the last thing to mod at the rear end is to mount the exhaust silencer on rubber mounts to stop it rattling cos it was previously bolted solidly to the chassis beam which made it rattle

I marked in white where the exhaust CoG is to locate one of the mounts to keep it balanced

I wasn't a fan of the traditional exhaust rubber hangers cos they're too floppy and move too much.
Decided to get these solid bolt-on Bobbin-type rubber mounts in halfords, meant for rover mini's.

some ppl use them to support the exhaust under shearing or tension load but that'll stress & shorten the lifespan prematurely.
the best way is to keep them under compression, which means I'll have to fabricate a frame to hang the silencer & rest down on the bobbins.

started with these two brackets using the only stainless bar I have available.

welded the lower bracket under the chassis beam and installed the new frame & bobbins

Using the previous mount to help keep the silencer perfectly positioned/aligned to the bumper while I tack weld this new frame in place.
but afterwards I realised the two different vertical & lateral mounts were actually locking each other in place, DOH!

impossible to cut the old mount off with my bulky grinder or dremel, so I slowly hacksawed it off ?

welded it all up

I've essentially created a carry handle for the exhaust lol ?

fits much better and now cusioned on rubber mounts with minimal movement ?
I'd like to add a 3rd lateral supporting bobbin to stop it swaying sideways but I can always add that later on

now I can finish reassembling the rear suspension

 

[pollyp]

undersealed the rear end

wirebrushed & painted the suspension bits

the OEM bolts feature this 1mm thinner shank so that the whole length of the bolt doesn't seize inside the steel bush insert.
the spare bolts I used on the left didn't have this feature

so I machined them with the 11mm diameter feature

rear suspension is now overhauled, assembled & ready to install ? ?

 

[pollyp]

this morning I was sent some spare cg13 pistons I brought from Sir Chris, incase I crack a few ringlands in the future

spent a few hours cleaning & machining the length of each bolt so that there's no exposed threads to rust and seize/snap the next time I wanna take em out. (close to naming each one too lol)
was looking forward to bolting up the axle but then realised the whiteline lower arm PU bushes was very sticky and needs regreasing, so off it comes again

pressed the dried steel bush insert out, machined smooth, regreased and reinstalled the 2nd time

axle is finally bolted on, phew ☺?

accessing the spring adjusters is soo much easier now ?

notice there's 20mm more threads available so it could potentially drop it even lower, but the stiff shorter spring is currently already fully relaxed so one day I'd have to reduce the dampers travel by either remounting it lower on the axle or fit droop limiters

You may be interested to have a look at a similar life’s work restoration of a 89 Golf Cabriolet now available in Devon.

Have a look at picture number 17 of 20 of the under floor pan white restoration. Enjoy.

wow ? would be a dream to have it that preserved ? good as new.

 

[pollyp]

finished assembling the brakes, pan hard, spring covers, drop links and rear bumper

yay it's such a relief to drop her back on all 4's after 2 months of hard work stuck on axle stands during the lockdown ?

she was absolutely filthy with rusty grinding dust outside & inside ?

gave her a much needed wash, much better ?

Wow indeed!

Golf restored to OEM as new (show) standard & picture 17 of 20 is remarkable for fanatical attention to detail that is beyond my comprehension & “bangernomics” cost reasoning when applied to a 31 year old runabout with an apparent 132K on the clock.

time to repaint this rusty strut brace

better ?

setting up the corner balancing scales

discovering a few big issues with my balancing setup:
-these scales are limited to 300kg and with a full tank the front right corner is exceeding it,
-the stiffer spring rates are alot more sensitive to the slightest travel, so 1mm may throw the scales off by few kg,
-all the dampers have this inconsistant friction / binding, due to the seals & pistons, which again throws the sensitive scales wayy-off. (the rear dampers could be disconnected but the front struts can't and they have the highest friction)

all this makes the tool pretty useless ?

anyway, the only readings I managed to get is this. trying to correct the balance with very inconsistant scales was infuriating and gave up.

corner balancing ain't essential at this point anyway cos tbh it looks like trackdays or shows ain't gonna happen for a longg time during this global crisis / shutdown ??

 

[pollyp]

the old alternator has been struggling to fully charge the battery up, only reaching 13.4v so the next morning only has 12v

replaced it with a spare which reaches 13.7v

brought a furry wind sock for the outside mic and placed it within the bumper near the backbox which seems to work in capturing the exhaust noise

went for a test drive on this gorgeous day and wow she feels really good & fun ?

no more rattles in the back. the new tyre & suspension setup feels soo responsive, minimal bodyroll and grips really hard whilst whizzing round tight bends with no sign of under or over steer, probably due to the warmer temps.

mixing the stereo cabin mic with the new exhaust mic sounds great ?

