Yep, the overall dimensions include your edges, so you need to make your base template 2mm smaller all the way around.

Yes, undersize your base template accordingly. Also, you will have a step in this shape if you are doing “3/4 wrap”. That is, if you are not fully wrapping the edge around the base.

I always leave the template at full size and use the router to take the 2mm for the edges away from the base.

I’ve never tried that - very interesting. Just an undersized bearing with a flush cut bit? Do you do 3/4 wrap by carefully locating the ends of your cut?

Yes, exactly as you describe

Most of my snowboards end up being 4mm wider than originally intended because I keep forgetting this when I have my templates cut....
. Luckily for snowboards that is not much of an issue.

Your template should be sized with out the edges. So subtract about 4 mm from your desired finally dimensions.
