    what about a mitter box?

    A question in the set builders test is: “How do you cut crown molding?” Answer: upside down and backwards. One can always flip the molding and set the saw to the opposite 45 degree angle, then cut as deeply as possible. Having done that, lay the molding flat on the saw table and try and match the bevel and miter of the partial cut. Mess up a few boards doing that and you’re in.

    Holly cow brother, I would rather mess up few boards rather than doing what your doing.

    I would have just bought a bigger saw

    Thank you very much Sir, you’re the only one who was able to explained it scientifically. I hope you will teach us more for acute, obtuse and reflex angles that Crown molders might encounter in the future. I am familiar with the tables but still don’t know the math involved, but thanks to you – now I know a lot more about Crown moldings scientifically. More power to you and God bless!

    Excellent. I wish my maths teacher was as clear as you.

    what if your wall isn’t square?

  8. dmvella3 says:

    did you do all this math because the saw would not accommodate the height of the wood? it seems like setting your saw to 45 degrees (if it would fit) and mitreing a normal right angle corner fit would be way quicker

    @danny223009
    Hopefully not while you were runnning the chop saw.

    If anyone using the same model of calculator that Donny is using and does not get the same answer, I have discovered on my calculator which might be a newer version of the same model.

    On my calculator you have to press the DRG (degree button) after you input the 45 which is 1/2 of the corner angle in degrees

    Well, you’re right about the .625. My mistake. But somehow, the mitire worked out close enough.
    Regarding the calculations, I redid my math on the same old Sharp calculator I used in the video, and the figures came out the same.

  13. BrushCountryJamboree says:

    Also 5/8″ does not equal .645 it is .625

  14. BrushCountryJamboree says:

    i bought the same calculator your using and i am getting the following answers
    .815916148 for the miter &
    .692128898 for the bevel.

    so whats the deal with this

    you need to zoom out enough for everyone to see exactly the keys you are pressing & when your pressing them
