Judging from your comment I tend to think that you haven't read this thread from the beginning. Sounds like you may have jumped in near my last few posts. For me "Success" is defined in incremental steps. I want to succeed in actually being able to wrap my own Carbon Fiber barrels. This means starting with these short lengths of Carbon Fiber tubes then transferring them to my turned down barrels. This to me is doable by the average joe.
Like you've alluded to, turning down and threading the barrel and the matching mandrels is the easy part as far as I'm concerned. It's the traversing of the learning curves involved in applying the resin properly; the optimum pattern to lay down, how best to wind the Carbon Fiber onto my mandrels and the curing of the wrapped Carbon Fiber tubes that I'm looking for success in doing. It matters not what others who have never even tried such a project define as success. That doesn't even enter into the equation. One step at a time.
The subject of "Heat Retention" in the metal of the barrel is one I kept coming across with nearly every negative comment or opinion I read or viewed on video when I was doing my informal research in to Carbon Fiber Wrapping rifle barrels. At one point I came across a comment from one of the actual producers of Carbon Fiber Wrapped barrel. This person was fielding negative comments regarding "Heat Retention" due to what detractors deemed to be the "Insulating Qualities" of the Carbon Fiber wrapped around a steel rifle barrel. This person offered up the mathematical formulas to disprove or to take the steam out of the "Heat Retention" concerns they were continually being bombarded with. I can't remember the guys name. I think he was from Proof Research but it was a while ago so it may have been one of the other Carbon Fiber Barrel manufactures. I never did get to see those mathematical formulas but to me it wouldn't have mattered much cause I suck at math anyway.
"Success?" To me is learning how to actually do it myself. To get a lighter weight barrel. To get a more rigid barrel. To get a safe shooting barrel. Hopefully to get a accurate barrel. To NOT have to pay seven or eight hundred dollars to someone who in all likelihood learned how to Carbon Fiber wrap their own barrels the same way I'm doing here. One step at a time.
I don't really think that an apology is warranted here but for the sake of keeping the peace; sorry that you don't like my design. You may be even more unhappy to know that this design will be the one that I'll most likely go with as I traverse those learning curves I mentioned above.
