Paid another visit to our friend 1911 Tuner and brought two of my problem children, a like new full sized Norinco and a Series 80 Combat Commander.
The Norinco had been shot very little but was beginning to beat up the barrel lugs. The slide was a little loose but not bad .
He checked headspace and found it to be excessive and needed another barrel. He had a used Colt barrel that would fix it with a little fitting. So this is what he did.
1--- fitted the barrel
2--- swaged the frame rails
3--- lowered the slide and lapped to the frame
4--- installed o/s FP
5--- reworked trigger
6--- reworked G.S. tang so it didn't hurt the web of your hand.
Now to the Colt
It had not been fired a great deal(less than 2000 rds) and one of the first things he pointed out to me was a crack in the frame. Also the frame was battered very bad by the rear of the recoil spring guide.
Using his files he corrected the frame battering and said shoot it and watch out for more of this. Now for what else he did.
1--- fitted a new recoil spring
2---O/S FPS
3---Kart barrel bushing
4---tweaked several of the magazines for FTF and early slide lock
Both pistols work great now and the failures I had have gone away.
Before the visit, I asked him about bringing a friend along with me and he said O.K.
Tuner impressed him a great deal with his skill and knowledge about 1911s.
He showed him how to detail strip an older 1911 with parts of the pistol and show him how various things can stop the pistol and what caused them.
Then in comes Matt with 2 git-tars and wanted Tuner to pick with him.
Both my friend and I really enjoyed the picking and singing.
Then in comes Kelie and Connie and sat with us and carried on conversation with us. Matt picked music he made up and Kelie sang the words that she made up to go along with Matt's tune.
My friend Mike was very impressed by the whole family and talked about them most of the way home to Georgia.

Thanks for this memorable experience. We appreciate it. Now Johnny, some day, hopefully soon, I'll come for some of your coffee and for playing with the dogs. Sorry, no guns with me, not allowed. I hope you do not mind! The guns and ammo will be on you!!

Howdy Ken! Glad ya'll enjoyed y'selfs. Ever'body likes Travispickin'. (That's Merle Travis...not John Travis.) FOr those who don't know...Travispickin' is a more raw version of Chet Atkins' early fingerstyle, with muted alternating bass lines. Chet took Travis' style...aligned it and refined it...and many people call it his style...but it's just a cleaner version of Merle's.

Oh yeah...Pistols! Almost forgot.

The problems:

First the Colt. The burps were intermittent...which can be maddening to shooter and tweaker.

The impact damage to the frame looked to have been caused by many rounds with a too-light recoil spring. Colt Commanders typically come in with springs that measure in the 14-15 pound range. After several thousand rounds, they get pretty soft. Not all buyers realize that the spring should be changed peroidically, and just shoot the soup out of the guns. Ken bought the gun used, so it ain't his fault. That's likely what caused the crack at the rail/tunnel junction too. A Wolff 16-pound GM spring, trimmed to 24.5 coils set it right.

The bottom of the barrel ramp was flush with the frame ramp, which was a player in the feeding and RTB issues that Ken had with the gun. Surprising that it wasn't worse than he reported. Set the gap and reshaped the barrel ramp. Opened up the breechface guides to .486 inch from .480 and added a little bend to the extractor. Odd thing. The extractor had a mod that I've never seen. The bevel that allows smoother rim pickup was asymmetrical...cut on an angle that made it deeper toward the back. Actually worked well, but gave slightly erratic ejection. I left it alone, since it was working...but it does kick the brass out in a fan-shaped pattern, but without producing any "head shots." I played with an old extractor a little, and decided to just stick with the old method.

I had a Kart bushing left over from an Easy-Fit kit that I used a different bushing with, so I cut it down to length in the lathe and adapted it to his Commander. It required very little fitting to the slide. The second test-firing showed a definite accuracy improvement, and the little Colt ran the falling plates at 25 yards in fine fashion.

Two of his magazines...new Metalforms...were a little too wide at the top, which was letting the rounds nose up as the slide hit the rims, and letting the rounds shift to the left and bumping the slidestop lug...producing occasional premature lock. I set the follower angles to spec and put a little squeeze on'em in a vise to bring'em to spec width. Once in a while, Metalform will throw a curve...but not often.

A little late timing problem with the firing pin plunger release was resolved.
****************************

The Norinco:

Battered lugs caused by insufficient vertical engagement...and .020 inch of endshake! Pistol
went to battery on a NO GO gauge like it was a snap cap. The barrel had to go. Colt barrel
showed just over mid-spec headspace, but was little better on the vertical engagement at .034 inch. (The OEM barrel gave just .030) Hammer and punch time! Brought it down and lightly squeezed the slide to tighten of the sideplay...filed and lapped to fit. I didn't make it "Bullseye Tight" by any stretch...Ken likes to shoot'em hot and hard...but it's much better and very smooth.

Final vertical engagement with the Colt barrel is .045 inch with lugs 1 and 2 taking the brunt.
Pressing on the hood in battery gave no barrel drop...which is a good sign...
He'll be back next year...probably with Kart barrel in hand. :cool: With the frame to slide specs, he can get by nicely with an Easy-Fit barrel. If I know Ken, I'll probably have to retighten the slide a bit.

John...Come on when ya can. Before ya leave, you'll be tired of shootin'.

Man, I'm so close, its a travesty to have no borrowed some of Tuner's time yet....I have one of them Brazilian crunchin-tinkers that I would love to get a once over, how does a guy go about setting that up?

PM me to set up a time that you can come. I PM the directions from whichever direction you'll be comin' in from. Not far from an I-85 exit, though the directions will be a little more complicated since the bridge is out on Briggstown Road, complete with detour...but still not too bad.

I'm retired, so my schedule is flexible.
