wedge capture?

[kingsax26]

I recall a conversation somewhere in the past...about capturing wedge pins so they dont fall out? My lyam GPR keeps dropping the wedges when I shoot ....I have already lightly shaped the tenons ...and one seperated from the barrel...What /how do i do this ...capturing thing?

 

[Zonie]

The captured wedges I'm familiar with are slotted.

After they are installed in the stock a pin that passes thru the slot is installed.

This can be tricky to do because there isn't much wood in the area.

I suggest that you bend your wedges just a bit more so they don't loosen when the gun is fired and leave the captured wedges idea alone for right now.

Like Zonie said just bend it abit. You can lay the pin on a solid object and give it a light tap with a hammer. That will bend it enough to fit tight. Light taps and if the first doesn't work just give it another until you get it where you want it.

I never been a fan of bending wedge keys. Fix the tennon instead, like this;

 

[Vaino]

All the wedges {keys} on my rifles are "captured" and the pin is easily removed. A 1/16" wide slot centered in the wedge width is made w/ the bulk of the mat'l taken out w/ a jeweler's saw and then filed smooth. The .050 dia. pin is cut from a large paper clip. The pin can be inletted under the screw retained escutcheon or a slightly oversize hole is drilled down from the oblique flat of the bbl inlet if the escutcheon is permanently pinned. In either case, the slot is long enough for the head to hit home and the lead end to clear the bbl lug when retracted. Easy enough job and no lost wedges. That's why my wedges aren't fit that tight and are easily retracted w/ my fingernails.....Fred

I'd recommend bending the wedges rather than the tenons, especially if the tenons are soldered to the barrel.I recently purchased a Sharon Hawken kit gun where the builder had bent the tenons and they both have come off when fired.

well when I read the intructions on my lyman rifle kit t hey said to lightly tap the tennon..i did and this is what happened (i might have tapped a bit too hard )...now i ahve to get it fixed ....but i guess I will try bending the keys a little to make em tight

 

[Ed Wingenroth]

STOP !!! Beating on the metal part's of your Rifle !!! It looks like you've got one side already lifted up...

Slowly, file the contacting surface down until it fit's !!!

Ed....

 

[kingsax26]

thats my trouble ......thats exactly what the instructions int he LYMAN manual say to do ...this is the result

 

[RADeO]

Byron, after you get your tenon problem solved and your wedges fitting properly, check out this link for some pictures of a captured wedge. It is an easy modification to do and you will like the result,

Instead if hitting the tennon directly, I have alwasy used a 3/4 socket extension laid it perpendicular on the tennon and tapped on the socket extension to make the bend for my Lymans. Also looking at the picture you posted it looks like the tennon was not completely soldered down as it should have been. You might want to call Lyman and talk to them. DANNY

and tapped on

I think the "tap" part is the key word here.
Those things are pretty soft metal, and it don't take much.
As Paul V would have said,
"leave the Gorilla in it's cage"

 

[kingsax26]

my plan was to just take it and get it brazed back on...or to solder with some metal working solder i have at the house...i re pounded the tenon so it is flat with the barrel again...but i hasn't re attached it..i am kinda disappointed in lyman on this one

 

[DOUBLEDEUCE 1]

I would recommend you look at Acorn Mush's link. I have seen this on his rifle and it is slick. Just like Flehto says also... great idea. :thumbsup:

 

[kingsax26]

saw it ..loved it ....gonna do it ...umm just as soon as i can find time ...

 

[Rifleman1776]

Lotsa fuss and bother for a non-issue. Long-long time ago I had a similar problem with my TC. I simply laid three small strips (about 1" long) of thin leather in the bottom of the barrel channel. Enough pressure was exerted to keep keys in place. And, I swear, it improved consistency in the accuracy department. Might need to replace the leather periodically. Mine has been there more than 45 years. I'll wait until it hits the half-century mark. :wink: :rotf:

 

[Misfit-45]

My Lyman had the same problem and I TAPPED the tenon. I wondered if it was enough. I couldn't tell the difference by looking. Put everything back together and it was perfect. Just enough tension to "feel right" when I tapped in the wedge.
Looking at the picture, I don't think you could get the wedge to fit through both the stock and barrel as much as it was HAMMERED. :wink:

PS.
I love the leather idea.

+1 with Flehto :thumbsup:. I place my capture pin under the escutcheon plate - no drilling of the stock and wedge can be removed with ease when necessary. You will need to adjust the slot in the wedge so that the wedge will clear the tenon on the barrel, very simple :wink:

Obviously, you smote it mightily. You need to learn how to TAP when doing this kind of thing. You tap and try, tap and try, tap and try until you have it where you want it. A mighty smite from Thor's hammer results in what you have there in your picture. Oh well. it is reparable and we all make mistakes. As long as you learn from your mistakes, all is well. Go forth and sin no more :haha:
