Step 4: Heel welding

Picture of heel welding
The original heel for this shoe had a wide flange at the heel which helped support the width and weight of the heel and foot. This new design calls for a slender, uniform heel spike and will require a platform to support the wearer's weight in lieu of a wide flange like the original. 

A small heel platform was made from scrap 1/8" sheet steel. I used an angle grinder to cut out rough rectangles, then rounded the corners until I had a platform that fit inside the insole. The platform was then welded to the steel shank.

The 1/4" stainless steel bolts were then lined up and tacked in place to ensure position was correct. While the bold is tack welded on is a good time to make any minor adjustments to the angle of the bolt. It helped to put the insole and shank back in the shoe with the tack weld to ensure the heels are perpendicular to the ground. When alignment is ensured, weld the bolts in place for both shoes.

Cut heel spike to length:
After welding the insole and shank was put back into the shoe with the dinosaur placed along side. The heel spike was then cut to be about 1/4" longer than the height of where the dinosaur back will meet the shoe.
