NONESafety Requirements
NONEProcedure
Use light pressure to prevent any risk of overheating material.
Any polish marks must be in a radial direction from the vane ID to OD.
Surface finish of the repair area must be the same as the adjacent area.

CAUTION
WHEELS, STONES AND ABRASIVE PAPERS USED TO DRESS, MAKE SMOOTH, OR POLISH A TITANIUM COMPONENT MUST BE OF THE SILICON CARBIDE TYPE. ALUMINUM OXIDE TYPES MUST NOT BE USED.IF MECHANICAL CUTTERS ARE USED, ONLY SMALL CUTS MUST BE MADE TO PREVENT TOO MUCH HEAT.Scallop, make smooth and/or hand polish to remove nicks, scratches and/or damage.
Remove the minimum amount of material necessary to give correct radius.
Refer to the SPM TASK 70-35-03-300-501.
Hand polish the vane leading and/or trailing edge radius and the vane profile to make a smooth shape.
SUBTASK 72-32-83-350-051 Remove the Damage from the LPC Stage 1.5 Vane Assembly
Follow inspection procedure as given in TASK 72-32-83-200-000 (INSPECTION-000).
Do a visual and dimensional examine on the vane.
SUBTASK 72-32-83-220-051 Examine the LPC Stage 1.5 Vane Assembly
Refer to the SPM TASK 70-23-05-230-501.
Make sure there are no cracks in the repaired area.
Fluorescent penetrant examine the repaired area.
