If you are using a fat leg, like our 5 inch wide Husky, you need to put the skirt closer to the outside. We recommend about an inch and a half, as pictured. Also, a wider chamfer is needed.
You will need to make the wood bracket longer than if you had a more normal sized leg.
This is the end of a skirt. On the left is a tenon.  There are two counter-sunk screw-holes, for greater stability.
