3D Boat Shape

The end of the story from the last post is shown below, as I am tuning up the final angle where the sheer log meets the bow. It may look simple enough, but hanging on to a screaming body grinder at a precise angle with 36 grit paper is no casual task. I could have used a saw and a file, but, if the edge is visible and there is room to move, it is the fastest and most direct path toward completion.

I have long wondered what built by hand means, but if it is anything beyond shaping something strictly with your fingers, then this concentrated, practiced effort has to qualify also. Taming the body grinder is on par with training our Boxer dog Buck.

He never was fond of the leash, and pulled continually toward the next interesting scent or dead treasure. We always had to be prepared for the surprising and potentially injurious jerk, should any rabbit or any other animal jump to flee.

The grinder can be a lot like that dog. It pulls, it whines, it catches and jerks, all the time requiring it be handled with gentle pressure. But if it is mastered, it pulls as hard and fast as an Iditarod sled dog.

Those long sheer logs or moldings are now faired, and assembled into the framework of the boat. Now, it allows the imagination to go down the road a ways, as the 3D shape is coming into view.

Tough Transom

The next up assignment is making sure the transom is strong enough to hold a 500 pound outboard motor under working conditions. That also means all of the railroad crossings and the normal Indiana roads. The transom itself (taped off) was made of 5 parts of 1/2″ marine plywood, laminated with epoxy.

Next, an inside corner brace was added, made of four laminations of marine plywood. The outer trim edge was dowelled and epoxied to the core.

Then I epoxied the triangle to the boat keel and the transom. On the surface, I added fiberglass fabric, embedded in more epoxy, which connected it all together with much more strength. Notice the gray corners which are epoxy fillets, for even more durability.

Some times I try to imagine what kind of stress or blow could actually do harm the the part I am working on. I would love to see some strength testing on this piece of work, but rather than waste the time and wood, I go on with confidence. The last boat is seven years and still floating . . .
