esantoro Report post Posted March 9, 2007 I buy bonded polyester thread whenever i can get a good deal on it. The result is I now have years worth of thread that is drying out, so I;ve decided to set up a lubricant reservoir on my super bull. What kind of lubricant should i get: silicone based or emulsified parafin? One thing nice about the emulsified parafin, which CB told me, is that it can also be used to burnsh edges.