even after greasing, the swaybar polyurethane bush still tends to dry out & bind/stick to the bar which affects the roll-stiffness and made the old bracket on the axle crack from the twisting stress

so I wirebrushed the paint off to loosen it slightly and used dry graphite powder inside the bush rather than goopy grease which tends to be squeezed out under pressure. seems to have worked and there's abit less friction now

catch cans manage to grab 200ml of clear water/fuel vapour from the crankcase after 1500miles since february

Just noticed one your YouTube vids is why I bought a micra instead of another mx5

 

[pollyp]

the tigersealed gauge pods starting to peel off after years of flexing

fitted some normal covers for now while I'm fixing em

ever since I applied red rubber grease to the electric window rubber seals it's barely slides even worse than before cos it dries into a very sticky thin goop

so I removed & wiped the rubber grooves clean and applied dry graphite powder instead. slides soo much more effortlessly

 

[pollyp]

I always thought the throttle cable running over the engine cover looked abit of an eye sore, it rubs against the painted cover and note how the little printed cable mount for bolting the cable onto the rocker cover sits off-set to the throttle body bracket

the normal cable bracket feeds to the front and over the rocker cover

took apart the pulley

drilled the hole round so I can reposition this pulley on the shaft

marking, chopping & welding the bracket onto it's new vertical position

so now the cable sits vertical going from fully closed to WOT

with the cable exiting at the back I can reroute it like this away from the rocker cover

soo much cleaner & neater

rocker cover really needs respraying next ?

 

[Low Rider]

That's why I like DBW, no cable for the turbo to burn ?

Looks nicer Paul but you have gone from one fairly smooth single 'C' bend in the cable to a convoluted 'S', with much tighter bends, something that anyone designing a bowden cable run tries to avoid, more friction and inevitably more likelihood of the cable becoming 'sticky' in the long term.........

 

[plmval]

Quote; "convoluted 'S' "

When I saw the Bowden cable reeling & rolling that rambles round about the engine bay, I wandered far & wide to The Rolling English Road.

"A reeling road, a rolling road that rambles round the shire
And after him the parson ran, the sexton and the squire;
A merry road, a mazy road, and such as we did tread"

Reference; https://www.poetryfoundation.org/poems/48212/the-rolling-english-road

Enjoy.

It could've gone straight over the TB/fuel rail to reduce the bend but I'd prefer to route it clear out the way of everything for better access & appearance.

The S bend ain't that bad. It's bout as tight as some bicycle brake cables and those still work fine with minimal friction.

As for friction, I lubed the cable and there's very very little friction.
I doubt it'll often get as sticky or worn cos it's just light-duty (compared to my very heavily loaded clutch cable) but even if it does stick, it's very simple to just remove & lube the cable annually or just replace it with another bicycle cable.

A brake cable on a bike, and it does not get the degree of use that an accelerator cable on a car does, and does not have to be as free as an accelerator cable, which to give smooth operation, possibly thousands of times a day, has to be really free. I'm sorry Paul this time you have got it wrong. The Nissan engineer that determined the original route for the cable got it right.......A classic case of fashion over form, the aesthetically 'prettiest' solution isn't always the correct answer.

I disagree. a bicycle brake cable experiences a lot more tension & strain squeezing the pads hard against the rim during heavy braking compared to a throttle cable which is just moving a lightly spring loaded flap.

the original route maybe good for reliability etc but I have different needs so I modify it while maintaining function.

It ain't bent ridiculously tight, it's well lubed and it still slides very easily & smoothly whether it's with the pedal or my own fingers. It works & does what I want at end of the day.

Only way to discover what's really right or wrong is by trial & error, by doing it, by R&D.
your standards & criterias are very different to mine.

As they say the proof of the pudding is in the eating, it's not always necessary to try to re-design the wheel. It's not the matter of 'moving a lightly spring loaded flap' but more the ability of said flap's springing having the ability to close again against the added friction of the cable.......NOT a 'fail safe' situation.
My 'standards and criteria' are based on over 50 years of experience, in industry, designing mechanisms in production line machinery, both in the lamp making and automotive fastener industries, where things have to move fast, consistently and for a very high number of operations.

Mmm pudding ? I'll see how it goes. this ain't reinventing the wheel, it's reconfiguring it to a different spec. the spring has more than enough tension to return closed 'provided' the cable mechanism is regularly maintained (which is easy to service on mine). if at any point it begins to show signs of binding at all, it's simple to relax/reroute it another way.

 

[pollyp]

sprayed the A pillars black ?

with the throttle cable sorted out the way, it's time to sort out the tatty faded engine cover.
rather than remove, strip, prep & respray the current cover, I have a spare cover in the garage I could clean & respray from scratch instead

gave it a good soak, scrub & wirebrush in boiling hot Persil

after a blast with the jet wash soaking me everywhere ? it turned out nice & clean

wirebrushed the oxide off every nook cranny

and resprayed ??

