It’s easy, need to use a form of GENTLE heat to soften up the old epoxy around the guides and carefully scrape off the old epoxy. You can usually unwind the thread and take off the whole guide at once. It’s very important to take it slow and not cut into the blank or use too much heat which will melt the blank.
