Welding the Frames

 

Here is the initial placement of the aft area of the frames.  Spacing is 18 inches on center.  Below is where the batteries and motor will be.

Looking from the stern to the bow.   All the frames are hanging from above, along a straight line.  The "T" bars which the frames are hanging on are temporary and are used to align everything.  On the top of the "T" bars are welded a threaded rod so that each frame can be adjusted up or down. 

Here are the frames just after fabrication.  Top and bottom had to be constructed separately to gain access to the interior area for plastering.
Here is the bow section with the "T" bars.
Frames ready to be connected together with wire.
