I used the hand saw, now why I did not use the electric circular Saw? Because I want to and after all, it is my green project alas save the electric! After all, I think I gain some muscles and sweat profusely. No Pain, no gain. Go ahead measure the one wood by line it up to the studs that are "back legs" then saw them into for piece, Glue and nail the two wood to each side of stud. Ignore middle stud. Now you have front legs!
