Flyangler; that's a new one for me....cork as an eraser so to speak. I am a beleaver that what ever works for each bulder is good for them. We all have our own little tricks on how to do things and that's great. I will have to give that on a try some day, for I would be interested in knowing how much heat is generated. I have always shyed away from using any source of heat against a rod blank due to the damage it could likely cause if overheated.
