i have the materials i need but i don't know how to put them together.
what kind do you have? Most I've dealt with have two end frames, two cross braces and the scaffold planks. Hold one end frame up and put the cross bracing on the top and bottom pins on each side of the scaffold end. Then hold up the other scaffold end frame and put the cross braces on the upper and lower pins on each side of the end . (its easier to do with two people). After the two frame ends are up with the cross bracing attached, place the planks on the top rail. If your going up with another section, put the connector pins in the end frames and build it just like the first one.
