Re: Europa-List: Mod 61 - Stall warner question

The welding wire is meant to ''find'' the position of the rib, and you  
''eyeball'' down the exposed portion of the wire, as you would a snooker cue, 
and 
extend that line onto the upper wing skin, to the L / E.
A powerfull light shining through the hole in the spar, [ with a blanket  
over your head, onto the leading edge area, as a Victorian photographer would 

have done] will also find you the rib position,,, ie the Redux bond line shows

up as a dark shadow.
Cheers,
