Well today I got all my ducks lined up and did another review and read to get the methods straight.
I disassembled the 85C enough for the hammer swap.
About 1 to 1.5 hours, slowly, taking notes, bagging and labeling parts, drawings and pictures.
Later in the afternoon after a break, I got the itch to continue.
I removed the disconnector (disco) from the original hammer and then went ahead and installed the disco and new strut onto the new race hammer.
I was lucky to have found a small heavy vice I had bought and forgotten.
Perfect for presssing.
The strut pin went in after starting it by using the vice.
The disco pin was easier and I did the entire install with a punch and hammer.
I used a 40 pound steel dumbell standing on its flat end as a hard platform/bench.
Then I used a metal billet that had a hole on its face and on its side.
That was my flat platform for shimming and taping the hammer onto for the pin work... another 1 hour and a bit more..
Next is the sear cage, sear swap etc.
and polishing some parts then reassemble.
Thanks Cajun Gun Works for the nice parts. !!
update,done. got insignificant to no SA creep and about 8 ounces off the SA pull, so far...need to test after some use...
UPDATE 3-23-19 after 100 rounds I retested SA pull and it looks like the CGW hammer has reduced the trigger pull by around 1 lb. 7.3 oz. from pre-hammer base line.
