Finally knocked mine up in a Tupperware box :roll: Appears to work fine, but have only tried with a cut down nail 'cos Timstar didn't have the 2 stir bars that I ordered, only the flask :(

I've knocked together the case sides from some 4" x 3/4" softwood that was kicking about. Thats now sprayed blue and drying. I'm using some strong perspex (supposed to be bullet proof) for the top.

I may steal your idea scooby and glue a bit of a rubber mat on the top.

My order is in for a couple of 1L conicals, stir bars and stir bar retriever. So this idea to harvest and re-use yeast, although initially costing very little, has now cost me more than 6 months worth of liquid yeast.

Where are you getting the stir bars and retriever from?

I bid on a few stir plates on ebay but was unsuccessful so decide to put one together, bought the magnets and stir bar other bits had kicking around the garage. Not pretty but does the job

Cheers Chris
I can't see any there of a suitable size? I seem to recall 25-30mm length being the ideal? Or did I imagine that?

That's how long mine is :lol: that positioned the poles over the magnets on the fan. Check the distance between your magnets. I don't suppose it makes to much difference though

Ordered it from here. I was initially looking for 1L flasks but stumbled upon this site that sold everything I was after

Save some money and just hold any old magnet on the outside of the flask when you pitch your starter :wink:
