Jesse, here is my truck building jig that works for Rio Grande HOn3 trucks. The truck is built upside down with the bolster sitting along the plastic stock. I glue one sideframe to the bolster first using medium ACC. Place the glued assembly (bolster and one sideframe) in the jig with the second sideframe. You can then pivot the sideframes to work the wheelsets in before gluing the second sideframe. -- Brian Kopp Jacksonville, FL
