ddc Posted July 15 Share Posted July 15 During the initial fitting of the thumb safety I'm taking off the minimum necessary to get the safety fully inserted. At that point there is a fair amount of resistance to rotation. (This is with the thumb safety detent and associated spring removed.) As I remove more material it becomes easier to rotate the safety into the full on position. At what point do you stop removing material? Should there be a slight bit of resistance as it approaches it's full on position? More? None? The above assumes that all the thumb safety tests pass successfully of course...

caspian guy Posted July 16 Share Posted July 16 https://www.brazoscustom.com/post/fitting-an-ambi-safety This one is good too... Link to comment Share on other sites More sharing options...
ddc Posted July 16 Author Share Posted July 16 Thanks guys. I actually read both of those but overlooked where Brazos says: "Remove a little material where the safety is marked and try again. You should eventually get to the point where the safety engages with just a little resistance – this is good." I think that answers my question.

caspian guy Posted July 16 Share Posted July 16 Yea Bob (at Brazos) is one of the best gunsmiths around. There were a whole series of those articles that were published in Front Sight (I found the articles about extractor and ejector fitting and tuning super helpful as well. ) Link to comment Share on other sites More sharing options...

zzt Posted July 16 Share Posted July 16 A 10-8 armorers block is a very useful tool. It makes fitting a thumb safety easy. Armorer Block, 1911/2011 - 10-8 Performance Link to comment Share on other sites More sharing options...

shred Posted July 17 Share Posted July 17 Bob has a thing at that link right at the end about saving slightly-over-cut safeties so don't trash them right away (I have a small heap and every now and then also can re-cut one to fit a new sear). Not only is he an excellent gunsmith but he's also deep in the competition world. Link to comment Share on other sites More sharing options...

A bit longer sear replacement and your in business with having to re-fit that previous safety! Link to comment Share on other sites More sharing options...
barry Posted July 17 Share Posted July 17 A good tig welder can always save a over cut safety also. Link to comment Share on other sites More sharing options...
