Old School cool 40X! Not sure the cartridge has a future however.
I've always been a fan of the 40X. The 22 creedmoor will be around forever.
@@DustinDrews1 Doubtful. Look at all the failures of the last 19 years. How many 22 bores are there? Way too many. Short fat cases feed like rocks. No one says anything until. they own one. Then it is too late. Do you even know what Creedmoor is? Most do not. Marketing is to blame for all this bullshit smoke and mirrors.
If you generally thread the muzzle you can make a custom metal piece that threads on and the hose quick connects to for you fluid through the barrel. Only downside I would see is the need for it to be two parts because of the barrel spinning
I drill and tap a short set of pipe threads. The pipe threads have been 100% leak proof
Been a machinist for 35 years and 100% agree with how you did this. Nice job! I'm guessing customers keep you busy with the top notch work you do!
Thank you for the kind words! I'm glad you approve of the work! Have a Blessed new year
It looks like you have spent a lot of time “working out the bugs” of the process. After working as a toolmaker since 1966, I would like to see one major change made in your headstock work holding. Is there a reason why those long hex-head cap screws need to protrude 3” from the tooling body. These are the things that can send a man to the hospital, or to the morgue. Please give some consideration to replacing the meat eaters with socket set screws, that are nearly flush with the fixture surface. This not an attempt to hijack your program, but to save you and others from the potential consequences of getting caught in unrealized situations. I have some of the scars from my education on shop floors. The net has quite an assortment of accidents in machine shops. Safety glasses, short sleeves, bare hands,long pants, and safety shoes, are what I have found to keep me alive and well when and not if the fecal matter hits the fan.
I 100% agree I need to shorten the bolts. Thanks for sharing your knowledge!
@@DustinDrews1 You are very welcome. I have been very free with what I have learned, either the good or the bad. I can’t take it with me at the end.
Thanks for another sleepless night thinking about this. What I figured you are saying is that the set of bolts on the head (chuck mounting side) control the radial runout. You dial in the barrel to be concentric with the lathe axis (centerline) at that point. Then the other set of bolts (tailstock side) is used to dial in the angular axis (centerline) of the barrel at that point (second point) which is now offset from the original concentric point. By dialing in this second point to the first, this alignment will make the entire barrel axis (centerline) run true to the lathe axis (centerline). So now the barrel and lathe are concentric. Using simple (non-machinist language) removing the taper from clamping the barrel to run true with the lathe. The distance between the first and second point being greater would increase this accuracy. This is why you didn't use a buck chuck. And all this time I thought it was a hole in some steel that a bullet went through.
That's pretty much how it works. Thanks for the comment! Sir, you better take a nap… you sound like you may need it! Any other suggestions let me know
Nice work mate. Are the horizontal bolts that clamp your own adaptor to the lathe adaptor plate set to a certain torque that allows the two to be slid across the faces by the radial jacking screws, without needing to loosen or tighten the clamping bolts? You didn't mention anything about needing to make adjustments before or after radial jacking, and I can't see any access for that. I assume the cap screws visible in the face of the 3 jaw chuck are just for mounting the chuck itself?
Thank you for your comment! The Omni Adjustable Spider Adapter is mounted to the lathe just like any other chuck. It bolts to the A2-6 adapter plate using countersunk bolts that are hidden under the chuck itself. While it shares similarities with a Buck Chuck or Set-Tru Chuck, what sets the Omni Adjustable Spider Adapter apart is its independent adjustment mechanisms. The radial runout is adjusted by 8 screws that push against the lathe mounting plate, while the angular runout is controlled by 4 spider screws-similar to a cat’s head or spider on a traditional lathe spindle. Since the 4 spider screws are mounted in the adapter that moves radially, the radial and angular adjustments stay completely independent of each other. Adjusting one does not affect the other, making it an innovative and precise tool for dialing in your workpiece. Hope this clears things up! Let me know if you have further questions.
@@DustinDrews1 so the clamping force of the countersunk bolts is overcome by the radial jacking screws, allowing the two faces to slide across one another?
