A while back Fiftydriver posted that he was liking and using the Jim Borden actions also. He's working on an action of his own design now.

IIRC, Home page (Defiance/Phoenix Machines) is making the action to Kirby's spec.

Re: Let it be known

In 13 years of doing this I've never had an action "hit the number" on the thread pitch diameter on the first pass.

-That sounds a little strange so I'll explain:

I use a slant bed CNC turning center for all my barrel work. I use a canned thread cycle called a "G92".

You direct the tool to approach the part, then it starts cutting threads. The "number" according to the Machinery handbook for a 1.0625X18 thread is .995" for the minor diameter.

In all cases (this action being the exception) I have to either bump an offset or write an additional "squeaker" pass to get that silky thread fit that I'm after.

This time I hit it on the first try. Maybe coincidence, I dunno. Don't care either, all I know is its cool when it happens!

Chamber runout was in tenths, .00012" up at the shoulder and .00017" back in the web area. I can live with that I think!

Anyways, I like this receiver. Machine work is very clean, good primary extraction, all the tapped holes look good, the bolt is nice and slick (I think it must be surface hardened, either nitrited, or cased maybe) and the overall presentation is spot on. All the edges are finished and edges broken without being overdone. (rare)

Hats of to Borden. Nice, nice piece.

Chad

Re: Let it be known

Correction on my part:

I received a warm note from Mr. Borden. I'd commented on the threaded holes as being tapped. He politely informed me they are in fact thread milled. I'd wondered as all the blind holes are finish milled with flat bottoms rather than drill pointed.

EVEN BETTER!

Save yer pennies gents and buy one of these buggers, you won't be disappointed.

Cheers,

C
