Bix trigger fix

[Alex Wheeler]

These triggers are extremely simple in design. They are also extremely reliable so long as things are how they should be. A little over a year ago I had enough issues with them that I looked into it and came up with the solution. I have been doing this on every rifle I have built for a little over a year now and have not had one come back with a failure since. I have also been doing it for guys that have had trouble and all the reports have been good so I know this works. Early on I also replaced the ball bearings with carbide but have concluded that did nothing, and stopped that practice with no ill effects. If you look at the friction surfaces in the trigger you will find that there is really only one. That interface has got to be polished to a mirror finish or you may have problems. If you pull the trigger and nothing happens until you touch your bolt handle or get delayed fires this is why. The first two pictures are pointing to that friction point between the 2 parts both surfaces need to be polished the next pictures are before & after. You wont have to clean your trigger again after you fix the actual problem. This is not meant to be a negative thing, I use mostly Bix n Andy triggers in my builds, probably 90% or more. They are my favorite trigger.

Alex,
Thanks for the info and pics. Fortunately, both of the surfaces are easy to get to and polish. I'll be doing two this evening.

Is this an issue with all BnA triggers or just the super light competition triggers?

Wondering because i haven’t had an issues with my TacSport Pro yet. Not sure if the design is the same.

 

[Alex Wheeler]

It's just on the bench rest model. You can tell if you are going to have problems by holding the trigger back and pushing down on the top lever. If the top lever drops smoothly all the way down you probably are OK if it hangs up and clicks on the way down you have to polish. I just do them all to be sure.

I have been doing this on every rifle I have built for a little over a year now and have not had one come back with a failure since. I have also been doing it for guys that have had trouble and all the reports have been good so I know this works. It also does not affect trigger timing. If you look at the friction surfaces in the trigger you will find that there Is only one. That interface has got to be polished to a mirror finish or you will have the problems that everyone has experienced.

Great information, thanks for the post Alex!

Great info Alex! I had a BnA crap out on me at the recent Group Nationals in St Louis. Definitely caused a pucker.

Are you using a whetstone to polish or perhaps a fine grit paper? Also, from your pictures, it appears the contact points on both widgets are polished?

Thanks!

 

[Alex Wheeler]

I use a hard felt wheel with rouge on it. You could use an extremely fine stone. Yes, both points of contact get polished. Check you work by pushing down the top lever with the trigger held back, should be smooth, no click.

I am gong to check all four of mine tomorrow.

I have one, and during the first year I had it, it started doing a "click-bang". Felt like I was shooting a flintlock. I took it off between matches, took the cover off and cleaned it with carb cleaner. It worked OK after that. I took it apart this morning and did the polishing as shown. I'll shoot it Saturday and see how it does, feels OK for now.

Awesome @Alex Wheeler ... thanks for sharing!!

Thanks @Alex Wheeler , I retired several Bixn'Andy triggers in favor of Jewell's because of the exact issue you describe. I have all the proper equipment for polishing small metal objects so maybe I can bring them back into service.

 

[okie]

what is the advantage over a jewel?? just asking...

 

[Dusty Stevens]

Good job alex. Not much worse than shooting a flintlock at a match

 

[moondog]

Never had a problem with mine on a Kelbly's 6BRA. Now I will! Guess I should be proactive and polish it.

 

[Badbob]

Thanks for posting this! I truly appreciate you making public your findings and your fix. You certainly could have kept this to yourself and even capitalized off of the fix.

 

[wkdickinson]

Maybe this question will show my ignorance. If so, I'm sure someone will point it out. But it seems the question should be - why do you have to do anything to a top-of-the-line, expensive trigger to make it work correctly, isn't that why they are expensive?

 

[BigBlueandGoldie]

I do find it funny the Alex was able to come up with the "fix" that B&A's team of engineers and manufacturing people couldn't figure out./failed to implement.

I understand that there are many things a top smith has to keep to himself, but I always appreciate when you share your knowledge and techniques with us! .......and I don't even own a B&A.

percentages. there's no money in a company putting time into investigating and fixing a problem that might only affect a tiny percentage of users, if they even bother to recognize a problem at all.

luckily we have gunsmiths like Alex who are not satisfied with the possibility of "only affects a tiny percentage" to suss this stuff out.

This problem doesn’t speak well of Bix & Andy quality control , understanding of their product , and pride in manufacturing.

Lets keep this positive, if the bashing starts it will go away.
