Sled for 45 degree angle

I just rebuilt my crosscut sled using the 5 cut method to dial the fence in to make it extremely accurate. I am planning to make a sled to cut perfect 45 degree miters. do any of u know of a similar technique to make sure the miter is perfectly accurate?????

The so called "5 cut method" is something that has shown up on woodworking info sources. I don't know why folks think this is some type of accurate way to test their sleds and other cutting tools. The slightest mistake will be multiplied 5 times and you'll never know if all or one of the cuts was off. All that is ever needed is an accurate square and your eyes.

make 2 miter cuts, dry fit the pieces together and see if the result is a square/90 degree angle.
If it's greater than 90 degrees, your miters are over 45 degrees ... if less then they are under 45 degrees. Compensate by making 1/2 degree changes, since that will make a 1 degree resulting change.

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

Make 2 cuts...flip one piece over and lay both on known flat surface. cuts should meet perfectly if the cuts are exactly 45.

See the link below. It is a simple way to make your sled more accurate than can be seen by the naked eye.

"More accurate than can be seen with the naked eye"? Interesting. Gotta get me an electron microscope.
