I was thinking about why the toe-in offset was specified.....I'm guessing to keep it tracking straight and true and a little extra for torque?

Trying to keep the fins at 90 degrees in every axis while the epoxy set was a real chore with my B-24. I used tape and a bit of CA to tack glue them in the correct position while the epoxy set.

Should be easier if you have a tight fit that is correctly aligned already....I didn't.

Love the Lancaster......how about some pictures?
