Hello to all.

I am in the market for the parts to make a sliding tang safety for an O3 Springfield. If anybody has such and wishes to part with it you can send me a PM email. If I can't find the parts, does anyone have a drawing of these items in order that I could build one. I've never seen a O3 that has been converted to such; I've only seen pictures. I've got a little 18" barreled 7x57 Manlicher (I know I misspelled that word) built on a O3 action that is almost finished, it has been test fired but it isn't too far along to make this addition.. This addition would be the finishing touch that it needs.

Thanks,

Mashburn

That's a wild idea. The only thing you could build would be a trigger blocking safety, not a good idea.

Can't imagine what's wrong with the Buelher safety or an aftermkt trigger with a built in safe.

Harvey Anderson, inventor of Acu-Glas, of Yakima, WA, made a side safety. It was positioned rear to lock the sear and forward to unlock. It was a simple bar between the sear and bottom of the tang. Milled away the side of the tang for detents on the thumb lever. HTH

Wheel Weights,

I don't think they were a trigger blocking safety. If so, I wouldn't take the trouble of building one are installing a pre-manufactured one. The reason that I don't like the commercial triggers with the side thumb safeties is they are a trigger blocking safety also. The only way you can prevent a discharge is to have a safety that pushes the firing pin away from the sear.(Model 70 Winchester-03 Springfield-Mauser and etc.) I have a Bueller on it at the present. Browning A-bolts have a tang safety that blocks the firing pin but upon examination I'm too old to have the patience to do something like that anymore. It will probably keep the Bueller but if I can come up with the sliding tang safety it will have one. I'm trying to build a show peace and I just love to show out with something like this .O3's that I have seen pictured with this modification are beautiful. This one is going to be fancy but is going to be a walk about rifle or probably wind up belonging to my Granddaughter or Grandson.

Thanks for the interest,

Mashburn

Hello Ricin,

Didn't this safety mechanism go on the side. The ones that I've seen in pictures have an extension added to the back of the tang and the sliding safety is in the center of the grip up towards the back of the original tang. Somewhere, I've got a picture of what you are describing, but there is no telling what book it is in. That could be weeks work to find it and then, I might not even have it. If you run across any literature or pictures of the safety you mentioned, please let me know. What ever I come up with, if anything, will disengage the firing pin and sear. I re-read you post and I saw one like that last night, I didn't fully understand what you were saying the first time. I don't really care for that idea but at least it's a start. You can't imagine how good the safety that I'm referring to looks on a custom 03 action.

Thanks for you response and information.

... i see a  problem getting enough " leverage " on a fore-aft tang safety to lift the striker assy ... but how about a long side-swing lever as per the latch bolt on a double barrel shotgun ... 

maybe cam a beveled lock-bolt/plate up into your striker slot ...

Side Swing Safety Springfield.

Alliteration gone wild. ask your kid if that is overkill . ( g ) .

*************

just don't gold-plate the lever, ... like the NRA full-page ads for idiots ...

Hello Ken,

Thanks for your response. Your're mentioning some things that have been running through my mind also ,believe it or not. The leverage issue is the biggest hurdle to clear that has entered my mind so far. I've even thought about the shotgun lever but that wouldn't be too comfortable upon firing, depending where it was located and it sure wouldn't be attractive.   A cam assembly could possibly be a workable solution. Also a swing safety would be the easiest to achieve but I'm going to keep antagonizing my worn out brain and probably settle for my Bueller, but not yet. I wish I could find a 03 so equipped or a working drawing of the system itself would solve the problem. I'm still slowly getting through the old American Rifleman Magazines that I inherited. Maybe I'll find something. I've got a good friend, he is the guy who manufactures the Fenris Wolfe single shot rifles in Red Oak, Oklahoma. When he starts to develop something new he gets construction board, scissors, thumb tacks and glue and starts what I call making paper dolls on top of the work bench. I laugh at him but he usually accomplishes what he has set out to do. So, maybe I'll have to start making paper dolls myself. With all of the projects that I'm trying to finish, I shouldn't even be thinking about such a project.

thanks again,

Mashburn

Ken, it does not lift the sear, it locks the sear so it can not fall. Springfields are like "mousers", lever with a spring on one end. Slide a piece of steel between the one end and tang, sear can not move. It works off the front of the sear, not the rear. So you end up with the first stage of the trigger locked and you never get to the second stage.  Ric

Another possible option is a Win M70 style safety.  Brownells shows one in their catalog.  Requires work on the bolt shroud, but suspect if you can do the work for a tang safety you can probably do this work as well.

If someone wants to try the M70 style safety modification, I have a kit you can have for postage. Remember you have anneal the shroud, do the machining and then reharden. And hope it doesn't warp too much.

