the moment the effect of the bearing taper is to squeeze the inner race down on to the shaft as the wheel is pulled.
-
Maybe a mag-drill and a carbide drill bit to drill a hole axially through the inner race. (Spark erosion with a tubular cutter to do exactly the same thing would probably also work, and would be more dependable when it broke through. No chance of adding a broken carbide drill bit to the problem.) Maybe someone hires these out? https://www.eurospark.co.uk/product/tr100-broken-tap-remover/

I don't think that you _need_ to quench when annealing copper. It is just that you _can_ as it does not have any hardening effect, it can remove some of the scale, and it saves waiting for it to be comfortable to handle again.
-
Possibly a choice of compression ratio, if the difference is in the crown-to-gudgeon-pin distance rather than just a longer skirt.
-
I have two views. Just like you 🙂 I stand ready to argue against all stated opinions on both sides.
-
Alldays and Onions also made motor cars briefly. One of my dad's favourites in the game "name all the car marques beginning with A, then B and so on" The commencement of the game is normally announced by the word "Allard"....

Spotted on Facebook Marketplace: https://www.facebook.com/marketplace/item/600949781352415/ There is a suggestion of Dennis, but if so it's not one I recognise. Note the handbrake and quadrant re-positioned and re-purposed(?).

It wasn't this company, but they might be a useful source: http://www.rolledrings.co.uk/ My impression is that such rings are a product with low setup costs, and so they might actually be affordable in low volumes.
-
As a kid I recall driving past a seamless ring rolling mill somewhere near Sheffield and my dad explaining the process to me. (He worked for David Brown, who use forged rings as the starting point for some of their gears) I have seen variants where the mandrel is pushed through a solid billet, too.
-
That is an awkward way to say 1/2" 🙂 If you want I can put a dome on them in seconds with my CNC lathe. I need to do at least one for the Fire Engine anyway.
-
The 'strange aluminium spacer' also seems to have a crack through to one of the holes. I wonder if that will cause a weep? Maybe some sort of penetrating sealant (Captain Tolley's Creeping Crack Cure?) might be worth trying.
-
A YouTube video of an upcoming clearance auction seems to have a drill similar to that from the mobile workshop: https://youtu.be/ojGfR-A_FW4?t=748

Spotted on YouTube. 1920s bus with 1930s body. Well composted.

The Plano-mill might be salvaged, if anyone wanted one, as the main slides are (largely) protected by the table. Machines always look more rusty in photos/video than in RL, too. My current lathe looked rusted beyond use in the photos, but polished up fine with a bit of wire wool. Though I would not go so far as to assume that the same is true of the lathes in the video. FWIW the creator of the video knows more than a bit about lathe reconditioning, he is nearly finished with a complete restoration / re-scrape of a Holbrook. -
It's easier to make hex-head bolts out of hex-head bolts, and they are available in the same grades as cap screws.
-
For the flywheel bolts of our N-type (which have broken more than once) I started with bigger-than-needed HT metric bolts, and machined them all over. It's an easy way to be sure that you have the right sort of steel and the right sort of heat treatment.
-
Not always, on our N-type the filler is under the passenger side seat, though the fuel outlet is on the right hand (carbutettor) side.
-
You appear to now have two adjustments? The infinite worm-drive bolt and the finite vernier coupling?
-
I think it might take a thermocouple to figure out which way to go. Possibly richer would run cooler?
-
And maybe different timing.
-
Aye, they didn't have Catnic Lintels in 1915. In fact not until 1969: https://en.wikipedia.org/wiki/Catnic
-
I couldn't resist trying to get exactly the same perspective. This is as close as I could get on Steetview. https://goo.gl/maps/yHurwMjyhD7Tba8t6 It looks like the bus stop is in exactly the same place. I am not sure what we are seeing to the right of the bus stop in the original photo.
-
But I doubt that is what is actually in the rear axles, as a different manufacturer is mentioned. (I have something of an interest in David Brown, my late dad started with them at 14 straight out of school, and left 49 years later having worked his way up from fitter, via the drawing office, to service manager and senior commissioning engineer)
