||Putting up 6th
|Putting on the
radius plate opposite the one we finished on Day 32
should have been a cinch as we had the method of the
other fresh in mind. It didn't act in the same way and
was a whole different experience! We discovered the plate
was flat in an area a few inches long, and that caused
some strange problems while being curved. Initially all
looked fair, but as we pulled the aft end into the
frames, the bottom of the plate buckled as it did on the
other side. We were ready for that and took measures
included pulling in at a higher angle and stratigically
clamping at stress points. Suddenly we noticed ripples
forming a shorter buckling sections in and out, as if the
plate had nowhere to go. If you look above the clamps you
can see two of them in photo at right. Anyway, this was
the result of a flat section in the rolled plate that
just happened to be just above the splitting point.
bottom piece was ok and fair. As can be seen in the top
photo, things eventually came in ok. There are still a
few problems to iron out ( ..if only we could just iron
them out ha ha! ) with that section. The center of the
curve has pulled away from the frames as a result of the
flat section. This will have to be remedied on the next
opertunity available. The very ends of the two are almost
too closely butted and may cone out.
||Have we learned
Perhaps the starting end of the plate before curving and
pulling in should be held in place only with clamps, or
non-permanent means that would allow for some movement.
Or maybe just some tacks around the center. We tended to
assume everything was running in ok if it appeared ok on
first glance, then start tacking along, until we noticed
problems. Then the tacks would have to be cut off etc
distortions in the plate can be worked out easily enough,
it's just annoying to see it happen! Some obvious things
also caused problems over the last couple of days
including tacking all down one side only. Sometimes it
works, sometimes it doesn't. Overall we're a little wiser
to the ways of steel plate.
Marked, cut, ground, and fit on split plate, (radius section 6)
yes it really did take all day!
us build any time!
