Missed a post here...
A friend on another forum pointed out that there's a perfectly clear photo of the hub/driveshaft arrangement in the service manual which I'd completely missed.
This is helpful in that it clearly shows that it's the version with the fine splined driveshaft coupling I need.
One has now been ordered, hopefully it will be here in a week or two. Once it arrives should be a simple enough matter to get it drilled out to a 4X4" stud pattern.
I also had a bit of a burst of determination in the garage this afternoon.
The wheel bolts I had been using were too long and were fouling on the brake shoes. This was easily resolved though in a couple of minutes with the jigsaw and an appropriate blade. I only managed to launch one across the driveway. Once the threads were chased out I was then able to properly tighten up the wheel bolts to the correct torque without any issues. Even the one with the slightly loose feeling thread which I reckoned would just pull out. Stuck some thread lock on that one for good measure as well.
The jack was then deployed to let me check the wheel was fastened both centrally and straight.
It was. Plus the brake was working properly again without snatching or making any horrible noises. While the hub will be getting replaced in due course anyway, I reckon this will be absolutely fine for a bit of local low speed trundling so long as common sense is used. It's a 400kg car with 20bhp, we're hardly doing hot laps round the 'Ring or blasting up the outside lane of the M1. We've got three high tensile bolts which are as if not stronger than the original studs which are perfectly threaded into the original threads the studs came out of, and one standard M12 X 1.5 wheel bolt with a less than stellar thread. Three known good bolts should be absolutely fine in the short term on such a small car even if the one thread did let go.
While the original test was done at low speed (I only had one wheel jacked up), I wanted to blast it properly to see if anything misbehaved at speed.
Before I could do anything though I needed to unearth the car properly.
I really need to get back to "Mission: Tidy the disaster area of a garage" at some point.
Hey look, she's back in the daylight again...but without any drama or horrible scrapy noises this time.
Having been in the garage since September and basically buried for most of that time she is absolutely filthy. Between sawdust from the work I was doing on the van, oily hand prints (that will be me getting stuff out when working on the Jag then!), and the odd footprint from me climbing past, the poor car needs a wash
The dust in particular is just everywhere.
She hasn't turned a wheel really since September and that can't have been doing anything any good. Wanted to do a better test though before considering leaving the driveway so got the axle stands involved and wound things up until we had an indicated 75mph and held it there for a while. Aside from blasting a huge plume of dust off the driveway no drama. The bolts were checked again and were still tight.
Buoyed by this I decided to take a short run out to get some fresh fuel. Not before driving around our block several times experimentally, then deliberately throwing a bit more force than necessary at a couple of roundabouts and a few emergency stops (the brakes felt a bit wooden as I'd expected anyway)... everything seems fine.
Successful mission completed without incident.
This was the first time I'd had the engine properly up to temperature since I changed the oil and replaced the washer on the sump plug which had been the source of my oil leak, so a good time to see if it had solved the problem.
Much better. Slight weep from one gasket on the nearside but nothing anything like serious enough to worry about. I'm honestly astonished how oil tight this engine is all things considered. Most of the gunk you can see encrusted on the diff casing there is from the gearbox, and as far as I can tell the reason that was leaking was that someone be left the top cover bolts finger tight. I really do need to hit this whole area with the degreaser and pressure washer though. I try not to be too picky about stuff being spotlessly clean but I like to at least make an effort.
As a reward for having successfully made it the 0.8 miles to and then back from the fuel station I decided to continue the tidying up theme. The interior was as dusty as the outside.
I really need to get a wet and dry vacuum so I can give the seat a wet clean as it has quite a lot of ingrained dust in it...plus 212K miles worth of grime from its former life...that could do with removing. Nevertheless it's better than it was.
The rubber floor mat is a bit of a state too, but I don't want to be too rough with that as it's quite fragile. Carpet will be replacing it in due course anyway. I don't want to shred it in the meantime.
Last thing I wanted to do was a bit of tidying in the engine bay. Bit of fresh paint in a couple of places, rerouting of the fuel line and convincing some of the wiring that it actually did want to sit tidily.
Looks a bit better anyway.
She's staying well clear of the main roads and under a self imposed 40mph speed limit until the new hub is fitted, but I think we can call her back in service for the occasional local run. Wheel will be getting checked after every run too obviously.
You really do forget how tiny this car is when you've not had it out the garage for a while!
Nice to be (metaphorically) back behind the wheel again in at least a limited capacity and to have a permanent, proper solution now in the works.

Back to today's update:
Photo heavy post warning!
