Check farther down the thread. And you'll see it's all worked out, by following thru.

Went to the Specialist this am. Shoulder X-Rayed. Led to an injection of steriod. Once the drug takes hold, it will most likely help. Hasn't yet. Rotator Cuff injury of some sort. If this does not help ... we'll MRI. Doc is real nice. Takes time to explain. He did one of my carpal tunnel releases a couple of years ago.

Good news 2: Barnes will now be making .308" barrels. No ... I didn't want to be ... but I have this huge shipment of chrome moly tubing .... that's too small for 32 caliber or 8mm, and will require all new tooling ... and all new bullet stuff ... and I might share some of it. Yeah!! .

And, I'm still upright and headed to the shop!

Hello Gary,

Glad you have a good doctor. It is worth a lot to have a professional to take the time to explain why things are the way they are. Continue to wish you good health.

I had chipped tooth a about two months back. It was fixed and had some work done to put a crown on it 3 weeks back. During this time is has hurt a lot. After complaining to dentist they did an x-ray. No nerve trouble visible, yet it hurt. Finally yesterday I got another appointment. They drilled and found it infected. So root canal was started and will be completed after infection is dealt with. It is much better today. I cannot imagine living with pain like you have daily.

It will be interesting to see the results you achieve with a new barrel as you apply all the experience you accumlated over the years!

All the best!

Pedro

Thanks Pedro,

Still here ... saw your post. Hope you get the tooth calmed down. Sorry to hear that. I understand that can be very painful. Hope it passes quickly.

You know ... you get used to regular chronic pains. Sounds silly, but something that frequently hurts, is not as distracting as new pains that arrive. The old regular pains train you to avoid some things, and you expect the responces. New ones keep sneaking up on you.

Be Well,
Gary

OK ... five hours later. Guess you all have a life, or something ... haha.

No - I haven't cooked up some new program. My efforts to secure the tubing sizes I've gotten before, have been frustrating, over the last few years. Manufacturers build to the same "specs.", but the product (while very high quality seamless chrome moly tubing) ... still has an allowable tolerance. That allowable tolerance always messes with my tooling.

This time, I went to extreme efforts to secure a quantity of material, suitable for my needs. That was the "Try this" recent thread. I bought more than I wanted, to assure I'd get greater uniformity ... and that they'd fiddle with my small potatoes orders. The material arrived today, as I returned from my proceedure with my shoulder Doc. Yeah!!! It's here ... ..... unwrap, clean, deburr, get plug gauges .... great ... it's .304 ... instead of .312

The upside is I can make those 308 barrels ya all didn't order. But, I still have to find the materials I need for the 32's I'm short.



Them's the breaks.

Gotta bag it for the night ... shoulder is twice as bad as this morning. Getting a steriod flare I guess. Fruit baskets ... the usual address ...

Gary

Gary :

Sorry to hear about your shoulder, I hope you feel better soon. I see your world famous lucky streak is still going strong. Any chance of returning the tubing? If not, I'm sure they will come in handy. Might make a nice insert for a gray fox?

Karl

Hello Karl,

World Famous .. that's it ... hahah. Just call me "Lucky". haha.

No - the tubing was all cut to ship it. No matter. It will make excellent 308" barrels.

It would have to go inside a 58 caliber ... or 62 smoothy.

About 12 hours later, the meds are starting to help. Thanks. We'll see how tomorrow goes.

Thanks for checking in!

Gary

Gary,

How about one of those fancy reamers you ma..................er, the elves in the tree make? Don't let up on those little slackers, they have nothing to do now that they're snowed in.

Hmmm, .308?

Lon

P.S. Barnes Pneumatic is blocked at my office, something about an aversion to weapons so I can't loiter here. Those people don't know what they are missing.
Interestingly enough they haven't figured out "Yellowforum" but their ability to "sniff" my internet habits keep me on the straight and narrow.
The big guy gets a monthly "click" report.

Gary,

Sorry to hear about the shoulder. I hope it's better today!

I'm not a machinist, so can you help us understand why you can't ream the new stock to .318? I'm just curious.

Scott

Hello Scott,

Sure thing.

Before you rifle, you need a really flawless interior finish to the barrel tube. Has to be of exacting uniform diameter. Must be free of scratches and defects. Quality drawn tubing, will have a far, far better interior surface than you can ream. Most literally has a mirror finish inside. This comes from tooling forced thru the tube, during manufacture.

