HHad to look up cell rot. No, there is no rust on the blade at all to indicate any celluloid rot. Should I increase to two layers of tape at 4k and 8k? If so, is the idea to have a double bevel, or something else? (trying to understand this)
Should I do X strokes at 4k and then on 8k, or should I do a pyramid? If former, how do I know when to advance from 4k to 8k?
Thanks for the guidance!
