Defender additions

[Bundalene]

Just finished installing a stainless water tank plus axe/shovel holder to the Defender - took a bit longer than I planned. The water tank holds 45 litres - yet to add a breather. (Newer shovel coming before the next outing).

Always good to add improvements - gives more storage space inside.:D:D

Looks very nice.

On a separate topic: Are you involved with the "Son_of_Bundalene" Land Rover eBay shop that I was browsing around earlier today?

Yes, Andy is our son.

[spudboy]

Uh - OK, I thought there might be some connection :D

[dullbird]

i'm sure erich hasn't got random son's lying around the country.....:):p

[dmdigital]

Erich you have too much time on your hands:p

Very neat job!

I'm not sure about the filler at the back though, has it got a quick connect fitting?

Does the axe or shovel handle move against the back quarter window?

I bloodywell hope not !!!

By the way, what have you been up to today in Gove???

The filler isn't finished - yet to add a breather and an easier opener. The shovel handle is locked against the roof gutter and the axe is fixed tightly and clear of the window rubber by about 20mm - should be OK even on the corrugated Gove roads;)

Is that a valve for a poly-air i can see on the back? How do you find them? I'm currently tossing up whether or not i should buy em. Thanks!

[dullbird]

today we went to the arts centre in yirrkala and brought our selves some aboriginal art......the art work in there is just amazing, i just wished i had more money to buy stuff

the painting we brough was painted by a young girl so it had no explination or anything but we have her name so wouldn't mind conituing to buy her work.
we then got driven around to see the various parts of the mine and refinery...this was after spending the moring at the lagoona taking a few piccies of the various birds down there. oh and derek took us to shady beach. that was really pretty also.

so much of this place just looks like an untouched unspoilt paradise

then it has been checking the car over and stuff, and twoing and frowing with the guy who sold us our HF as we cant get it working, but since found the problem.
so we are leaving in the morning.

yesterday was good also got shown around town and stuff met up with a few landy owners for a BBQ, and all just very pleasant.

Hi, yes it is a poly-air valve. I find these excellent when loaded up, towing a boat. These allow us to level the rear of the Defender. Empty we run the poly-airs just under about 10 psi and when towing about 15 - 18 psi.

This is the 3rd vehicle on which we have had airbags.

Cheers, Erich.

When you get back to Sydney give us a call and we might be able to trace the artist - maybe even put you in touch.

Have a safe trip out on the track.

Cheers, Erich & Sheila.

looks nice and practical..but that close to exhaust muffler setup..you just need to drop in a few tea bags and have a hot brew when you stop......

"so much of this place just looks like an untouched unspoilt paradise"

It is an unspoilt paradise, and much more so further out of town.

It's a shame you couldn't stay longer....next time maybe.



Enjoy the rest of your trip.

Safe driving.

Actually I am not sure about the water temp yet - there is a 10mm air gap and air is a pretty good insulator. If the water does get warm I will either remove the rear silencer or insert an insulator ( or just have a cold beer instead) :p

We went for a drive down the coast on Monday (about 200kms) It was quite hot during the day and the water in the stainless tank was cool as.

I can confirm that the water does get hot on long drives :P we have a water tank in the same place although our tank is plastic but i would not have thought that that would mattered.

Did you buy or build?
If you built can you post the dimensions etc.
Good job.

Hi, This water tank is home made, 45 usable litres. The dimensions are on the photos. If you make one, probably advisable to make it about 25mm narrower as you don't have to remove the side ribs as one of the photos shows.

Also the fill point interferes with the number plate position. This has been moved to the other side to make way for a shovel / axe holder.

I have taken a few pics as the installation proceeded. If you want more info Please ask and I will post it

Inside lip of guard and flare had to be trimmed to make way. I also covered the wheel arch side of the tank with sound deadener.

Another bump for Travelsick on the water tank question.

Nice but doesn't the exhaust heat the water to a nice warm temperature ?
(Good for coffee I guess).

Keep the shovel - it has "character" like all good Defender bits should !

The water temperature is no higher than ambient. The air gap with the air moving through the gap makes for an excellent insulator.

We usually keep 2 litres of water in our fridge, which we top up in the morning.

I've just installed a water tank in exactly the same location and am/was worried about the effect the exhaust might have on the temperature of the water. Just out of curiosity, what had you planned to use as an insulator if the water was being heated up??

[Bush65]

Heat transfer obeys laws of physics. There are 3 modes of heat transfer:

1. Conduction - will not happen because the dry air between the exhaust and tank is a very good insulator. Adding another insulator will not achieve much unless it is much better than air - unlikely, but don't let me stop you. Insulation combats conduction.

2. Convection - heat is transferred to the air in contact with the exhaust, which becomes less dense and rises to where it contacts the surface of the tank. If the heated air is dispersed by vehicle motion or wind this wont be a problem until you stop, but then the exhaust starts to cool - this is where an insulator against the tank may help as a barrier.

3. Radiation - the dominant mode of heat transfer in this application. Polished stainless steel or aluminium is a very good reflector (note that dullbird's black plastic tank does, but Bundalene's stainless tank doesn't suffer from water being heated.

A reflecting shield close to the tank can reflect a lot of the radiation and the air between the shield and tank surface will serve as insulation - just my 2 cents from someone who has has done the calculations to apply this to industrial applications from time to time and observed the results.

The tank material then has to transfer heat to the water. Stainless steel conducts less heat than plain carbon steel, which conducts less than aluminium.

Heat transfer and insulation problems differ between short and long periods of time. Over a long period (we may often be driving for long periods) the temperature will rise across the thickness of insulation and heat transfer will increase. In this situation it is much better expend your effort/$$ to reflecting the radiant heat away and to disperse (ventilation and air flow) air that is heated by the exhaust, than to add insulation.
