Fx impact 700&800mm barrel torque system mods

[@HBMINIFUN]

Hello I have been working on this project for about 3 weeks now. I watched Ernest's videos on how to put your barrel under tension to help with barrel droop and harmonics. I purchased the 14mm x 20mm 3k carbon fiber tube that he used in video and cut it leaving about 1mm longer on the length but then I was stuck trying to figure out the size and thread of the liner lock witch after talking to FX USA it's a 13mm x .5 pitch on the threads witch is micro threads. I hunted down a tap from McFaddendale hardware witch was special order and $25.00 but then I was in a position that I also wanted to be able to use my moderator so I needed 18×1 threads to put moderator on so things were getting more complicated so reevaluated the situation and came up with this. I took old .357 shroud and went to my buddies shop where we chucked up the original shroud and bored the cone out to 20mm to allow the 14mmx 20mm carbon tube to slide onto the barrel leaving about 1 mm longer then barrel length and laving the 13 x .5 treads from the liner lock exposed so now I slid shroud over the 14x 20 carbon fiber tube that is full length of barrel and the shrouds now can screw back onto the liner lock and tension the barrel. I will get some pictures of what it looks

[@bdog3869]

Jason were you ever able to get some pictures posted. Would really like to see what you came up with and how you did it. Very interested and thanks.

Hi Ernest, I have a. 22 impact with 700mm barrel. I noted that sometimes the POI as shift and I found the solution... Put a rubber ring between the sleeve and valve house and it improve a lot the accuracy and the barrel is always ridged and no more shifting of POI

[@DrSaminstine]

Great video I have done just what you show here and it is great!! Been testing it as well and it’s a tack driver! Also you can unscrew the back adaptation plate on that Donny and leave that on that’s what I do. The internals of the Donny stay just fine and it still fits in the case.

[@ernestrowe5061]

Smart man!

[@christhomas4260]

Or FX just fit a proper barrel. Customers are spending a fortune on Mods and improvements that should already be on the rifle. I own two and like them but enough is enough . POI shifts and liner indexing is a PITA . A LW barrel will shoot slugs and pellets so why these flimsy barrel systems. Removing and replacing the Mod causes a shift .

[@BT-st4ho]

Than way you buy a second FX…

[@woodsman2433]

One hell of a difference there Ernest. All the best

[@n1iex]

NICE mod Ernest thanks and are you going to have this available to us?? Thanks!

[@David-fd6ex]

So where do I get the carbon tube?

[@outtoride]

Awesome, great idea. I think tension is more accurate than torque. Torque is applied to tighten the moderator, but the force resulting on the barrel is tension. ❤

[@texaspst968]

I think the word your looking for Compression. Tension is when somethung is being streched.

[@klausswartz3369]

I may be misunderstanding, but the desired result seems to be to tension the barrel to increase stiffness, thereby eliminating or minimizing barrel whip, ie harmonics.

[@outtoride]

@@texaspst968 you are halfway correct. the barrel is being stretched, pulled under tension by increasing the number of threads in the moderator. the carbon fiber outer is being pressed upon thus pulling the inner barrel tight under tension.

[@texaspst968]

@@outtoride You are absolutely correct, the barrel is under tension while the carbon fiber sleeve is under compression. Thanks for mentioning that. I was not clear.

[@elite1299]

Great work sir We need this Hope you will get this ready fr sale soon

[@coreymoyers]

That’s how internal suspension bridges work. You can add a bushing that is calibrated to compress at the tension you want. Another solution is heavier/bull barrel. Is that something you would ever consider making? I bet it would help people in competition even more so if they don’t already know how to tune for harmonics.

[@JoePatABC]

Hi Ernest: The problem I see here is that if you've taken the time to "align" your barrel liner properly so the high point of the liner is at the 12 o'clock position, when the carbon fiber tensioning sleve is torqued down, since it's tight against the liner it will turn the liner thereby ruining your liners alignment. :/

[@ptescreen18]

jmpdgs I thought fx mark the barrels so u know what the top is , all mine have come with marks on them

[@raymachado44]

I would like one on my 35 cal impact

[@chrissnyder8625]

I have the Emperor moderator were can I get the adapter to do the carbon fiber mod for my .35cal impact?

[@landonemory7902]

Is there a way to put the shroud back over the CF sleeve? Then the shroud would work as your tension nut and it would also look good lol. I feel like it would work as long as you could open up the cone end of the shroud to match the OD of the CF.

[@HBMINIFUN]

Ernest could you tell me what size and thread pitch the tensioning plug is that holds in the inner barrel?

