For those that surface grind actions, specifically Mausers and the like, if you wouldn't mind showing off your grinding fixtures with a picture, I'd appreciate it.

I am building a fixture for the surface grinder mimicking FALGrunts set-up but would like to see others.

Adam

you could take a look at Mark Stratton's book starting at page 80.

I don't believe i have his book. It's it a published book?

Adam

It doesn't look like I'll get to read it either, as he's not printing any more copies. It's a shame too, I found the website and man alive the cover on the book is just packed with good relevant info.

Adam

Duane,

I agree with you one the good ones. This is more for the actions that need a lot of TLC. Like a certain VZ24 I'm coming in to with TIG all over the SOB.

Adam

Well, I don't know if I would be violating anything if I made you a copy of the relevant pages.

I wouldn't want to brake any copy write laws, but that would be a great help. I put a WTB add in the classifieds but doubt it'll get any play.

ADam

Is the mandrel threaded for the front ring or just fit to the bolt raceway?

Thanks.

Jeremy

Don, that's identical to the one I had planned. A few questions, did you surface the plate and is there a trick to keeping the center in-line to the collet holder?

Adam

No I didn't grind it as my grinder isn't long enough. Sarret makes ground plate but I was too cheap and it is mostly for cosmetic reasons not truing. For lining up just turn a point on a bar and tighten it up. The tailstock just keeps it from flexing under load. I use the same jig in the mill. Used to recontour lots of 1917 enfield and the mill makes faster work of getting it close.

Thank you Don. I too am planning on using this in the mill for items like 33/40 cuts and charger humps. Your mandrel, is it shop made or is it a hardened ground precision rod with bushing? I have both but will probably use the threaded mandrel.

Selected top-end riflesmiths grind even the pristine orig. mauser actions, and for very good reason.
It goes hand-in-hand with the level of precision geometry they produce on the other metal components in the build.

ALL a person has to do is investigate the high-precision/attention to detail, Mr.Echols installs his proprietary mounts
with- and it becomes easy to understand why grinding is done and is deemed necessary.

also,... This is the first custom M98 build i ever kicked off some 20yr ago,
The riflesmith involved would be a fool not to grind the action up to precision spec. to match that of:
the custom precision bases,
trued/re-machined Conetrols,
excellent high precision Rabourn shroud
the custom bottom metal
and to better facilitate the high level of stock inletting.
_ _
the action is squared & sharpened-up allover to match the defined edges & trueness of all the other modern metal parts,
(including barrel reinforce edge & muzzle).as is the stocks exposed edge on the righthand port,also made well defined.
THE rifle is holistically planned and built to compliment itself from tip to toe.

I really dont care that the action no longer says DWM Argentine 1909 ,.. on the side wall.
Its an insignificant small trade-off for what the customer gets in return in the final product.
Now The reality is,
its a top tier build M98 hunting rig, but a step above most ( on par with the superb Echols Classic builds),
since like the Echols, its genuinely of a 'no compromise' modern contemporary build standard.




notice how the trigger actually closely follows the Radius of the inside rear of trigger guard,
rather than just looking like a bent stick in the mud.

the B-handle is not a batch run item , but a 'one-of' full custom creation, which has more trim-elegant dimensions
than one normally sees.....It better compliments the slim proportioned barrel, which is 24"(.515" muzzle )

The ring adjust screws in the bases are smaller dia. than normal,to help make the rifle look more refined.

Hot damn that's nice.

Adam

I bought this one from Ted Blackburn:

I like the Blackburn/Kobe jig. It looks alot like the one we used when I was in school, except the one in school had an expanding mandrel. That jig has some mass and looks like it was built to take wheel clearance into account. That helps shorten up the overall set-up.

The expanding mandrel shows up in the first picture. The pins on the right align the flats on the top of the rear bridge to the correct 30° each side.

That is a nice rig, very simple.

The handle, does it have a limited rotation? I noticed the pins protruding from the right hand side.

Adam

When extended, the pins align the back lever to orient the top flats (30°). It will rotate a full 360°

Ahhhh! Now I see it! The one at school didn't have the limit pins,,, they're a good idea.

That's a really great idea.

Adam

Trax, You may not want to go posting pictures of that all over the net, especially considering the felony destruction of a serial number under federal regulations. It is gorgeous though, thanks for sharing.

Adam, I have Mr.Stratton's book if you would like to peruse through it.