Yes, just like a set true chuck
Can you do a video of the contour work?
I guess I could. Honestly the tl1 is not a lathe i would recommend in anyway shape or form to do contouring. I got mine to work fairly consistently. But that being said a person just can’t look at what I am doing and expect the same results. Like shown in the videos I normally post. To many little work arounds to deal with during the process.
Awesome video. What model CNC lathe are you using? Thinking of jumping in with a CNC and skipping the manual lathe. This video was very informative.
It’s a haas tl1. I have a love hate relationship with it. Cnc stuff is not cheap and the learning curve is steep, never ending and not forgiving. Not saying you can’t do it. But it’s been a year and a half journey to get here. I say this not to scare you… I here to help but just to give you a realistic perspective.
Nice work Dustin! Looks like you really have that CNC dialed. Do you think that your chuck would be a worthwhile investment on a manual lathe? Or is the old school spider still good enough?
We keep improving! Time and rigidly is probably the biggest benefit. It would definitely help in a manual machine. Especially if you’re having to do short barrels in the headstock. Thank you for your comment! The Omni Adjustable Spider Adapter is mounted to the lathe just like any other chuck. It bolts to the A2-6 adapter plate using countersunk bolts that are hidden under the chuck itself.

Interesting design. Always enjoyed your videos. I use the Viper Chambering Fixture and it's been working very well for me on my small 12x36 lathe. It holds the barrels very well and I've never had chatter issues.
Glad to hear the Viper fixture is working out well for you. With 2 sets of spiders holding the barrel over 6 or so inches you should be plenty rigid. One neat thing this chuck adapter does is moves the chuck and the spiders radially. At the same time. Unlike your spiders when you adjust one typically moves the angular run out.
I wanted to get back to you about what I was thinking. Sorry about slamming you on the chuck. Safety should be first. Anyway, this is basically a buck chuck. Buck chucks come with three up to six jaws. Extremely accurate and very pricey. A lot more compact is advantageous for rigidity. If you can scale yours back to act as a buck chuck, just throwing it out there. What keeps me up at night is how you loosen the bolts to adjust the runout without it falling off. When I use my four-jaw doing repeat parts, I mark two jaws as the adjustable the leave the other two fixed. It works well and the parts repeat. For your that too time consuming. Time is money, maybe incorporate a collet closer in future design.
Thank you for your concern… But I don’t think u fully understand how it works. The Omni Adjustable Spider Adapter is mounted to the lathe just like any other chuck.

Nice to have some new videos posted, thank you and Merry Christmas
Merry Christmas to you too! We are going to do a lot more videos. Now that we have our process even further dialed in.
Beautiful work as always
Thank you so much 😀 excited to do so 20 gt builds
No borescope?
lol I completely spaced it with the editing! There will be more videos I promise!
I like this it would be a good setup. I only do my own barrels it would be interesting if i can make this work on my little 1440 grizzly. With how light weight my lathe seems i dont know if i could spin pass 460 rpms which is about the limit i do now threading
This would work on your grizzly with out any issues. It looks heavy but in reality it’s really not that heavy. And it will get lighter once it’s shortened. Threading at higher RPM on a manual lathe is pretty simple. Research “threading away from the Chuck” you do this by running your lathe in reverse. And holding your tool insert/holder upside down. Holding it upside down and running in reverse allows you to start the cut where it normally ends against a the shoulder. It is the only way to thread in our line of work. Inserts and holders. Get a top notch positive rake insert. With a left handed holder. Kennametal is where I got mine. The positive rake inserts really help with the slower manual machine speeds
The quest for perfection never ends. I have some questions about your reamer holder system and its adaptation to a manual lathe using the tail stock as the feed. I now use a higher end adjustable floating reamer holder and want to switch to rigid tooling. Your system appears to be the way to go. I'll be calling you tomorrow.
