I got this tip from a Dutch gunsmith.Simple as that, can't believe I have not read about it somwere.
When reaming chambers, he always sent oil in to the muzzle with preassure, which made the chips float out, so one does not have to worry about chips burring the chamber, or to take the reamer out to clean - at least not near as often.
Neat trick, he just filled a gallon jar and put it on a shelf above the lathe, and then a rubber hose down to the muzzle. The height difference gave more than ample preassure.
It works great, but I have not found a good way to fasten the tube to the spinning muzzle.
I could make a - thing - but I have other things to do.
I am sure many of you use this method, do you have any tip for a good device?

Bent:

I use a Duff/Norton Rotary coupler with a gearhead pump high prewsure (30-125 psi) flush system (with Rustlick 255R). If you are going to this trouble why not use a drill pump a small reservoir and a catch pan with a return line. this can be done with about a gallon of pipe threading oil. Don't forget to put a couple of earth magnets in the pan an reservoir. You should also use some cheeze cloth as a filter.

I don't do mine this way but I know others do.

midway used to sell a "chambering spider" that was a rotating and non-rotating part, held together with an O ring... you clamped it to the muzzle and put your hose in...

my solution is FAR more expensive and tons more trouble...

Thanks for the Midway-tip!

I use the one sold by, www.gtrtooling.com
It is expensive for what you get but it works.

James

jeff - did that you have to change anything on the rotating thing for the different twists????

Thanks, neat web-site!

Why would anybody buy a nylon/plastic piece of crap when they could buy a stainless steel rotary coupler with bearings, grease fitting, and can be run straight or 90 degrees. This is a no brainer.

My Duff Norton Rotary coupler is about 5 years old and done over 1,500 barrels. It is still going strong. I am sure it will last the rest of my life. Anyway it can be rebuilt with new bearings.

Longshot..
what did you pay for that stainless thang? more than 60 bucks? which is what I remember the delrin (not exactly junk) spiders closed out on midway for... WOW... 1500 barrels in 5 years? (not being sarcastic) You are averaging 300 barrels a year? Sir, my hat is off to you, and I wholly respect your opinion... You, sir, are a VERY busy barreling guy... I, however, aint a full timer,

jeffe

Longshot, thanks, do you know where I can order one?

Bent:

I ordered mine direct from Duff Norton, but MSC, Grangers, and others have them. I think I paid about $90.00 for mine but I know you can get one from MSC for about $75.00 plus shipping. (I did not know better at the time) I used a home made rotary coupler with gaylord packing for years before I got the Duff Norton Rotary coupler. It is smooth as glass and a great improvement.

Longshot is the fellow who invented the Lambeth-Kiff (or Kiff-Lambeth if you live in Oregon) micrometer adjustable reamer holder.

He is, as my grandma used to say, "one reaming s. o. a. b."

This is possibly heresy to all of the real machinists and gunsmiths, but when I finish getting my lathe set up next week, I am going to get everything straight & true, and then use a flush system, floating reamer holder and the K-L micrometer system.

Longshot:

The rotary coupling looks like the ticket. How are you adapting it to the various barrels? I do a lot of octagon barrels so it would have to seal in the bore. Thanks!

Glenn

Hi Bent
You are welcomed to come dowm to se our way of chambering.

1 old revolving lathe equipped with a rotary joint for oil thru bore, an cheap hydraulic unit 1500 DKR and a rubber sealing in the jaw where you pushes the muzzle before tightening the jaw. the chamberend is supported by a steadyrest.

Capacity about 20 chambers/hour in the same caliber. Repeatability within 0.0004" in depth

Hi Jørgen,
Thanks!
Belive me, next time I am in Danmark, I will most certainly give you a call!

HST:

I made a very elaborate spider with a hollow 60 degree internal cone. I will tell you that I made the biggest mess you have ever seen with coolant. I found keeping ot simple with a 60 degree hollow cone and three hose clamps with heater hose has worked like a champ. I use different sized hose ID for different barrel muzzle ODs. There is a picture on the John708 project thread on 6mmBR website.

As for the Lambeth/Kiff Micrometer Adjustable Reamer Stops it has been a colaborative effort with Dave Kiff and I can't say enough good things about him. Dave is a great professional and I thank him for his patients and help over the last year. Dave runs a great shop.

As for the Name, Lambeth/Kiff Micrometer Adjustable Reamer Stop, if Dave wanted me to call it the Kiff/Lambeth Micrometer Adjustable Reamer Stop I would not hesitate in one minute. It has be a joint venture from the begining we both have a lot of time, effort, and money invested.

Lawndart:

When you get your flush system going and use a floating reamer holder with a Lambeth/Kiff Micrometer Adjustable Reamer Stop You will never look back.

The speed and accuracy will amaze you.

It use to take me a half day to do a barrel from start to finish. Rarely does it take more than 2 hours now. I will admit I have the tooling , set up, and process down to an art. As you know working in the headstock is much more rigid and allows for better cutting speeds too. There are many others over the years who have inspired my set up. I will give Greg Tannel credit he has moved the ball into a new court. Butch Lambert, Mike Bryant, Micky Coleman, Jackie Schmitt have all been shakers and movers on the different gunsmithing sites. One common thread has been Dave Kiff. Let me say Dave Manson is a great guy who makes quality tooling and gives good advice too. It is interesting both Daves got their start with Clymer. Clymer and JGS make quality tooling, but Dave Kiff has become the guru of chamber reamers.


If you have any questions I will be glad to speed up your learning curve. If there is a mistake out there I have made it.

Good Luck
Longshot

Thanks for the kind offer Longshot,

When I tire of enjoying my screw-ups, I'll certainly cry out for help (probably over on BRC).

Dave Kiff has been great with taking care of my reamer needs for the last five years. He has gently steered me away from some less than stellar ideas. My comments above were very much tongue-in-cheek.

OT, Dave has the drawing for the "6.5 lawndart". Sorry about the name, but I had to hurry before Rick Jamison patented the design . Anyway it is a tighter, but still no turn version of the Grendel. Just a thought if someone wants that in a bolt gun.

I'll stop by the next time I am back in N.C.

Thanks,
LD
