horizontal joins at bow
hull is really one of the "easier" things we
will have done. As we have no prior boatbuilding
experience ( in steel ) every little thing is a new
experience. The welding of the hull below the waterline
is a particularly touchy issue for us as, well let's face
it, we don't want any leaks!! Butt welding 2 pieces of
plate together to be strong is a different idea than
making the weld strong, sealed, and flawlessly straight
with no running off. As the welding surface changed from
horizontal to vertical, this became increasingly
difficult. For the most part, today was successful,
except for the last weld. We made 2 mistakes. One was
mine , the other was Genas.
|For the most
part, today was successful, except for the last weld. We
made 2 mistakes. One was mine , the other was Genas. As
can be seen in pic to left, my welds weren't exactly
along the center of the two plates. Some ran almost right
off and created weak points in the join. Of course we
didn't realize the magnitude of this error right away.
Gena welded from inside after I had finished the outside.
|Because this entire join
will be above the waterline, we are able to grind it down
to a smooth finish. ( Whereas under the water, it has
been recommended to leave the welds to their full
thickness ) This was when the problem showed up. The weak
welds that obviously hadn't penetrated on one side or
another, cracked away once welded from the other side.
Probably during cooling.
|Oh well! Back
to the drawing board... Gena has an idea to
"straighten" things out a bit. We'll see if it
works next weekend...this one's done!

"temporarily" welded radius to sides
