I also use figure bite in the lathe, but when I feel a sense of incongruity in cutting, I can easily re-polish easily. Once, the handle part and the grinding stone part peeled off, but it seems to be because the plastic used slightly. Here is non-existence. I got a story with instantaneous adhesive. Cut off the PET bottle and store it in light oil so it can be used immediately. However, because dust is worrisome, I want an oil-resistant transparent plastic container with a lid of about 60 mm.
