Instructions
Spread out all the pieces from the Meccano Erector set on the floor. Analyze and identify each part by comparing it with the list of parts included with the set. Typical parts in a Meccano Erector set are, metal strips, wheels, axles, angle girders, pulleys, gears and other mechanical parts. Each part has a code to cross-reference with the parts list.
Look carefully at the model drawings supplied with the set. The drawings describe how the parts connect. Each part is labeled with its code to identify it easily. If more than one piece is required, the label will have the number of parts you need within brackets. For instance the label or call-out "38-(2)" means you need two of the parts coded 38 in your set, which in some sets is a 17-hole girder.
Connect the parts with the screws, washers and nuts included in your set. Match the holes of the two pieces you wish to connect. Place a washer on the outer side of each hole. Introduce the screw through the washers and the hole and screw on the nut until tight. If you want the pieces to be able to swivel, turn the nut counter-clockwise.