I only know soo much to achieve certain tasks, doing my best at making continuous incremental improvements to get closer to the ideal goal.
sometimes I may miss something that another one spots and so it helps to share those thoughts/concerns so I can make better decisions & progress forward.

ever since I moved this lathe rpm disc (cos I used one of the threaded rings for holding the manual hand crank) the sensor was never used

so I printed this quick mount

to position the sensor correctly and now I have an rpm readout

time to wet & dry sand the grill in the sun. interesting to see it was originally from a blue micra but resprayed green twice

primered & painted with only limited amounts I have remaining. still a huge gaping crack I cba to bodyfill but at least it's the right colour now

friend mentioned to me bout a brake bleeder that uses tyre pressure pressurise the reservoir & continuously push fluid through (rather than operating the pedal) while you bleed each corner.

I modelled this cap to seal against the reservoir opening and connect to the tyres with a hose

ooh it's nice when things fit perfectly

The secret with these Paul is to use a spare tyre with very low pressure in it, say 10/15psi or so. Much higher and you will empty the reservoir rather quickly.....

fitted the resprayed front grill along with the badge and she looks back to normal again

went for a drive to buy some stuff.



Wow I'm forgetting how she sounds & feels after only getting to drive kassandra very infrequently every 2 weeks

Her exhaust seems a lot quieter, there's no more rattles, the ride is plush but firms up when compressed, and these tyres have a lot of grip on the warm floor. Back of my mind is thinking this is pretty fast, will my suspension hold? It'll take time to relearn & regain trust in her new setup before I can push hard.

Broke the first bleeder cap as I pressed a 6mm tube into the slightly smaller hole, so I reprinted it with an integrated 7mm nozzle for the hose

got this shraeder bend adapter in halfords to join the hose to the tyre valve

hooked up the front 40psi tyre to the reservoir as a 1st test

can see the pressure pushing up the cap tightly and the struggling single o-ring is hissing slightly, so it ain't 100% airtight yet, but it's certainly effective cos it applies the brakes as though I'm lightly touching the pedal ?

I'll refine the cap with a better seal and use a spare tyre inflated to a softer 15psi instead ?

The seal will probably hold 15 psi Paul, you were pushing your luck with 40 psi, not sure the reservoir to main cylinder seal would be very happy with that either, probably a good thing that your cap seal was not holding up.......

time to freshen up & paint the calipers

begin stripping it down

pistons are still nice & shiny smooth

rear pistons all good, the self-adjusting thread in the middle can still rotate freely, and the handbrake mechanism works fine

overall they're mechanically fine. just needs a good wirebrush & paint

 

[pollyp]

stripped the rear caliper apart

thoroughly wirebrushed all the brakes, primered & painted

 

[pollyp]

all reassembled & looking tasty

 

[pollyp]

ordered some LK0 base coat & laquer from NuAgane to see if it's a better match to the factory paint

I didn't have any right size spare copper washers for the banjo bolts so to freshen up the old washers, I sanded em flat with wet dry on glass.

not to self: don't try sanding thin washers with just fingers cos silly me eventually sanded through my fingerprint till it was bleeding! ?? ouch
it's only afterwards I found that I could sand the washers by using an M10 nut with the threaded shaft in the middle keeping the washer located. learning from painful mistakes ey? ?

fresh brakes fitted

bleeding the whole system with the new tool, works gr8 with 20psi

beautiful ?

I recently had to replace the alternator cos the old one's been struggling to reach 13.3v and charging the battery.
tonight I was checking all 3 of em, they all had the same coil resistances, same good condition sliding contacts but I noticed that the removable rectifier/contact slider is simply connected to the circuit by this spring fork

could it be that this fork and the rectifier end simply oxidises & gets dirty over time which degrades the connection and reduce the voltage output? that's another silly design exposed to the elements.

I'll clean em all up & see if it improves the output reading

 

[pollyp]

cleaning the alternator contacts made no difference.

multimeter still reads:
alternator = 14v
original battery +ve terminal = 13.8v
extended battery cable under passenger seat = 13.5v
nissan datascan = 13.3v

seems like there's a lot of resistance between the alternator, loom and battery.
unbolted the battery extension from the original +ve end and wirebrushed it all to bare metal.
looks like they all had some oxide buildup.

see if that makes a difference

 

[pollyp]

stripped down the 3d printer to fix a few issues.
- the top mounted spool holder pulls the filament over a long distance down to the extruder motor.
this puts too much strain on the plastic filament because it naturally wants to spring back into a coil due to the way they're made & stored.
a few hours after finishing each print, heat from the hot end would soak afew cm up the filament making it more brittle until the bending forces snap the filament making it tangle within the spool.
- the original frame sat too low so I had to roughly lift it up so the bearings for the printer bed clears the desk.

I was gonna just attach some feets to the frame to lift it higher but then thought lets fit some adjustable feets with nuts & bolts too, so I can level it to the uneven desktop & stop it wobbling.

also welded the spool mount to the front so that the filament doesn't have to straighten out as much & over a shorter distance to the extruder

installed all the sliders & wiring

all assembled & working again. hopefully overnight the filament won't snap again while I'm sleeping
