Small Craft Build: Frame setup, beveling frames and stem

For the small craft build we build a 3.5m dory, a dory that i have the benefit of owning.

We started out the build by seting up the frames on a big building base that was fastened to the floor so that when we were working on the boat it wouldn't move and be annoying.  There were 7 frames all together and they had to be setup correctly, level and correct distance apart.  To achieve level frames we started with the setting up of the very first frame and worked our way from there, the first frame was set up by measuring out so that we have it in a good position and then marking where it will go and getting a spirit leve to get the frame plumb.  From there we were able to get up the other frames level and the right distance.

After getting all the frames up we had to bevel the frames.  The reason for beveling the frames is that when you are bending wood around a frames, the frame is square, but the wood that gets bent around is not, it has a shape to it so we had to make sure that the frames have that shape or the ply wood would have dents or dings in it.

The stem was the first part of the boat that we made, the stem is a bit of wood that takes the shape of the forward part of the boat and heaps hold the strake and garboard of the boat.  To make the stem we made up a jig so that when we have the wood ready we could use it to hold the wood.  To get the shape of the stem we took a print out of the stem from the autocad file and built the jig around the print out.  There were  6 or 7 plants of wood, the wood was placed into the steaming pipes and the were steamed.  The planks were steamed because the stem has to take on a compicated shape and steaming the wood heaps it bend much more easier and when the wood cools down it holds most of its shape.  When the wood has cooled down and has held its shape a bit more then we would apply some epoxy to the wood and glue it all up.
