The trigger on my mercury S is ok, but no real feel no matter what i do to it.
Have to rely on how the pressure feels to judge when in breaks.

So, i decided to try something. Not fitted it to the gun yet but in the block it feels good.

I had to make a new trigger blade, the originals are either plastic, or cast alloy. The cast ones dont have enough meat to play with.

So, on the kitchen floor, with hacksaw, files, electric drill and a vice thats not bolted down, i hacked out a new blade (will be removed again for final finishing).

On the new blade i made the roll pin hole larger so the blade pivots before it moves the strut.
I then drilled the blade for a grub screw and put a spring in it. Spring bears against the underneath of the strut and is adjustable.

So now i have a fixed throw, but pressure adjustable first stage and i can set a heavier, short throw second stage.

If i'd set the original trigger up with just a heavy, short single stage i wouldnt have confidence in it, so at least this way i can take up slack and when i feel the stop i know the smallest pull and the trigger will break.

Its the same idea, but done in a different way, to the early MK1 airsporters.

Heres a pic.


This block dosnt have the length of pull adjuster for the trigger, but the one in the gun has.

Will be interesting to see what it shoots like.

One last job now is to smooth the block out so it flows properly from the cylinder.
Why does my MK1 airsporters block flow nicely but the later ones have 2 'ridges' and are a bit too large?
