Oar Project

For the 2013 National Boat Building Challenge, which Clare enrolled us as a team as a Father’s Day gift to me, new this year, the Belfast committee decided to add a “Best Oar” competition.  Since this was the ONLY opportunity in the competition to do any ‘real’ woodworking, I decided that this would be a fun and challenging wood working project in its own right.

Originally I considered making the oars out of Ash, but, on researching oars, I realized Ash is usually reserved for Paddles and very long racing oars (single person per oar).  Typically, Spruce is used for the type of oar appropriate for this kind of boat.  Unfortunately, by the time I learned this, I was not able to find any decent clear spruce and, also in my research, I had learned that laminated pine is often used and we have an excellent source of clear pine here in Maine.  I was able to find some good ideas and designs from both the web and a few boat building books.

The result?  WE WON!!!!  These oars were deemed the “Best Oars” in the competition.  I was pleased with the result regardless, but the award, makes this project especially memorable.

Here is the final result:

I enjoyed building these oars as it gave me a chance to try techniques and tools I haven’t used before (or only briefly).  Below is the complete sequence, from start to finish of the oar project. Enjoy!

A couple of nice clear pine planks to start with...
[img src=http://tomstudwell.com/wordpress/wp-content/flagallery/oar-project/thumbs/thumbs_img_4574.jpg]780Marked up with basic oar pattern and layout.
Note that the outer layers are just for the shaft (or 'looms') of the oar.

[img src=http://tomstudwell.com/wordpress/wp-content/flagallery/oar-project/thumbs/thumbs_img_4579.jpg]640All the pieces cut out.
These are really ROUGH cut, using a hand held jig saw to cut them (there wasn't enough space to cut them on my small bandsaw I have in Maine).
[img src=http://tomstudwell.com/wordpress/wp-content/flagallery/oar-project/thumbs/thumbs_img_4580.jpg]600The inside sections were then shaved to the proper profile.
I used hand planes and spokeshaves for this step. It was very satisfying work.
[img src=http://tomstudwell.com/wordpress/wp-content/flagallery/oar-project/thumbs/thumbs_img_4587.jpg]550Set up to cut the slot for the Walnut spline in the ends of the blades.
I did this before gluing on the outer layers so it was easier to clamp to the workbench.

I did one oar at a time since it took so many clamps and space on the bench. Clamp time only needed to be 30 minutes or so.

The outer layers were first cut flush with a router bit on a router table and then the face of the outer layer was rough cut on the bandsaw and, finally, I used hand planes to trim to the correct taper. Note the markup of the taper lines to cut into an octagon shape.

The tool is twisted while the posts ride on the perpendicular tapered faces. The pencils are positioned such that they mark the intersection of a face 45 degrees from the square faces. Very clever device used often in boat building...

I added extra spline to easily accommodate my shaping of the blade.
[img src=http://tomstudwell.com/wordpress/wp-content/flagallery/oar-project/thumbs/thumbs_img_4626.jpg]390To start cutting the octagon faces, I rough cut the top corners with a round rasp.
This gives me a reference point and a place to begin digging in with my drawknife.
[img src=http://tomstudwell.com/wordpress/wp-content/flagallery/oar-project/thumbs/thumbs_img_4628.jpg]380Octagonal faces all cut into the shaft.
[img src=http://tomstudwell.com/wordpress/wp-content/flagallery/oar-project/thumbs/thumbs_img_4633.jpg]370The faces were then rounded over with LOTS of planing and spokeshave work.
[img src=http://tomstudwell.com/wordpress/wp-content/flagallery/oar-project/thumbs/thumbs_img_4635.jpg]370The joint at the blade was left with only the square taper at this point.
[img src=http://tomstudwell.com/wordpress/wp-content/flagallery/oar-project/thumbs/thumbs_img_4637.jpg]350Beginning to shape the blade.
This was mostly done with a hand plane and straight spokeshave at this point.
[img src=http://tomstudwell.com/wordpress/wp-content/flagallery/oar-project/thumbs/thumbs_img_4639.jpg]360Shaped to the end of the blade...

[img src=http://tomstudwell.com/wordpress/wp-content/flagallery/oar-project/thumbs/thumbs_img_4643.jpg]360Basic shape is complete but the round sections are still roughly faceted.

[img src=http://tomstudwell.com/wordpress/wp-content/flagallery/oar-project/thumbs/thumbs_img_4649.jpg]320Made a ton of this stuff!
[img src=http://tomstudwell.com/wordpress/wp-content/flagallery/oar-project/thumbs/thumbs_img_20130815_163012_818.jpg]300Final Oars on the varnishing rack!
[img src=http://tomstudwell.com/wordpress/wp-content/flagallery/oar-project/thumbs/thumbs_img_4652.jpg]280Finished view...
[img src=http://tomstudwell.com/wordpress/wp-content/flagallery/oar-project/thumbs/thumbs_img_4663.jpg]310The rope color choice was Clare's recommendation to match her beautifully decorated transom!
The rope is used to protect the wood from wearing in the oar locks. The thicker section keeps the oar from slipping too far into the oar lock.
[img src=http://tomstudwell.com/wordpress/wp-content/flagallery/oar-project/thumbs/thumbs_img_4671.jpg]300The thick, square section, provides strength and a counter weight for the oars.
The balance point is just below the oar lock so that there is very little of the oar's weight to lift as you row.
[img src=http://tomstudwell.com/wordpress/wp-content/flagallery/oar-project/thumbs/thumbs_img_4674.jpg]330The splines came out reasonably well.
I probably could have spent a bit more time on them.
