Illustration 1. Components of FT1783 Drill Fixture.To use the FT1783 Drill Fixture, put the impeller in position on the plate. A vane of the impeller must be against the locator. See Illustration 2. Use the T-bar to hold the impeller in position. The drill fixture and impeller can then be put in position in a vise as shown in Illustration 3. Use a level to make sure the plate is perpendicular to the drill. Use the two holes in the fixture as guides, when 6.35 mm (.250") Ø holes are drilled.
