Default Re: What is happening

One of the best penetrating lubricants available off the shelf over here is Plusgas. No idea what's in it (probably don't want to know!) but it's streets ahead of WD40, GT-85 etc.

I think with the home made mix the volatility of the acetone is actually useful as it assists in helping the ATF which does the actual lubrication wick it's way into threads and such before evaporating - it also tends to do a good job of dissolving old dried up grease, paint etc that would otherwise stop most sprays from getting in.

I've found just neat diesel to work well too for smaller stuff if you can just leave it in a bucket of the stuff for a few days.

Last couple of days have been electrical, though only in fits and starts as I've been a bit under the weather.

One very sensible upgrade on any classic car is a battery kill switch. It's just common sense. Given how rudimentary the fuse protection on this thing is I felt it wasn't just sensible but was essential. I trust the electrical system to not spontaneously combust when left unattended about as far as I can throw it.

So with the rear bulkhead open it was time to get that wired in. Works out nicely given where the battery lives, it's a trivial job to just extend the positive lead to the rear bulkhead of the cabin and to fit the switch there.

This is sited down to the left of the driver's seat, where the "tail" of the seatbelt will tend to wind up - so it will be easy to incorporate turning that on into the belting up procedure. Yes, even in this situation I'm keeping ergonomic planning in mind!

Nice old school switch as well which doesn't look out of place and switches with a very satisfying "clonk" - the necessary tools to bypass it of course will be kept in the vehicle tool kit in case of failure.

Speaking of electrical power, it was high time to get the Invacar its own battery. I'd just been stealing the one from the C5 generally but this had two problems. Firstly being that I also needed it for the C5, but secondly and most importantly was the fact that it didn't fit. The type 038 battery was simply too long.

After a not insignificant amount of head scratching (and measuring what felt like every car battery on every shelf in Buckinghamshire) I came to the conclusion that the original battery is a sufficiently obsolete type as to be hard to find. I think I found one online specialist who had one in stock, but they were asking silly money, clearly the target audience being folks doing a concourse level restoration.

The closest match I could source locally and reasonably cheaply was a U1-R, commonly seen these days in lawn tractors, some bigger motorcycles and small plant machinery. As such they're cheap and readily available off the shelf. Specifications were identical to those in the manuals. The only differences being that the U1-R is slightly more compact in all dimensions and lacks a flange around the base. As such I'll need to make up some spacers for the battery tray and add a strap to secure it. That's really not a problem though.

Here it is sitting in place just before being hooked up.

Looks to be perfectly in scale with the rest of the engine bay.

The other big plus side of this battery is the weight - only 7.5kg rather than 12kg for the next nearest fit. In a car with less than 20bhp, any weight saving can only be a good thing!

Really feel I'd like to get it out the garage again tomorrow...aside from anything else I'd like to give that whole area a good wash down while I've got the bulkhead cover out...though I'll probably just leave that be for now, wait till the weather warms back up a bit.

My *hope* is that tomorrow I'll be able to get the rear axle brake lines tidied up so I can then button up the rear bulkhead again and reinstate the driver's seat permanently, as that's the last thing I knowingly need access there for. Gearbox and differential oils have been changed and levels triple checked, CVT static belt tension is fine, and everything else is accessed from the engine side.

Getting excessively excited and impatient for the first test drive to happen now...
