Hi Joe

At last able to get back to you. Thanks for the advice, I had a feeling that a 20 Liter drum to mix the methanol and KOH would be a problem,I just did not know of the extent of the exothermic reaction, and the bloating factor. Thanks for your welcome advice.(Yes, I meant 1.4)
To update I can now confirm the Methanol supplier in the Hervey Bay Area. Just off the main Maryborough to Hervey Bay Road, 2/3 kl ms from Hervey Bay proper, the address is :-

Caltex Australia Ltd
J. L. Keen
Chapel Road,
Nikenbah Phone: (07) 4128 1148

This can bring your supplier up to date for this end.
Prices: 20 Lt --$50.60. 200 Lt -- $250
Needs a couple of days notice for 200 Lt

Also have a Chem supplier in Hervey Bay. Does most of what we need Sodium and Potassium Hydroxide. Isopronal, all the gloves, Aprons sieves etc. His showroom is in the main a catering supplier for Utensils and Chem. Good bloke, does all his own mixing, Only likes to get chem as near to pure as possible - mainly all 99% I asked his to source Methanol for me, great to have everything available right in town. Sorry lost the B---- ^&^$&*()*^%^ Card; will post soonest.
All ready now ,only a couple of fittings, a day job. Treated myself with equipment, Digi scales, Digi PH meter, capillary temp dials, Stainless 300 watt Aquarium heater. I have been thinking its my birthday regularly lately. Will post some pics soon of system put together this time. and ready to go.
Just 2 things: 1. Does anyone have any plumbing fittings knowledge to tell me what to look for. The nylex garden hose type click fittings in brass (3/4") would be great to move the oils around. 2. My old HJ45 has an aluminum fuel tank. Is this a problem for Bio diesel?

Regards Guys
