dado gadget

I am trying to use the dado gadget using a 3/8" bit to cut a 5/8" dado. Is this possible?
thanks for your help

No. I designed the dado gadget to help people who were working with drawings that had dados laid out as rectangles but wanted to cut the dado with a bit the same width as the dado. What it does is to create a centre line toolpath along the longest dimension of the rectangle so the dado will always be the width of the actual tool used.
