Casting??? Forging??? Machined billet???

Some machining operations have been performed...

Executive paperweight???

Either Swiss 06/29 or Mauser post war?? til...lat'r...GT

Post-war Mauser Parabellum. Looks like a reject that was rescued from the scrap heap after something went wrong during the 59th machining step (give or take).

Nice

Here is one with only 3 steps done:

Interesting pic...I'm guessing the three holes were drilled in the forging (after the rough machining of the flat side surfaces) as a positive locating index for subsequent operations...

I couldn't quite figure out the thin cut in the inside rail area of Roadkill's pic...It doesn't really make any sense...

Neither of these look like how the 'original' Lugers were machined...and that's only my guess from looking at the tool marks on mine...

Hi Rich, ya it does! That's the last, and probably wrong, cut made prior to the toss...

... maybe it was ill fitting in a fixture or clamp of some type... got the boot! ..

They are Mauser's interpretation of the Swiss 06/29 machine steps. Mauser adapted the steps to their own machines. The cut along the receiver rail is the one that went wrong. According to the specifications the top of the frame should have gotten milled out. After that the magazine opening would have been drilled through.

There's a list of steps somewhere???

Shoot!!! I wish I'd known that when I started this...

Yow! you makin' a Borchardt??

Great start, let me know when you're ready for some mag bottoms... Best to you Rich, til...lat'r...GT BTW, did you broach the mag well... ?? inquiring minds want to know!!!

sheepherder · 05-23-2011, 11:22 PM

...Huh???...What???...

Wrong guy...You want Tennbill2...

(Them 6" long end mills are murder)...

G.T. · 05-23-2011, 11:49 PM

Ookee Dokee Rich, thought it was you?? But, anyway, nice job, and I hope you have continued success on your project! Pretty neat, best to you, til...lat'r...GT

You would think with todays alloys and automated casting processes, they could cast a 95% to 98% near net completed P.08 frame.. I really don't see the need for a forged starting blank, unless cheaper?? ...

....Toss up probably, CNC's getting to be old school now... best to all, til...lat'r...GT

nooo Post...you switched the pic on me! I can swear there was a Borchardt frame there when you first posted!
