The thing about Lotus and other small British companies is that drat near all the little bullshit components comes from somewhere else, it's just a case of knowing where. Looks like it has a remote servo on the brakes, is that standard fit?

It's a bit of a rubbish TBH, but just something that has really annoyed me since I heard about it due to being interested in DeLoreans. They used a fairly small diameter (7/16") bolt in single shear into a metalastic bushing in the chassis as the pivot. The bolt itself is unnumbered, but see the areas of components 1, 2, 3 in this image:  It's not actually that bad in such a light car, but they used a very similar design in the Esprit, and then in the DeLorean, so you're getting heavier there, which probably contributes to why they seem to have a reputation for bending/breaking on those. People seem to sometimes "solve" this by going overkill on the bolt material, but really, it's a problem that shouldn't have existed. They could have made a bracket with the bush axial onto the front end of the trailing arm and a big flanged nut/washer on it, or they could have engineered a small bracket to make it a double-shear mount and had the bushing in the end of the trailing arm. Hell, for the latter, they could probably have bought in bolt-on leaf spring cast mounting hangers from a light commercial to do the job easily. But instead they hung it out there in the breeze on that 7/16" bolt and it's just wrong to me, and something that would cost very little (in cash or added weight) to get more "right", especially when making heavier vehicles. I'm not normally one to get too worked up about the whole "single shear is baaaaad, man", because it's often still nailed together well enough to be a moot point, but, well, I look at that example and I don't bloody like it. You'll notice that on both the replacement chasis you've pictured, it's one "feature" that's straight out the window. InitialDave fucked around with this message at 10:51 on Jun 24, 2017 |

kimbo305 posted:Would that potentially place more stress on the parts of the plate where the bracket is bolted in? Compared to the (maybe) wider spaced bolts around the bushing? This is the kind of bracket I mean, this is a folded/stamped one from a Ford F150 I believe:

I can't find that specific test, but there's a contemporary one from Autocar of the 4 speed version that's similarly detailed.I kind of miss that level of detail in magazines and brochures, some stuff about modern cars is bloody hard work to find out (e.g. ok, it's got AWD. How exactly is it set up/how does it work?)

Not sure they look like starter ones, seem very lightweight, like they're from a power tool or something. If car related, it's possible they could be for something like the heater fan or wiper motor too?

Fo3 posted:I don't even know how zenith/strombergs or su type carbs even do chokes. Those types of carbs I never worked on, does anyone know? An SU carb still has a "normal" throttle butterfly, and still admits fuel into the carb through a jet, the same fundamental mechanics of any other carb. The big difference is that the jet on an SU is adjustable, it's basically a bigger hole with a tapered needle poking into it - pull the needle out, the jet effectively gets bigger. The dashpot is a sealed chamber, containing a piston connected to a cylinder that pokes out into the main bore of the carb, restricting it. There are tubes connecting either side of the chamber above and below the piston the the carb bore on either side of this restriction. The throttle butterfly is downstream of this. If you open the throttle, the low pressure area behind the restriction also creates a low pressure above the piston in the chamber. This is relative to the pressure below it being linked to atmosphere. So the piston moves up, taking the cylinder that pokes into the bore with it, effectively enlarging it. The oil-damping system in the dashpot is "one way" - it damps the piston coming up, but allows it to drop straight down when you close the throttle. So by the above, you've got a variable-size carb, in effect. Now, the aforementioned tapered needle that restricts the jet. That's attached to the bottom of the "restricting" cylinder, so it moves up with it, increasing the jet size as your carb gets "bigger". There is also a mechanism to lower the jet itself away from the needle on throttle openings, so you get that throttle-opening enrichment you need. The "choke" doesn't really deserve that name, as it doesn't work by restricting airflow, it artificially does the "jet drop" function to give a larger jet for the cold start enrichment. BloodBag posted:Wasn't it the original mini that had the dashpot in the carbs share oil with the engine so if you'd change weights the carb response would change?

I think the solenoids on SUs operate slightly differently, cutting off the air bleed into the float chamber to stop the venturi effect being able to draw fuel through. Might not be correct on that, mind.

kimbo305 posted:I don't get why they decided to make the car so true to life, but I can definitely appreciate it. about stuff.It's similar, for example, if you watch Shin Godzilla: They specifically label on screen all the military kit and trains that appear. The Japanese have elevated being shamelessly nerdy about this stuff to an art form. Guns are another thing where you'll find an incongruous level of detail being put in.

Ah well, that's a shame. Will you look at another interesting toy once you're settled into the new place, and maybe able to scope out storage somewhere?
