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.

Let me know what you find out. When I measured one at the field yesterday I just eyeballed where the centers might be. Not sure how one would find the center of a hole after it has been drilled.

Measure end to end, then subtract 1 hole diameter
or
Measure inside to inside, then add 1 hole diameter




.750" center to center

I think you'll find that a Standard ASA/Duckbill is 3/4 of an inch center to center.

You were pretty close with eye ninety method,lol.

Thank you stanchy. I will remember that trick to find distance between centers of predrilled holes.

Rolling thunder, while 3/4" and .750 are basically the same, they are different to the machinist. A 3/4" measurement has a looser tolerance than a .750" measurement. Oddly enough the decimal measurement is also more accurate than the fractional measurement.

.750" center to center

or measure front edge to front edge and subtract nothing.
