Woodturning Random Angle Miter Bowls - Tapered Stave Shortcut

Splayed miter, tapered polygon or stave bowl cut on a simple miter saw.
Don’t beat me up too bad if I’m just the only fool that didn’t know how to do this.
So here is my attempt at sharing what I first thought of as the “Round Angle Miter Cut” but now think of it and call it the “Random Angle Miter cut”… Or for simplicity, the RAM cut. (Yes… did that on purpose… 🙄)

Maybe I’ve just missed it, or maybe the limitation on the size of the wood or the turned piece being made precludes mitering wood this way. No doubt my experience and knowledge are limited.
So this is either a community service or a fools errand.. I’m sure your comments will help sort that out. 😂
Not sure about the proper nomenclature for this type of miter cut, have heard “splayed miter” or “tapered polygon miter” and a “stave bowl” cut.
No matter what it is really called, I haven’t seen anyone do these cuts on a miter saw. In fact, have seen some very complicated math and Tablesaw apparatus to make these cuts. My table saw isn’t very precise and making special brackets to attach to the tablesaw just isn’t me.
Well, this type of cut can be done on a simple miter saw.
Granted, using a miter saw has its limitations. it isn’t for precise work, but for my tools and purposes it works great.
So, without any further fanfare, thought I would share what I have come to call the “Random Angle Miter” cut.
Using an “L” shaped bracket, clamped to the miter saw, this will hold and help guide the wood through the miter at an angle. This first piece is a Douglas Fir board at 2 and a quarter inches wide specifically set it at 20 degrees. The actual miter setting is 30 degrees, so that the bowl will be six sided. You can use any normal setting for making an equilateral polygon shape. For example, could have used 22.5 for 8 sides, 20 for 9, or 18 for 10.
Without changing the bracket, this 2nd plywood board was 3 and a quarter inches wide. With the same bracket set up it had an angle of 13 degrees. Again, here I used 30 degrees for a six sided polygon.
Doing it this way with different widths on a single guide setting, the angle of the bowl sides change as the width of the wood changes. The thinner the width, the larger the angle.
This final Oak board at only 1 and 3 quarters inches and is the thinnest using the same bracket setting, so the angle moved to 24.5 degrees. Still using the actual miter setting at 30 degrees to create a six sided equilateral polygon. Also note, while you can’t see it, the saw surface was marked to measure the lengths of the cuts for all these bowls.
One of the drawbacks is having to figure out how to finalize the bottom of the bowl. Obviously you can sand it down or cut it level, but a simple method is to use resin. A slight sanding to make sure there is good contact with the tenon piece for glueing. Then just fill as needed with resin.
One of the upsides is this provides for a nice scalloped edge. You can see that if you hang around to watch these get finished.
There are a couple other tricks I use with the Random Angle Miter or the RAM cut for short, particularly when making vases. Will share those tricks in future video posts…
This is similar to the process for cutting crown molding. And there is even a tool for the miter saw to cut crown molding. Although I have never personally used one.
Hope this was helpful, if so, please subscribe…
For now, will just finish these 3 bowls and call it a day.
Otherwise, hope you enjoyed and thank you for your time.

I'm going to give it a go in the near future as I have other projects already in the works & I'm retired so I don't play every day. More or less when the mood strikes me. Thank you again .

[@6275WJB]

Well, I'm one of those fools too, I always thought there had to be away, they put a man on the Moon so someone must have found a way to do this technique. Great video. 👌👌👌👌👍👍

[@ramwoods]

Thank you. Still haven’t seen this anywhere else, but agree, can’t imagine it is anything new, just not widely used. Appreciate your review and comments!

[@teckle.turnings]

Awesome well done! 😃

[@ramwoods]

Thank you so much…

[@TazioCostantini]

👍Great job! bye😊

[@ramwoods]

Thank you very much.

[@DougMilleratWoodSpunRound]

This is a great look. I’ll have to watch again and do some experimenting. Well done.

[@ramwoods]

Thank you. Really wasn’t sure how the video would be received so your kind words are most appreciated.
