Oars are easy most - the longest part is letting the glue cure. I painted the wrapping to help protect it from wear, waterproof it, and dress up the oars a little bit.

Remember: I am a wood butchering hack. If you want to see how a real boat designer makes oars, you can get free plans from our friends in Australia: Michael Storer, designer, owner, and all around good guy at Storer Boat Plans has free plans for oars here: http://members.ozemail.com.au/~storerm/Paddles/FreePaddle.html
