Paul Mccurdy (another RV-7 builder) saved me a day of work by giving
me a fully constructed wing jig that he used. Thanks Paul. So tonight I
was able to mount the left wing into the jig.
To remove twist just hang a plum bob from each end and measure. Look
close for the fish line at the outboard end.
In addition to removing twist, use something to jack up the
center and align the fish line strung from the inboard to outboard along the
holes in the spar. Thanks Dan.
