bruno22rf Posted May 22, 2017 Report Share Posted May 22, 2017 Wood looks like a far nicer piece than the Walnut on the one I sold - mine would have taken serious skill to make it pretty enough to be worth burning. Quote Link to comment Share on other sites More sharing options...

It would appear you are suggesting Ditchman wouldn't have the skill required! Quote Link to comment Share on other sites More sharing options...
ditchman Posted May 22, 2017 Author Report Share Posted May 22, 2017 Sort of tuning /cleaning polishing the trigger mech'........i have laid it out so you can see how it sits....with the piston/capture shaft thro to the trigger body....then the sear and onto the sear the trigger strut....

ditchman Posted May 22, 2017 Author Report Share Posted May 22, 2017 first pic...the trigger strut sitting firmly into the sear...... 2nd pic...the strut trigger spring...this gives you the resitance on the play/travel of the trigger 3rd pic....is the sear spring engaging the sear and in turn the sear locking onto the piston shaft...(cocked position) 4th pic ...is the piston about to slide into the trigger (uncocked body) Quote Link to comment Share on other sites More sharing options...
ditchman Posted May 22, 2017 Author Report Share Posted May 22, 2017 #1...trigger body waiting to receive the piston shaft...(vilking will be along shortly) #2...sear has moved up and trigger strut has engaged #3 ..close up of engaged sear and strut...(fully engaged) #4..this is the strut adjustment screw...you screw it in to lessen the bite on the sear...(so there is less travel for the trigger) #5...this is the strut spring and behind it is the adjusting screw...(screw in the tighten the bite...screw out to lighten the bite) Quote Link to comment Share on other sites More sharing options...
ditchman Posted May 22, 2017 Author Report Share Posted May 22, 2017 (edited) a little bit more oil on today......just a few drops at a time and use the ball of your hand to work up the heat...it will nearly burn you if you are doing it right.... just out of interest for a few... swept volumn of pressure chamber 2.48cubic"......or near enuff...40cubic cm gap between breech and chamber 14thou.....(this is where the breech seal comes into play) Edited May 22, 2017 by ditchman Quote Link to comment Share on other sites More sharing options...

Rimfireboy Posted May 22, 2017 Report Share Posted May 22, 2017 Wood looks like a far nicer piece than the Walnut on the one I sold - mine would have taken serious skill to make it pretty enough to be worth burning. Indeed, and the stock on my airsporter'S' was the plainest piece of walnut I've ever seen. The pressed chequering was a joke as well, with one side noticeably deeper than the other. Of the many pellets I tried,it was only accurate with the old eley wasps. Otherwise it was disappointingly ok ish,not as nice as a mk1 or mk2 though. I would have another one of them at the right money. This Mercury is looking good though. Quote Link to comment Share on other sites More sharing options...
