You're very kind but this place is no trouble to maintain really 

Absolutely 100% agree that this place should always be free of advertising and never subscriptions to see the "good stuff".  Even if it gets really busy and my little server isn't up to it, better hosting doesn't cost much and we could keep it running easily by member donations - which would go a lot further than they seem to on VOD.

Interesting that Jules posted on VOD about lack of posts, I've stopped checking regularly which is very unlike me.  It's a bit thin on interesting things recently.

Bit thin is quite an understatement, I tried to have a bit of a dig a while back about new members selling car, (when I mean new I mean first post car sellers!) Got a good kicking for my troubles!! Seemed to me, bearing in mind I know none of the big fish on VOD, that he was a mate of a moderator so everything was fine especially as it was an old merc.

I do find the one eyed  goings on a little annoying!

Well their loss.  Thought your post about indian oil and mucilage and gee was very interesting.  Given our historic failures with Chinese oil too, having a chef on board can only be a good thing.

Todays "todays post" is the shortest ive ever known on the VOD,not sure of the reasons why.
Without getting into the take on the VOD discussion it would be nice if this forum was a little bit busier,just so there were a few replies each day,it seems to go in fits and starts.
I think we need to have a new members drive,im trying to get Nathan to look in and im trying to get RM to post up some of his new veggy ideas

[Tony]

Just looked and you're right - less than a page.  Very odd for summer - there also seems to be very few new sign-ups, given this is "make hay" season for biodiesellers.  Perhaps the fierce commercial oil competition is killing the homebrew market, or everyone that wanted to try it has realised it ain't that easy.  Could be the homebrew biodieseller is a dying breed (beyond the ridiculously hardcore few members).

I must have missed that thread.  Is it something we could put on the wiki, we have little information on oil sources and types.

Should be recorded somewhere in the wiki for posterity.

Is this something we could test?

[Greenchef]

I've wracked my brains with regards to tests on these oils and their emulsion properties, although purely by eye, I am convinced that more emulsification occurs with Indian oils.

I nowadays, with the beautiful no titration method, go from 7% water wash to 20ltre water pump wash (misted in!!) and rarely have any issues with soaps or emulsions. However when Indian oil is used I'm sure I always get a bit of a glupy white layer.

The problems with trying to establish quality tests are the huge variables and time requirements. (is the white stuff soaps or emulsion, oil acidity, heat, time, mineral content of water Agression of the mixing etc etc?!) All a bit beyond shed science, well my shed anyway!

I used to love reading posts in VOD forum. It has been going down hill for a while. For me RM's departure was the final nail in the coffin

So this is where you're all hiding!

A good portion of my collection comes from indian takeaways, but I only run on wvo not bio, would this affect me?

Hi Nigel
Wellcom to the wiki,
what took you so long.

[Greenchef]

Hi Nig, great to see you over here, don't think it will make one jot of difference to wvo use!

However have tentatively started research into my theory. So far I have emulsified soya oil, Virginie rape, normal rape, and olive oil all at ambient temps. (Method 50/50 oil to water Blend with stick blender) Once emulsion is formed simply leave to stand. Emulsion with olive oil drops out in an hour soya a bit longer virgin rape still mayo after several days normal rape half split with some emulsion remaining.

Next job is to make bio out of all the different oils and start the emulsion tests over again with glyc. Drained raw bio and then washed bio.

To tell the truth I've ground to a bit of a halt awaiting the out come of Keith and Julian's acid tests. Mine seam a bit pointless if you can negate the problem with acid.
(Something I'm struggling with though is in commercial kitchens we use acid with mustard to enable the emulsification of oil)

I guess it could be because we are dealing with Bio and not oil at this stage.

[Greenchef]

Absolutely! But if mucilegens survive processing then the problem still remains. Guess its lucky that most oil we seem to get is ktc soya, ie source from beans not seeds!
