I read somewhere that replacement bolt bodies can be bought that already have the bolts bent for use with scopes. Does anybody have a link or site to someone that has these?

Gun Parts Corp, http://www.e-gunparts.com, and Springfield Sporter's in Doe Run, PA, among others, sell altered bolt bodies. However, the rifle will have to be re-head spaced. Since this can be expensive, you might want to do a price comparison of new bolt/head space vs. altering your original bolt handle.
I don't recommend attempting to alter the bolt yourself, unless you have the bolt bending blocks, and the experience, since the bolt is easyly ruined. |

You can allso buy bolt handles that are bent.You cut the old one off and weld the new on one.Very easy to do.

I have 1903 and 1938 model Turkish Mausers, and they are big on the
outside, like an 1898, and have small threaded barels, like a Swede. The book to I like best on sporterizing Mausers is by R.A. Walsh: "Mauser M98 & M96 How to Build Your Favorite Custom Rifle" Wherein he acknowledges that barrels are sold for the 98 and 96 with only the .250 Savage, 6.5mm, 7x57, and 35 Remington going to the small threaded small ring 96. He then goes on to say that despite this timidity of barrel suppliers, the the 96 is OK with 25-06 up to 61,000 psi. The fact that Turks are large ring with small threads, lumps it in with the 96's for pre threaded barrel availability. Buy Walsh's book at Brownell's Stock No. 968-565-120 http://www.brownells.com/Index.html If you buy on line, you should try to qualify for wholesale prices. I told the Brownell's website that I am 'The Clark Magnuson College of Gunsmithing". This makes the book cost $22 and not $32.50. If you call Brownell's on the phone, the girls will suggest you get wholesale, the computer is not as price friendly. We did the bolt bending. Our bent bolts do not interfere with heat treatment on the bolt, and are very strong. However, it looks rough when first completed, and must be finished with a die grinder or Dremel tool. We made a heat sink with buttressing threads for the bolt and put heat paste on the bolt. One guy heats it with the torch, while the other guy hits it with the sledge hammer. R.A.Walsh in the book "Mauser M98 & M96 How to Build Your Favorite Custom Rifle" says that one should only convert Mausers with mismatched serial numbers. The rest should be kept for collecting. He also recommends installing a Timney Trigger with adjustable "pull, travel, and creep". He recommends 2.5 pounds or less for target and varmit rifles, 4 pounds for hunting, and 6 to 8 pounds for dangerous game. Triggers are on available at Midway. Brownell's has Timney Triggers: http://www.brownells.com/Product/index.asp MAUSER 98,HUSQVARNA, BRNO, YUGOSLAV, H&R 300, COMMERCIAL MAUSERS 883-100-298 M98-FN-SP Sportsman Trigger $43.60 $29.07 883-200-298 M98-FN-F Featherweight Trigger w/o Safety $65.25 $43.50 883-500-298 M98-FN-FD Featherweight Deluxe Trigger $79.65 $53.10 I have not bought an after market trigger yet, but rather deferred the problem to the Fred Flintstone school of home gunsmithing : I did a trigger job on a re barreled and scoped 98 Mauser this weekend: 1) an hour to reshape the part of the trigger that cams off the receiver to make the trigger single stage instead of 2 stage [easier to pull now ~ 2.5 pounds] 2) an hour make a horse shoe shaped spacer to sit between the sear and the receiver to reduce the hold off. [creep] 3) an hour to cut a nail to sit inside the trigger spring to reduce the over travel. 4) 10 minutes to find a small spring to sit between the trigger and receiver to pull the trigger back so it will not be floppy with so little take up. I took it to the range and got a .700" 3 shot group. [That is VERY good, for me] To disassemble, put the action in an action wrench and the barrel in a barrel vice. Turn counter clockwise. Both tools are available for about ~$40 each, more at Brownell's. [Some of us make our own] http://www.midwayusa.com/ At $18 delivered, this is my favorite Mauser Scope Mount, it is steel and one piece: http://www.midwayusa.com/online/prod...eItemID=149266 These guys can fit with no grinding on the charging hump [except the 1903 Turk]. I recommend the Wheeler scope mount fixture [unless you have a milling machine to locate the holes] $47 I think that for 6-48 taps, Midway is a good place to buy. $15 For that really hard Swedish steel the tap magic cutting oil helps. http://www.midwayusa.com/online/prod...49+***+666+*** For $20 the two piece steel and $4 for the two piece aluminum are my second favorite: http://www.brownells.com/ I buy the 6-48 screws at Brownell's too. I bought Walsh's book on sporterizing Mausers at Brownell's. The Kuhnhausen book on Mausers sucks. The idea is to get the bolt bent without changing the heat treat [past straw color] at the cocking cam on the bolt body. To this end I put Welder's paste in the bolt body. Also, I put a home made brass buttressing thread heat sink screwed into the bolt body. I have never had the cocking cam get even warm to the touch, let alone straw color. The heat treat change is the only reason for not bending the bolts given in Kuenhausen. He seems to suffer from "Heat Treat Psychosis". Or, as someone else put it, " Keunhausen is like a snipe hunt, at some point you stop following the instructions and realize someone is playing a joke on you." When I comes to Moisin Nagants, I am TIG welding on either bolts made from scratch, bolt blanks from Brownell's, or mostly the original bolt knob with a bolt extender welded between the knob and body. This process seems to heat up the bolt body, but 91/30s are all soft anyway, right? In any case after welding of forging, a bolt will look much better after it is shaped with a die grinder. Clark |

Bolt bending blocks serve as a heat sink and I always used a copper rod (a piece of electrical ground rod turned to the right size) inside the bolt. Never had a problem with the bolt getting too hot. On general principles, I prefer forging down the bolt to welding one on. I never had a welded one come off, but I have seen a number that did. Most were DIY jobs, but one was from a top shop with a good reputation. They fixed it, but the customer traded the rifle.

Unless the customer asks for a custom bolt handle I agree with Jim but I use a combined method for forging the handle. I cut the stub on an angled line that is laid out 3/8" from the bolt body on the top and 1/8" on the bottom. Cut down to about 1/8" from going all the way through. Use heat sink and paste. Heat the "connected" area and bend to angle and sweep desired, then fill the V with weld. This adds a little more length to the handle than merely forging it and you still retain some of the strength from the original root. George

george ,you sent those instructions to me, and cutting as you said was a easy weld and the bolt came out perfect.
I used a aluminum heat sink with that heat paste and a water soaked rag to hold bolt in vice,mig weld one pass, let cool. I was fearfull of ruining heat treatment of bolt,welded till I had a nice round mound to grind and finish file. its better than cutting the handle off completely. |

GO TO THE BROWNELL´S SITE AND BUY THE BOOKS (GUNSMITH KINKS) IT´S VERY WELL EXPLAINED, STEP BY STEP. I´VE DONE IT TWICE WITH EXCELLENT RESULTS, INSTEAD OF REMOVING THE EXCESS WITH A DREMEL DO IT WITH A FILE YOU´LL GET BETTER RESULTS AND ANOTHER TIP IS THAT HEAT TREATMENT THING IS A JOKE BUT THE PROBLEM WITH TOO MUCH HEAT IS THAT IT WILL FORM A FERRITA (CRUD DIFFICULT TO REMOVE)INSIDE THE THREAD AND MAKING IT DIFFICULT TO TURN THE SHROUD ONCE FINISHED. KEEP BLASTING! |
