Once again this makes me wonder why my slow build airplane is still
holding together.
I never did use "cap strips."
The process was
Clean wax/oil with an EPA disapproved (and now unavailable) paint
thinner
Clean with acetone using white lint free paper towels and lots of
them
Sand with a grit large enough to roughen, small enough to not cut thru
fibers
Clean with acetone using white lint free paper towels and lots of
them
perform one of the steps of joint closure with industrial cement (now
Hysol) or flox and/or BID.
Repeat
Just remember that the crucial part of making something stick together is
that it must be CLEAN and ROUGH (or ROUGH and CLEAN) before the adhesive is
applied. Don't forget to take the plastic off the multi-BID layups!
650 hours and I am still waiting for the first delamination!
Anywhere! My main gear over center link pivot bolt support block is still
attached to the main spar cap even after many hard landings.
