It works pretty much the same as the other adjustable triggers on the market for the XS19/B19 type air rifles, so I can't take credit for the basic concept, but the measurements are not the same as any for sale out there, either. I usually buy these, but I had some 1/4" thick 6061 aluminum plate lying around and its fun to make your own parts. Now to see if it works properly.

How did you achieve the finish on the trigger face?   Posted: Tue Feb 05, 2013 3:57 pm Slavia Moderator Joined: 31 Mar 2008 Posts: 4382 Location: Waseca, Minnesota, USA Looks beautiful - same question about the trigger face. _________________ ¡Listo! ¡Apunte! ¡Fuego!   Posted: Tue Feb 05, 2013 7:12 pm cjs Member Joined: 02 Jan 2008 Posts: 62 I am guessing, tape up the majority of the trigger and sand/media blast it........   Posted: Tue Feb 05, 2013 9:18 pm SMP Silver Status Member Joined: 04 Feb 2011 Posts: 1183 Location: Just south of "Out There"- Land O Lakes Ontario That is simply BAD A$$ Nice bloody job! _________________ Sean   Posted: Tue Feb 05, 2013 10:56 pm radar Silver Status Member Joined: 13 Nov 2011 Posts: 1138 Location: Des Moines, Iowa, USA Thanks fellas. I used an electric engraver from Sears like you put your initials on your tools. Tape off the area. Little overlapping circles. Then bigger circles. 800 grit wet sanding lightly, a rub with 0000 steel wool. I just wanted something different than the old vertical grooves. cheers Rob _________________ It's never too late to have a happy childhood.   Posted: Wed Feb 06, 2013 11:41 am Slavia Moderator Joined: 31 Mar 2008 Posts: 4382 Location: Waseca, Minnesota, USA Quote: I used an electric engraver from Sears like you put your initials on your tools.

I have been dragging a tap sideways to make the "old vertical grooves," but this looks like a technique I could use. Good thinking. _________________ ¡Listo! ¡Apunte! ¡Fuego!   Posted: Thu Feb 07, 2013 8:44 am radar Silver Status Member Joined: 13 Nov 2011 Posts: 1138 Location: Des Moines, Iowa, USA Thanks. I like your idea, too. I was doing to restrain a dremel tool and do the grooves one at a time with a cut-off wheel when I decided to try this sandblasted look. _________________ It's never too late to have a happy childhood.   Posted: Thu Feb 07, 2013 1:48 pm robert w Senior Member Joined: 12 Feb 2012 Posts: 574 Location: usa radar , that looks very well done. i see your a good machinest . and i still havent broke that big cat down yet. might today as im not workin, got rained out _________________ ,crosman 400,gamo big cat in .22, diana 5g,diana 54 air king, diana 34 in .22 diana 34 in .177, wilrauch hw-55,and a romainian pioner training rifle , and a huge collection of powder burners 35 last count . 1 would think i have a gun store   Posted: Thu Feb 07, 2013 9:30 pm radar Silver Status Member Joined: 13 Nov 2011 Posts: 1138 Location: Des Moines, Iowa, USA Thanks Robert but its more fab than machined. Just the cutout was milled, drill press the holes and slot and lots of hand finishing. I'd need better tools to mass produce, and I'll leave that to Charlie Da Tuna and Airguns of AZ. Didja get your other stuff squared away? _________________ It's never too late to have a happy childhood.   Posted: Sun Feb 10, 2013 10:04 pm radar Silver Status Member Joined: 13 Nov 2011 Posts: 1138 Location: Des Moines, Iowa, USA Finally around to finishing this project. It shoots as sweet as any aftermarket trigger. Crisp and light. That was fun. _________________ It's never too late to have a happy childhood.   Posted: Mon Feb 11, 2013 6:20 am ZipSnipe Veteran Member Joined: 09 Mar 2012 Posts: 327 good job !! what did you use a 6-32 tap ? _________________ You can have tomorrow, I'll take yesterday !!!   Posted: Mon Feb 11, 2013 8:35 am radar Silver Status Member Joined: 13 Nov 2011 Posts: 1138 Location: Des Moines, Iowa, USA Thank you. 3 x 0.5mm thread. 6 was too big and coarse, 4 is not readily available, so I went metric. _________________ It's never too late to have a happy childhood.   Posted: Mon Feb 11, 2013 9:23 am Slavia Moderator Joined: 31 Mar 2008 Posts: 4382 Location: Waseca, Minnesota, USA Quote: 3 x 0.5mm thread. 6 was too big and coarse, 4 is not readily available, so I went metric. Plus you get finer threads, so adjustment is easier. 4-40 would be 0.025" per turn, 6-32 would be 0.031," and 3X0.5mm would be only 0.020." Did you use Loctite, teflon tape, or anything like that? Crispness and accuracy = good. Self satisfaction = also good. Having the guys at the range drool and blink when you say you just whipped it out one day = priceless. Very nice. _________________ ¡Listo! ¡Apunte! ¡Fuego!   Posted: Mon Feb 11, 2013 10:37 am radar Silver Status Member Joined: 13 Nov 2011 Posts: 1138 Location: Des Moines, Iowa, USA Slavia wrote: Crispness and accuracy = good.

Time will tell if that works. I have also rounded and smoothed the contacting ends of the adjuster screws for better operation since the pictures were taken.
