30. Using a 3mm hex wrench, tighten the		35. Loosen the four mounting cap screws and
cam set screws and the clevis jam nut (see		rotate the taper attachment left or right to
Figure 16) when finished.		correct the alignment (see Figure 21).

31. Using 8mm and 6mm hex wrenches, tighten the deadman clamp and the arm clamp cap screws, as shown in Figure 18.

32. Move the carriage so the taper attachment stops completely at the forward-most position, as shown Figure 20.

Figure 20.Taper attachment alignment.

33. Setup a knob indicator as shown in Figure 20, so the knob indicator point is against the top of the dovetailed table.

34.Move the carriage to the other end of the way, read the knob indicator, and note the amount of total misalignment in parallelism between the path of the carriage and the path of the taper attachment.

—If the knob indicator readings show a tilt of 0.025" or less between the two extreme positions of the taper attachment, then the alignment is acceptable. Go to go to Step 37.

—If the parallelism is greater than 0.025", proceed to Step 35.

36. Retighten the taper attachment cap screws, and double check your parallelism.

37. Using the existing pilot holes in the taper attachment housing as guides (see Figure 22), drill out both holes with a 19⁄64" drill bit, and ream both holes with an industrial size #6 spiral pin reamer deep enough so the tapered pins fit flush. If you need to remove the tapered pins for any reason, the internal pin threads are a metric M6-1.
