2 different types i know of. 31 and 45 angles. get a few pieces and practice. after a while u`ll get good. a compound miter with the approiate cut abilities would be ultimate. a regular miter saw will work as well depending on how u hold the material. a manual one will work as well. even a skill saw can do it if the individual is skilled enough. always have been told the fat side goes dwn but don`t know why u can`t do it u`re own way.
