Fitting the Angus Hammer
« on: July 02, 2006, 05:41:35 PM »
(The following is reposted, with permission, from a message by Jim Miossi in another area of the CZ Forum, in response to a question about problems associated with installing the competition (Angus Hobdell) hammer).
            The Angus hammer has a slightly raised sear bed so it changes the timing of the action itself. Often the disconnector needs some material to be removed from the bottom of the ears, and at the same time you should square the disconnector catch and polish the top of the trigger bar and under side of the disconnector. Then fit the hammer to the safety, do not fit the safety to the hammer or you can not go back. You should also check the engagement of the sear and the hammer hooks. I usually deepen the engagement to a minimum of 60%.
            Also check for complete free rotation around all pivot pins on the hammer and disconnector. Make sure any burs or rough spots are dressed and polished before final reassembly.

I am sorry but I disagree with Jim.
We have fitted 1000's of hammers and have NEVER found it necessary to lower the sear bed EVER.
The safety or the sear should be refitted to make the safety work with the new hammer.
We refit the safety but the sear is the cheaper part to replace if neccessary.

It is best to NEVER TOUCH the hammer, this will remove the hardness and the hammer will wear out quicker.
We have found no need to retime the gun, radiusing the ears of the disconnector is not always necessary but we do it as part of fitting the hammer, as well as polishing the "necessary" other parts of the trigger mechanism.

Angus Duhhhh!
