Bolt hole spacing on standard ASA/duck bill
Anyone know the spacing between the bolt holes on a standard ASA or duck bill? I did a quick check while at the field today and it appears to be 0.700 inches. I am just wondering if anyone can confirm that measurement.
I have a project in mind for my machining class if I have time in the semester to work on it. I may even try to use it as a substitute for an assigned project.
