A Recurring Problem and a Question
Posted 13 July 2012 - 07:58 PM
Also, I've played with the throwing stick tool, and have a 50/50 record with it. Sometimes it works awesome, but other times, all it does for me is scrape out tuns of clay on the inside, and making uneven lines inside. I'm assuming the stick should be wet? How fast should I use it on the inside? Any other tips?

When pulling up the wall when at top use your 3 fingers to level off the top-Robin hopper has the tiger move mine is three fingers that smash the lip together as one. Do not let lumps appear so fix them before they appear.

I will bet it's not at the end that you have a problem, but at the beginning. The opening has to be truely in the center of a truely centered ball, or there is more clay on one side of the ball than the other. No amount of leveling, cutting off will fix that, since it keeps coming from the ball of clay every pull.
More time at the wheel will address that. Has anyone centered a ball well and then let you FEEL it turning on the wheel? If it is well centered, it will seem to be still, while it is spinning. If you can feel it turning, it's not exact.
I am assuming you mean a high spot, feels sort of like a traffic bump? not a chunck of clay burried in the rim?

When opening , hold your hands steady for several rotations when you reach the low point inside the lump before pulling up.
When pulling up slowly, hold steady and have the finger marks more horizontal than vertical. Uneveness comes out at the top once you start pulling up and forming.
Use a rib to compress the walls into even thickness if you have uneven walls and trim the top with a pin tool. Repeat as you need to.

This is good advice. If you can brace your arms as much as possible, and your fingers/hands against each other, you can get a smoother lift. You can think of the wheel as being an electric screwdriver, and the throw-rings as being the fluting on a screw. If those rings are nice and even, and close together, the walls of your pot will be more even. I may be making a video of me making mugs this afternoon. If I do, look for me posting it. If I can remember I'll try to address your problem at least as I'm perceiving it.
