Star 45 Construction Planking with edge glueing

[Star45] Update on planking bottom with edge glueing.

John Fisher is ready { 4/19/2007 } to glass his latest boat and is sharing how he planked it. His dad built a ply sided, cedar planked star using titebond II and it came out pretty light and stiff. With this information I started to build another hull using the same materials. He felt that edge gluing the planks added a lot of the strength to his boat. John didn't want to glue in extra wood to hold the pins to keep the planks in place for the glue to dry, so I combined two methods of planking. John liked the quickness of planking with CA and kicker, but it lacked stiffness when sanding the bottom before glassing. So he decided to edge glue the planks and then tack them in place to the frames with CA.

In this photo you can see where John put drops of CA on the planks. The wood is slightly darker.

It worked well. John has an edge glued bottom and he was able to plank it in one evening. To do this John first spray the frames with kicker, then apply titebond III to the edge of the planks. He then would hold the plank in place, tight against the previous plank, and apply a drop of CA to each frame to hold it in place. It did not matter where John started, bow, stern, or middle, but do make sure the CA has set up before moving to the next frame. Once the whole plank was in place he came back and wiped off the extra titebond. To fair the bottom to the sides he used a $10, 6" plane from home depot set at .010" depth of cut. It quickly removed the cedar and a little sanding finished the job.

John had one plank that was too thin that he had to remove, it was harder than expected. He had the use quite a bit of force to break the glue joint at each frame, so he is confident that this method is strong. John will also use this for balsa planked bottoms.

In photo # 10 you can see the stern still needs to be trimmed and sanded. John will probably use a saw to trim in close and then sand to fair it.