Hello Ken and Ricin, 

To make what I'm thinking of, you do lift the striker, you lift it to the back against striker spring pressure, and away from the sear, which is the same thing that a standard O3-Mauser-Model 70 Winchester does. The look of the tang safety is what is fascinating me. I'm a chronic pain person who is up most of the night and this gives me something to mentally wool around in those creative late night hours. The old famous gunsmith, from yesteryear, Roy Dunlap, once said "I've built lots of rifles in my lifetime and it was fun, but now, in my old age, it's a lot more fun to talk about & write about building rifles." I'm about to that point of gunsmithing. I'm not going to give up, I may wind up with a safety that blocks the sear instead of separating it, but I'm going to come up with something.

Ricin, Is the kit that you have a universal kit or is it for a specific action? Thank you guys for your input.

It is for a 1903 Springfield only and ends up being a three position Mod 70.

Hello Ricin,

I definitely want the safety kit.

How much postage required, let me know and I'll send you some money. You will probably laugh but I have another project setting around here that I have never finished that can use that safety. It is a Jap action that I took the jap bolt and a O3 bolt and made one out of them. I did like you would normally do when you are shortening a action but I took the back part of the O3 bolt and mated it with the front half of the jap bolt to get rid of the jap safety. I made my incision back behind the back of the extractor. I have put O3 bolts in jap actions before but the snout of the jap is longer than the snout of the O3. what I mean is, the front of the bolt past the locking lugs is longer on the jap than the O3 bolt. No problem if you are rebarelling, but if someone is using  the existing jap barrel, it won't work. Send me a PM with the postage amount and your address and I will get it right out. If you happen to have a paypal  account I will send it right away. I'm heading back to the shop right now and won't be back in the house for awhile.

Thanks,

Mashburn

Hello to all,

I dealt Ricin out of a swing safety kit for an O3 Springfield. I've decided to do the sensible thing and get this project finished. I don't need another project, that is near finished, laying around here while I scratch my head and work on designing and building a tang sliding safety for a O3. The swing safety will look nice and will be as safe as you can have. Eventually this rifle will go to some of my Grand Kids and I won't have to worry about a trigger blocking safety doing harm to them. Thanks Ricin and Ken, we shared some interesting and good ideas.

Hello Ricin,

I had sent it to you a couple of days ago and again tonight. That is the trouble that I have with PM emails through the forum, they never show up. I'll just give it to you here on the forum so you'll be sure and get it. I don't really care if people see my address BECAUSE I HAVE BITING DOGS AND AUTOMATIC SHOTGUNS.

Hello Ken,

No, I haven't given up on mine. With jacketed bullets it is one of the best shooting rifles I've ever owned. I had shelved the cast bullet project, for a while, but am at it again. I have a bunch of cast, powder coated bullets ready  to load. I have both PB and GC. I believe these will work. If nothing happens I will be shooting them this week. I had my doubts about cast lubed bullets. I'm not a pop gun fan. I like to shoot but I want to be able to hunt with my rifles. It is amazing how many prairie dogs have met their demise from this innocent looking rifle. Mine shoots 20gr. much better than it does 25gr bullets, but on prairie dogs, I lost a lot of killing distance by shooting the 20's so I shot 25's. You probably won't believe this, but with 20gr bullets at 100 yds. I shot some five shot .220" in" groups and those were measured from outside the widest part of the group, not center to center. My barrel is a Sako pull-off. Your not looking at a rimfire barrel are you. Now then you need to do some trading with me for a suitable action.

Thanks for the response,,

Hello Ken,

I started to get on the forum a few hours ago, and then the tornado siren went off, so I headed to the storm cellar. I got out of the storm cellar about an hour ago. That is one good thing about town spreading out towards the country, I have a tornado warning siren. I took a look at the .17 caliber barrel that Green Mountain has, that's a bargain. It's kind of short though.

I've got something that you might be interested in. Years ago, my brother-in-law conned me in to helping him build a .17 like mine. In other words, he wanted me to build him a rifle. It's still in my gunsafe,  waiting to be rescued and finished. it is built on a 591 Remington 5mm action like mine is and is in .17 Cal Mashburn. It is inletted in a varmint style stock(nice job of work). The stock still needs a lot of wood taken off the outside. It has been test fired. The barrel is A Shilen. I bought a unturned blank and turned it to the same size as the receiver with no taper. It hasn't been touched in years. I have several of his projects that I did the work on setting around here. He might possibly sell it to me but he would probably try con me into doing more work other that taking money. If your interested I'll approach him on the subject.

I also have more of the 591 Remington actions laying around here waiting on something to do and also the Falling block works single shot action. I like to trade, I just spend money when I get paid in cash.
