1. Prepare the oar by jigging, so that the blade is vertical and the bottom surface is facing up.
2. Apply about 7 inches of masking tape to the top surface of the oar shaft.This will be used as a guide for your marking and drilling.
3. Using a level to help you, make a line lengthwise.This line will mark the absolute top of the cylinder.
4. Now that the axis is marked, measure in 12.7 cm (5”) and 14.75 cm (5.8”) from the end of the oar. This will give you two marks 2.05 cm (0.8”) apart.These marks should line up with the holes on the clamping plate.
5. Using the smallest available drill bit (5/32” works well) drill a pilot hole at the marks. Using a small bit for the pilot hole helps prevent walking of the drill bit during drilling. Next, bore the hole slightly larger with a sharp bit and light pressure. Finally, use a 1/4” bit to bore the hole to size. Again, be careful to use a sharp bit and light pressure to prevent damage of the carbonfiber.
6. If you are using Concept2 oars, you can now install the included backing plate and hardware into the new holes before adjusting the adapter shims (shown below).
7. For Concept2 oars, glue the included shim strips to the C2 adapter shims. Attach 2 white shims to one adaptor and 2 yellow shims to the other adaptor.
8. Fit the adaptor shims to the BalancePoint handle, and insert the whole assembly into the oarshaft. Make sure to properly align the slot to the clamping screws.
9. Finally, set the correct length of the oar and tighten the clamping screws. Be careful not to over-tighten the screws, as the oar shaft can be damaged.
