  1. The Walsh book is the only way for me for feed lips on VZ24 to magnum conversion. I would have never figured it out.
  2. See that notch in donmarkey's wrench? You can use a wrench without it, but it scuffs up the receivers and binds the bolts. It took me years to figure out why I needed that notch. The bolts, the contact to the top of the receiver, and the contact to the bottom of the receiver, must all be in the same plane, or there is bind.
  3. Kuhnhausen is like George Lucas. Star Wars 1977 was great. But Star Wars 1999 was not even up to TV standards. "The Colt Double Action Revolvers: A Shop Manual" 1990 , is THE book on the topic. But "The Mauser M91 through M98 Bolt Actions. A Shop Manual" 1990 is the worst lack of editing I have ever seen.
  4. I have measured the accuracy of 98 Mausers with 10 foot pounds of barrel tightening torque, and with hundreds of foot pounds of torque. They shoot the same. Most people put barrels in rifle receivers with 50 to 100 foot pounds of torque, thinking that is enough so they will not shoot loose. The VZ24 receiver has an inner C ring that acts like a lock washer. That puts the threads in compression. The Rem700 rests on the shoulder, and has the barrel threads in tension. Remington put glue on those threads, and that means they must have had some come lose. It took me 540 foot pounds to get this barrel off, and 200 foot pounds to get it back to the marks in my Mosin Nagant videoL
  5. Thanks for posting that. I have 14 MNs and 9 of those are in states of modification. With 4 of the Tennessee Guns bull barrels, we may make some stock from scratch. You are an inspiration.
  6. I have converted to 45/70 and I have converted to 30-30. Someone is offering to rent me the chamber and form dies to do 6.5x54R,
  7. I made this sketch to put above my lathe when I was working on my Rem700. I have one Rem700, and ~ 100 Mausers, so I know very little about Rem700s, but I have a few Rem700 take off barrels I can measure. They are not all the same.
  8. That brings back good memories. I got a light varmint taper Lothar Walther 257 barrel through Brownells in 2002 and made a 257 Roberts Ackley Improved on a VZ24 action. I had tried for years to get a 1" group. That rifle was a break through for me. That rifle averages 1.2" 5 shot groups at 100 yards with 115 gr bullets. That rifle averages 1" 5 shot groups at 100 yards with 100 gr bullets. That rifle averages 0.8" 5 shot groups at 100 yards with 72 gr bullets, but has shot a .45" group.
  9. http://cdcotools.com/ I have bought expensive drills in the past, but now I just buy a 115 piece set from CDCO for $35. I have had one drill that was no good and two more that got dull fast, but other than that, I use them full time with no problems.
  10. The EGW mount is $40 and very high quality. Here I have posed it between a La Coruna commercial Mauser action and a La Coruna military action. Do not move the mount back on the military so that the two screw holes are in the rear. That puts the front holes into that that should not be drilled.
  11. Roger, I try to make the inner C ring touch the breech face when the shoulder touches the large ring. If there is an error of ~ .001", I make it so the breech touches the inner C ring first. That is because the inner C ring in cantilevered and has a little compliance, while the large ring, breech, and shoulder are stiff. Ken, The stock is ~ $200 wholesale and compares with a $400 McMillan light rifle stock, the High Tech Specialties [bansner] stock is not finished, painted, or perfectly inletted. It depends on your situation, if that is worth it or not. I put spray paint on it, and went hunting later that month with it. I think it should really be an epoxy paint that is harder to wear off. I cut off the stock butt in the power miter saw as per usual with a wood stock. I had to screw and epoxy in a piece of wood into the hollow butt, so I had something to screw the limbsaver recoil pad into. dogz, The full trigger job on a Mauser fixes the: 1) force 2) take up 3) over travel I find for big game hunting rifles, only the force is important. To do that I: 1) Grind some off the hump, to loose the second stage of the two stage stock military Mauser trigger. In the pic below are two triggers side by side, with the hump ground off one. 2) The trigger spring is changed. The pic has also been milled, Silver Soldered, drilled, and tapped for a take up adjustment. I would not do that to a 9 pound 7mmMag.

