Any Boss trigger experts?

[Glem.Chally]

I have a Boss trigger that I'm trying to assemble. I had it cocking and working but second stage was mushy so maybe I tried to adjust it a bit and now it will not cock when assembled. I spent hours on it last night, there's a good Ernest video that I used for reference.

With the trigger house not attached to the block it works fine, cocks and releases. (This is on the Royale but same thing on Boss)

They sent two springs so I cut one shorter and have tried with both the shortened spring and the normal length. 

But as soon as I put the trigger house on, (Still waiting for proper screws, disregard weird looking screws they are the right thread) look how high that part E4 is. If this is its relaxed position (not cocked)

This is cocked and its even higher of course, but as soon as I lower this part at all to assemble it will not cock anymore, not even close.

Now look at Ernests video at 11:25, he's able to get it to this point in assembly and part E4 is able to lay low enough so that assembling it doesn't affect its ability to cock.

Again I've tried with both the factory length spring and a shortened one, what am I doing wrong?



Part E4 as shown here is what I'm referring to. http://www.fxairguns.com/wp-content/uploads/2014/03/FX-Boss.pdf

I think the screw on the second blade is too far in, unscrew it with 1/8 turns and test again. While testing push that middle blade down to the point it's about parallel with the top of the trigger housing and see if it cocks. Small finetuning should be done with the top blade attached.

Hey Broekzwans

The screw on the second blade is backed out to the point its doing nothing to the rocking plate below (E12), and if I arrange that second blade to be parallel to the top of the trigger house it won't even come close to cocking. 

There is also nothing wrong with the sear as I've put my Royale trigger assembly on the Boss with no issues.

Are the spring, sear and trigger roll oriented in the same way as in the picture below?

If the settings of the trigger are completely out of order it's a bit of fiddling to get them back together in a decent way again.



I've made a quick and rough drawing of how the trigger is build up:

screw 1 is just to hold the spring in place (for making it easier for yourself just use the spring that's supplied with the trigger). Screw number two is to position the bottom plate in such a way that when the gun is cocked the trigger roll catches the sear which holds the hammer, when you pull the trigger the trigger roll will move towards the round cutout which releases the sear. The blade with screw number two will point a little bit upwards when the whole trigger assembly is put together and the gun is cocked. With the the screws number 3 and 4 you adjust the feel of your first and second stage (don't know a better way to describe this at the moment) and with screw number 5 you define most of the length of the first stage.

Hope this gives a bit of a visual way of what is adjusted with what screw and might help in adjusting it.

Yeah same way although my parts look a bit different. Thanks very much for the great diagram and detailed write-up, I'll tinker a bit more with it later.

The first picture I posted was my previous crown trigger but the sear, spring and trigger roll have the same orientation. Hopefully it works out, keep us posted

Got it sorted thanks Broekzwans

Cocked and staying cocked and adjusted beautifully, what a pain in the ass haha.
