All parts of the Industrial chassis can only be assembled one way.
Most parts are common between SM32 or SM45 variants - the chassis plate and axles are simply wider, however construction method remains the same.
General Assembly
Information about pressing the bushings into the side rails and assembling the wheels/axles can be found in the general Assembly Guide here.
Due to the rapid "grab" time of superglue it is possible to assemble the chassis in one process and allow to fully dry, the below steps are only a guide.
Assembly on a sturdy flat surface is advised to ensure correct geometry of the finished model, at each stage ensure parts are square and level.
