If anyone is interested, I have the plans on cd, a bin and lid and somewhere I might have the sieves. I was going to build one with a mate as my carpentry skills usually only yield logs or sawdust. But he got ill and by the time he was better the kids were too big. Give me a shout you can have it all for the cost of the postage. @bernjb56 ,
