You could test it by parking one of the Capri’s in it...

 

Believe me I've considered digging a pool size tank before now. You have to be Hellishly careful when acid dipping shells to rinse everything properly. One of the lads had his 280 Brooklands dipped and acid trapped between the panels leeched out later and ruined it. There was no comeback either with the dipping company.

I don't need to bother with an MOT on the mainland any more (> 40 years old) , and £0 historic road tax.

That load of firewood had the rear axle down on the stops.  Good job I only travelled about 500 metres loaded like that.

 

 

And wood fired conversion too. Nice ?

Leaving it in hoping the adjuster screw will loosen up.

 

Tbh it looks like it should be behind glass in a museum!

Mate jokingly offered me his old bath tub the other day. (I'm a known hoarder and taker in of other people's crap! :) ) Though I turned him down I'm rethinking it as I reckon the Focus rear cross member might fit in it.

Adding flames to the fire stoked by @SteamyTea, I've just secured the old bath to be able to derust bigger things! First in will be a MK1 Focus rear cross member once I've liberated it from the associated suspension arms. That's tomorrow's job. Just hope there's enough metal left to make it worthwhile...

Now then how big's the bath to calc how much citric acid...and how to heat? Thinking a loop of Pex-Al-Pex in the bath and a simple loop of black pipe in the Sun to thermosyphon...

@Barney12 Hell man that’s is some serious landrover porn !!!!!!  I rebuilt my first landrover / every nut and bolt when I was 20..... series 2a and now have the knowledge  to pretty much do all the repairs I need from my own humble workshop. Total love affair! Living on an island that does not require an MOT means I can run some pretty old crap and not worry about the madness of an MOT..... though my mainland landy (the grey one) obviously needs to be kept up to spec. The ex Military Police one needs a new canopy now but this is what it looked like a couple of years ago, got a spare axle on the bench at the moment undergoing a FULL rebuild...... again sorry for the thread wobble I will stop NOW ........

I suddenly want a Landover...

 

(Thinking of approaching an owner for a neglected Series 2. Really need to do the Capris first...or more garage space but then I need that anyway).

 

Why no MOT?

Mine is no MOT now as >40 years old.

 

But if you live on certain islands with no RoRo ferry connection to the mainland, vehicles used on the island are MOT exempt.  There is a list somewhere of which islands those are.

 

EDIT  As noted below it is islands with no public "road" and which "do not have a bridge, tunnel, ford or other suitable way for motor vehicles to be conveniently driven to a road in any part of Great Britain"

I live on an island with no official public roads.... there is a traffic  exclusion policy in place so only islanders and service vehicles are allowed over. It’s just dirt farm tracks. 2 miles from my house to the ferry so you need a 4x4. , land-rovers  outlive most of the other vehicles as they just keep on going even when in very bad shape.... the one I use has 250k on the clock and still start on the button and can still pull 3 tons up a loose steep track. It’s needing a bunch of work but that’s a winter job.

So, next candidate for the citric acid treatment. MK1 Focus estate rear cross member. What a pig stripping the arms off it. Cut probably 50% out with a slitting disc. Bless Ford for never assembling any suspension component with grease or anti seize! Got a couple of old baths available as I say if I want them, might do as a container. Maybe paint black and leave in the Sun? However, wondering if making up a "tank" with some Celcon blocks, lining with DPM and then putting a ratchet strap round the whole lot might allow a tank near the exact size and thus save on citric acid powder?

Just hoping there's enough metal left to make it worthwhile. Also a few seized, cut off bolts still in there that I'm hoping will loosen enough to undo once in the bath.

Going for 19:1 for the big bath solution for the cross member 10kg of citric acid ordered tonight.

 

Based on:

4:1 by volume = 250g / 1L 

19:1 by volume = 250g / 4.75L

 

Required volume is 1200 x 400 s 350 so 168L thus just under 9kg at 19:1

 

Should be here Wednesday.

Thinking to mount the bath up on 4 bits of slot together scaffold. Maybe a couple of bits of Unistrut lengthways if the bath feet don't sit right. Fill it up with 160L water. Then a quick homemade solar thermal panel o/of some leftover Pex-Al-Pex. Got a scrap OSB board I can mount it on and paint black. I could really go to town and frame it, glaze it and even insulate! Let it do its thing and thermosyphon. All out of scrap of course :)The first worry is maintaining 65degC?

Why?

 

Are there not some lamp posts that need counting, or some baked beans that need eating with a cocktail stick, or something?

 

Perhaps I will never understand..

Why do anything? Keeps the old grey matter ticking over. The day I stop thinking...or is that over thinking?

 

Why collect bottle caps, why start making a table with them set in 2 part resin?

One of my pieces I made as an apprentice. This was rusted solid, stiff and otherwise fit for the bin. Came out of the bath yesterday and tbh I should have oiled it straight away. A few minutes back in the tank will get rid of the flash rust:

(I even made the knurling tool that knurled the screws. Trying to find that).

I am getting a prehistoric Arthur Dent feeling about this.

 

Confirmed by yesterday’s Cricket.

 

I also have a couple of pieces I made as part of my EP-something, including a measure-twice-reminder toolbox with the handles welded onto the wrong end of the sheet of metal that became the lid , so every so often you get a reminder not to make that mistake again when it barks the knuckles.

Our family's last Ford was a Cortina Mk III L reg, and that *didn't* handle well.

 

Which was why the next one was a Mk I Fiesta15 years later when I was desperate, bright yellow and known as Felicity by its previous owner. Sort of car that Florence from the Magic Roundabout might have,

 

Though to be fair a Ford Cortina was not much competition for NSU RO80s, which followed it.

 

When it was stolen they bailed within half a mile.
