lock question-update
« on: January 07, 2015, 03:51:56 AM »
Starting on a Hawken build. Just got the parts and was looking and playing with the Lock (L&R). If I cock the lock slowly it will go to full cock without flipping down the fly. It is only caught by a very small amount. If I cock hard and pull way back it works as it should. Should this go to L&R to be adjusted. Thanks Dan

You could do that, but I think it's the general consensus that regular production locks need a going over and some tuning/polishing to wring the best function and durability out of 'em. 



Which translates to, No-take it apart and fix it yerseff.    ;)

Thanks Wade. I would if I was sure what to do. I think the problem is with the fly. New flys are cheap so if I was to try I can't mess too much up. Dan

Dan,

I'm not understanding the problem.  When you cock it slowly, is the sear not engaging the half-cock notch?  Maybe the fly is installed backwards?

No,it goes into half cock fine. When going to full cock the fly is supposed to move to stop the gun from hitting the half cock when fired with a set trigger. It is possible to go to full cock with the fly not moved. The hammer has to be pulled back all the way to get the fly to move as it should. I will take a picture tomorrow Thank You, Dan

The fly is a gravity operated device.  How are you holding the lock while you are doing these observations?  If you're holding it flat, it won't fall.

The first photo shows the lock at full cock (but not fully engaged) and the second show the fly down after pulling the hammer all the way back. Dan

dan,
unless you are very competent with locks, i would send it back. i had this happen on 1 lock and i sent it back and (REDavis) fixed it free of charge. i understand that some locks need a little TLC  but my issue was a casting flaw and a little beyond my skill/experience level. My experience has been that most suppliers will make good on any "major" flaws with no charge/questions.
Polishing/ fine tuning.... well, thats up to us.
best,
kenny

I agree with Kenny. I think you may need a new tumbler and a fly.

It is impossible to give you an absolute answer without observing and feeling the lock operate.   Looking at your photos and given your description of what is happening.  I think a little polishing and reshaping of the bearing surfaces of the fly is in order, but you have to be very careful with that so as to not make the fly too short.   The very best thing to do is have someone experienced in working with locks to take a look.   You could also call L&R and send it back to them to let them sort it out.

 There is a definite wear pattern on the engagement area of the sear and some is also
seen on the half cock position.The fly will kick forward if the sear spring is strong enough
to do it when full cock is engaged.
The lock shown needs an overhaul with properly hardened parts.

Thanks everyone. I think I will just send it back. I can handle some polishing but this requires some experience that I don't have. It would be very dangerous to use as is. A little postage and time is worth it to me. Appreciate the responses. Dan

I chickened out trying to fix myself as I had no idea what to change. I sent back to L&R. They replaced the sear and it now works fine. Dan

I just received a percussion L & R lock with the identical issue. As far as I can see, the fly will only go in one way, so cannot be installed backwards.  IMHO, of course.

This seems to me to be a somewhat dangerous defect. They repaired mine quickly and perfectly. I am suprised that some quality control check did not see this problem. It only takes  maybe 5 seconds to check this. I have to believe some human assembles these locks and should check for this condition. They have to assume that not everyone is as knowlegable and skilled as some on this forum to repair the lock properly. Dan
