Today I finally got that Kepplinger trigger and the scelletonized hammer installed. Had some problems with the hammer they are not quite the same and the loading ramp is a shade too high but it works ok. I have to do the milling on the original hammer which was fitted at the factory.
Ruger says hammers must be fitted at the factory, now I know why! The original hammer spring is fine with lighter hammer.
Since the hammer strut fit into the hammer the recess in the hammer must hve been a bit shallow. Because of that I could not get the spring/strut unit back in. Drilled a new slave hole and compressed the sprin and washer in the vice.
The washer slipped off the vise and went into orbit never to be found again. Made a new washer by hand including the two studs on the washer to fit into the slot to keep the pring in place. I had not planned on that job.
The Kepplinger trigger was short in height by 0.024" to reach the underside of the sear arm. This is a bit of a dilemma. So I made a shim 0.113x0.600x0.025deep. I just wanted to try it and glued it to the underside of the sear arm with 51High tech epoxy.
If it works I will solder the shim at a later date.
The adjusting of the set trigger takes a bit of fiddling since the set screw function is not very well explained. As right now the primary trigger pull is 320z and the set pull about 4-5oz. That is pretty good.
One thing the sear notch in the hammer will have to be honed to at least 35oz since the Kepplinger trigger does not adjust the initial pull weight.
Once you adjust the pull weight to 32oz by stoning the hammer notch the Kepplinger trigger is not really needed. . That what I did with all my other #1 Rugers. A 2lbs trigger pull is very good on a hunting rifle. The Kepplinger trigger is smooth and works well once you got it well installed.