Forget about using the tail stock. A tail stock is basically a boat anchor on a lathe for gunsmithing. It is slow, it does not repeat, and it flexes under pressure. Use your carriage! You will have to invest in some tool holders. But once you do you will never go back! And if you have a digital read out all the better! Headspace is a breeze. Looking forward to the conversation
Can't argue with those results. Would be cool to see the fluting on the mill. I like watching this stuff. Was thinking about recutting a .223rem to a 22 creed, nice to see you already have the reamer.😉 Barrel I have is a 12 twist Savage 26inch heavy varmint. Was removed because of a boogered up chamber. Was cutting marks into all my brass. Merry Christmas!
Merry Christmas to you too! I will do some fluting on the mill. All you wonderful customers are keeping be busy with the barrel work it’s hard to keep content posted.
@DustinDrews1 hey that's a good problem to have. With that Haas you've got it dialed in, helps knock out jobs a little quicker hopefully.
It’s been a blessing and a curse. But we are getting the curses worked out
You should use set screws, not bolts . Should never run a lathe like that. I can't begin to explain all the very bad things that can happen. You shouldn't even be showing that. Seriously bad idea.
Thanks for your input, I appreciate the concern.
Looks super dangerous to the operator without guarding
Yup, it’s a machine tool… A person has to be vigilant
Nice work mate. I really enjoy watching you constantly thinking and innovating 👍
Thanks 👍 Im pretty Stoked how this has turned out.
Looks like it could serve a dual purpose of plucking chicken feathers. 😊
No this one will only work for ducks and geese! Have a Blessed Christmas
Good solution. I like how you're always innovating. Question on bore straightness. Do you try and finish the shoulder so the bow of the bore is up or down when torqued to the action? Or are the blanks straighter these days?
I’m not convinced the “bow” of a barrel it is a thing these days… If what people say is true about a being clocked up or down to shoot flatter… If the barrel was not clocked it would shoot left or right at distance and you would have to dial in adjustment at range to hit right and left. Know one ever talks about this or dials for it. So I don’t think it is a real thing. Just something to talk about.
@DustinDrews1 thanks 👌 Merry Christmas to you and yours.
Have a Blessed holiday season
Have a blessed holiday season!
That looks very impressive. Very nice work mister.
Thank you very much!
Dustin, you’re running a CNC lathe now. If I’m running a spider on the end of my spindle and my four jaw chuck, would that not eliminate barrel flex due to the contact points on the barrel and the linear distance between the points? Also, I have considered a True Bore alignment system but after handling one I am reconsidering due to the weight and stress it would apply to my spindle bearings. My 1340, I believe, is just too light of a machine for the True Bore and I would assume the same to be true with your Omni set up. I give you the final word.
If you can support your barrels on the back of Your lathe you solved the issue with rigidity.! The issue I solved with this chuck system is not a manual vs cnc issue. It is a spindle length issue. Many lathes on the market these days have too long of spindles to be able to support a barrel at the end of them. These long spindles help make the lathe more rigid. But hurt in the function of doing barrel work. Or if you’re working on a short barrel this can be an issue even on your short spindles lathe. Another feature in this system is one barrel adjustment movement does not affect the other. Like it does with your 4 jaw system. Also you can use any self centering chuck and turn it into a set-tru/buck chuck or radial runout adjustable chuck. By adjusting the 8 radial runout screws. Weight is a concern of ours also… Currently, it’s within a pound of the Trubore System. I can’t remember which is lighter, but I think it was our system. This being a prototype, I made it longer than it needed to be. I wasn’t sure if 6 inches of barrel support would be enough, so I added 2 sets of spider holes to extend the distance between the chuck jaws and the spider screws. The final offering will be shorter by 2-3 inches by removing front set of jacking screws. And just shorting the chuck adapter 2 to 3 inches. This should make it substantially lighter. Let me know if you’d like any more things explained
@ Thanks Dustin.
Anytime
thank you for posting this ive been getting into gunsmithing with my 1940s atlis lathe making pistol caliber stuff im too inexperienced to think about rifles but learning anything about chambering online is difficult
Glad to hear you liked it. Old lathes are sure cool!
