After welding it's time to decide our dinosaur placement. I lined up my dinosaur under the heel of my shoe with the underside of the heel resting on the back hump. Looking down from the top of the shoe into the opening, I marked on the dinosaur where the sole and dinosaur met. Then, using a 1/4" bit, drilled a 1/4" opening through the dinosaur.
Getting the angle and exit point correct on the dinosaur was difficult. I picked up an extra dinosaur that I made several openings through until I got the angle I was looking for, then transferred those locations onto the other dinosaurs.
