Use these dimensions to make the bottom reinforcement plate (30) .Note: The reinforcement plate (29) must have a hole with a diameter of 60 mm (2.36 inch). The hole allows access to the grease fitting (26). Refer to Illustration 14. The reinforcement plate for the left side of the stick does not require a hole with a diameter of 60 mm (2.36 inch).
Acquire the correct carbon steel plating in order to fabricate the reinforcement plates. Use any of the following types of carbon steel: BS 4360 grade 40B, ASTM A36, ASTM572 grade 42 or 50, ASTM A108 grades 1008 through 1025, DIN 17100 grade USt 37-2, AFNOR A35-501Q grade E24-2, and JIS G4051 grade S20C.
