Thanks for the suggestion, switching to plywood now…I was told that MDF absorbs moisture and let base dry quicker, maybe not meant to be wrapped.

My throwing bat is MDF so just left the pot on there and thought this way it wouldn’t be distorted and I can lift it when it’s firmer. But yeah agree it would be better to just wrap in plastic.

Hi, I recently noticed that when I wrap pots in plastics on MDF board, it often becomes mouldy around the base of the pots when there is moisture. Not sure if anyone has similar issues and is it better to use wooden boards? Many thanks!

Hi Jeff, thanks for your suggestion. I think this might well be the case. I use a two part mould for the plate where the main part is solid cast with an open back to pour the slip out. It often creates void and it’s not easy to have a complete fill. Maybe I need to redesign the mould…

yes that's my normal firing schedule. There were other pieces made from the same casting slip (from scarva) and they were fine. That's why I was wondering whether the position in the kiln also contributed to the overheating of this particular plate. Maybe I can drop the soak next time.

I didn’t put cone in…it was ramping at 100 degrees per hour until 1250 with a 30min soak.

Ah it is probably bloating. I haven’t broken it because of the painting on the plate and I was wondering whether I can keep it as decorative piece…? The bloating is quite symmetrical so I guess there must be void in between.

Hi, the clay can be fired up to 1260 and I fired to 1250. But it was quite close to the kiln elements.

Hi, has anyone experienced rippled / distorted stoneware plate after glaze firing? The plate was thinly cast using stoneware casting slip. Bisque looked fine. I placed it quite close to the kiln wall which might have caused some stress…the plate didn’t break and I’m wondering whether it will eventually break at some point or is this type of rippling kind of permanently settled. The distortion on the upper and bottom side is somehow symmetric. thanks very much.

Thanks Hulk and Bill. Yes the other side has a square metal plate which holds the bolts in place. The spring is also attached to this part. And the belt also fell off...I put all of them back on now! hopefully this won't cause any issue in using the wheel

Thanks Bill. I will remove the back cover and check the belt. I took the four bolts out underneath the splash pan which was a mistake…now trying to figure out how to re-tighten them….if you have any ideas please let me know. Thanks very much!

Thanks everyone! Does anyone know how to take the wheel head off? The supplier has suggested taking the wheel head off to add a bit more grease to the metal disc but I can't find any video online showing how to grease the disc inside the wheel..... Many thanks!

Hi, I have recently purchased a new shimpo rk55. It makes a rhythmic noise when it spins fast. Has anyone encountered similar issue? Many thanks!! Can’t seem to inset video - here’s the link
