You have great attention to detail Alan!

The problem with this button is that the thin semi-transparent (for backlighting) fascia piece has fallen off at some point (has the hazard symbol on it) Can anyone suggest a solution on what I could do to make a new one?

My mercedes sprinter van has a huge hazard light button you could chop up to the correct size, the Landcruiser ones are relatively large or just wander round the wreckers looking for likely candidates?

Can you just order a new switch from Toyota spare parts?

Some of you may have seen the electric rear window openers that are available from Japan (See video https://www.youtube.com/watch?v=w-NSu7e0HJU), well I sourced details of the kit but it was obvious that the kit wouldn't work on Australian Minis without a few modifications to the C-pillar and rear parcel shelf. To add to this, the kit was over AUD$300 for what looked like a relatively basic set of parts so you know where this is going ... it's custom time :)

The setup was based around a high torque worm geared motor attached to a shaft and a lever arm.
Image

The first step was to drill out and remove the two pins in the window latch with a 5mm drill bit
Image

I machined some stainless pins to replace the ones drilled out (and they match the chrome colour too)
Image

For the shaft between the latch and motor I purchased a 1/4" flexible extension shaft
Image

I cut this shaft apart to use the flexible core under the main sheath and then machined some small steel couplers for the ends of the shaft. Then using a small piece of steel plate I made a lever arm for the top of the flexible shaft and it was all silver brazed together.
Image

This piece slides over the custom latch pins and allow the shaft to rotate on the same axis as the outer latch pin
Image
Image

The motor was to be mounted to the rear parcel shelf via a custom bracket and positioned so the flexible shaft did not rub on the rear seat or the window rubber.
Image

...and with some of the original sheath trimmed and put back over the flexible core, it neatens up the look
Image

Once the parts were put together, it all looked like this (photo taken through the rear window opening). The black piece at the base of the shaft is a 6mm rubber flexible coupling to join the shaft to the motor.
Image

The worm gear motor is DC, so wiring would be a simple job via a couple of DPDT switches. I used a 10RPM motor which takes approx 3 seconds to open/close the window and would give enough time to predict when the window is completely open/closed and not damage the mechanism by keeping the motor powered on for too long - as there is no auto-stop function.

Here's the bad news ... after spending something like 35-40 hours on this with multiple prototypes and fabricating (I did make all the parts for both windows), I actually decided against installing these openers but thought I'd post the pics in case someone gets inspired and wants to make a set.

There was an interesting discussion on a Mini Facebook group recently in regards to some of the adjustable Hi-Lo trumpets being sold for the classic Mini and their suitability for rubber cones. The commonly sold alloy Hi-Lo's are designed with coil springs in mind and not the rubber cones. Compared to the factory trumpets with a rolled edge, these alloy Hi-Los are a slightly larger diameter and have a flat mating face (no radius machined) for seating the coil springs.
Image

I'd already purchased a set of Hi-Los a few years ago so I decided to modify them to match the factory trumpets. Firstly, I drilled a series of holes around the outer edge of the Hi-Los so I can insert a rod and stop it from rotating when adusting the nut (whilst all fitted in the car). Note that I've previously had the Hi-Los anodised in a black colour
Image

I then machined down the diameter from approx 88mm to 82mm (same as the factory trumpet)
Image

Then I formed the radius to be close to the factory trumpet.
Image

Image

Image

With the diameter reduced and radius machined into the Hi-Los, the spring rate will be closer to a factory set up

After :

In my previous Mini Clubman, I often had an issue with lack of space and how bulky the heater box was and how easy it was to kick and damage the heater duct near my feet. So I decided to add to my work by making a full custom heater box and boy did it take some time to prototype and finish it! Made from fibreglass, it re-uses the factory Mini heater core but instead of the bulky squirrel cage fan, I've used a high flow 150mm PC case fan - The fan I chose flows a hefty 138CFM at 12V and with a noise level of 48dB, it's not intrusively loud.
Image

With some foam glued around the perimeter of the core, the factory Mini heater core was used and fits snugly into the box.
Image

There is no longer room in the engine bay for the fresh air duct so that function has been deleted, as well as the air direction flap between windscreen/footwell. This makes the custom box as small as possible. I've made the second half of the box a fixed split of airflow between the windscreen outlets and footwells.
Image

I then hand-made some 50mm duct bends and some mounts to use the factory mount points.
Image
Image

Airflow to footwells is via some rectangular outlets (one is removable to make it easier to sand and paint)
Image

The size difference between the factory Mini heater box and my custom heater box is substantial
Image

With the demister outlets to the windscreen at the top of the custom box, the tubes are no longer exposed to contact from your feet
Image

I was going to use a new right angle 1/2" heater tap under the dash but after some discussion with some local Mini guys, I was advised that a lot of the new 1/2" Mini taps are of average quality so I fitted 1/2" hose between the bulkhead adapter & the heater core under the dash without a tap.
Image

I purchased a universal 16mm heater tap to match the Starlet coolant system. This was fitted in the engine bay coolant line, between the engine block and the custom 16mm-1/2" bulkhead adapter.

Amazing fabrication work. Keep it going and please keep posting. It's good to have something enjoyable to take our mind of the current doom and gloom.

Very nice fiberglass work, is it just a hobby or do you have a work background with the stuff?

Just a hobby(ish). I used to have a really small side business making fibreglass gauge pods for imports & performance cars but nothing that serious. It lets me look at design solution in a different way now and choose between fabricating in steel or fibreglass. The air filter box, dash panels, heater box, centre console in this Mini are all based around using fibreglass - it's a very versatile product.
