Gap Installation

1.Use mineral spirits and a clean lint-free rag to clean the mating surfaces of the gap, bed, and ways. If necessary, stone the mating sur- faces to remove scratches, dings, or burrs.

2.Wipe a thin layer of light machine oil on the mating surfaces.

3.place the gap insert into the gap and use a dead-blow hammer to align the insert with the lathe bed.

4.lightly tap the dowel pins back into their respective holes until they are seated. This process will further help align the gap insert and bed mating surfaces.

5.install all fasteners and lightly snug them in place.