When reaming, it's the chips that you remove, which are the curse of any decent finish you can create. You have to get the chips out of the hole, and you are producing them with each movement of the reamer. Traditionally, deep hole drills and reamers, have hollow ports thru them, for the purpose of pumping oil or air/oil mix ... under high pressure, while drilling/reaming. I have made reamers like this too. And I've applied high pressure air, with special collars to seal them. You can rotate the drill, or the barrel. The set-up takes a lot of room (which I don't have). Envision full length barrel, and full length reamer - end to end to start ... with collars, holders, lathe head, etc. Gets very long, very quick. The fly in the ointment, is the stray chips. When you are reaming a hole, that's literally three feet deep, and producing a bucket of shavings, a few WILL sneak past any assembly you design. And, they will catch between the reamer and the hole wall, rotate, smear, gall, grind, and scour the whole thing, and highly compromise the interior finish.

You can prepare tooling, to be forced thru the tubing afterwards, to refine the reamed surface. That will give tolerable results. But you cannot repair a scratched up interior, without reaming out those scratches. Then you have no uniform desired diameter. And, I'm picky. And, the operation takes yet another exacting set of tooling, and equipment. It all, also, takes a lot of time. With no gaurantee of success, and a very high probability of a ruined product. So; how does industry do it? Well, for one thing ... they are "Industry". Slightly more expensive equipment. Evidently, with a high enough oil pressure, shielding, and recovery system ... the process works better. A smaller shop might stumble upon a used industrial set-up, and have the space for it. I didn't ... I don't. My shop has an amazing number and variety of tools and tooling. But, I can't have everything known to industry. Just as those shops that do other things, can't offer you the relief carving, engraving, acid etching, anodizing, and a host of other things that come from my shop.

I have done the whole barrel reaming system. And, it's probably been good enough. But, I wasn't happy with it then. The barrels are on the rack still. I might try it again, one day, when I think of a new component to my home shop system, that will produce the results I desire.

Hope it made sense.
Gary

Hello Gary
Hope your shoulder come right soon. Seems like us 55 year olds are slowly falling to bits.....
Cheers
Neil

Hi Neil,

Nah ... this aging thing is a breeze.

Hey ... lookie here. I have guns I need barrels for. It's a rule ... ... guns need barrels. Made this trial tooling yesterday afternoon, evening, and this morning. I've done it a few times before ... Hardened and tempered it. Prepared a blank and pulled a test barrel with the new 4130 chrome moly stock. Etc., etc. Afterwards, I shoved a hard round lead ball thru to get a "slug" of the barrel.





Doesn't just happen by accident. I had to make some choices, make the tooling right, and hit my projections. The heat treat was right (or you hear a big BANG and let half the tool permanently installed half way thru the barrel. The spring back was right. It's clean as a whistle ... right on the money. So there ya go. Another arrow in the quiver. ;?)

Gary

Thanks for the explanation Gary.

It looks to me that you were "destined" to make .308 barrels!

yeah, it takes a while for the steroid to kick in usually.....

dont forget to ice it

Hmmm, Gary, I think you got that right, despite the fact that bits and pieces are falling off you......as with me......

So, there should be some excellent guns with excellent .308 barrels to look forward to. I'm working on winning the lottery...

Cheers

Neil

Hi Bill.

Thanks. Yes - it's kicked in now. Pretty good relief. I'll take it. They used ... either ... Kennalog/Ketterlog .... something that sounded like that. Sorry ... I got my medical degree in the mail. I seem to be a bit more green, and have had to let out my shirt sleeves ... hummm.



Gary

kenalog.......and unfortunately it's not one of the "MLB quality" 'roids

hehe

Man ... you mean I'm "shootin' up" with cheap 'roids?

Well ... he probably took one look at me ... and figured I wasn't worth the good stuff.

yeah, I think you need to renegotiate that multimillion dollar contract......

Just got back from San Diego - biggest orthopedic conference of the year, the AAOS. San Diego is renowned for great weather.....so of course it rained for all 4 days, temps in the 50s ....

of course, compared to our winter here in CT, that is still a major upgrade
because we are supposed to get 6 more inches of snow tonight- yippee

Hi Joebill,

Yeah ... my multi-hundred dollar contract ... is probably some kinda record .... hahah

We all need to go crash at Julio's place. Did you read about his perfect weather yesterday? Made me cry ...



Gary

just the numbers ,,, cant argue with that , close enough.
