Basically making a new trigger blade, but using bearings for the pivot to eliminate as much play as possible and to be able to adjust the stages by using set screws in place of the roller pins. I might even alter the pivot point forward in the housing, which will change the geometry making the second stage much smoother and lighter while remaining safe.

I hope I actually finish it too. here goes.

Got some 5 x 2.5 x 2mm bearings and 2mm axle

Remove trigger unit. Note heaps of dirty grease on sears. I will polish and clean these once I've done the trigger blade.

I drill the 5mm hole for the bearing. I will work off this point as I can put the original trigger on and off as I go as a reference.

Then comes the cutting. This is just std aluminium so I can remove the rough stuff, but I just don't have any other way of cutting out the shape.

I plan to make it set back a bit more and straighter than the original.

That was it for tonight. Thought I would stop there before I either cocked it up or realised I had already made a mistake. 

Ok, so all going well at this stage. I decided to use the bearings with a flange as they took up play in the trigger housing. 6 mm aluminium + 2 x .5 mm flanges = 7 mm. Perfect fit.

Drill the first stage hole.

Then drilled the second. I tapped the thread for the first stage.

Then I started tapping the second and the tap broke.

Here's a shot of the trigger as it sits now. It works but One stage only. I will start another tomorrow.

I now have an adjustable, functioning 2 stage trigger. I think I had drilled the holes too small and the tap was gripping too much in the hole. With these ones I made the hole 2.5 mm instead of 2 mm. There was still some movement when the set screw is in place.so I gave the side a tap with the hole punch tightening up the screw.

Set screws were 3 mm.

What I like about this rekord trigger is that you can test it without being installed in the gun. The let off feels very light at this stage, but who knows, I could have spent all that time accomplishing nothing 

Don't look too close at the workmanship. Macro on the camera doesn't help.

The blade is still too long to fit in the guard so the next thing is to cut it off, then tidy it up as much as possible. I will polish the sears then refit the unit for field testing.

Not that the Rekord ever felt bad, but I think I like the change. So I will just shoot it for a while before I go changing the position of the trigger axle forward. The let off just goes now, where before there was a slight resistance, then a crisp release, so I must have changed the geometry enough to safely lighten it.

To test it, I loaded the gun, took safety off and struck the butt with a rubber mallet a few times and it never went off, so I'm happy.

You can see the two adjustment screw holes, 1st and second stage easily accessible while fitted.

I will take it out and polish it up after I've shot some stuff with it.

 

And that's it.

If I made one that is set back anymore I would have to change the trigger weight screw out for a shorter one.
