2. Check the balance of the blade by putting it on a

blade balancer (Figure 67). If the blade stays in a

horizontal position, the blade is balanced and can be

used. If the blade is not balanced, file some metal off

the end of the sail area only (Figure 68). Repeat this

procedure until the blade is balanced.
