Timing an action

[bmccarron]

This is a term that I am not familiar with. Could someone explain what and why it is done, or point me in the correct direction? TIA

Any time you have a mechanical process and/or multiple mechanical process there are important interactions of different components of the process. Different parts of bolts and actions need to be in specific locations at specific times during the process. iE: closing/Battery/primary extraction/opening.
Can''t explain it any clearer. Follows the basic principles of mechanical engineering.

Old thread but yet another possible edge for your bag gun. Plus a little plug for Alex"Joe Dirt" Wheeler in his new business. The pretty red one is mine!

See if this takes you there... I'm not to swift when it comes to this crap. If centerfire rifles came with onboard computers, I would find another hobby.

This link says you have to log in, if that is the case I guess I will never know.

Worked for me. It will only work if you have a facebook account.

Don't have anything to do with those social gossip services. Can't access any of those links.

What Alex Wheeler business?

A properly timed action will make the bolt easier to work, especially extraction. An out of time action will make you fight it all the way.

Action timing. Alex had posted a YouTube link but has since removed the post.
10-4 on the gossip services.]

Heres a video showing the difference between an action with the ignition timed vs a stock action. This is not the same as extraction or bolt handle timing.

Excellent demonstration. Anything is possible, but you have to pay to play.

 

[CaptainMal]

Now I know I'm stupid Alex. Watched the video and could not tell which was the "timed" one. Give me a hint. Right )with scope) or left?

Oh - Alex - PM on yesterday's shoot.

 

[Alex Wheeler]

One left one is timed. Watch the smoothness of the bolt manipulation.

 

[CaptainMal]

Thanks for the reply. Thought the one that sounded "firm" on the right was good. You can hear the difference easily. Just did not know which was desirable.

Now going to play with some of mine and listen and feel.

I am probably not the only one dumb enough to not know. At least I hope there is solace in numbers.

*** My Stolle Panda feels like the one on the right sounds. There's a soft movement, then a physical stop. Then it closes smoothly. You do hear and feel the double and distinct crisp movement.

Your Panda needs work...

For the right one, is the mis-manner because of where the trigger sear picks up the cocking piece(too early)?
It seems like the lugs are continuing the cocking(cock on close).

Yes, that is the way almost every action is setup. It is easier to manufacture as the ramp and trigger position dont have to be exact.

 

[BoydAllen]

Listen to the difference. There is a click on the right one that is the cocking piece falling to the sear as it comes off of the top of the bolt's cocking cam. You do not hear that on the left because the trigger picks up the cocking piece earlier, and the fall is so small that you do not hear it, or it is right on time, or a little early but not too much. If it is very early bolt effort will be increased because the lugs will have to climb part of the closing cams against the force of the striker spring. You won't notice a little of this when operating a bolt quickly, but after a point you will.