I built two other 7mmMags at the same time with scrap parts, as practice, as I went along. The Rem700 take off barrel on a 1908 Braz Mauser has very little time or money into it, and shoots just as well. That was not per my plan.
  13. I built one. Single shot. Typical 91/30 extractor relief extra work, but it is less work than the breech work on a Sav99.
  14. I have been helping the guy: Weld bolt handle Fit stock pillar bed and glass bed Pull the barrel, drill and tap, and add scope mount
  15. There are millions of guys with guns around the world, but the ones near Seattle get on the internet more.
  16. I recognize the phone number. That guy, Drew, just bought a shaper from me. It took quite a while of looking to see that he was not just re selling mine at a loss. He upgraded. I had the shaper for 5 years and never used it.
  17. I have worked on over 100 Mauser receivers and never had anything heat treated. I can hardly express how contemptuous I am of Jerry Kuhnhausen's book on Mausers discussion or re heat treating. For some yay-hoo on the internet to say that stuff is no big deal. Plenty believe in UFOs and big foot. But that is a published and widely sold book. There is just no excuse for that.

    Used Lathe

    You might be able to commute to work in a 1967 Cadillac if it has 20k miles and is in mint condition. But by the time Boeing and another company got done with my 1967 Clausing, it was ready to be restored by someone who was a fanatic. Last month I got a new Chinese lathe of the same size, 12x36, but with DRO, and now I am getting things done. Last week I put a used Krieger barrel on a used Rem700 and chambered it in 6mmBR. The rear of the chamber was with in 0.00075" when I was done. The second group out of that rifle was 0.55" 5 shots at 100 yards, with a 10X scope. I think I can do twice as well with a 25X scope that lets me see the target. What does it all mean? I have screwed around with 3 marginal lathes over the last 10 years, and now I have one that gets the job done.
  19. I was working on a 91/59 for someone else today. He got a Boyd's stock to replace the tupperware stock. I was pillar bedding it and the rear action screw was bottoming out in the threads in the trigger guard. I don't have a 1/4-32 die, so I cut a .060" long bushing from .375" O.D., .305" I.D. steel tubing. That bushing acts like a washer, but pressed into the trigger guard like a bushing, and will not get lost.
  20. Savage 110 barrels headspace adjust with a nut. There is a Savage forum where a guy sells allot of pre fit barrels from both Shilen and Mcgowen. There have been comparisons between the two. I don't own any Mcgowen, but I do own Shilen. Shilen chrome moly can be crappy, but Shilen stainless select match is as good as it gets. The comparison between Shilen and Mcgowen on that site is that they are both premium barrels, but Shilen stay clean longer and clean up faster. They are both about $300 and the Shilens are the select match. The thread is 17 pages long and has the title " "In Stock" Savage Pre-Fits - Shilen and McGowen Barrels - Updated 4/13/09 " I got a 19" long Shilen select match 6mmPPC benchrest take off barrel for $75 off Ebay back when Ebay sold barrels. I reamed it out to 6mmBR and put it on a $175 1917 Savage 99 250 Savage take down. I drilled and tapped for scope. I put on a 6.5x20x50 VXIII varmint scope. In two trips to the range it has averaged 0.2moa, with the terrible 8 pound trigger. The Shilen select match barrel is so good, if the Mcgowen barrels are close, it would be better than I could ever need.
  21. When I was 10 years old in 1961, another 10 year old, Norman, told me his father was reaming out a Springfield to 300 Win Mag and bending the bolt on a Mauser. By 2001, I was reaming 300 Win Mag chambers and bending bolts on Mausers. I know what Norman was talking about now.
  22. That Oak table looks like some quarter sawn furniture my grandparents got in the 1920s and 1930s. An elegant cut of wood for a more civilized age.
  23. I milled out a mighty mag base so it would fit a dial indicator for measuring chamber reaming depth from the tail stock. Someone pointed out that all I needed to do was take the back off the dial indicator and turn it 90 degrees.
  24. I was hunting with a highly modified pre 64 M70 and our host was hunting with a Weatherby. He has a log cabin in an area with lots of deer, antelope, elk, sage grouse, and ducks. We shot em all or shot at em, and wooped it up at his house. At the end of the 7 week season, with two days left in the season, we all left, and the host went out by himself and shot one more deer, but with his old 91/30. He first bought a 91/30 40 years ago in Sears for $7. He shot jack rabbits with it as a child. This year he shot a mule doe in the head at 200 yards, way out in the sage brush by himself.
