Assembly (Crane)

• The wheels are each secured to the base with an M2 cap head screw, with a washer in-between the wheel and the base. Don't over tighten the wheels, they should spin freely and even have a bit of wiggle. 
• The core slides into the cab with the smoke stack coming out of the top. A drop or two of glue will hold it in place.
• The boom is secured to the cab with an M3 screw.
• Press fit the 6mm round magnet into the hook. Again, I would recommend a bit of glue.
• Use the section of filament as a pin to attach the hook. The holes in the boom should be snug, if they are too tight to pass a piece of filament they can be reamed with a small drill bit.
• Secure the cab assembly to the platform with the remaining M3 screw. It should be able to spin freely.
• Attach the platform to the base with glue.
• The ring magnets go on the nubs on either end, and the tacks go in the holes to secure them in place.

Assembly (jib carrier)

• The wheels are each secured to the base with an M2 cap head screw, with a washer in-between the wheel and the base. Don't over tighten the wheels, they should spin freely and even have a bit of wiggle. 
• The body sits in the slot in the base,  A drop or two of CA glue holds them together. 
• The ring magnets go on the nubs on either end, and the tacks go in the holes to secure them in place.
• The 5mm cap head screw screws into the central hole. It should tap its own threads. This provides a place for the hook/boom to rest during transit.
