View Full Version : Need Some Gun Help

This weekend I went to the big gun show in Fort Worth with some friends, in order to help one of them find a quality AR-15 for a reasonable price, and help him pick out the proper accessories and upgrades he wanted. While I was there, I found myself drawn to a very humble and worn-looking used shotgun that was for sale. It wasn't pretty, it wasn't fancy or a famous name or anything like that. It could have been Dad's Old Shotgun (TM), really, but for some reason I really liked it, and I bought it for pretty cheap.

So, now I'm the proud owner of a Savage Arms 755A 12-gauge automatic shotgun, from 1959. Yes, it's basically just a copy of the Browning A5, with the same clusterfuck of insane internals and hidden release pins, but I like it.

Now, being a used gun, and well-worn, I knew that it would require some work, so when I got home I decided to play gunsmith and I took it all apart for a deep, thorough and much needed cleaning. This is where I encountered my problem, and no, it's not putting it back together. I got that part perfectly, thank you.

See, whoever owned it before me wasn't really keen on maintenance (hence it being absolutely filthy), and it looks like they used regular taper-headed mechanic's screwdrivers to work on it instead of the proper blunt-headed gunsmith's screwdrivers, and in doing so, they've snapped off half the head on several finishing screws. I was able to take them out (with a lot of careful work), but there's no way I'm putting a broken screw back into a gun, I need new ones. And, that's my problem. I'm not a great gunsmith, I don't have a wealth of gun knowledge, so I don't even know what these screws are officially called. I know they're mainly for finishing, and to keep other, larger screws from turning. My own research has come up blank, so I'm asking for some help. If anyone can identify what these screws are called, and where I could find some, that would be fantastic.

Here is a shot of several of the missing locations. The one on the left, there, isn't actually necessary, since it doesn't actually hold anything, and is just there for looks. In the middle we see one of the screws I was able to save, and how it locks a larger screw in place to keep it from turning. The two on the right need screws for that same reason.

On the breach side, only the useless vanity screw is missing, but I want it there for the sake of completion.

Here is the best shot I could get of the screws themselves. They are completely flat-headed and terminate in a blunt post.

If you know the name for these screws, and have any idea where I could find some (local gunsmiths seem to not have any, right now), I'd be very grateful. Also, if you have any tips for cleaning off that surface rust without destroying the patina of the metal, I'd love to hear that, too.

Thanks!

Have you tried http://www.gunpartscorp.com/ ?

I have, but once I realized I didn't actually know what these screws are called, I was brought to an abrupt halt, unfortunately. Hence this thread.

Have you tried sonics on the rust? They're usually pretty good for that. If there's any patina damage, it's not tricky to re-blue

I didn't even know ultrasonics were a thing that could be used for cleaning something like that! I may have to look into that, depending on the cost.

Some smiths have sonics, and if not you can sometimes take that to a jewelry repair place and have it done for a pittance. You can buy small sonic basins for less than $100 but its up to how serious you are with gunsmithing.

Sourcing screws for guns I am kind of shit at, but have you looked at a massive parts retailer like McMaster-Carr?

Like I told Morg, my real problem here is that I don't know what those screws are called. I've found lots of listings for screws that fit this gun, but without knowing which one is which, I'd be picking blind, and probably get the wrong ones.

As far as getting it cleaned, in a sonic bath, I'd have to find somewhere to take it. I'm presuming I'd have to fully break it down for such cleaning, correct?

Yeah you'd want to detail strip. Jewelry basins are pretty small. Larger stuff exists for the subassemblies, but those are harder to find. I kind of miss having shit like this around when I worked for a surgical instrument repair company.

Those are generally referred to as capture screws. Numrich seems to call them locking screws.

This is what you need. http://www.gunpartscorp.com/Products/54860F.htm

Yay! Thank you, The Boy! That's exactly what they look like. Problem solved!

You're welcome. I love old guns. Lets see some pics of the whole thing.

Well, this is it before I broke it down and cleaned it. Once I get the new screws in, I'll take new pictures of it post-cleaning.

Promised a shot of it after it was all cleaned up. Thanks to Charley, I applied linseed oil to the wood, and it looks and feels fantastic, now. Still waiting on the screws to arrive, but here it is at 98% done.

Amazing as it looks all cleaned up, the second photo is inferior because it doesn't have Guy Garner sitting casually on a car. ;)

Seriously though, that's an awesome looking gun. Are you planning on using it for display only, or do you have practical use in mind?

I bought it so I could go shoot things with it. It's vastly cheaper to run this than my handgun, and I can have more fun over a longer time with less rounds shooting clays than I can unloading clips into paper targets.

Depending on how much I like it, I might even have it stripped down to bare metal and re-blued to this same finish, but even. It's clear this gun has suffered at the hands of its former owners, and the bluing is patchy at best, right now.

God I love linseed applied to old wood. It's just perfect.

And, the new toy I picked up, today: 1920 Lithgow Mk III infantry rifle from Australia, which is basically the same thing as a Lee-Enfield 303. Maybe I paid a little too much, but I really like it.
