As an internet post, it was one of the least scary cuts I've seen...
Yes, most often that would be the preferred method! If I were making 2 or more of those cuts and needed a flush top, I'd make a 4 sided, hollow box that slides over the 4 X 4 posts and supports the shoe of the saw on all 4 sides as you work it around. It would fit any 4 X 4 post from that project and any others. Some 1" X 6" - 3/4" scrap, some brad nails and you're done:Is this more or less safe than what I've always seen my dad do which is to just use a circular saw and make a pass on multiple sides?
Even before laser levels, they were cut after being set using a chalk line to set the levelIn these days of laser levels, leave 'em long and cut 'em later.
I've also hung the joists level and cut them flush with a chain saw.
The post in the video looked about 4 ft above grade, maybe for a hand rail? or stairs?
It doesn't matter, just there's no context for the application of the miter saw in the video.
If you ever need to "free cut" with a table saw use this tip. Install the splitter plate if you don't have one already.I thought it worked fine. I would probably have clamped it better if, now that i have seen the arrangement, i ever use it. I expect we have all seen tools used in less than conventional ways. Some things we have a tolerance for, others, not so much. I watched a guy free cut with a table saw once and I have seen it on YouTube as well. An action I am sure I would never do. But, if they are comfortable doing it, who am I to judge? Truth is, nothing about that had me cringing.
