I don't think I'll get up that way till after late sept at the moment, as I've got better things to do at the moment, that don't involve mechanical things

We have declared war on the pigs here Have shot over 150 Now getting some traps as well and looking at baiting. The bloody things are taking the lambs as the ewes are having birth In these larger paddocks here if I go near the sheep they run off and leave the new born behind

If you ever make it up we'll organize a bit of hunting if I don't eradicate the mongrels before'

For our water problem I'm thinking a 6" length of 4" pipe with ends welded and a tap on the bottom. Pass the oil through it, Should work as not enough flow will happen to stir it up in there. May be a bit of mesh over the outlet side.

Here's my final water separator befor the oil flows 30mtrs to the house. Yeah,.. it's prolly a little overdone considering that in 11 years i have only drained a few cups of water off it.

The inlet from the header tanks is halfway up the left hand side, the drain can be seen at the bottom, and the outlet is on top with an alternate outlet to my emergency storage tank to the left. Unfortunately this is an old photo and the alternate outlet is not in place, the small ball valve is an air release and also allows the oil level to show in a piece of clear plastic tubing. the outlet to the right goes underground to the house.

19mm Poly garden sprinkler hose is ideal for long runs as it is cheap, UV and oil resistant.

drop this pipe vertically down into a large bottle (a disused 9kg lpg bottle works well)

this gives you the ability to filter out some 22l of free water from your oil before the lpg tank needs to be emptied.

putting a CAV fuel water seperating filter with a clear bowl after the CAV fuel/water seperator will filter your oil and provide an indication of when your primary fuel water seperator has filled with water.

total cost $40ish for the 2 CAV's, maybe $20 for fittings and whatever it costs you to find a disused 9kg lpg bottle.

Sounds a viable set up. Khos and I are going into Township tomorrow so will see what we can find. I happen to have a few old LPG bottles lying around

You must have one of the most elaborate domestic waste oil setups around

Maybe I could do this with a 9 KG bottle. I had planed to run 12mm pipe but may be to restrictive over any distance.

Also using a gate valve for flow control and its to far back from the drip feed to get good control I seem to think. I was trying to keep it away from the heat. Where do you find those nice tapered valves? As I'm going to need one to get this thing to run right.

It was part of my profession, so I guess it just came naturally.

Yes, I had the same misgivings, the 19mm is only a few dollars dearer, and i know that there is that much less restriction especially where the pipe is exposed to our sub zero temperatures (most of it is buried about 6" down, right next to the fence. An old 9Kg bottle would probably be better than my great big old pressure compensator off a water pump. I only used it because I had it left over after the bladder perished in it and a new bladder was a costly as a new tank complete.

I bought a 1/4' petrol valve from a local garage as it is a needle valve, which I hoped would give me more control. It is OK, but when you reverse the adjustment, you have to allow for a bit of backlash (typically about 1/4 of a turn)

Failing that I would try an instrumentation or refrigeration supplier in the city. A good place to look might be an old discarded gas heater or stove etc.,... just an idea...

I used to get condemned gas bottles off the dealer, they are usually just out of date. He will be legally obliged to drill a hole in the cylinder before he can give it to you, so get him to drill it where you are going to need it, and kill two birds with one stone.:-)

The local Penrith papers have reported pig shooters transporting pigs and releasing them in order to build up numbers to shoot.

Sorry, back on topic.

The mention of using the window out of an oven raises the question - can I use an old wood heater, the type with a windowed door, and modify it for waste oil burning? My next door neighbour will be pulling one out this year and I might be able to score it.

Hmmm,... that would depend on many things, although i can't imagine the result being very elegant. But then again you might know something I don't, (lotsa sane people do). I'd really want to have a good look at it, get some measurements and work out a plan of attack.

One of the main considerations is that it needs to be reasonably airtight, and then we could start to work out how we could fit the two stage burner in to it. My problem being that for 12 years I have only really worked with one plan in mind, and as we all know, "There's more than one way to skin a cat"

Well, it now has a name... Looks like its ready to launch with the legs Khos welded on We're in serious trouble if it does...

Had a few hold ups and Khos has got carried away with cleaning and bling as usual It's not so agricultural anymore.

Have decided to use an old 20 odd gallon oil drum as a gravity feed tank. Couldn't get a separator so have started making one out of a dead direct drive air compressor tank.

At a risk we are going to preheat the oil as was a bit smokey on the last test.

Have heaps of pics but just a few for now
