When cutting large moldings with my old 10" Miter Saw, the blade guard will hit the top of my molding before a clean complete cut is made. This is when I wish I had a new 12" sliding Compound Miter Saw, but I don't. So I have to finish the cut with my handsaw. The deep kerf made with Miter Saw makes it fairly easy to complete but it still slows the process. If you run into this same proble, a sharp fine toothed Handsaw is what you need to complete these cuts.
If you don't have time to do it right the first time, when will you have time to do it over?
