I ordered a carbon fiber sleeve for my maverick 700mm barrel. I'm going to epoxy the sleeve to my liner. My question is has anyone also epoxied the barrel housing the carbon sleeve as well for extra rigidity? I do not plan on changing calibers or changing liners. It has a superior heavy slug liner and that will be all this gun ever uses. Any potential downfalls I don't see besides the fact I will have to remove the entire assembly as one solid piece to remove the barrel?
Maverick epoxy liner to sleeve and barrel housing

Should provide extra support but before you go though epoxy I would test it all out lose to make sure your slug choice agrees with liner. I have the same setup and never epoxied the sleeve but my sleeve was really tight. When I swapped from superior to superior heavy the carbon liner stayed in the sleeve, that how tight it was. I also added a tensioning system too. Message me if you want pics

Well I have about 20-30 different slugs to go through but so far the barrel shoots them pretty well. I actually just received my bullet central tensioner and I haven't had a good test of it yet. I believed I have originally tightened a bit too much and it was all over the place so I backed it off some and seems to be a bit better. I plan on adding a barrel band as well. Going for a rock solid repeatable shooter at high power.

I gotcha. I had actually torqued the small set screw to 25 inch lbs and it seem to work really well. I made my tensioner before bullet central came out with there well Ernest’s design and had Donnyfl machine me an adapter and it’s pretty hard to over tighten that one. Since all I’m able to uses is a small Allen to tighten.

If you are going to epoxy it, make sure it's REALLY THIN epoxy. Some have use loctite, make sure it's SLOW setting.

Was going to use the golf club shafting epoxy I have on hand. Should be ideal and not set up too fast. I also have some shafting glass powder/beads if it isn't a super tight fit.

I believe Ernest Rowe used on of the Loctite products in his video where he adhered the cf sleeve to the liner. Found it - here it is:

Coming from the Aerospace Industry, where bonding things is a daily occurance, it sounds like you have a VERY...good handle on what and "how" the bonding of your barrel and carbon fiber sleeve need to be accomplished.
The use of your glass beads will put you WAY ahead of most of your peers in completing this task.
Continue with "your" plans.

Well I would like to think I have a handle on the actual bonding part. I just wanted to see if any bonded not only the sleeve to the liner but also the exterior of the sleeve to the barrel housing tube. I think the glass beads will just help me keep things aligned better.

I've never heard of bonding it to the sleeve. Keep in mind you're making it a 400$ permanent setup compared to 100 and change setup. So just make sure its the liner you want.

Yes for sure that was my first thought. The whole purpose of this gun is to be super high powered and shoot heavy slugs as fast and as accurate as I can. I bought the superior heavy liner for that job and it seems to be doing good so far. The stock liner is good for stock power and pellets but I'm not building a plinker. Definitely have to have my ducks in a row to make sure I assemble it correctly.

I haven't been able to measure either the barrel, they aren't round, or the ID of the sleeve. But they are a slip fit. As the barrel isn't straight either so that will affect the feel of it going on. I tried some JB Weld and let's just say there was a certain amount of puckering going on as I impressed upon the barrel that it would go on, yeah, that tight. YMMV. We'll be intrested to see how that shafting epoxy works.

It seems like it would be ideal. Golf clubs heads are put under quite a load along with impacts of course. The epoxy never really gets stone hard. It rather has a tiny bit of flex left in when fully cured.

As my CF sleeve are a light suction fit to my barrel in the Maverick i see no reason to glue it in place.
BUT ! on the outside of the CF sleeve and the barrel pipe i have a substantial gap, i will estimate something like 1 mm, at least i have several full wraps of tape on the CF sleeve in 3 locations to make it not rattle in the barrel pipe ( when barrel not fully assembled ) i found this more easy than getting 3 even thinner O-rings like the barrel are originally mounted.
I have replaced the factory shroud as i have upgraded from 600 mm barrel to 700 mm, and a full upgrade here with FX parts are wayyyy too expensive, so i got a 100 mm barrel pipe extension and then i have replaced the factory shroud with a carbon fiber "shroud" made of 3 CF pipes fitting inside each other and then on the factory barrel pipe, and still have the same OD as the FX shroud.
There are however 1 downside to my DIY "shroud" those CF pipes are not laser strait, so i have to "clock" those pipes on the barrel to properly line up POI with my POA
But once that is done my .177 Maverick are shooting well at 50 to 100 M, but it is a extra think i have to be mindful off when i have had the barrel off the rifle.
I do not want to glue the CF "shroud" to the barrel pipe as it is a light press fit just like the 3 individual CF pipers are, so really once clocked the right way it are not going anywhere.
The 3 pipes are glued together in the rifle end, CUZ i found that taking the barrel out they would some times slide instead of sliding them all off the barrel pipe.
When shooting my moderator have a firm grip on things.
I always remove my whole barrel to clean it, taking the straw barrel out are just a mess, so do not do that any more, but loosening the 2 set screws at the breech and pilling the whole barrel are nice and easy.