I really need to hurry up and get the grid laid down over the lawn out the front of our place so I can actually use it for temporary parking when needed...The current automotive Tetris needed to get the Invacar out of the garage (when there's basically no on-street parking available around us due to the school we unfortunately live just round the corner from) takes the best part of half an hour and is a right faff. Just being able to shuffle everything to the left by one space will make things FAR less of a pain.
Nevertheless...after 40 minutes of messing around - made even more annoying when a parent arrived for the school and parked across the drive (again) - we got TPA out, and we went out to run some errands. Have a couple of random "Model 70 in the wild" photos as you might have seen prior to 2003.
One of these things is not like the others...
Ever wanted to make a Suzuki Swift look absolutely massive?
I'd forgotten how much fun this car was to blast around in.
I do think that I need to have a look for a proper Girling brake master cylinder though, I couldn't find the correct type at a sensible price when I originally looked so a random supposedly compatible kit-car one was used (albeit with good feedback...I wasn't relying on random unproven Chinese tat for brakes!)...but I'm willing to spend a bit more now that I know the car is essentially sound rather than a garage-bound money pit. She pulls up perfectly square, but the brakes really do require a good, solid shove, especially for the last 10mph or so (I imagine as you lose the self-servoing effect from the drums as the speed reduces). I think it's something you'll probably get used to over time as well, but it would just make the car a bit less hard work to drive I think. I also know that the shoes used are all old-stock and probably still need to bed in to the drums, so they may well get better with use anyway.
Today we ended up covering just under twenty miles. Including a lot of bumbling around housing estates and basically driving between points A and B via Q, Z, D and 42. This was quite deliberate as I am still treating this as a shakedown period for the hub (amongst the rest of the car given how long it is since the was last out properly...and not forgetting that the only decent journey out of town covered to date was the trip to and from the Festival of the Unexceptional last year!).
Twenty-ish miles covered.
Really need to get that dash pod wired up. Though before I do that I need to figure out what adaptors I need to fit the oil pressure gauge...and probably get a better suited temperature gauge (the type favoured by VW enthusiasts which clamps under the head of a spark plug).
Something I am really happy to see is how clean the oil is now staying. The first couple of changes turned pretty grubby after only a couple of miles. This looks a bit happier I think it's fair to say.
No more visible oil leakage either, even despite one higher speed run today, and I'm sure that the oil was properly up to temperature.
I have to note though that the Halfords VHT silver paint doesn't seem to have been quite up to the temperature that Invacar exhausts run at.
Granted I didn't really do much in the way of cleaning before I painted it...If my compressor was working I'd hit it with the soda blaster, but a flap disc on the grinder might have to suffice. Though I'm not worrying about that just now, she's not exactly going to be in mainstream service when the roads are covered in salt...and when this exhaust fails it will be getting remade in stainless anyway.
I need to get those wires for the number plate light cable tied out of the way too - though they're not actually quite as close to the exhaust as the camera angle makes it look.
When I got back (twice actually as I did the errand runs in two stages), the wheel bolts were checked and were still properly up to torque.
Once I was done with everything I made a quick run out to my usual car park photo spot to grab a few shots to celebrate TPA being back in a running state. Yes the body is still rough as anything, yes she's still filthy, but still makes me smile.
Aside from anything else, the front end looks far better I think now that the black rubber surrounds for the indicators are visible again rather than painted over. Likewise the new number plates look so much better.
To conclude, observations from today:
[] Windscreen wiper works surprisingly well. I expected the dirt cheap chrome thing from eBay to be useless. It does skip a bit at the parking end and I'm not sure how well it would fare at 70mph, but it seems to work a lot better than I expected.
[] Windscreen how appears to be water tight as tested by the random downpour today. Likewise the nearside door. Offside still needs to be rebuilt and leaks like a sieve.
[] Wheel seems to be staying attached. Yay! I will still change the hub once the new one arrives and is machined etc though obviously. In the meantime it will be getting checked regularly.
[] Brakes require a decent shove. Not sure how much of that is "they're just like that" though. My shot at driving the car this was originally used as a parts source to restore was sufficiently brief that I really can't recall how the brakes were.
[] CVT belt needs adjustment I think. There's always been a bit of judder on moving off in this car, but it seems to have got worse recently. I think the pulley change I did was before we'd found the "pulleys must be x distance apart" note in the service manual too, so that will be the first thing I try. This is an old stock belt stored in probably not the best conditions though, so that may be a factor.
[] Actually being able to turn the heater off makes driving on a sunny day far less uncomfortable.
Will try to make a point of getting her used a bit over the next few days and report back on any findings.
