Check the Pitch of the Blade at the catch and finish positions.
Bend the Pin at No.2 point using a Bending Tool (see below right) to get the amount of pitch required. After the pitch has been set you need to make sure there is enough free space to allow the oar to release easily out of the rowlock.
Bend the Pin at No 3 point to allow the oar to spin freely.
If the oar can come out of the rowlock when located as per drawing, then the gap was set correctly. This will enable oar to pop out at times of undue pressure and help prevent damage to oar and injury to crew.
