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 surfaces 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.Back off the dowel pin jack nuts, and 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.

6.Mount a dial indicator with a magnetic base to the top of the saddle to indicate alignment.

7.First test the peak of the two prisms of the gap insert that the saddle rides on, then test the flanks of the prisms.

8.Tighten the gap bed cap screws in an alternating manner and tap the side of the gap insert into alignment.

9.Inspect the gap alignment 24 hours later to make sure the gap is still aligned. If necessary, loosen the gap bed cap screws and repeat Steps 7–8until the insert is properly aligned.
