Jerry: That mullering is a blast isn't it? I did the 32 lpi trick also then used a die sinkers riffler with a tapered point that was bent upward at about 45degrees. I ground it back till the tip was slightly smaller than the finished mullering width and sloped the grind backward to a sharp chisel point. I can use it as a file,chisel, and scraper in tight corners. However I think I will wait a while before I do it again. Lee.
