Which Trigger Replacement?

[LDSILLS]

Are you talking about an Accutrigger or a 3-screw trigger? Not sure which screw you are speaking of, but some of what you’re saying sounds a bit confusing. An Accutrigger has no Overtravel stop screw. It has a Trigger Spring Adjustment screw, and a Safety adjustment screw. The 3-screw trigger does have an Overtravel stop screw. There is the Sear Adjustment screw in front; the Safety adjustment screw in the rear & the screw in the middle is the Overtravel stop adjustment. It is a true Overtravel stop adjustment. If you you are referring to the screw in the Safety Bar, that is not an Overtravel Stop screw, nor is it a Safety adjustment screw. It is adjusted to maintain the height placement of the Bar and keeping it parallel to the Trigger. It does control smooth operation of the safety.


Circled in red is the screw I am talking about. It can be adjusted and it's covered with a plastic plug. Once you remove the plastic plug it has an allen head that can be adjusted to set the safety timing. It works as I described above. I am sure many people think this is a Trigger Overtravel Screw as I have found no photos where its described.

Right.. Ok. Just that you called it an Overtravel screw, & confused me what you meant. That is the Trigger Safety adjustment screw. I’ve never heard anyone call it an overtravel actually. But yes, you were correct in it’s operation.

One of my posts earlier, I actually showed how I added a True Overtravel Stop screw to my Target Accutrigger. I also included an Overtravel Stop in my standard Accutrigger jobs as well. My standard Accutrigger below using custom spring & set screw/Overstop.

Installing my new Red Blade Target Trigger yesterday. Thought I would show you all this. Its my measured difference with micrometer of the of "OLD" Accutrigger vs "NEW" Target Red Blade trigger return
springs.

I also was trying to determine other differences in between the "OLD" Accutrigger vs "NEW" Target Red Blade trigger. Har to see in the photo but it appears the "NEW" Target Red Blade trigger sear face angle is 15 degrees as measured with my Loupe Magnifier. The "OLD" Accutrigger trigger sear face is near 5 degrees. Note these are guesstimate as with my cataract ridden eyes I don't see like normal eyes. However there was a noticeable difference.

Picts not great nor is it accuate vs what I would align with just manipulation of the magnifier. I took it with my cell phone whilst holding everything steady. But its representative of what it looks like through the Loupe Jewelry Magnifier with Scale lens installed with sear in background.

Yeah, we’ve discussed this before in the past. 15 degrees & I believe the standard Accutrigger is 25 degree escape angle. The springs are also thinner diameter wire for both compared to those of the standard Accutrigger.


Edit: Sorry, my bad. It’s the other way around. Standard is 15 degrees, Target is 25 degrees. But apparently, you need one of these in the picture to be able to tell the difference. None of this is from me directly. Just what’s been said here.

Dave the nice thing is I am confirming I am on the right path. Also I found this post from 2018 you made!

Sorry for not searching for a thread on sear angles and trigger sear groove depth. I know my photo doesn't do it justice but yes through the Loupe Magnifier I can determine an actual actual angle similar to the machine picture.


Lastly my Loupe magnifier is more than 25 years old,however I just did an internet search and you can get yourself one with similar reticles on amazon for $40.00. The new ones appear nicer as they are back lit.

I changed my post. After some thought I was getting off subject with little value added....sorry!

Bought Elements 8, years back for $80 and moved it from old to new computer a couple times.
It gets used for lots of things.

Like removing frown lines from pictures of the wife :)
I take a lot of pictures and crop/resize/color/etc.

Some of the best photos posted on here in a long time.( at least from a technical perspective)

I agree. Digital cameras have change a lot how we do things.

I've also used video to diagnose problems. Can edit them to very low speeds to go frame by frame. Or, in some cases run at higher speeds to see where a problem occurs.

A collimated view with an optical comparator gets rid of angle/parallax issues in view but good alignment with a macro focusing digital camera (even some good phones) is a quick way to help old eyes. Lighting and alignment are critical for sharp accurate images. Zoom allows you to change perspective and depth.
I like the version of Photoshop-Elements I have. Lacks some features but the image translation, rotation, and sizing are surprisingly accurate.
Got a label you can't read the small print? Snap, view on the big screen.

I don't know what camera/phone Dave uses but some of his pics are sharp.

Is there any major difference in working on a Model 11 bottom bolt release standard accutrigger?

Compared to what? And what type of “work”?

Obviously the sear is different but the triggers themselves should be the same as a top bolt release.

Those with HIGH trigger force, is it Blade Force, Trigger Force, or Drag?
My Finger is NOT as calibrated as some to feel so I use a Trigger Pull Gauge.

The spring scale gauge is fine for pulls in the 1+ pound pull but the Digital reads LIGHT pulls better.

The Blade force is applied through a lever at a reduced ratio to the Trigger.
To KNOW what your Trigger is doing it might be necessary to actually measure both.

What would be an appropriate Ratio of Blade to Total to be SAFE?
For example, an 8oz Blade force with force applied directly to the Trigger, and a 10oz Total force.
Is that getting close to tripping the Trigger?10574

Obviously the sear is different but the triggers themselves should be the same as a top bolt release. Disregard. I thought the screw was fixed because of the sealant. This is the first accutrigger I've ever delt with. I know now to remove the sealant, Duh!
