I am a novice framer. I have read extensive posts on the internet, and the consensus seems to be that it is virtually impossible to get a perfect 45 degree miter with anything less than a top end saw or a morso chopper or equivalent. A cheaper alternative would appear to be a miter trimmer/and/or a sander specifically designed to sand at 45 degree angles. Can anyone give me any feedback on these tools. Are they worth the expenditure? Do they correct the cheaper alternative. At the present time I have a modestly priced Ryobi miter saw that I purchased a from "Framing for4Yourself with a 80 teeth blade. The cuts are surprisingly smooth, but, as of yet, my frames are relatively narrow. I understand that wider frames produce more problems.
