As Super 91 has pointed out already, getting good vane adhesion is going to be difficult and take some extra time and work to over come. Please allow me to attempt a simple explanation as to why this is happening. Some people have stated that PSE has come back with a statement that the manufacture is not using a good glue. This is only partially true.
Bob (Super 91) and I are both aware that a few years ago PSE bought out a very large arrow manufacturer named Carbon Force. Carbon Force is now a division of PSE and the producer of the TAC Arrows.
This said, PSE did not exactly lie, they just didn't explain the entire story.
Next, The TAC arrow shafts are being created from a brand new type of carbon known as Carbon Filament. Carbon Filament has some very positive features that make it exceptionally strong, very straight and having no specific glue spot that typically creates a stiff line which we know as the arrows spine.
These new properties make spine identification much more difficult than in the past, but creates a superior arrow shaft to those produced in the past.
All this means that the manufacturer is now attempting to bond two materials together that have not been bonded previously. This is unique plastic like materials that make up the composition of the Duravanes and that of the filament woven carbon fiber of the PSE TAC15
Please keep in mind that when an arrow manufacture buys materials to produce arrows, they are buying in huge bulk quantity. This includes glue as well as the other components, so it takes a while before they can replace these things and replace them with others.
In simplest terms, we all want our arrows to work well and hold up, but in archery arrow maintenance seems to be a way of life and it's probably a good idea to get a fletching jig to replace lost or torn vanes. Super 91 has already stated that he's been having good luck with Dorn's glue and I am certain we will need some time and everybody's help to test out some different glues until we find what works the best over a several month span of time.
Please just make sure that before you re-bond any vanes onto these shafts that you clean down the shafts very well with denatured alcohol on a cloth. A little goes a long way, so all you need do is wet the cloth and wipe several shafts down by wrapping the wet cloth around the shafts and sliding it back and forth a couple times. Let the shaft dry standing up for 10 - 15 minutes and you are ready to place your arrows in the fletching jig and start gluing your vanes back on.
Nothing says that you need to use an instant drying glue. You can always use slower setting glues like "Fletch Tite Cement" or "Duco Cement", then there's "5 Minute Epoxy" and to many others to even begin to mention here.
If all else fails, you may want to even try using natural feathers instead of vanes. Natural feathers weigh 4x less than vanes, are more wind resistant, but will require more care since they are not as tough. Each time you change the materials being bonded together, you are likely to encounter different results.
Once again, let's give credit where it's due; Super 91 does more experimenting with many of these variable than the rest of us put together, so if you're not inclined to do any experimenting yourself, I would recommend following his lead on what to use, since he has documented more than anybody else I'm aware of.
