I was able to manually pull the cocking piece back and then turn and remove the bolt. Closed the bolt, took off the safety, pulled the trigger. Out of curiousity I put the K98 FP/cocking piece in my M48. The 2 Yugos are identical in size, shape, length. Now you made me curious, so I had to go look. Round the firing pin end slightly to help prevent puncturing the primer.I think that firing pin is for ther K98 mausers which are standard length.The Yugo family of Mausers are intermediate length actions.I tried a K98 bolt and it is about 3/8" to long.If i am wrong about the $19.00 firing pin on the website above,then you sir are the man, becuse I have looked for a firing pin for almost a year for my Yugo M48 and have only found two and they both went for over $60.00 on ebay. Here is what the oxide layers look like, straw correlates roughly to 400-450 degrees.Īfter this, begin finish grinding to shape but leave slightly long. (metallurgy)#/media/File%3ATempering_standards_used_in_blacksmithing.JPG If you have a toaster or regular oven that goes up to 450 that would work, let pre-heat and leave in for about 45 minutes or until straw colored. This tempers (partially anneals) the firing pin so it does not shatter when it hits a primer. Make sure the center gets a little more torch heat than the ends and the ends will heat up. Heat the firing pin, starting at the middle and moving the torch back and forth, until the metal turns a straw color. I like to use old motor oil.Īnnealing - straw refers to the oxide layer color - that is why you have to clean up the steel to bare metal. Heat to non-magnetic (dull red hot) and quench in oil to harden the drill rod. Leave all dimensions oversized to allow for final grining and polishing. Help me obi-gun kenobi, you are my only hope.ĭrill bit is now fully anealed (soft) to allow rough shaping quickly. A yugo mauser pin and cocking piece will work but they are damn near as hard to find. It seems the Mexican mauser uses a different firing pin than all other mausers. My other preferred action was to buy a new first pin but they are rarer than hens teeth. I know the proper way to do this is to use a proper gun smith but the nearest one is too far away.
I did experiment with some drill bits and oil vs water vs air quenching and found that the oil quenched bit bent the easiest although it was cold oil and not ATF so the results may be so much junk.Īll this done I’m going to flux the new pin and then melt silver solder into the hole and onto the new pin before inserting it and letting the whole mess cool. Do I get it just discoloured? Or do I need to get it just below red hot? Again I’m thinking I need to heat it up but again not hot enough to pull the temper out of it all the way. I’m thinking I need to heat it up but not red hot and then let it cool naturally?Īfter I drill my hole using a drill press, time, and loads of oil, I’ve been reading that the drill bit shank may be too hard and shatter when used as a firing pin. Now I think I will need to soften up the end of my firing pin body before I will be able to drill into it at all. I’ve done a lot of reading about quenching and tempering steel but I would like to bounce off a few of you guys to make sure that I understand correctly what to do. I am using a 5/64 drill bit shank as my new pin. I don’t have a lathe unfortunately so I will be slowly grinding the end down to avoid pulling the temper out. Mill down the end until it’s big enough to drill a hole the size of the pin end into, make a new pin end, silver solder in place. I don’t have a smith closer than 1.5hr drive so I’m looking at doing the repair myself. It’s the last 1/8 or so that snapped off.
So I picked up a model 1910 Mexican mauser the other day and found out the firing pin was broken. r/guns /r/NFA /r/Gunsforsale /r/GunPorn /r/3gun /r/Bladesmith /r/DIYGuns /r/longrange /r/CompetitionShooting /r/ClayBusters /r/guncleaning r/gunnitrust
Be aware of your target and what lies beyond.Keep your finger straight and off the trigger until you are ready to fire.Never point a firearm at anything you do not intend to shoot.Treat every firearm as if it were loaded.This sub is to help spread knowledge, please act like it.