Good job on that, But for your morse taper stuff, After a while you will have scratched up your precision surfaces enough to affect their accuracy.
You are correct. But the time they save me will more then pay for replacement of Them.
Looks good, except your method of alignment for the reamer is totally wrong. As a toolmaker, we are taught that everything has droop. But a magnetic base on one end of parallel and the test indicator on the other end. Zero the test indicator. Flip it upside down and the dial will change because the setup is flexing or 'drooping' You'll easily get 10 - 20 microns droop. As toolmakers, we have sneaky little tricks to get around this problem. Nice to see you had a go. I can see what you've tried to do, but sorry. Fail.
Have you ever chambered a rifle in your life? Do you have any way to personally measure 20 Microns in a chamber? Do you know how much a floating reamer holder droops when you remove it from the chamber? Thanks for the comment! It helps my channel grow
@DustinDrews1 Dustin, I do my own chambering. Yes, measuring a micron is easy, I use a micron indicator daily as part of my work. It's an essential tool aligning jigs for jig grinding. I'm not disagreeing with ridged reaming, it's the only way to get an accurate hole but it requires a very accurate setup. I disagree with how you set your indactors up. It's not an accurate method. It would take less than a quarter if an ounce of pressure to deflect the bar in your setup and it definitely weighs more than a quarter of an ounce which means gravity is going to deflect the bar and skew your readings. Otherwise your stuff isn't too bad.
Isn’t to bad, i will take that as a compliment. Thanks for your input have a blessed holiday season
Bill, I am interested in how you would go about mitigating bar droop in this situation?
Indicator droop is real. Maybe a co-axial indicator?
Been doing this for years and had a nail pull out the other day and caught in the jaws when it fired causing the trap to stay open at a 45° angle. No more nail bedding for me. Had the nails placed the same position and angle as yours. It costed me a catch. Lesson learned.
What a beauty! Excuse my ignorance, but did you need to re-barrel it? Couldn't you have re-chambered the 22-250 into 22CM without installing a new barrel? Or was the Wilson barrel the intention all along? Cheers
The rebarrel was the plan all along
Hermoso trabajo
Thank you!
Did the you have to tinker with mag to get it to feed, or did the 308 mag work?
No it fed great
Quick tip on reamer chatter - wax paper wrapped around the reamer will usually do the trick. Run the machine as you would and wrap the reamer with the paper and send it home with whatever holder you have. Worked very well for me.
Thank you for sharing! But the key is never allowing it to start.
I dig the pneumatic follow rest. Are you still using that for profile cutting?
I still use a pneumatic rest. But more of a stead rest now
Chamber is perfect. 👌 I appreciate the look at the program side as I'm trying to teach my old brain CNC stuff.
It’s a long haul
many thanks Dustin for video.
They are fun to do!
Changing it up. Improving the process. 👌
That is exactly what we are doing! Expect another video soon about our new chuck system we designed exclusively for chambering rifles. The after chambering about 100 or so barrels with this system i can confidently say this was the missing link in our process. Thanks for watching!
Getting around to viewing the different methods on barrels. This is a great blend of production, precision and feel. Can tell it's not your first rodeo! Thanks for sharing.
I definitely would not use this method if you’re trying to copy it. Our latest methods are far superior
What book would you recommend to learn how to chamber a barrel pls
Without knowing where you are at knowledge wise I don’t know where to tell you to begin. Gordy Gritters has a few educational things out. But I have found that much of the information found online and in book form is just regurgitated information from years passed. The process of chambering is laughable to do as a machinist. But to get consistent and repeatable results is a costly undertaking. I will be producing lots more videos in the future. God bless, Dustin
I personally like my TRAK -1845 RX due to its conversational style programming while still being able to upload cam software to the RLX control
How long you had your trak
did you check the bracket for sag? clamp to round stock zero on top the roll 180 and see reading on the bottom, to see amount of sag.
The bracket is extremely rigid. We have to draw the line somewhere. Short of using laser eyes and such I’m not sure what else a person could do to take this measurement.
