My rack holds 3 pairs of boots.
Step 1: Building the Sides
I welded the sides first using 3 shoes for each side.
Step 2: Adding Sides Together
Added rebar so the bottom of the boot could sit on. It also connects the sides together.
Step 3: Welded Top Shoes Together
Welded 6 shoes in a row. So the rack can hold 3 pairs of boots. Then welded the row on top of the sides. Only thing left to do is prime and paint.
