Bix trigger fix

Alex Wheeler said:
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.

Would a little oil applied with a Q-tip help even if it's polished. Seems like a critical part should have some lube. The theory of clean with lighter fluid and let dry, no lube necessary always puzzled me. I worked in research for an oil co.

Polished and dry contact is consistent. Oil will be inconsistent.

Why would oil be inconsistant. That's an asumption. Even if the oil came off you would still have your polished surface. Jewel always said that if you clean with lighter fluid and let it dry there is enough remaining chemicals to provide lubrication. Oil would give a much better lube. I don't know if it could get moved off of the contact area completlly.

The parts need to move with very little resistance. Even an oil film could be an issue. You can give it a try but Id wipe the oil off, I would not leave a visible film.

I don't know how you determine if it works. The gun always goes bang.

It can be measured with an indicator. Trigger set point at cocked will vary more with lubricant added than dry. A person can determine when its time to take down and clean the trigger from this as well before the normal failures a Bix will see from being to dirty as well. It will affect ignition long before it quits going bang.

This works great!!! Thank you for sharing with us Sir!!
 
On my second barrel on my BRA. Did some musical chairs with scopes and decided to take a peek and clean the Bix.
Never had a problem with it but did the polish anyway. It does feel better to me and if nothing else, gives me peace of mind.
 
Ran into the issue described in this thread this past weekend with my bix n andy comp that was purchased about 2 years ago, but only when the temps would drop below freezing. Would pull the trigger and have to keep it pulled and just wait for it to go off. After polishing the edges described here, the trigger feels a lot smoother and runs perfectly after sitting the freezer for a day.
