screw?

[DANNY-L]

Can someone tell me what the name is for the screw below the hammer so I can order one,I was cleanining my father in laws cva frontier and I sat that little bugger down someplace safe so I wouldn't loose it and guess what. Well wherever it is it's still safe. Thanks

i'm guessin' you mean the little clean-out screw in the drum. if you can figger out the thread size you can get a set screw from lowes or an auto parts store. luck to ya and have a good'en friend, bubba.

Danny, I'm not sure what you mean by the screw "below the hammer".  But if you're talking about the clean out screw that goes into the end of the drum (see picture) it's best to replace it with a set screw from your local hardware store. 
 
I don't know the thread size, but it's likely to be a metric.  Take the barrel to the store with you and find one that fits.  Buy two or three for a few cents each, and an Allen wrench to fit them.

If indeed that is the screw in question, I would not recommend a set screw. The screw needs an enlarged head so that it can be tightened down to a positive stop. A headless set screw must either be left loose or tightened in against the side of the nipple which will damage the nipple threads. A round head screw will probably need to be "custom fitted", that is it will need to be shortened to a length that when threaded in tight will just clear touching the nipple. It's a five minute job but an important one.
 I have often put something in a "safe place" only to never again find the "place", not just little things like screws, I've been searching a year now for my package tape dispenser. I remember finding the perfect place to keep it but can't find that place.

My traditions came with a brass clean out screw that went away many years ago.  I re-tapped the hole for an 8-32 socket head cap screw, then fitted the cap screw.  To make the repair less obvious I filed the head down and left the allen wrench recess kinda shallow.


Head to the local hardware store and pick up a few screws that are "about right" (metric and standard) and get ya some cold blue or something to color the screw head.

Coyotejoe, I have set screws on two TC Hawkens and three Renegades that each have had many hundreds of shots fired with nary a bit of problem.  Also, I remove the screws for cleaning after each shoot.  As a matter of fact, Green Mountain replacement barrels come with a set screw installed in the bolster.  However, if you feel you must have a head, a button head cap screw will provide one and still be better than a slot head.

Yes that is the screw now missing. I didn't realize you could use any screw as long as it threads the same,I was kinda thinking it was beveled. So off to the store we go and if I find one I'll just cut it to length so as not to interfer with the works. After all that 'll probably find the other one. Thanks all

my hawken, 2 renegades, buckeye hunter, and all 4 of my green mountain barrels have set screws in them and they don't hit the nipples. for what it's worth and have a good'en, bubba.

And none of those are CVA drum and nipple guns. If you run a set screw into a CVA drum it will not stop until it tightens against the nipple.

[Semisane]

Not a problem so long as you don't crank it down gorilla tight against the nipple threads and back it out a bit before removing the nipple.

My buddy is always losing those clean out screws so he but a 1/2 dozen from the hardware store to have on hand.

[tacklebury]

I put a little breech plug grease on it which helps it back out easier for cleaning and yet doesn't seem to work its way out on its own.  hehe

A hacksaw and some files, along with a little clamp-on vise will allow you to rework stuff from the hardware store to fix just about anything your gun needs. But the ultimate kitchen table tool is a Dremel. I use mine all the time to make parts from scratch. Many years ago I saw a guy build a working SMG reciever with one. Nuff said.

Unless you don't run it all the way down.

In which case it is loose.

Find a set screw that is .080 longer than necessary.
remove nipple from drum screw set screw in until it just misses the nipple leave the allen wrench in screw.
Take a hammer and punch and upset the screw working your way around it. Leaving the wrench in it will cause the screw to upset to the outside and keep the hole open for the wrench to fit. Snug the screw up and check the clearance for your nipple if it's to close remove screw and file the tapered end down until it clears.

+1 a cold chisel would also work, tap just hard enough to peen the threads
