  1. Thanks everyone, I sorted it. Just in case anyone gets the same issue, here's what I did: I popped it apart by stacking various pieces of wood between the head and the base and using leverage. The photo below was taken at this stage; before cleanup. I then used an air compressor to blow any loose stuff out. Then sprayed degreaser into the bearing. Then flushed it out with water. Allowed it to dry in the sun. Packed some proper grease into the bearing. Also cleaned everything rusty with wire wool and WD40. Popped it back together. Now it spins beautifully. I've just given it a good spin and fully expect it to still be spinning at Christmas...
  2. Thanks. I've given it a good old dose of WD40. I'll leave it a while and see if anything happens.
  3. Hi Hulk, Here's a picture of the bottom side. Nothing drops and it all seems very strongly connected Like I could turn a pickup truck on it. It spins okay most of the time at very slow speeds. Any faster and it judders and halts.
  4. Hi, I wonder if anyone can help? This morning I went to the closing down sale of a pottery in London and bought, among other excellent things, a huge heavy (38lb) Podmore banding wheel. It ran like silk and span forever. Drove it home and now it judders and stops straight away. There doesn't seem to be an obvious way into it. There are no screws or access points. Anything I can do or has my shoddy driving destroyed it? Thanks.
  5. Hi everyone. Thanks for all your answers. The kiln is now on a proper tiled surface on a concrete floor. I appreciate that a key reason is in case of issues/problems such as hot things falling from the kiln, but I was curious about how much heat comes out of the bottom in normal use. I wanted a rough idea of the heat work, not a max temperature. So I thought I'd try an egg in a pan first, then work my up through vegetables etc. I've got a K type thermocouple that can record maximums, but it's not as much fun as an egg... This was a glaze firing reaching 1250C (2282F), and as you can see, the egg in a pan is immediately beneath the centre of my Nabertherm Top 45. I was very surprised to find in the morning that the egg hadn't cooked at all, just dried out a bit. Hooray for insulation!
  6. Thanks for the replies. I fired it empty but with the shelves and props in first time and followed the manufacturers instructions. As this was my very first fire ever, I was very careful and followed all the instructions in the massive manual. I put 3 posts in and ensured they were all aligned. It was a slow bisque fire. The controller handles this automatically, but as I was excited I kept going in and looking at the temps. It was all correct and nice and slow. I even managed, with enormous self control, to wait until it was cool before I opened the lid. I couldn't have been more careful, so the hairline crack suggestion makes sense to me.
  7. 3 posts were holding up the shelf. It's on a fire blanket on some thin laminate which is directly on concrete in a shed. It will be going on tiles for the next firing.
  8. Hi, I've just done my first ever proper firing and the top shelf snapped in half. Taking my 2 best pieces with it. The 2 shelves below were fine. I have no idea why and am trying to figure it out. It's a new kiln (Nabertherm Top 45), I followed the gigantically complicated instructions for doing the very first firing of the empty kiln and furniture. That went fine. Then I did this, my very first ever biscuit firing of my first ever home made stuff. Could barely sleep for the excitement of being able to open the kiln. Any idea what would have caused it? Could it be that the stuff was too heavy or too badly distributed? Many thanks, Laurence
