The upper wing is supported by interplane struts, one on each side. These are made up ONLY when you have the top wings in place and correctly set for dihedral and sweep and incidence (so no pressure here then !!!)
First thing – ahead of time – is to treat the pipework internally (as I have with all pipework) with Waxoyl to prevent rust etc
What a messy job this is – hey – but like those pretty gloves ! This will all dry off before I get close to in situ build and assembly.
Managed to lose some doubler plates though, must have taken them home to file, emery and etch prime and then bring back .. cant locate them anywhere so I have asked Ivor if he can send me some more in the next box.
