Today I worked on the left shoulder again. The plan was to create a plastic shoulder housing that goes on over the tire mount bolt.
Bent a new tire bolt bracket from a 4 inch L-bracket, new workbench vice came in handy.
Started a cardboard template for actual shoulder housing.
Cut out bottom corners of a white plastic bin for material, and riveted them together. The exposed rivets turned out looking cool.
Worked great, now to make the right side shoulder and other tire. At least I won't have to paint the shoulders because white was the intended color.
