Fuselage (page 19)
This photo is of the prototype during the
earlier phases of construction.
Here's the second crack I spotted. This is the joint between
the lower main longeron and one of the major bulkheads.
I went looking for more cracks and unfortunately found some!
This crack was the result of twisting the bulkhead with one hand.
This was the first bad joint I found after it is all cleaned out and ready to re-glue.
I've been using West Systems epoxy and am very
surprised to see these joints failing like this. They have a
fantastic product and excellent tech support so I will be
calling them to get their advice on how this might have
happened and what to do about it. I have no doubt that
its something I've done and nothing to do with their
product. I suspect its either the result of steaming the
joint after it set, or the glue may have exceeded its shelf
life. It could have to do with curing temperatures in my
shop? I'm anxious to hear what they have to say.

November 9 2009 0.5hrs - 765.5 total. Called West
Systems and discussed problem. They are very
concerned about the cracks and think I am probably not
using their product. They want me to send a sample for
them to test.
