    I haven't a clue what tool you're talking about but, for a factory rifle, getting anything fancier or more costly than the Forster HOT-100 neck turner is meaningless.

    you can look @ 21centuryshooting,com .Not turning for a factory gun ,A nesika k custom with a krieger barrel .290 chamber 6.5x284 ,Lapua brass. Just getting into the turning thing (newby) as you guy's would say. Been reloading for 20 years just trying to get into better groups. Also have a 6mmbr built on a stiller predator action w/schilen barrel had it built w/no turn chamber would it help to turn the necks on these?

    I use the Sinclair tool and an RCBS trimmer and it seems to work just fine. A neck turner is a neck turner, if you ask me.

    I just purchased a 21st Century Neck turner with the lathe setup. Anything that makes turning necks faster, easier, and more accurate is worth it's weight in gold in my opinion. I'll let you know how it works out.

    For years I have used the Sinclair NT-1000 hand held. Takes me about 4 hours to turn 100 cases and that is after tool setup. And then my hands and wrist ache for a week.

    Check out this video on the 21 Century.

    I don't have my speakers hooked up. But from watching the video, it appears that the head that holds the cutter rocks back and forth while he runs the drill.

    If I can see that in a tiny little window, then it can't be good for tolerances.

    I've used my Lyman trimmer with the neck turning and power screwdriver attachment for quite a while with satisfactory results. There's certainly no discernable wiggle while it's cutting.

    My main complaint with the Lyman is that there's no micrometer adjustment. So, it's trial and error for any new setup.

    I sure wouldn't mind something better if it doesn't break the bank or cripple my hands.

    Richard,

    Both the head and the tool "float" in the lathe" this allows the mandrel to precisely align the case and cutter head. Go to their web site and listen to the video and he explains all of that. It's part of the tool design.

    He claims +/- .0004" accuracy in the neck thickness. We will see. I will let you know how it works. I was never able to get near that good with my Sinclair hand held.

    My kids stole my speakers. So, the cideo didn't do much for me. I'll look at the website.

    Your explanation makes more sense.

    It would be nice if Cabelas or one of the local shops carried decent gear so that you could examine it more closely.

    I've got way too many useless gadgets. So, I'm keen to hear what you guys determine.

    thanks!!
    Richard

    I will sure let you know how it works. I am not one to hype a product just because I have it.

    I know what you mean about the stores. They are just full of useless Chinese junk!

    Sad.

    The mini-lathe has unique fittings on the left and right sides that allow both the case-holder and the neck-turning tool to float. As a result this tool maintains near-perfect concentricity during the cut. 21st Century’s John Perkins explains: “The floating design of the neck turner and the case driver allows the case mouth (bore) to run on the arbor absolutely concentric, therefore allowing O.D. to be turned concentric with I.D. The tailstock creates a horizontal inline support for the base of the case. This also allows the operator to keep both hands on the power screw driver or drill, making it very easy to control the feed rate and to produce a very fine, turned finish.” Having the system float at both ends was key, according to John: “By allowing both the turner and the case to float, everything self-aligns. This maintains concentricity and allows the unit to work with very low torque.”

    It's alotta hoopla..
    While I'm sure it works good enough, there is not actually a 'better' turner than those offered by Sinclair. And you can use any of the case lathes out there. If you can't turn brass right with a Sinclair, then give up on turning..

    I think my current case lathe is a neilson, and I hold an NT4000 in my hand for 'perfect concentricity'.

    But just to break down the hoopla, you can visualize the 21stC angles produced by supported points to cutting point.
    The casehead is supported so all the wobble is seen at the cutting point. The turner is back supported, so all the wobble is again at the cutting point. Now draw a line in your mind between both supports, and from either of the support points to any wobble at the cutting point. See the angles? See that the case neck is not straight w/resp to the mandrel?
    The only way to keep it straight is to completely suspend(in your hand), either the turner, or the case. There is no better way.
    But this'll fool folks I'm sure...

    Always amazing how shooters are motivated to buy reinvented light bulbs, yet they never bought into to the original light bulbs. It's as though 'new' is assumed better.

    I have used mine to turn 100 Winchester 308 cases and getting ready to turn 200 Lapua 308 cases. The lathe is very fast and accurate however, you must still start with a concentric case. In my recent experience, this is very easy with Lapua but almost impossible with Winchester brass.

    The INSIDE of of the case mouth must be concentric with the body of the case before turning. To accomplish this, I have gotten good results using a precision full length sizing die such as Forster Bench Rest or Redding Comp dies. Then running the case mouth through an expander mandrel.

    This procedure has given me in the range of +/- .0004" variance on the neck thickness and less than .001" runout on loaded rounds. I expect better out of the Lapua brass.

    I can highly recommend the 21st Century Shooting lathe and their other products as well.

    I own and have been using a Sinclair hand held turning tool for years. I get faster, easier, less fatiguing and just as accurate if not more accurate necks using the 21st Century Lathe. But those are just my actual results using both tools.
