1st, thanks everyone for the answers. I never knew how the mats were cut until the class and it just seemed like an easy cheat to get matching cuts.
Todd, I will try and explain. Lets say you are going to cut a 16x20 piece of mat with a 10" x 14" opening (3" border) and a 2nd mat with a 1/4 inch reveal.
set the depth to 3" on the cutter and cut the mat as you normally would (save the part you cut out for use later, try and mark it so you know what way it would go back into the opening you just cut). On the second mat cut it to 15" x 19", put ATG tape around the back of the 1st mat in about the center of the border and then center the second mat on the 1st mat and stick it to the 1st mat (color side down, against the tape).
Now you need to stick the piece you cut out back into the opening using ATG tape-taped to the 2nd mat. You do this so you have material under the cutting blade while you cut the 2nd mat. So now you have the 1st mat cut, the second mat taped to the 1st mat and the piece you cut out of the 1st mat taped back into place.
Now you set your depth guide to 3 1/4" and make your marks and cut just like you did with the 1st mat. With the 2nd mat smaller than the 1st mat the 1st mat is lining up with the guide, this allows the cuts on the second mat to be cut using the same edge as the 1st mat and therefore the cuts on the 2nd mat should be square with the 1st mat.
I hope this helps, not the best at explaining things.

Thanks Framah.....
Your post is helpful for those of us who don't do this day-in and day-out (like I believe you do).
As far as the cuts go, I'm trying to figure out (I'll reread the original post), how I could align my edges with the outer mat using the Logan mat cutter. I'll double check the videos that Logan supplied....maybe they show it in there and I just didn't remember.
Thanks again for the tips sir! It actually makes it easier to use the Filmoplast P-90 tape for both.....one less item on the table.. :-)
Cheers....
