Jewell trigger - has it been timed?

[jawjaboy]

After watching Erik's video with Speedy "Speedy tells his Benchrest secrets!", I'm wondering how can you determine if your Jewell trigger is/was timed (if that's the right terminology for the sear dwell time adjustment)? Since I no longer have contact with the smith that built my F-Class rig I can't ask. At the time I just went with his recommendations for barreling, chambering, action truing of my action, as well as sending in my jewell trigger with the job.

This might be a stupid question but since, in spite of me, the rig hammered, before chunking out that trigger for another trigger that accounts for the sear dwell time in it's release design, I'll like to try and figure it out.

Thanks

Update: To clarify my question, I'm asking about how to determine if the sear bar rebound timing has been tuned to allow the cocking piece to move forward past the sear bar before it resets.

The Bix can be timing adjusted. Is it like a Jewel?

 

[butchlambert]

Time adjusted?? I don't have to look at a clock, just pull the trigger on my Jewell.

I believe that the modification may be unique to Speedy. You can probably determine if your trigger has been modified by taking the side plate off and comparing what you see to a factory picture of what you are looking at. Just a little aside, lots of fine groups have been shot with unmodified Jewel triggers. I think that timing is not the word for what you are asking about. In the RH illustration the part that is not shown is the cocking piece bearing on the sear, which is what what would be holding the triger's parts in the position shown. As the bolt is opened and moved to the rear, the cocking piece comes off of the sear and its spring resets the trigger.

Mark Penrod did "his" mods to my Jewell. I have the utmost trust in Mark..

 

[butchlambert]

So your Jewell has been trued or timed to your bolt as your trade off bolt to trigger is satisfactory to you and and not excessive on cock on closing. That is what most are concerned on is the force of closing of the bolt and not having to hold the rifle from twisting when closing the bolt.

Never experienced this and have now and in the past at least 25 Jewell's. Thou my Wife said that I was not sensitive.

 

[butchlambert]

But you just "said"

Mark does this as part of his rimfire builds. Did it help? I don't know.

 

[butchlambert]

Well its nice to know that you are talking Rimfire and not Centerfire.

Young feller, what difference does it make? I use the same Jewell on my CF and RF. They ain't any difference.


God gave us two ears and only one mouth for a reason, To listen twice as much as talking.

@BoydAllen Yes timing isn't correct for what I'm asking. I know it wan't modified to minimize or eliminate cocking on closing. What I'm wondering is was it tuned for the dwell time of the sear bar reset to occur after the cocking had passed as to not kick up the bolt's rear as Speedy described in the video. My understanding from the video later aftermarket triggers take that into account. I definitely like the Jewell. Just curious if mine was tuned for dwell time.

 

[butchlambert]

And you do a lot of talking. Young fellow I was waiting for that one, Biden is old to. Are you sure you want to put yourself in that group..But he's not as old as you, correct

Young feller, I just asked a question as to what difference does it matter whether it was RF or CF. When I ordered my Jewell triggers they're not a check box for Rf or CF. I'm sorry if you seemed to think I pissed in your Cheerios.

 

[butchlambert]

The camming force on a CF and a RF are completely different. Rimfire you do not want to crush the primer mix in the rim of the case.

Sir, if the rimfire is headspaced properly you will not hurt your primer mix. My 2 competition RF rifles are headspaced for Lapua ammo. I'm certainly not a trigger or fire control expert, but I thought that the camming of the bolt lugs and firing spring force determine the amount of force to cock and close the bolt.

 

[butchlambert]

but I thought

I'm glad that you did!

 

[butchlambert]

That is what you said., "but I thought that the"
You know that We Know that we really don't know, But we think we know, if We keep trying we will know.

As you may see by my post. I answered your post #14 before you added the rest of an answer after editing it.. If you will check you edited it a minute after my post #15.
How about your opinions and not gibberish?

 

[butchlambert]

Don't drive your lawn mower into the the Pond then you will Know.

You out of words and sage advise!

 

[butchlambert]

Thank you may you live long and Prosper

Thank you, I have. I wish you the same!

Can you post a link to what Speedy said?

 

[jawjaboy]

Can you post a link to what Speedy said?

Starting at time stamp 21:18 to 23:40 specifically for my trigger question. And up to 31:00 for the fire control tuning. I've already been working on the fire control as well as have a Speedy Shroud ordered.

The back story for my questions is in the 5 years since my last match, even though my rig was said to hammer, I've discovered/learned a number of things from various current resources, I've left points on the loading bench, in load development, and possibly (probably) in the gun tune. I'm trying to rectify those deficiencies.

All this talk about timing triggers, maybe your trigger needs to be in "time out". My Jewells have always worked above my expectations right from the package, I would not let anybody tinker with them for any reason.

That be as it may.

Wouldn't it be somewhat helpful to determine if it was tinkered with? Then a decision could be made whether the tinker, if done, was beneficial or safe? Asking for a friend.

Thanks for the link. There is something I don’t like about a Jewell. I thought he might have been talking about that. He wasn’t.
