Outside Neck Chamfering

[Walt K]

I've recently taken up shooting Service Rifle.
And of course all the reloading that comes with it.
My problem is that I can not get a good outside
neck chamfer without a burr. I believe my tools are good
and sharp. Short of buying a Giraund or a Gracey does
anyone have any suggestions?

Re: Outside Neck Chamfering

I use an old Wilson handheld tool and do not get burs. Do not stop abruptly, just withdraw as you rotate the tool and it will feather it away, no bur.

Re: Outside Neck Chamfering

What are you trimming with?

I use an RCBS Trimmer, lather type, with the 3-Way cutter that cuts the neck for thickness, chamfers the case mouth, and also de-burrs, all the same time. I've replaced the regular cutter with a carbide cutter. May not be as "sexy" as a giraud but a lot less expensive and I don't mind turning the "crank" by hand.

I have the major brand name (Redding, RCBS) tools. I'd
like to chamfer under power not hand tools. Too much trouble
(slow)to do by hand.

Re: Outside Neck Chamfering

before I bought my garaud I had a RCBS prep center I used. it had a couple diffrent stations on there I had a chamfer, deburr and a primer pocket uniformer on there, it worked fine for me with out any burrs.

Thanks for the replies. I'll keep plugging along trying different tools and techniques.

After chamfering the out side i tilt the tool about 30 degrees and do it again litely to remove that edge your feeling .Arnie

Re: Outside Neck Chamfering

I have to apologize to the members for being a dummy.
Putting my RCBS mutli station tool aside, I placed a Wilson outside chamfering tool( with center shaft) into a Sinclair holder and chucked the whole thing into a small drill press running at low speed and it works like a champ. Next time I'll think it over first a whole bunch longer and not bother people.

It's not rocket science.

If you can't get a nice bevel on the outside edge of your cases, you're either a) doing something wrong, or b) your particular tool sucks.

Re: Outside Neck Chamfering

i had a problem recently with a bad cutter (brand new lee case cutter with the wood ball on it) leaving a nasty burr on my 308 brass.

i tried several chamfer/debur tools only to try a different (non ball) cutter i had and the problem disappeared. Replaced the offending case cutter and no longer have the burr problem.

the bad cutter had a lot of chatter while in use... my good cutter did not chatter at all while cutting the brass. this may be a sign to check for with your case trimming tool.

all along i was chasing the debur/chamfer tool when it was the actuall brass trimming tool that had the problem.

YMMV.

Brass can exhibit different stages of hardness. Some gets work hardened over time, some is just harder than other brands, out of the box.

Depending on how well your flat faced cutter cuts, you might get some chatter regardless, but a good quality deburring tool should remove any burrs from the inside and outside of the case mouth proper.

I've trimmed/deburred some cases that were hardened and I had an imperfect bevel, but those are rare birds.

I use the Wilson deburring tool, the Lyman VLD tool and on my RCBS Trim Mate, I use their campher and deburring tools. All work pretty well.

A reloader just wants a clean bevel on the inside/outside of the mouth, so don't go all 'caveman' on the process.

Time is better spent elsewhere.

Re: Outside Neck Chamfering

As you have found out, the speed of the rotation makes a difference. The drill press works well because you can use different speeds. For instance I have found that the Possum Hollow trimmer likes 900 rpm.

Re: Outside Neck Chamfering

Unlike many here, I gave up on the std outside deburr tools. I could not get a nice clean cut. So, I tried out a large fine toothed flat file and have been using it for the last 5 years.
Just slowly spin the case as you stroke the flie at an angel acorss the neck: 3 Strokes does the whole neck.

Re: Outside Neck Chamfering

I have had the same issue with the outside burr on cases. I bought a brand new Wilson tool, and it did a teeny better job, but still left a burr. The only way I have managed to get rid of 100% of the burr is to clamp my variable speed drill in a vice, run a 4 inch grinding wheel in my drill at a low speed, and slowly rotate the case while holding it at an angle to the grinding wheel. It takes about 10-20% longer than using a de-burring tool, but it gets rid of 100% of the burr.

I have tried running the de-burring tool in both directions, and at variable speeds, and to put it bluntly, they simply don't work well for me.

If I'm turning the outside of the necks while trimming the necks, the outside neck turning tool removes all the burr too, but that is a different operation than simply trimming cases.

What doesn't make sense to me is that the inside neck chamfering tool works like I had hoped the outside neck one would. But they don't.

When you have a cutting tool inside the neck, the stiffness of the neck holds the cutter in place.

When you have the tool on the outside of the neck, the stiffness of the neck does not hold the tool centralized and, in effect, it chatters. I also had a few cases where the neck after deburring was no longer round.

Wow, I sure haven't found my RCBS to be "slow". With the carbide cutter it's down right quick.

I kind of prefer the way I can adjust the chamfer and de-burr function separately as well.



An RCBS trimmer for less than $100, a power conversion kit for under $10 and that makes it a "Power trimmer" with well over $300 left over.

To each their own.
