remember On piece of trim has to be flipped or cut upside down, or you have to change the saw to the same angle in the other direction

Ruth P says:

I love this for that kind angles but I just tried to do it the opposite angle and had fits with it. It is on a piece of furniture. I finally got it but took a lot of different cuts. You made this way simple and would love to see you do it the other way too! Thank you for your help, love watching you work.

Sampath Gunawardena says:

Randy Hartmann says:

This is really cool for outside angles!! Is there a similar trick for inside angles?

Travis Wilson says:

Oh, I thought this was about bisecting angels. False advertising! Well, now that I’m here, how do you keep your saw so blood-free?
