10. Extend the two mounting holes in the lower oar lock socket from 4 mm to 8 mm in dia. This so we can bolt the heavy washers to the socket as counterweight for the cam.

11. Mount the lower oarlock socket the same way as the upper one, using 2 screws (K), 2 nuts (M) and 4 washers (O). Again, don't tighten the screws too much, as this will only deform the aluminum pipe. The nylon inlays in the nuts will make sure they stay on anyway.


12. Mount the heavy washers to the oarlock socket using the 2 longer screws (I) and 2 nuts (N). Tip: Once you've found out how many washers you need, you may want to shorten the screws so they won't stick out too much.
