Fastenings
In 1894 Effie M. Morrissey was fastened with trunnels and iron. Iron and wood served again when Ernestina was prepared for her return to Massachusetts in 1982.
The current rehabilitation of Ernestina-Morrissey is using the traditional locust trunnels and corrosion resistant silicon-bronze fastenings. In previous posts we have described the use of trunnels as the frame came together.
Now that the sheer-strake and bullwarks are in place and the tops of the double-sawn frames have been cut to level, some cuts have exposed the trunnels used to fasten the futtocks together.
The hull frame is nearly done and drilling holes and bolting the sheer-shelf to the frame is one of the last steps.
It is important that the hole be straight to accept the silicon-bronze rod and to be centered to the end through the frame and sheer-strake so that the bolt holding the structure together will be secure. This short video shows how long the bit is and how the jig is adjusted.
As Julius said this summer, “We are getting a superior ship” thanks to the shipwrights at Bristol Marine’s Shipyard in Boothbay Harbor.