[@HBMINIFUN]

For anyone else looking for this info I called FX USA yesterday and they gave me the info. The tensioning liner lock size and thread for a FX .357 sniper barrel are M13x.5 witch is super fine thread and I have verified the thread pitch with a thread pitch gage from Snap-on and it is .5. Here is a link for a M13x.5 tap www.hdchasen.com/metric-tap-m13-x-5. I'm in the process of getting a adaptor made that will keep my barrel tensioned at all times and can remove moderator to put gun in case.

[@paulandrews3785]

you ar a legend on set up of fx guns make s lots of sense your video s well explained to cheers has helped me out a few times cheers

[@kellypace1534]

Interesting...... as are all of your mod videos. But for some of us who live in apartments and are without a shop or access to one, it's just something else interesting to watch. It would be great to know if there is a supply source for these carbon tubes, cut to spec. that we could purchase. Looks like an easy mod but for guys like me, guess we'll have to stick to the o-rings for now.

[@FTChile]

Well done my friend, cheers from Chile I do this 10 years ago, and continúe doing this to this days... Work fine for heavy silencers and a lot of poi drop

[@jackdaniels7913]

Nice work once again, my only thought is I'd like a second sleeve to bulk it back up to approximately the same diameter as the standard shroud... just a personal cosmetic thing something about the skinny/ naked barrel that just doesn't look as good to me, but I do like the way you think, always something worth are time and money from you thanks again! 🥃cheers🍻

[@Premierslugs]

So this torque is actually pulling against the barrel index grubscrew ? I have a lothar walther.20 barrel on one of my impacts and it really really shoots

[@benjaminrobinsonrobinson7998]

Hi enest I'm just about to change the barrel on my mk3 wild cat I have a compact soi want to shoot slugs so would my my best be be a 600mm serpoier heavy liner be the one to get and what would be the best power to shoot fx hibrids thanks so much I have learnt so much watching your blogs hayd.

[@chaseyourdreams4104]

Just purchased my first impact m3 30cal for right now I've got the factory moderator on it how do I get a tensioner sleeve

Great! now lets us know when FX's gonna start making mod carbon for the Dreamline so we can have ours.

[@chenglo8999]

What length is needed for the 357 fx barrel??

[@mariomorales2061]

Why can't FX use this concept together with the barrel tuner? Ernest: Don't you think putting these 2 mods (barrel tensioning to reduce droop and harmonic tuner) together will give FX customers the best solution for not using the solid barrel?

[@toddlish1892]

How much is the cost for the outer carbon fiber as well as the inner carbon fiber that you siliconed the the barrel liner to. I would be interested in placing and order for both of it is not an extreme expense.

[@toddlish1892]

I spoke to Jessica at FX today and you were in a training meeting. But she did say that these carbon fiber kits might be available in a week? :-). Oh hell yes!!

[@robingibson7503]

OK, where do I get this mod? It seems like the more "mods" I put on my PCP the worse my accuracy! Especially after it came back from Utah Airguns!

[@sambaaxe]

I like that! DO you think there is any way that this trick could be applied to Crown Continuum?

@earnestrowe what’s the exact size of cf tube thickness and diameter do I have to order

[@pst2147]

Really great idea!

[@corny155]

So I have pcp that I’ve done this same method of barrel tensioning. However, I’m seeing poi shift in hot to cold temps.

[@ernestrowe5061]

That’s normal for metal and CF expansions and contracts- summer hot to cold temp have to rezero -

hello i dont have an fx factory to play around in where do i get this tube please?

[@rotary5428]

Tried out the carbon mod on the liner and it worked wonders! What ID would you recommend for this mod? Is 14mm ID too tight?

[@ernestrowe5061]

20mm OD 14mm ID

[@DrSaminstine]

14x20mm would be my guess and he had to sand the id for a snug fit.

[@DrSaminstine]

Most of my barrels are a heavy 14mm and the tube was right on. Or vice versa depends on calipers but I had to sand either way. Well worth the effort. Now I am working on the same thing over the shroud with thinner material. It is compressed into the lip around the shroud and is showing even more promise as far as accuracy and damping controll. The outer carbon uses the same principle as the inner barrel and rubber o rings are used to fill the gap and absorb vibration. Next level!

[@DrSaminstine]

For over the shroud is id 30x32 od mm was used with O ring spacer filling gap. Keeps it light! Looks tight. Cut 1/16 long and hand torque. Amazing accuracy.

What ever happened to this concept? I’d like to give it a try.
