I built one using 3/4 and 1/2 inch copper, readily available from Bunnings or any other hardware shop.

Here's a pic. 2338
It consists of 6 pieces. The 3/4 tube, 4 pieces of 1/2 inch tube, and 2...

Have a look here.

Condenser, heat exchanger ..... same thing.

Tilly, I don't think you have upset anyone.
Just your last 3 posts are blank. not sure how they look your end, but they are blank to me.

I think RONA has got Tilly.

Actually you should water it down. High concentrations of ethanol are not as effective as when it is a bit weaker, so I read.

What you have there from Bunnings is Sodium Hydroxide. NaOH. Potassium Hydroxide is KOH. It will do the job, but remember the quantities need to be varied. If you want KOH look for chemical...

On the outside it looks all nice aand fuzzy.

BUT they are not talking about biodiesel. The are talking about CRUDE PALM OIL. This may not be such good news.

First thing I'd be doing is check the oil level.

In another life I used to live in a red dirt area. Never heard anything along these lines. Usually anything from the red dirt was preferred over anything from the coast It may have come from a...

So you mean I can use your method and make biodiesel from my 200 litre block of lard without first having to heat it until it melts?
I find that totally amazing.

Can't wait to give it a crack...

You are wrong Mark or do you find pleasure in peddling misinformation?

1 heating step, then
1 cooling step.

Go and actually read the instructions before having a hissy fit.

Oh my bad. I see where you are now. That fat titrates very high and would be a problem right from the start.

I have never used anything that high. It may not do what you want it to,...

With all due respect, Are you just chucking darts at the wall to come up with these numbers?

You would need 2...

If I where using NaOH I would be using around 5g as base amount. If you are doing 1L test batches then as a test you could do one at 4.5, 5 and 5.5 and see what works best for you. I have found...

And not to mention the NaOH/KOH you save by not using more than is required.


I don't believe there is such thing as a foolproof anything in life, because no matter what along will come some fool...

The point is 2 kg of sugar in a 6 cubic metre truck load of concrete is enough to stop it from setting. So if you think 20 litres of byproduct would have no effect, then maybe you need to rethink it.

You really think so?

Well try this next time you get to doing some concreting done. Chuck a 2 kg bag of sugar into the back of the truck and get them to give it a real got mixing. You should...

tits of 8 are a bit high for my liking. Dig a hole and bury it.

My thoughts is it is not a blocked hose at all, but rather the piston in the master cylinder for the rear circuit is stuck and not returning. I would start by loosening pipe to the rear brakes right...

I would not want to be counting on that alone. Oil in the pump= slippery + lots of back pressure ???? Might just be enough to make the pump spin backwards and you lose oil pressure.

Provided thosw items are rated or the temps they may encounter. The pump at 1-4 litres per minute would be around the capacity I would expect you would need.

ou would also want a non return valve in the priming pump circuit so that once you start the engine and shut off the priming pump your oil pressure does not bleed off through it back into your sump....

It's getting that way that you don't have to think at all. Just get an app to do it all for you.

There is a very simple reason your engine sounds different on WVO. It has nothing at all to do with lubricity of the fuel.
A simple test to prove it is when running on dino fill an oil can with ATF...
