Micrometer Reamer Stop
Precision, repeat-ability, and ease of use: these are the benefits of P. O. Ackley Micrometer Reamer Stop. Now you can do production runs with your Chamber Reamer, without having to index each workpiece axially. You’ll be assured of consistent headspace, chamber after chamber!
To set up, insert your Chamber Reamer shank in the Reamer Holder and tighten the two set screws. Then insert the reamer holder into the Stop Cylinder assembly (micrometer threaded Stop Cylinder with .001″ Adjustment Nut, Lock Nut and optional Plug Nut). Make a rough cut in the chamber (leave about .025″ extra material). Now, with the reamer bottomed in the rough chamber, move the Stop Cylinder assembly into contact with the work piece and secure it to the Reamer Holder with three set screws.
You can now adjust the depth of the finish cut in increments of .001″, or even less. The Adjustment Nut is marked with 25 equidistant markings around the circumference, each of which corresponds to .001″ of axial adjustment. By backing off the Adjustment Nut and re-securing the Lock Nut, then repeating the cut, you can zero in on your specified headspace measurement. Adjustments of .0005″ can be made with confidence.
We recommend use with our floating reamer holders for best results, with this rental.

$24.95
Gunsmithing Student Handbook Series #1
This booklet is the first of many planned works that provide instruction in the correct and safe methods of gunsmithing. Specifically, this essay discusses Ackley Improved cartridges. In it, we will not teach you how to install and chamber a barrel, we handle that information in another title, “Chambering Rifle Barrels for Accuracy”. In this book we will in detail help you to understand the special details related to chambering for Ackley Improved designs, specifically we explain headspace for Ackley designs.
If you are not familiar with how headspace applies to firearms and ammunition you may want to consider another title we offer, “Understanding Headspace for Firearms”.
Fred Zeglin along with other well-known Gunsmiths has begun the task of creating a series of instructional manuals. Each book will focus on one narrow subject in Gunsmithing. Written with an audience in mind who want to know every detail of the how and why of gunsmithing.
Each book in the series will provide a highly detailed and Technical explanation of the subject at hand in a way that any gun lover will be able to understand, whether professional or hobbyist.
