    Metal banding straps from crates works for me - I don't think they're that ugly.

    ayjay got a reaction from irenepots in Finding Bats To Fit Shimpo Rk-2 Wheel Head   
    I make all my own bats, I also had to drill my wheelhead to fit bat pins: I first made a template with a 3mm hole at the centre to allow me to centre it on the wheelhead in which I'd also made a 3mm hole at the centre, a 3mm diameter masonry nail serves as a locating pin.
     
    I made the holes for the bat pins asymmetrical: one of them is about 90mm from the centre and the other is about 120mm -  my bats can never be put on the wrong way cos it would be very noticeable.
     
    I've obviously kept the template so that any future bats can be drilled out to the same dimensions, a 3mm hole at the centre and a couple of clamps and it's ready to go.

    ayjay got a reaction from Chilly in "aggressive Cleaning" Of Ceramic Paint Palettes   
    I don't even like to make tea in a cup or mug that isn't white inside, I am only a very occasional and very amateur painter but I also couldn't use anything but a white palette.
     
    It's like how glazes appear different on different clay bodies, if the paint is going onto a white ground it has to start on a white palette.

    Only guessing here, (I've not yet worn out any elements) but as you have less element material than in a larger kiln wouldn't the effect of deteriorating elements tend to show up much quicker?

    1) That would be considered normal/standard - but you do whatever you want,  the Amaco Velvets for example have a pleasant finish when unglazed, and if the clay is correctly formulated and fired to maturity it shouldn't need glaze.
     
    2) All the underglazes I've used can be watered down, often they benefit from it, although you would then need more coats to achieve the advertised colour, they are very much like watercolours in that respect.
     
    3) The clay and glaze need to match:  a ^5 clay needs glazing with a  glaze that's formulated to fit the clay when fired to ^5.  A ^10 glaze won't have melted properly at ^5.  Most underglazes nowadays will fire to ^6 without washing out - the destructions ought to tell you.
     
    4) I use compressed air to blow off the pots if I'm spraying the glazes, it only takes a moment to change the sprayer for a blower, (be wary of breathing the dust), I will have already given them a wipe over with a damp sponge. The pots can be made quite wet before glazing if you have a reason to do it - the main reason would be so that they take up less glaze, or you can wash them and leave them to dry.
     
    No-one here minds what may seem to you like trivial questions - I'm sure I've asked a few myself over the time I've been here.

    Absorbent bats (mine are all plywood)  need to be damp (just damp, not wet),  If I'm going straight on the wheelhead I like it dry. Smack the clay down harder, also when your clay is wedged and ready to go on the wheel,  round off the bottom a little by rolling it around until it's like one of those toddlers toys that wont fall over, this will prevent any air pockets underneath and ensure good contact if you smack it down hard enough.

    ayjay got a reaction from Chilly in Qotw: How, When Or Why Did You Start With Working In Clay?   
    I'm sure I've said before; my wife started pottery classes at our local Adult education Centre, after three years she was still bringing home a multitude of strange misshapen lumps (these were thrown, not hand built)  and I found myself wondering -  "how hard can it be?" 
     
    So I started going as well, it's not hard at all, my wife is just crap at it.
     
    As an aside, pottery is how I came by the name Ayjay.
     
    Everyone in my father's family is known by their second given name - I don't know why, (but I could speculate).   So, I've been known as John for all my life, although first name is Alexander. 
     
    I arrived at the pottery class the very first time and my wife said, "This is John".   The tutor said, "Well who is this Alexander on my list" 
     
    After a few seconds of trying to explain she said, " I can't handle all that, you'll have to be AyJay,  and so far as pottery classes are concerned I've been Ayjay ever since, I doubt that anyone there actually knows my proper name.
     
    Ten or so years on I'm still potting, (my wife can no longer even attempt it  because of her MS).

    A guy where I learnt to throw quite often used to make large stuff like bread crocks and hand washing bowls - he was a very experienced thrower and to me at the time, the amount of clay he was throwing looked almost monumental.
     
    ..........BUT, he had a lot of problems with S cracks in his bottoms, so make sure you compress your bottom well and maybe also take the precaution of firing it on something that will allow some movement.

    ayjay got a reaction from Sheryl Leigh in Drying Cabinet Idea   
    Sometimes i think it would be really neat to have things dry more quickly, but I reckon on the whole I'm happy with my slow drying garagio, no heat and no draughts.
     
    I can throw pots and leave them uncovered for 10 days or more before they're dry enough to trim. It gives me the best chance to catch them at the right time for trimming/attaching handles etc.
     
    I've not tried, but I reckon sometimes I could put them back on the wheel after a week and pull another lift.
     
    If I need to speed them up they go outside if it's breezy and in the airing cupboard if it's not.

    When I hold a piece to my cheek to test for dryness I encounter my beard, I'm guessing that you don't have that problem.
     
    It's just belt and braces for me Chris, I already know it's dry: it costs me 1 kw of electrickery for my usual candling routine, it's nothing - 12 pence, and the kiln is then preheated so my bisgue fire costs proportionately less.
     
    In my 50 years as a Carpenter, nothing has ever collapsed, fallen off the wall, come apart or failed in any other way because of poor fixings etc - my  belt and braces mentality is the reason for that and it works for pots too.

    If you want consistency, then most vessels are made from a certain weight of clay proportionate to their holding capacity when finished.
     
    A 2 pint casserole takes about 2.25lb of clay and will measure 4" high X 6.5" wide
    A 4 pint casserole takes about 4lb of clay and will measure 4.5" high X 8.5" wide.
     
    I got these figures from another website and tested them recently and found them to be pretty accurate. The lids used about 1lb & 2lb respectively.

    I'd make the lid too large and then trim it down.
     
    Roll out clay, put over bowl.
     
    Make a flat cardboard template, cut a hole at the centre which is the finished size of the lid, put over bowl (and clay) and trim lid to size.
