A device for installing blades into a slotted disk comprising:
- a rotary table for supporting and providing rotary motion to the disk;
- a horizontal adjustable arm;
- a vertical pivot bar perpendicularly attached to a first end of said horizontal adjustable arm;
- a roller assembly attached to a second end of said horizontal adjustable arm, said roller assembly engaging the blade roots;
- a saddle attached to said vertical pivot bar, said saddle positioned beneath the blade tips;
- and
- wherein said roller assembly exerts downward force on the roots and the saddle exerts upward force on the tips as the table rotates, thereby seating the blades in the slots.
