I don’t mind making mistakes because that’s where you learn, but man is it frustrating when the changes don’t help! (Especially when you have people waiting on you.) I haven’t notice any kind of change in sound with the wheel which is why I assumed it was my doing even though my throwing was fine till it suddenly wasn’t. I just ordered the new belts so hopefully they’re in soon and I can give you an update. Thank you for responding and the reassurance! There is always room for improvement, indeed!