I like it but seems that measuring for runout using a dial indicator as shown is a mute point as the rigid reamer would act like a boring bar. There is no give so it would cut concentricly no matter if it was on center or a smidge off. Seems you would have to measure the chamber diameter instead to see if it was cut oversized? Maybe you thought of this or have some way to measure this or confirm that it isn't? Great idea. I may try it. Thanks.
You are correct. You have to ensure it is square to the bore. That being said all the floating reamers on the market only float radially. Not angularity So if you’re not lined up perfectly parallel to the bore with a floating reamer the same thing happens. But no one thinks of this being an issue because it has the word float in it
@@DustinDrews1 Haha! I never see some of the old timers that keep telling me to use something like the "bald eagle" reamer holder because of the "feel" - ever post their runount on youtube for all to see. Keep up the good work! Have you thought about making your adjustable reamer holder out of a shank like Gavin uses and just putting 8 screws (4 front and 4 back) in it for adjustment?
Awesome video enjoyed it!
Glad you enjoyed it! Thanks for watching
Love this idea!!!!! Thank you for your tip and "how to" video!!!
Glad it helped, now go get some coyotes!
Where did you get your swagger?
Very professional machine work. I will be contacting you soon about my next project. Liked your video 👍
I look forward to hearing from you!
A lot of flaws in this guys logic. 1st of all he is chucking with a 4 jaw chuck directly on the area to be machined. For the barrel to be held ridged there has to a certain amount of chucking pressure. So when he un chucks that barrel there goes his so called perfect roundness! Even steel is elastic, see Robin Renzetti’s videos, he clearly explains this fact. # 2 he is using Interapid test indicator which are notorious for SAG! Simply reading the directions that come with these indicators is all in has to do to verify this. Lots of threads on the practical machinist website discussing this known fact. Master barrel maker William Large chambered barrels using a steady rest with precision roller bearings. To this day it’s the proven most accurate way. This guys barrels may shoot great but when people make perfect roundness and TIR claims I call BS!
Thanks for sharing your thoughts. But When turning long or slender workpieces on a lathe, many machinists might assume using a steady rest is the best way to support the part. However, in many cases, clamping the part directly into the chuck without a steady rest is actually better. Here’s why: 1. Improved Accuracy: Using a steady rest introduces potential points of error due to misalignment. By clamping directly into the chuck, you’re securing the workpiece more rigidly and reducing the chances of deflection, which leads to better precision and tighter tolerances. 2. Consistent Surface Finish: With a steady rest, the pressure applied by the rollers or jaws can cause marks or deformities on the surface, especially on delicate materials. Clamping directly into the chuck eliminates this problem, allowing for a smoother and more uniform finish across the entire workpiece. 3. No Interruption in Cutting Path: Steady rests can obstruct the cutting tool’s path, forcing you to stop and reposition the part or tool. By skipping the steady rest, you avoid these interruptions, saving time and ensuring a continuous and uninterrupted cut. 4. Reduced Setup Time: Aligning a steady rest properly takes time and effort, especially when working with multiple diameters or shapes along the length of the part. Clamping directly into the chuck simplifies setup, reduces complexity, and speeds up the process. While there are situations where a steady rest is necessary (for extremely long parts or those with very thin diameters), for most applications, securing your part directly in the chuck is more efficient and yields better results. And I would bet money that If we used any type of measuring equipment that you could arrange. My methods would have less runout than using the steady rest method chambering method. God Bless, Dustin
Fantastic workmanship
Thank you very much!
What chuck system is that to be able to dial in radial and angular runout?
This on is the Tru bore system. I actually am going away from it. I’m moving to a design I built that holds the barrel more rigidly. The true bore is a neat system but it really needs a spider of some sort to hold the barrel from whipping and flexing the chuck. My lathe has to long of a headstock to do this. Thanks for watching
What made you switch back to a floating holder? Why the jgs over another brand?
I still prefer to do rigid reaming.
awesome!
Thank you! Cheers!
