Hello,

Past weekend I was making crosscuts on some rather large panels (17"+). I used the 5 cut method to check the accuracy of my SMT/Miter.

(Disclosure - I have high OCD)

My calculation leads me to believe my miter is 89.91 degrees as opposed to 90 degrees.

Here is how I arrived at that -

On the 5th cut the piece which was 17.3125" long, was 0.648" on front and 0.543" on rear

0.648" - 0.543 = 0.105"

Divide this by 4 since the error is compounding => 0.02625 per cut over 17.3125".

Therefore my angle deviation is ARCTAN (0.02625/17.3125) = 0.0869 degrees

Since my front portion is wider than rear portion I am 89.9131/90.0869 instead of a perfect 90/90.

So My question is - should I try to improve this or is it futile to get any better than this. (I will have to deal with my OCD )

Someone please check and hope you don't find it is even worse than I think

TIA,

Nicer
