Assembly Instructions

16

The track should be glued to the frame in two stages. If you use CA glue you can simply hold the parts in place while the glue sets. If using wood

glue you will need a scrap of MDF and some rubber bands to hold the track in place while the glue dries. Start by glueing the track to the lower

track support and the side support. Once dry you can glue the track to the upper track support.
