That makes sense. I reckon once the envelope stuck to the inside of the truck or mail box it would be tricky to get it off in once piece.Hoops said:
The price on the courier bag sounds a bit rich, I guess if you can arrange a group buy you'll be right.
Just ordered the bits for my build. Scored a 120mm fan from work and have an old power supply at home.
Ordered some magnets, pot, switch and enclosure that I'll pickup tomorrow.
Ordered a couple of stir-bars from the place you recommended sosman. But jeez they kill you on the courier fee. $14.95 postage/courier fee from Melb to Sydney. They are also out of stock on the 50mm and 70mm stir bars. The lady I ordered with checked with their supplier and they had them in stock so should have mine in my hand probably mid week ( as it is a long brew weekend this weekend).
I checked my two growlers I got from the US on my last trip and they have flat bottoms. They are 1/2 gallon growlers so should be a good size for this application.

I have another idea on this project.
I have used the 1.125litre Johnnie Walker bottles as a starter vessel in the past and have noticed that when you want to rouse the yeast you can do so easily by just spinning the bottle back and forth.
This is because these bottles are square and so you get heaps of turbulence in them just by rotation.
So I have just acquired (yet to be delivered though) a couple of those glass 5 litre whisky bottles that they dispense from at some bars. (they just throw them out!) I was going to use them for building up cultures to split and store but this thread got me thinking. You are all wanting more capacity and are worried about other vessels not having a flat bottom for the stir bar.
My thoughts are that these square 5 litre bottles could be used in the same way as the stir-plate but without the need for a piece of stuff in the vessel that you might tip into your fermentor. Why not just make a turn table for the bottle to sit on and either set it up to oscillate back and forward or even just put it on a timer to switch it on and off in the one direction every 30 seconds or so. Result would be constantly agitated starter wort. You can easy get a bung to fit these so I reckon it could work.
Once I get them I might gadget up my idea and report back. Ahh more gadgets.

The cheapest option would be to get a fan out of an old PC. See your IT department at work. They would probably have an old power supply kicking around off an external modem or similar device too.
Beers,

For the fan, rat an old PC power supply. You friendly local PC store probably chucks them out and quite often the fan is still ok.Dazzling said:
For a power supply you will need to rig up some variable voltage - a simple circuit with a pot and 3 legged voltage reg powered from a plug pack should do it.

I just used a plugpack and wired a 500 ohm pot in series. It saves all of the hassles trying to regulate power as it doesn't really need to be for the stirrer. I have checked all the maths and it is well within the rating for the pot for plugpacks up to 12 volt.
