Exactly the right approach Paul! When I do this stuff, once I know where the error is and why ... I have no problem at all contouring the forms a bit by sanding off material or by adding material ... or by tweaking whatever is necessary. IMO it also shouldn't be assumed that all plans are accurate ... I've found errors in almost every plan I've used ... so it pays to think a bit, measure this and that, check fairness with a batten etc. before ya conclude what the problem is and how ya wanna fix it.

: I'm wondering how you measured this to determine the error. I am
: also wondering if we are getting the correct idea of where the
: error is located.
: Is it possible the centerline is simply off by 1/16th?
: Are the curves symmetrical, or mis-shaped?
: If you trace this form on a piece of paper and then flip the form
: does it still fit in the same outline? If not, can you shim or
: trim it to be symmetrical?
: Do you have paper plans or offsets from which you can draw up what
: the proper form should look like, and then see if the form you
: have fits that outline?
: Obviously if the form is bad you should call the manufacturer and
: get it replaced.

: Just curious about how this happened.
