Student Learning Outcome:
At the conclusion of this course each passing student will be able to:
- Align a crane.
- Remove cylinder and crane endshake.
- Fit bolt ball for: optimum depth, clearing cylinder before hand hits ratchet pad and doesn’t allow rollback.
- Fit and time hand so that cylinder carries up, there is no transitional bind, and it doesn’t hinder opening and closing of cylinder.
- Fit a rebound lever so that the safety moves smoothly into place and the hammer is neutral to slightly negative with it, yet it clears the hammer in full forward position with the trigger pulled.
- Fit a hammer strut so that the hammer falls on double action as the bolt locks the cylinder, yet is doesn’t catch on the trigger as the hammer falls.
- Correct push-off and heavy let-off.
- Types of endshake, correction of endshake
- bolt fit and timing
- hand fit and timing
- cylinder-hand relationship and fit
- rebound fit and timing
- safety function, fit and timing
- safety function, fit and timing
- double action weight adjusting
- sear-trigger relationship and adjustments
- pivot pin problems and corrections
- crane alignment and adjustment
How the class works:
In lecture, we will study the various firearms and/or systems involved. To
reinforce what we have studied, assignments will be made involving repair,
refinishing, and/or modifications to the studied firearm parts. To simulate
real life situations, there will be due dates on all assignments. The assignments
will proximate problems in the field. Many times the assignments will force you
to think, i.e. I may assign the design and fabrication of a tool or parts. I will
tell you what it must do, and the tool or part must be made to work.
Everyone starts off with an “A” and everyone is expected to get an “A” for a final
grade. This is a potentially dangerous profession, so you must do the assignments
to industry standards or better.
- Everyone must have a set of finished notes by the last day of class. If they are on paper, they must be typed or written very legibly in ink, in a binder or folder, and have line drawings of systems for clarity when needed. They can also be audio, video, or on a computer disk, but if they are, they must have an index. They must also contain most of what was covered in class. If they possess all the mentioned criteria they are “A” notes. If they are missing information, inbound, or electronic with no index, your grade maybe lowered.
- Your projects must be completed in order to be graded. They will be graded on accuracy, appearance and finish.
A note on notes:
They must be good and permanent- NO PENCIL NOTES. You can get around this note
requirement by obtaining the AGI professional series course on the subject, i.e. the
shotgun course for any of the shotgun classes etc. Remember, bad notes and your grade
Method of Evaluation:
Grading in this course will be based on the following:
Class Participation and Attendance: 10%
Classroom notes: 20%
Classroom projects: 70%
90-100% = A
80-89% = B
70-79% = C
60-69% = D
below 60% = F
Incompletes and etc.:
Incompletes are at the discretion of the instructor.
NO LIVE AMMUNITION IN CLASS:
NO! NO! NO! If you need ammo to test fire a firearm, you turn it in to an
instructor UPON ENTERING THE CLASSROOM. Failure to do so will result in your
dismissal from the course.
