Building a Mauser
Match Rifle
- One of the
local outfits is holding "F-Class"
matches, that is 600 yd., prone, any sight, any style of front
rest.
- My brother
purchased, for me, by mistake, 2500 Hornady 75
grain, .224 inch, A-Max bullets.
- I always
thought P.O. Ackley was an interesting guy.
So, I ordered a 26-inch heavy varmit style barrel with SRM threads from E.R. Shaw (their on the
web now!), deep chambered in 22/250 A.I.
While awaiting delivery of the
barrel, I prepared a K.KALE (Turk) action. First, I
cut the knob off the end of an already bent (forged) bolt handle and welded a
threaded extension on the stub.
This is the extension and bolt
body held in a Brownell's Bolt Welding jig. The bolt body is
covered with heat stop (in addition to stopping the flow of heat, it prevents
scaling, to some extent) and has a heat sink threaded into it. Once the
threaded stub was tacked in place, the bolt was transferred to the bending
blocks, NOT for further bending, but because the cast iron blocks are a pretty
good heat sink.
The threads on the extension
are covered with the two nuts at the very top of the photo.
The hand guard extension on the
front of the K.KALE receiver had already been removed, as shown HERE. The inner torque shoulder was lapped
using the lap described HERE.
This shows the shoulder lap in
use, and this:
shows the business end of the
lap. The 400-grit lapping compound is smeared on the face of the lap.
This is the front of the
receiver, the inner torque shoulder, nice and clean, and now true with the
threads and face, is clearly visible.
Next the bolt lugs were lapped,
again using 400 grit compound, and a spring loaded tool (shown HERE).
Using the same threaded bushing
as the shoulder lap, the face of the bolt was lapped:
Here is the bolt face lap doing
its job. Additionally, you can see why the extension was welded to the bolt
handle stub J.
The BIG, black, plastic knob
will provide an easy grip and a lots of leverage !.
The bolt face lap looked like
this, a 1/2-inch brass rod to fit the bushing, with the end turned to 0.480 and
cut square with the rod.
