  1. Hi Oldlady, Thanks for your suggestion. I actually live in France, miles away from any libraries. That book is available but expensive, which is a shame as it looks like it might have some interesting things in it. Perhaps I can find a soft copy on the net. Your friend's system sounds like what I'm thinking about. If you have more details, I'd be interested. Clay is heavy. Anything you can do to avoid manhandling it too much is a good thing. I am thinking of a metal trailer which is water tight that I can fill with clay using a mechanical digger and with water. Then I need to let it soak and agitate it somehow. I can use a garden rake but it's still hard work. Then run off the water via guttering(possibly fitted with various sizes of filter) into another tank to settle. Previously I just filled a tank and agitated with a rake and then used a saucepan to transfer the clay-bearing water to a big bin through a filter( 60 mesh+panty hose) to get rid of twigs and vegetal matter. Even that was quite a lot of effort. I have not tested the clay as I don't have a kiln yet. I was going to ask a local potter to do it for me. I imagine the testing involves biscuit firing a number of test pieces at a range of temperatures in order to see how it stands up... literally. Is there anything else I should be looking for in the tests? Cheers Andy
  2. Hi Forum, I am looking for pointers to good systems for processing dug clay. The clay I have looks good but to prepare any reasonable quantity takes time and effort. So before I move to preparing larger quantities I'd like to see how people do it. It will be a low-tech approach. I have read that people use tanks containing water and raw, unwashed clay which is soaked and agitated to put the clay in suspension. This clay bearing water is then run through a system of troughs and settlement pools. I am hoping that there are some books/photos/diagrams/detailed descriptions showing what an array of of this type might look like. How and where is organic material filtered out? If there is any way of getting gravity to help move the materials that would be good. Ways of agitating the clay which don't consume all your energy? I have heard it said that it is better to weather and dry the clay and then crush the clay before rehydrating. But I have no idea why. And drying and crushing takes time and energy. Any cheap mechanical aids? I expect to be processing about a tonne of raw clay in one pass. Thanks in advance Andy K
  3. Hi all I have a similar problem. I am trying to remove the wheelhead from an Alsager wheel by J W Ratcliffe & sons of Stoke on Trent UK. It's probably frm the 70s and I cannot find a manual. The wheelhead is on solidly. I can lift all 70 kilos of the wheel by the wheel head. I cannot see any locknut on the shaft anywhere. It is a little rusted just under the wheelhead itself and it maybe that it is threaded on and that there is rust holding it. I cannot turn it either way though I have not tried to force it. Does anyone have experience of these wheels or any other helpful info thanks Andy
